How to rescue your Acer 7720G from bios update failure
Se till att du får tag på rätt bios bara.
Saxat från en annan tråd, annan metod med crisis-boot:
WARNING! Flashing BIOS is very dangerous if you don't know what you're doing. There are external factor that we cannot control to ensure such process will 100% success. The only thing we can ensure you is that the modified BIOS image is properly build with zero warning & error. We will not responsible for failed BIOS flash or any other failure. Use it at your own risk.
Good news is, there is a way to recover from failed BIOS flash or corrupted BIOS. To achieve this, we will require a Crisis Recovery Disk. Crisis Recovery Disk is the final fail-safe mechanism to recover the BIOS. The BIOS recovery procedure can be found at the bottom of this post. Keep in mind, the hotkey & procedure to recover corrupted BIOS may varied between different model even it is from the same manufacturer. Believe me, I know.
CRISIS Disk (WINCRIS):-
Acer Aspire 9420 BIOS Recovery.rar
Only need to replace the "BIOS.WPH" file with yours. Make sure the BIOS.WPH file is the one working with your model. Preferably the original BIOS image file. The BIOS.WPH file in the package is for Aspire 9420 (also compatible with: Aspire 7110, Aspire 9410, Aspire 9410Z, TravelMate 5110, TravelMate 5610, TravelMate 5620)
EDIT: If below process is unsuccessful, please create CRISIS disk using floppy disk or USB flash drive & with option "Compress The Bin File" selected. During the recovery process, DON'T press any key, just in case.
This is step-by-step BIOS recovery which is works for me:-
1) Download Crisis Disk maker above.
2) Create Crisis Disk using WINCRIS (need a floppy disk or usb pen drive/usb flash drive).
3) Remember to replaced the "BIOS.WPH" file with yours. It is important to rename the BIOS file to "BIOS.WPH".
4) Take the battery and the power cord out of the laptop.
5) Hold in Fn+Esc, take in the power cord and then press the power button (without releasing Fn+Esc key).
6) The USB floppy drive/pen drive/flash drive light will flash as it reads the BIOS file from the disk. You can release Fn+Esc key.
7) While in recovery process, display will always blank.
8) Recovery process will take a while (a minute or two). Laptop will automatically restart when recovery process succeed. You should see POST after restart.
Lycka till förresten!
