How to Flash Corrupted BIOS on Laptop?

[loavesfishescomp]

Have an HP g60 laptop. No BIOS screen appears. BIOS is corrupted we believe. Created a bootable USB stick with the BIOS files on it. Does anyone know the correct key combination to press upon startup to boot into the USB flash drive? Tried windows + b, fn + b, fn + esc--- nothing works. Just a black screen.

Odd thing is, when I hold the windows + b key down, the hard drive light starts to light up intermittently, though still a black screen.

Thank you in advance.

What leads you to believe the bios is corrupted?

No BIOS screen upon startup, client thinks his wife downloaded a file from a P2P site that she ran, and it corrupted the BIOS (this problem happened after the next restart)... tested RAM, removed everything (battery/cmos battery/RAM & HD), still same situation. Also, tried an external monitor; nothing.

Just a hunch, really.

BIOS keys differ from manufacturer. Whats the make and model of the laptop?

It's the first sentence in his original post.

And these suffer from the NVIDIA GPUs, so that's likely the explanation.

Sorry, I read the post twice and missed it... Its been a long hot day.

Of course if it's Nvidia bumbgate there's no point trying the BIOS.

But... since it might be rather hard to get the BIOS to boot blind to a USB and since it IS able to try and boot from the HDD, I would get a spare 2.5" drive, format it FAT and make it auto-exec the BIOS update. Although having said that, at least some HPs are meant to auto-load a recovery BIOS from a USB stick with WIN+B but the BIOS needs to have a certain name and unsure about whether FAT or FAT32 etc.

I know business model HP's generally use f9 to get to the boot menu, but if its not giving you anything on the screen its not likely that it will get to the point where you can even hit it. I have replaced more systemboards that I can count in HP's for this type of issue. So if its not the ram, processor or other attached devices its probaly going to be a replacement. I have seen the heatsink in developer level HP's cause this issue when they are faulty.

Seems like it's not a chip set problem... just a hunch again. Going to ask the client if he want's us to replace the BIOS chip. No guarantees.

Will let you guys know, and thanks.

Different BIOS's have different rescue systems - you have look them up. Some require a USB floppy drive to reflash them.

Nice logo Mobil Techie...

a USB floppy we have. Interesting it possible won't boot a USB stick. How does one know this besides googling for days?

How would I know what BIOS it has if I don't have a splash screen? (HP BIOS link for the laptop here: http://h10025.www1.hp.com/ewfrf/wc/...dlc=en&cc=us&os=4062&product=4072654&sw_lang= )
