The Acer Aspire One has a built-in BIOS recovery routine, which can boot into a minimal BIOS environment via a special boot block to re-flash the BIOS, even if the system does not pass POST and does otherwise not boot anymore. This is also known as crisis disk mode.

First format an USB flash drive with FAT. It does not need to be bootable.

Download the latest BIOS, and extract all files from the zip file. Put both FLASHIT.EXE and the BIOS file with FD suffix in the root directory of the flash drive. The files must not be in a folder. Rename the BIOS file to ZG5IA32.FD before proceeding. It only works with this exact filename.

Turn the AA1 off, with the flash drive still connected, and make sure both battery and AC adapter are also connected.

Press Fn and Esc simultaneously, keep them pressed and press the power button. Release Fn+Esc after a few seconds. The power button starts blinking at this point. Press the power button once. The AA1 will now initiate flashing the BIOS. After a while the button stops blinking, and the AA1 reboots shortly after. Wait patiently.

If it doesn't reboot by itself, but keeps blinking, wait at least a few minutes before turning it off, and try again.
