I'm attempting to flash a bios of an Acer 4752G via a USB drive formatted to fat32.

I've downloaded this file here, and extracted it to the usb drive, maintaining the folder structure - http://global-download.acer.com/GDFiles/BIOS/BIOS/BIOS_Acer_1.24_A_A.zip?acerid=634921025155312677&Step1=NOTEBOOK&Step2=ASPIRE&Step3=ASPIRE%204752G&OS=ALL&LC=en&BC=ACER&SC=...

I've plugged the USB drive in, and holding down fn + esc I turn the laptop on. All the laptop lights turn on as usual, but the screen remains off. After a while I give up and power off the laptop. Booting it up again, I'm still unable to access the bios via F2 - GRUB loads immediately and I can still access Trisquel.

These forums mention different things, but as a newb, I'm not entirely sure what they're talking about. In the downloaded file, I can't see any .fd files. Apparently I might need to rename some files.

Any suggestions?

I think they should all be in the root directory -- no subdirectories. You'll only need what's in /DOS. Copy those files to the USB key. Then again, there's very little information from Acer to rely on -- their documentation is as a rule sub-par. It's shooting at random hoping to hit the target. It's possible to brick the laptop if it's not right from the start.

I saw another combination Alt+Esc. If Fn+Esc fails, try the other one. Some posts mention a sequence 'Fn+Esc power on' [if power led blinks] press power button again briefly.

Most suggestions involve the use of Wincris.exe for Phoenix BIOS. It should tell you how to rename the BIOSsomething.WPH file. Tricky if you don't have Windows installed.

Thanks for the extra info.

What a nightmare. I'd rather not brick my laptop. It still currently works, it's just that I won't be able to install any other new operating systems on it from scratch.
