hp probook 4230s wont power on

[bsod]

hi all, i have a 3 month old hp probook 4530s returned. it seems completely dead. absolutely nothing happens when power button is pressed. the little led indicator light next to the power jack is dead too. so far i have tried a different battery and ac adapter with no luck. removed ram (long shot) hdd works in identical laptop. Also the little led indicator light doesn't work on the functioning laptop either not that i am concerned with repairing that. even though it is still under warranty it is not cost effective to ship this to back to hp as typically the shipping and duty make it about the same as just buying a new machine. any thoughts are appreciated .


Edit: i put the wrong model # in sorry its actually a 4530s

I would open it up and check it with a voltmeter (carefully, since it would have to be plugged in) check where you are getting power (does it go though the DC Jack? Does the DC Jack connect to the rest of the board?) If you are getting power into the board, but it is not getting to any component, you're looking at a bad board.

thanks for the response, checked the dc jack and im getting 19volts coming out of the other end of the harness so it seems like the board. seems a shame to have to junk an essentially brand new laptop. i guess i will cannibalize it for parts in the future

You really have to work on your diagnostic skills if you want to start saving these machines. Its so much more than yanking ram or a HD or doing the little CMOS drain thing. There are TONS of threads here about non booting laptops with so much information that its a shame nobody seems to read them.

perhaps you should create a sticky with all this information in it. i did a forum search for my model # but i dont have time to sift the entire sites graveyard of threads. As for my skills i have a cost effective repair time ceiling of about 3hours on a job like this. otherwise they can just get a new laptop for a little bit more. while you may have time to test every resistor and ribbon cable i unfortunately dont

As a tech you should be seeking out this info yourself and its not going to come to you on a per-model basis. You cant just do a few things and call the machine dead, if you do then many of the machines you think are dead are actually fixable and you end up doing a geeksquad diagnostic. What will you do with the next laptop you never seen before, you can't just hope to find model specific info on what to check for. You do not have to go chip level on a laptop diag, but you need to go deeper than just yanking ram and the HD and pushing a few buttons.

This is your business, you decide how much you want to learn about it. But you really should be learning more about the diag process for any laptop if you are really going to troubleshoot these things properly.

I mentioned to add this, but I was using my phone. To see if the power is reaching anywhere else the power switch is an easy place to check for voltage. If you get voltage reading across the power switch, try shorting it out, your button might not be working properly.

its probably the maxim chip on the board, usually qfn style soldered so a soldering iron wont help you there

Do you mean 3 year old or is it still under warranty?
