How to Bypass or Remove a BIOS Password

A BIOS password is a protection measure that can be used to stop someone powering up a computer system or making changes in some of the computers most sensitive areas. Many big name computer manufacturers such as Dell and HP lock the customers out of this area because they don’t want the customer changing anything and potentially damaging the machine (which the manufacturer may have to warranty). However, when someone like a computer technician or hardware enthusiast needs to make some hardware changes to the computer, they will need to access the BIOS. Here are some methods to be a bios password cracker, removing a BIOS password.

NOTE: Do not try to guess the password on a passworded Hard Drive. 3 wrong guesses will often result in the information on the hard drive being lost forever.

How to Bypass or Remove a BIOS Password by Removing the CMOS Battery:
The simplest way to remove a BIOS password is to simply remove the CMOS battery. A computer will remember its settings and keep the time even when it is turned off and unplugged because these parts are powered by small battery inside the computer called a CMOS battery. If we pull out this battery, the computer will forget alot of its hardware settings, including its BIOS password. This should not be performed on Laptops if you are not experienced working with laptop hardware.

Finding the CMOS BatteryAnyway, open up the computer case using a screw driver and locate the flat, circular and metallic CMOS battery. It should look something like the picture to the right. Some computers have this part standing upright.

Once you have located it, observe how the latches are holding it. There are many different ways to remove a CMOS battery but the most common way on newer computers can be seen in the picture below.

Removing the CMOS Battery

Make sure to power down the computer, unplug the power cables and unplug any USB devices if they are powered. The computer must not be able to get power from anywhere for this to work. Take out the CMOS battery and wait 10 – 25 minutes before putting it back in. The reason for this wait is because the computer can still store power in its capacitors even though everything is unplugged. The waiting period allows enough time for them to discharge.

Plug everything back in, power up the computer and enter the BIOS again. If everything went well there should be no more password. In some cases, if you get weird error messages during bootup now, you will need to goto “Load BIOS Defaults” in BIOS and save the changes to fix them.

If this method didn’t work, try one of the methods below.

How to Bypass or Remove a BIOS Password using Software:
!BIOS is a freeware utility which is designed to be a whole BIOS and security suite. It has the ability to decrypt the passwords used in some of the most common BIOS makes such as Award, Phoenix, American Megatrends, IMB etc..
It also has the ability to brute force the password (known as “blasters”). However, this method is dangerous and can result in some unexpected and unwanted results.

Note: Because of this applications password cracking abilities, some antivirus software may report it as a virus/trojan. This is a false positive.

To start using !BIOS, reboot your computer and take note of the BIOS type and version you are running. For example, If your motherboard uses Award BIOS you should look for the text “Award Medallion BIOS 6.0″ or something similar.

Download !BIOS from here and save it to your desktop. Then, open a DOS command windows by going to Start > Run and type: cmd

Once you see a black screen in front of you, type: cd desktop
You should now see something like: C:\Documents and Settings\YourUserName\Desktop>

Now type the name of the file you just downloaded, if you haven’t changed the name just type in: bios320.exe

!BIOS - Decrypting a BIOS Password
Use the down arrow and choose “Crackers” and then press the right arrow. Using the up and down arrows, select the BIOS that the motherboard is using and press Enter.

You should now see a menu asking what you want to crack, in most cases its the Supervisor or System Passwords you want to crack, so press the 1 key on your keyboard. It will then show you another menu asking how you want it to be cracked. Option 1 is pretty good so try that first by pressing the 1 key on your keyboard. You should now have your BIOS password.

Reboot the computer, enter the BIOS and try it out.

How to Bypass or Remove a BIOS Password using the manufacturer backdoor password:

On many computers (especially old ones), computer manufacturers build in backdoor passwords for their own technicians to use so they can access the BIOS when the hardware is being serviced. Here are some of the ones that have been reported. You may need to try quite a few passwords before you find one that works

    Again, good stuff. The manufacturer backdoor password list could also come in handy.

  • Jason Porter says:

    Thanks, I did not know about the backdoor passwords, I’ve almost always had success with resetting it, but the rest is good to know.

  • robman says:

    Excellent! pcstats gave me the link kudos to your alliance! Hardocp-er

  • FriendlyGeek says:

    Uhmmm, don’t take out the battery.
    Just find the CMOS jumper(it’s almost always near the battery), Then move it over for about five seconds… Then move it back, and Your BIOS will be reset. This is much faster than waiting for all the power to drain. Some newer boards even have a button instead of a jumper.

  • wooosh says:

    these backdoor passwords didnt work for me. i have a dell inspiron 1100 and have had a load of problems trying to reboot windows xp onto it. there isnt enuff space to do this and have been trying to get it to use the disk first on install but as it is obviously set different then i cant get it to run unless i can change the boot path. have tried taking the casinbg off to attempt the battery removal but cant do that as need a special topol. any help?

    Somone who knows?
    That would be great to know!! thanx!!

    ANd somone who know why its so many passwords that shows up when i bruteforcing? Which is the ritght of the 2000 passwords? Should i try each one or what?

  • Rhonda says:

    I have a dell inspirion600m. I bought a new dell laptop from ebay over a yr ago, and reg it online. Now the hd has crashed, i purchased a new one, but am locked out by an admin pw the prev owner installed. Dell was willing to send me start up cds and transfer ownership, but that’s as much cooperation as they will give. I’ve not yet found a pw that works. Any suggestions?I’ve also replaced the battery, the cord, and the adapter for the motherboard. Dell is telling me I’ll have to buy a new motherboard. Ebay is of no assistance either due to the time that has passed. I never realized til the harddrive went down that there was a admin pw. Thanks.

  • Augustus says:

    I have a Toshiba Tablet PC (R15) I ran a program that powered down the PC then I get Password= (BIOS PASSWORD) I tried all these suggestions and even unpluge3d the battery (CMOS / RTC) but it’s still there. Any help on resetting the password?

  • bios saver says:

    THE MOST EASIEST WAY TO BYPASS THE BIOS USER PASSWORD (not to enter the Bios but to enter computer Windows).
    1.When you turn on the computer you wait until it say: “Enter Password”.
    2.When the first step is done you press and hold End for about 3 seconds.
    3.While holding end press Enter and you will be on your way to Windows.

  • Julia says:

    Let’s face it, go buy a new computer,,nobody is telling us how to REALLY BYPASSS THE f passwords

  • Administrator says:

    Seems people are getting confused with hard drive passwords and BIOS passwords. If the password is on the hard drive, these methods wont help. In fact, your options are very very few if its a hard drive password. For BIOS passwords, removing the battery fixes 90% of them.

  • greg says:

    i have a hp omnibook 4150 that is passworded can u help thanks

  • Tim Bob says:

    I shall try and help thos of you that have got a bit mixed up.

    The BIOS/CMOS password can be reset most of the time by just taking out the battery from the motherboard for a few hours, sometimes only 15 mins. This can be a bit tricky on a laptop, so be careful.

    Some of you have mentioned getting a meassage that goes something like this, “THIS COMPUTER SYSTEM IS PROTECTED BY A PASSWORD AUTHENTICATION SYSTEM….etc….etc”. This is a HARD DRIVE password stored in the boot sector, NOT a BIOS/CMOS password. I so far have only found one thing that works, and not every time mind.

    If you have acces to another PC/Laptop, download and install the most current version of ‘Window Washer’. I find this a good program for keeping your temp files in check as you can set it to delete them every time you exit your internet browser. You’ll be amazed at how much space you’ve saved, just after a few days. Anyway, the section you want is on tab on the left hand side of the window marked ‘System Eraser’. This will show you, in 2 easy steps, how to make an Eraser boot disk/cd. This disk/cd will COMPLETELY erase the hard drive of any system that you boot it in, and hey presto, you have an almost-out-of-the-factory hard drive.

    Remember, this is an erasing program, NOT a formatting program, so you will still need to format the drive after, as it will COMPLETELY erase EVERYTHING. Also, if you have sensitive data on the hard drive that you are going to erase, you might want to consider setting it to the max amount of passes, around 35!! This will almost ensure that NO Delete Retrievel program will be able to get it back. This process may take severall hours to a couple of days, depending on the size of the drive. This has worked for me around 85% of the time, hope it works for you too.

  • Andy says:

    Hi

    em – why go to all that trouble? Just flash the bios and it resets to default…

    simple enough to do switch of and unplug computer. Open side case / locate the bios jumper on the MB/ generally theres three pins – the jumpre will cover two. Change it so it covers the one that isn’t and the center pin. Turn on computer. leave for about 5 seconds. turn off computer and unplug. reset bios jumper back to where it was.

    turn on computer and access bios. simple enough no backdoors, no software and no messing with cmos batteries although the latter does work on most newer machines…

    flashing the bios though is probably the oldest and easiest method to do a bios reset..

    As to the other chap with the password problem? slave the drive into another computer/recover data/format the drive – password is gone as is anything on the drive/refit (as a master) and re-install….

    seriously guys – this is computers first grade ffs….

  • Kevin says:

    Now tell me how to reset a password from a Toshiba Laptop M35-S320. I have tried all the methods on the web, I’ve tried parallet port loopback, keydisk,operate the whole laptop out into pieces and remove the cmos battery cable. There are 2 small green batteries soldered together, laptop PC is so much different than a desktop PC, the way that Andy described is so easy for a desktop PC or some laptops, but it did not work in my case where I have this Laptop M35-S320 I have tried to re-flash the BIOS, but it won’t let me because it’s not even pass the stupid BIOS password screen before it can detects any floppy drive or bootable device. I know there’s a way to short out the jumper or EPROM jumper, but I could not find this on the laptop motherboard, maybe it is somewhere that I couldn’t see it yet. If anyone has a solution to this, please help.

    Abdul, it is the BIOS Admin Passwd. I even call and ask Dell technical support. They want me to pay them 49.99 for 1 year support before they give out the passwd. I just hate them for doing that, so I didn’t pay. If you can help me access my computer I will pay you $50 buck.

    Hi,

    I have an old omnibook 4150. I’ve tried to disable BIOS password, but the damn thing still wants a password. The old password doesn’t work, nor does hitting enter or right alt + enter or del + enter.

    I’ve also tried all backdoor bios password I could find online.

    Clearing the cmos doesn’t do any good either, it just erased date and time settings, but not the password request.

    Calling HP customer support was total waste of time and money, too.

SHE HAS THE LAST PHOTOS OF HER ON THE LAPTOP BUT CANT GET PAST THE BIOS PASSWORD. I WOULD LIKE TO DO THE SLAVE DRIVE TO SAVE ALL THE FILES AND FOLDERS, THEN REINSTALL WINDOWS. WOULD THIS WORK AND IS IT DIFFICULT TO DO. I LIKE THIS SITE BECAUSE IT IS EASY TO READ ALL THE COMMENTS WITHOUT THOSE THREAD THINGS. IT IS MUCH EASIER FOR ME AS I CANT SEE VERY WELL AT ALL. THANK YOU FOR ANY HELP OR ADVICE ABOUT A SLAVE DRIVE.

    MAUREEN

    PS

    IS THIS WHERE YOU ASK A QUESTION??

  • ed goeking says:

    Maureen…I would get a laptop hard drive case with usb connection on Ebay for about $20 total, and pull your laptop hard drive,put it in the case and connect to another computer with cdrw. Find the files you want, and copy them to the cd. Maybe you could use a friends computer. My sony vaio laptop hard drive is on the right side with one screw and a slide latch, then pull it out. Take it out of the case and put it in the usb case, and follow insts they send. Photos are very important.
    Hope is answers your problem..God Bless, Ed goeking

  • eggbert says:

    I’ve just watched an interesting video of a presentation from Defcon about how to read the unencrypted bios password. I tried it on this laptop, it didn’t work but it does apparently work on others. You have to be able to boot into windows or linux so it might not be so useful. You will also have to compile it using nasm.

  • Kenny says:

    I work for HP, and if you have a system power up password on a laptop. It is customer damage when you don’t know the password. System board needs to be replaced but not under warranty.
    Had these problems before with company’s who had their employees fired but not knowing the system passwords of the laptops. And the ex-employee did not want to tell it. So they had to replace all the system boards under no warranty $$$.
    Some laptops were only 2 months old.
    Removing the CMOS battery works for the BIOS password but not for System Power up password.

  • Brien says:

    I have been reading all of the Q and A’s and I have to say this guy Kyle is a real first grade tech. First off he forgot that not everyone is as adept at computers as others. And if he would have continued to read he would have noticed everyone is speaking mostly on LAPTOP computers not a HOME pc. As fas as this being elementary level, by far also not true. I have an associate degree in Computer Science and many cert. and also I am emplyed by a firm that deals with things of this nature, and this is by far not elementary. How-ever another common fix that he forgot to mention is that you can short out the admin pass stored on the EEPROM setting, which is what HP is notoriuos for, simply by unplugging the EEPROM board and the CMOS (not bios by the way KYLE) and depressing the power button for a few seconds. If it doesnt work that way then you can also try shorting out the cmos password by touching the CMOS battery tips on the board that the battery plugs into to a seperate grounded peice of metal. Not aluminum or brass, it has to be metal. You can usually find a piece real close to the CMOS battery plug-in. Hope the info was helpful. Thanks

  • Brien says:

    Sorry about last post Kyle, Those comments were aimed at ANDY. He seems to be a really fine expert on the topic, instead of trying to help people, he is bashing and I find that somewhat disturbing simply because he is probably not a computer Savant so to say. Again I appologize.

    real hard time with Vaio PCG-R505AFE. i have searched for its jumper on the motherboard, but i guess the password will remain there forever, i also unpluged the battery, but nothing seems to relief the pain.. LOL

    What should i DO?

  • raven says:

    hey i cant reset my password.there is no jumper, tried resetting the battery as always, dint work any help..

  • Patrick CUSTO-Blanch says:

    i have a microbytes (manufacturer what do i do??? :( i dont know weres the backdoor password plz reply

  • I see this kind of response to cmos password recovery all the time and would like to add my two pennith.

    Firstly Battery removal will work if the cmos password was set up by a user after it has left the factory.

    Second, you can flash, restore to original, trip the jumpers as many times as you want and it will have absolutely no effect if the password was set up in the original bios by the manufacturer. Simply because it is protected as the rest of the base setup software is.

    The best you could do is to retrieve the password that has been created. This method will work for most secured passwords.

    Firstly what you need is a floppy drive and 2 blank disks.

    You will need to create a Win98 boot disk.

    You will need to download (AWARDBFD.exe)
    Search google for it, the one on Drivers Guide is a good copy.

    http://members.driverguide.com/driver/detail.php?driverid=134029&action=filfo&t=1

    Extract that zip onto the other blank 3.5″ floppy disk.

    My guess is your BIOS is set to start Hard drive before CD rom so, disconnect the hard drive and the BIOS will naturally look for the next bootable device.

    Boot your system with the Win98 Startup Disk.
    When you have the prompt (Make sure its the A:/) or drive letter of your floppy, insert the AWARD disk and then type AWARDBPF.exe

    Hey Presto, you will see both user and administrator passwords. Write them down and then enter Setup and type the Administrator Password

    Hope this helps :)

Please do not try any of following procedures if you are not familiar with computer hardware. I’ll not be responsible for the use or misuse of this information, including personal injury, loss of data or hardware damage. So use it at your own risk.

    A. By Using the Motherboard Jumper:

    In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.

    Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don’t have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.

    When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.

    Make sure to turn the PC off before opening the cabinet and resetting the jumper.

    B. By Using Software:

    I have found that BIOS/CMOS Password Recovery Tool is the most effective.:

    ok i have seen dell inspiron 1501 laptops on here a few times. i am helping a friend. and noticed that no one has answered the call. there is no disket drive. this model comes with a rightable dvd drive put i notice he does not have it. so no cd or disk drive will work. witch leaves usb. i did remove the nickel size battery on the mother board it is under the keyboard easy, carefully popped the cover over the power button/hinges and unscrewed the keyboard and poped it out of place. pushed battery carefully to the heavy side of the plastic and lift and it fell out of place. anyway i called dell and they charge. i have been reading googled. and found out they give you a maser password from the information that comes written on your laptop. i would use a software to crack it except the few i found are questionable at best or charge. there are no jumbers to reset and leave very few options to recover from any of the bois password lock outs. i am not paying the fellow if i mess this up so shorting out anything is out of the question. i get that idiots out there steal and such. so i guess if i am to get the answer i have to pay and pass the buck or let go of this one. my puplic email is snowcatman@yahoo.com

  • bobalou says:

    This is for Desktop Computers only.

    Laptops have an eeprom chip and it retains it’s memory for a long time.

    EEPROMS are also found in tv’s etc.
    you can unplug your tv from the wall and leave it sit for a long time but the eeprom chip keeps it’s memory.

    Another site (I forget where) said they sell the dell software that’s used by the dell service centers to unlock the password.

  • Randal Lovelace says:

    Ok – I’ve read a lot of post and tried a lot ‘solutions’ most work for desktops, few work for laptops…

    However – I’ve got a good one here, a Panasonic CF-T5 (typically called a ToughBook), it’s bios and HardDrive locked. The laptop was originally owned by a hospital, passed via auction to an employee, which then was passed to her daughter. Neither of them can remember either of the passwords. I’ve yet to get the cover off to force the reset of the Bios (as the screws in this thing have damaged two of my screwdrivers) and are very small.
    I plan to format the hard drive with Linux once I can get past the bios (as it won’t boot to an external drive/flash drive/usb drive).
    I’ll post an update here on how this went. (may also link some images of this case and it’s cmos battery location and such)

    hello,
    sir
    i have a hcl me laptop . but i don’t know my bios name which is being use by my motherboard .so how can i know my bios name .

  • Aeontechnology says:

    I have the Answer for all who need a password or CMOS password or hard drive passwords. (For windows only!) Desktop are as follows. If the BIOS is password protected, Like in previous posts, All you have to do is remove the CMOS battery and reset the jumper. Laptops on the other hand my be a little more difficult. Most can be recovered my just removing the CMOS battery for 30min others need a little to a lot more work. Some as above have master passwords that can reset to OEM. Some like most dells require you to call dell for them to try and generate a password for you if the password fails you will be required to send to dell for them to replace the motherboard because of the BIOS backup chip located on the motherboard right below the CPU (or if you are truly gifted replacing this chip yourself). If your under warranty then your fine, If the CPU was given to you just transfer the ownership on dells support website and your fine, dell will be happy to replace the board and you are only out 15 days. But if you don’t have a warranty it will cost you about $50 to acquire a temp warranty so you can get the same service. Those who don’t want to pay or have gotten there laptop by ill gotten gains are S,O,L, unless you find a way to replace the motherboard or chip. As for all hard drive passwords on desktops and laptops, you have two option, a program that creates its own BIOS to format the hard drive like SecurErase 8 or the ever famous password recovery tools that people like to use ( keep in mind that those programs need the windows BIOS to create there own so if the BIOS is locked your S.O.L. As for the second way just use a legit OS and reformat the hard drive and you will be back to square one. but remember that some ways you will loose all data and others you just will recover your lost password. I hope this was somewhat helpful to those don’t know or would like some light shed on this subject!

Kindly tell me what the backdoor password is? i tried ‘merlin’ but i don’t think it works completely. my email address is “piyushahuja1991@gmail.com”

  • German says:

    Let me just get this one straight for you all people ,first of all if you dealing with a computer laptop Don`t remove the Battery please that don`t work only thing that really works is replacing the bios chip which cost $29.99 That is for anyone having a administrator password setup in the bios system.,other option which do work with some models but not all of them is downloading the bios from HP,Dell,etc then create a boot disk written in dos system and restart your computer off the floppy disk.
    Now for those that have other message that says this computer system is protected by a password authentication system. you cannot access the data on this computer without the correct password .
    That password has been setup in the bios system but that one will work just fine if you replace your current Hard Drive with a new one,Just make sure you press keys >F2 or F12,F10.for the boot menu then chose DVD Rom.
    Althought flashing your bios that Can be very dangerously sometimes.,if you don`t have a password on your bios plz don`t flash your bios you just really mess up.
    I am a PC Technician and deal with those problems in a daily basics. ok
    Good Luck…………..
    For desktop computers those are really easy to clear your bios,just remove the jumper near the batter for about 3 or 5 seconds bingo you`re done……….okie ,dokei

  • Dan says:

    Wow, Sony Vaio PCG-R505GL, got at yardsale. BIOS is password protected. ONLY Sony customer service can help. Called them last night. They want $49.99 AND a faxed copy of a Proof of Purchase. I told them that I purchased this unit at yardsale and don’t have a true “purchase receipt”. They told me that it would be impossible, due to security reasons, to help me without receipt. On this laptop (and many other newer laptops), removing CMOS battery has NO effect on removing passwords AT ALL! You can NOT FLASH the BIOS to remove the password either. The system will NOT boot to CD or floppy or USB. What I have read is that Sony IS capable of generating a MASTER PASSWORD (after you pay) that is associated with your laptop’s serial number. So this is more of a complaint than anything….SONY, in it’s great wisdom, has completely forgotten that MANY, MANY laptops are discarded at second-hand stores, flea markets, and donated as “old and useless” all the time. But these laptops are still useful to many of us who can’t afford a brand new unit. So although it’s great for Sony to capture $49.99 to recover a lost password and make a computer USEFUL, they have NO WAY (that I know) of initiating some kind of TRANSFER of laptops program when we, the general public, comes across a second-hand laptop. FORGET the THIEVES, they are a very small part and WE shouldn’t have to live our lives based on criminals. How about a little REAL HELP for the decent people? ~just my thoughts~

    Very helpful info, I know my bios password. It is the Windows xp user log on that appears. I have no recollection of every setting up such password as I am the only user.
    I cannot get into my windows OS to disable log on screen. I don’t know my user name. I tried leaving password blank, then tried ‘administrator’ as user name and it says ‘disabled contact administrator’. I AM THE ADMINISTRATOR for goodness sake. So I contacted me now what, HA!

  • ITBunny says:

    For post:
    Please call up Dell support, provide the “595b” code and they can generate a reset password for your system. You’ll enter the password, then hold control key while tapping enter twice and it resets your settings sending you into the OS. Restart and go back into the bios to verify the solution has worked before sending tech sppt off of the phone call. Just did this for an M2400 system.

  • scampee35 says:

    This is for mth420’s dilemma. I don’t know of any programs for generating a admin passord from the service codes, but if you can find the chip on the mother board where the passwords are stored you can either replace it with a blank cmos chip for about $20 on eBay. Or you can try to find someone that actually knows what the Hell they are doing and have them show you what pins to jump to that would erase the passwords of the bios.

    Hi German!
    I have a HP dv 2940se notebook.
    I’m using it to work so, I needed to put a bios administrator password.
    After that, I updated the bios. Downloaded it from HP website and installed.
    Since that, I cannot access my bios, because the password I set up is incorrect…
    I read that you know how to fix it by downloading the bios from HP and, using DOS commands, boot it from a floppy disc.
    Could you please send me the commands and if you could, The right bios for me to install? I’m with a phoenix one. May use a CD instead of a floppy disc?
    If you want, contact me by e-mail:
    yuriko_sakura@live.jp
    Thank you very much!

  • jim says:

    This information is intended for experienced users. It is not intended for basic users, hackers, or computer thieves. Please do not try any of following procedures if you are not familiar with computer hardware. I’ll not be responsible for the use or misuse of this information, including personal injury, loss of data or hardware damage. So use it at your own risk.

    A. By Using the Motherboard Jumper:

    In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.

    Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don’t have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.

    When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.

    Make sure to turn the PC off before opening the cabinet and resetting the jumper.

    B. By Using Software:

    I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
    BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

  • John says:

    First off, the post title doesn’t specify desktop or laptop so some of you need to be a little more cautios before insulting others. Secondly, not everyone is PC tech saavy, that is why these post exists because people don’t want to pay business’s high fees for something they can do themselves. Third, there have been a few posts stating that the Dell message ‘this computer system is protected by a password authentication system. you cannot access the data on this computer without the correct password . please type in the system or administrator password and press enter’ is a Hard Drive passwaord then they had the nerve to call the people asking for help idiots. Well it is NOT a hard drive password, it is not even a bios password but a ‘System Boot’ password. The easiest way to find out if it is a hard drive password is to REMOVE the drive and turn it on, with NO DRIVE in the laptop you will still get the massage.

    Hi, I have a Dell Inspiron 1564 laptop. Recently I was just doing some R&D about the BIOS settings.
    I set a password successfully for Supervisor , User.Then I wanted to delete it.i didnt find any option for it, so I just selected the user password, typed in the current password, entered blank(i.e. jst pressed Enter) for new password, and did the same again for confrm new password. After that it shows Supervisor password and User password “Locked”. Is there any way I can unlock it? And every time I turn on my laptop it asks for my HDD pwd. Is there a way to bring it back to normal like how it was before?Please help.

    Acer laptop bios locked no o.s on HD Will not boot from cd

    The fix. Easy and it always works. Cd rom and HD in laptop remove the HD and using a external HD case 20 bucks put the HD in that connect it to USB and boot pc Now you can boot from cd cuz hard drive is not present (we moved it to USB HD ) now when you install the os to your external HD you might get a error during second part of install this is suppost to happen b.s.0.d
    simply put your HD back in laptop and reboot now you can finish the second half of xp installation and the bios dose not need to be unlocked cuz your os boots fine. I just did this with a travelmate 5520 and it worked like a dream

  • Laptop Unlock says:

    you CANT erase this password just by removing rtc battery, you have to get a master password based on the hash code .

    The hash code appears after entering 3 wrong passwords it has a 5 digit format “xxxxx”, you can get your laptop unlocked at Laptop Rebirth

  • runnerup1972 says:

    hi i have few suggestions on all of these matters first of all bios password removing is almost impossible in most cases because we are not all expert programmer when i had a problem with one of the laptops i used a program called bios password remover had to be used on boot up which i think is the best way to crack a bios password but in one of the laptops it crashed it i took it to a repair shop they told me it is not fixable anymore then i took it home taken it a part i took out the processor chip and turn on the laptop it made few noises i turned it off and put back the processor chip back and turned it on again guess what no bios password and laptop is still working still i wont advice anyone to do all that unless you are willing to lose your laptop for good lets get back to the windows password there is few ways i know how to bypass that it is all tryed and tested on lots of laptops so i am talking from experience
    1.if you are worried about loosing your stuff on the hard disk take it of then plug it in external reader which costs around £8 pounds transfer all your files at another computer then put your hard drive back and install new windows on it here you go
    2. you can install windows vista if your system is capable vista keeps your files on place called an old windows get your files out re-format with any windows you want format all old windows so they dont keep extra space on your hard drive this works with windows 7 is well
    i hope this helps

  • Gerry says:

    People please note that much of the above information is not going to work if you have a Dell Laptop and the screen is reading DATA PROTECTION password, the only sure way is to go via Dell and follow thier advice. This system is designed to help stop thieft, the pass word is in fact a secondary bios password but is in fact not written to the bios chip but rather is stored on a special chip and not as some have claimed stored on the boot sector of the HDD.
    Take care in what advice you follow as there aqre a great many fools who think because they know the difference between a laptop and a desktop, think they are a tech, if you are not carefull you can stuff your comp totaly

  • Andrew Brent says:

    Unfortunately these don’t seem to work on my Dell laptop, after googling for a bit I found loads of companies offering password recovery services but ended up using someone called “The Password Doctor” – http://www.thepassworddoctor.com… the passwords displayed on screen after paying $20, the cheapest and quickest I could find as all of the other sites said they would take 1-24 hours to send the password.
