Tonight I tried to turn on my little Acer Aspire One A150 (put its full name in just to help searchers) netbook and it’s power light came on but other than that it was totally dead, the BIOS failed to display and there was no hard disk activity.
I was really shocked as it has been brilliant so far and is less that 12 months old. My first instinct was just to go and get it’s recipt and get it boxed up to go back.
However while it sat in the naughty corner ready to go back to Acer I discovered this chaps page. http://www.qrpcw.com/2009/01/acer-aspire-one-bios-recovery.html genius!! Not sure how this guy discovered the method especially with the BIOS file rename but it works, she’s now purring away again and working perfectly.
Incase that site is un-available for some reason I will post the instructions here, just with a note that while it worked for me I could not guarantee it will work for everyone. For me the fix was complete in a few minutes and everything was restored.
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 pen disk with the FAT filesystem – Do this on another PC going to “My Computer” right clicking on your USB pen disk and click format, then choose “FAT” as the file system. Do a full format not a quick one.
- 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 sure that it isn’t still flashing the BIOS.
Also while looking into this I discovered how to make a USB pen disk a DOS boot disk, which is NOT REQUIRED for the above but handy.http://www.bay-wolf.com/usbmemstick.htm
