postheadericon Acer Aspire One does not boot / no bios / no post / power led green

Recently i came across a few acer aspire one's that wouldnt boot anymore.

No bios or post was displayed. But the power led was burning.

After sending one model for repair to acer Holland, it said they had updated the bios to fix the problem.

How do you update a bios without being able to boot your notebook ?

I found an articel at telling me that there is an emergencie bios flash thingy installed on the acer aspire one series.

qrpcw's solution:

The AA1 has a built-in BIOS recovery routine, making it possible to flash the BIOS even if the system doesn't boot anymore. It's only meant for emergencies and may void your warranty, so use at your own risk.

Follow every step carefully!

First format an USB stick with FAT.

Download the latest BIOS, and put both FLASHIT.EXE and the BIOS file in the root directory of the stick. Rename the BIOS file to ZG5IA32.FD, that's important. Do not remove the USB stick.

Turn the AA1 off, make sure both battery and AC adapter are connected. Press Fn+Esc, keep it pressed and press the power button to turn the AA1 on. Release Fn+Esc after a few seconds, the power button will be blinking. Press the power button once. The AA1 will now initiate the BIOS flash, do not interrupt it under any circumstances. After a while the power button will stop blinking, and the AA1 will reboot shortly after. Wait patiently.

The BIOS has been flashed and all settings reset to default.

If for some reason you made a mistake during the procedure and it doesn't reboot by itself wait 5 minutes before turning it off, just to be safe that it isn't still flashing the BIOS.

I tried to do this last night but I'm not sure about the flashit file? do I just download it from anywhere? and when I download the latest bios it consist of 3 files, do i put the BIOS folder onto the flash stick??

Put the bios files (flashit.exe & renamed bios file) directly into the root of the USB stick, so no folder.

download your bios from here if its an Acer aspire one 150:

inside the downloaded zip file you can find the flashit.Exe file and the bios file you need.
a million thanks

This worked like a charm.
Saved me a bunble. This happened right after reformating a machine for a friend and on last reboot after drivers the machine died.
I would have had to pay for the repair if not for this article.
Thanks, and keep up the good work
