Method 2 – CMOS Battery. Most computers have a small battery installed on the motherboard called a CMOS battery. This little battery is used to keep the time and store BIOS settings even when the computer does not have power. If you decide to change the boot order, disable a USB device or even set a BIOS password. Click on BIOS. Then try to recover that BIOS version. If you can't recover it via the OS, then try the Fn+Esc USB stick method by renaming the ROM file in the extracted DOS subdirectory to JAL90x64.fd.
I have an Acer ZG5 netbook. After 1 year of using Ubuntu, I installed Windows 7 on it. Additionally, I installed a BIOS update that was supposed to fix battery issues. However, it restarted and would fall into a loop of restarting once it hit the Windows login as if it never actually flashed the BIOS.
Then I proceeded to do a BIOS restore per the instructions found here in which one copies the image unto a USB and tries to reset the BIOS by starting with Fn+Esc pressed.
At this point I did this with the correct BIOS (I double checked), but since this point, my computer never started again.
I tried to reset the BIOS again but it would not read from the USB. I even tried it with a USB floppy to no avail.
So right now I have a computer whose components work, but which only shows a blank screen when turned on but does nothing.
Does anybody have any idea what to do? Or maybe even any ideas as to what to do with the components?

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 procedure is also known as Crisis Disk.
First format an USB flash drive with FAT. It does not need to be bootable.
Download the latest BIOS, and extract all files. 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, and verify both battery and AC adapter are plugged in.
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 it once. The AA1 will now access the files on the flash drive and initiate flashing the BIOS. After a while the power button stops blinking, and the AA1 reboots by itself. Wait patiently.
If it doesn't reboot, but keeps blinking, wait at least a few minutes before turning it off, and try again.

MoabMoabI had the same issue with my friends similar model, when the 3310 version of the bios failed to flash it, I used the previous version and it worked just fine. the instructions are the same in both cases, perhaps you can try that if you still have that Aspire One.

I have the same problem, and I tried another few USB sticks and lo and behold it worked. I didn't have to press the power button after it started to flash on/off post (Esc+Fn button combo).
Fat/Fat32 does not matter and the whole process took just under a minute. You could just copy the files on an existing stick on root just as long as it's the aforementioned filesystem format. The bootblock routine on the Acer scans the whole stick for the required files.
