Acer Aspire One Wont boot

Sometimes when switching on an Acer Aspire One it shows a black screen. The LEDs may be blinking or just the power button led may be on, and usually the fan is turning. But the screen remains black.

This is a known problem on the Aspire one and is a BIOS fault, fortunately the Acer Aspire One has a BIOS recovery procedure that makes it possible to reflash the BIOS even when the Aspire one wont boot anymore.

This procedure is only meant for non booting Aspire one’s and may void the warranty on the unit, so please follow this guide as a last resort.

Format a USB memory stick to FAT16. (It doesnt have to be a big memory stick)

Head over to Acer and download the BIOS files from the support website:

Aspire One Model A150 or Aspire One Model A110

Extract the files and put FLASHIT.EXE and the BIOS files in the root directory of the memory stick.

Rename the BIOS file to ZG5IA32.FD

Make sure to insert a charged battery and connect the AC supply.

Insert the USB Memory stick into a USB port on the Aspire One.

Press the Fn+Esc keys keep them pressed and press the power button to turn the AA1 on.

Release Fn+Esc after a few seconds, the power button will now be blinking.

Next press the power button once,. The Aspire one will now preform the BIOS flash, under no circumstances should you stop this process. After a few minutes the power button LED should stop blinking, and shortly later the Aspire One will preform a reboot.

All going well the BIOS is now flashed and all the settings will be reset to default in the BIOS

  1. Any help for the Acer Aspire One D255 model?
    I am trying to reboot with linux (ubuntu) with a USB drive. I’ve tried changing the Boot order to a USB – but nothing happens.
    The same process works fine on a different computer. Thanks!
