Acer Aspire One BIOS Recovery Method
It happens. You switch your Acer Aspire One on, the power light goes on, but the screen stays blank.
Luckily, Acer have a little trick up their sleeve, that allows the BIOS to boot sufficiently to load a BIOS update from a USB flash drive, and re-flash the BIOS.
Quick Summary
Prepare a FAT16 formatted USB drive
Download a BIOS update from Acer
Put two files from the update onto the Flash Drive, renaming one of them
Put the USB drive into the Aspire One
Hold down Fn and Esc when you turn the power on, then press the power button again.
The Aspire One will re-flash it's BIOS using the BIOS file on the USB drive, and reboot in working order!
Now you need the files to put on the drive
These can be downloaded from Acer's support site
http://support.acer-euro.com/drivers/notebook/as_one_150.html
Download the latest (at the time of writing, 3114) and unzip it.
There are two files of interest, one is called FLASHIT.EXE and the other is called something like
ZG5_3114.fd
That file needs to be renamed to
ZG5IA32.FD
Please note that is an I(eye) not a 1(one) between the 5 and the A
Now copy these two files onto your prepared flash drive
Flashing the BIOS
It's at this point you need your “broken” Aspire One.
Make sure it is switched off, that the (charged) battery is in, and the Aspire One is connected to the power supply, and plugged in. Plug the USB flash drive into the left-side USB socket.
Hold down the Fn and Esc keys together, then press the power button. The power button should start flashing at about a one second interval. Release the Fn and Esc keys, then press the power button once more.
