If your bios is an InsydeH2O

Download the latest bios update from Acer on another computer..

Save the file to a USB flash drive and rename it "bios.fd"
Remove battery and power supply from laptop
Plug the USB drive into laptop
Press and Hold "Ctrl" & "Esc" keys.
Plug AC adapter into laptop
Press power button
Release "Ctrl" & "Esc" keys after a few seconds.
Sit back and wait for your laptop to install the bios update.
It will reboot when done.

If this doesn't work, try removing your hard drive so your laptop cannot boot from it.

It almost sounds like your primary boot disk is incorrectly selected in the BIOS. On older machines, the primary disk on the primary cable had to be the boot disk, but nowadays almost any device can be selected as boot disk. Check your BIOS setting and ensure that the hard disk partition that you have Windows installed on is selected as the first boot device. Otherwise, the system may be looking in the wrong place for the OS and giving the boot error.

Acer Aspire One BIOS Recovery 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.

Hi:
Do the following exactly how it reads:

Updating the BIOS will require a USB flash drive to store the BIOS information on during the update. To perform the update to the BIOS:

1. Go here http://support.acer.com/us/en/product/default.aspx and download the latest (check the latest date) BIOS for the netbook.

2. Extract the files from the downloaded zipped BIOS file.

3. In the Dos_Flash folder, rename the BIOS file from 3310.fd to ZG5IA32.FD, in all capital letters.

4. Copy ZG5IA32.FD and Flashit.exe to the USB flash drive

5. Ensure that the AC adapter is plugged in.

6. Insert the USB flash drive into a USB port.

7. Press and Hold down the Fn and the Esc keys together and press the power button.

8. When the unit's power light comes on wait a few seconds and release the Fn and Esc keys.

9. After the keys have been released the power light will start to blink.

10. During the BIOS update process the display will be blank.

11. Let the unit run and after approximately 1 to 7 minutes, the unit should reboot and the BIOS will be updated.
If the unit fails to reboot, or the BIOS was not updated sucessfully, try the steps again. If the unit continues to fail to reboot, the unit may need service

Linux-based Acer Aspire One Non-Charging Battery Solution


STEP 1: On a separate PC:
1. Go to www.support.acer.com or http://gd.panam.acer.com/home/
2. Click on Driver & Downloads
3. Select Product Family “Netbook”
4. Select Product Line Aspire One
5. Select your Product Model i.e.: AOA150 (located under your computer, after MFG.Date:xxxx AOA 150 – xxxx)
6. Click on the BIOS tab below (don't worry if you don't see Linux listed – BIOS is OS-independent)
7. Download BIOS to a temporary folder on your PC
8. Extract and make sure you know where you put the extracted files. You will only need three of them.

STEP 2: On a separate PC:
1. Ensure a USB memory stick is plugged in and run UNetbootin by downloading and running from: http://unetbootin.sourceforge.net/
2. It will prompt for a “Distribution” – change this to “FreeDOS”.
3. At the bottom of the window ensure the “Type” is “USB Drive” and check the “Drive” is the drive letter of your USB memory stick.
4. Click on “OK” and FreeDOS will be installed onto the USB drive. At the end don't Reboot.
5. Now copy some of the extracted BIOS files onto the USB drive as well. The only files you need copy are three: go to the sub folder BIOS_ACER_3310_Windows_AOA110 & AOA150/Dos_Flash, and copy the files 3310.BAT, 3310.fd and FLASHIT.EXE to the USB stick
6. Remove your USB stick from the PC, and plug into into your switched-off Acer.

STEP 3: On your Acer:
1. Reboot the Acer and press F2 at the initial “splash screen” to go into the BIOS settings.
2. Once in the BIOS arrow across to select the Boot Menu and move the USB HDD to the top of the list (using F5 and F6 to move them up and down). (I also moved USB FDD and USB CD-ROM)
3. Press F10 to save and exit.
4. Your Acer should now boot from the USB stick.
5. The FreeDOS screen will appear with an option to select a default option. Do this.
6. You will now be presented with a list of boot options – select option 5 (FreeDOS Live CD).
7. You'll get an error message about missing CD-ROM, which you can ignore and you'll be at the DOS A: prompt.
8. At the DOS prompt go to the B: drive (i.e. type “b:”, without quotes, and hit enter – the B: drive is you USB stick) and run the the 3310.BAT script (i.e. type 3310.BAT, without the quotes, and hit enter.
9. The BIOS should now install and reboot your Acer. Click on Settings and then System to check your BIOS has updated.
10. Restart your Acer and repeat 1. and 2. above just to make sure the Boot priority order has your hard drive at the top of the screen. It will probably have reverted automatically to the original order. If not, use F5 and F6 to put back in the original order.

Acer Aspire One BIOS Recovery 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 stick with FAT.

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 safe that it isn't still flashing the BIOS.

Download WIN98BOOT.ZIP and HPUSBFORMATTER from the internet normal bootable like a dikette won't work with a usb stick

Did you try an older bios version to try and flash to that?
