I have also killed my Acer Aspire 7720 when attempting to upgrade my bios. I have downloaded the following files: ftp://ftp.work.acer-euro.com/notebook/aspire_7720/vista/Bios/v1.45.zip, unzipped to an empty USB. Removed battery and AC. Held down Fn+Esc, put AC back and press power button. However, the laptop did not power up.

I have all three files from the archive on the USB drive.

Also tried renaming the .fd file to ICL50HW.fd, as explained here: Bios Recovery On Acer 7720 - Other Computer Related Discussions - The Elder Geek on Windows, still, the fan does not turn on.

Maybe it is important to say that when I failed flashing and I restarted the laptop, it was just showing a white screen and wouldn't turn off, so I forced it by removing the battery.

If useful my previous BIOS version was 1.29. Here is how it looked like before I killed it: https://www.dropbox.com/s/sx8u2fmslzki553/20130929_200031.jpg

Hello,
I have an Acer Aspire 7720z with a corrupted BIOS and I'm not able to boot from the USB stick (that's what it look like). I waited 10 minutes without success.
I used a 2GB USB stick formatted as FAT.
These files I have copied to the USB stick:

BIOS.WPH(BIOS file for my laptop, just renamed to BIOS.WPH)
PHLASH16.EXE
and
MINIDOS.SYS

I used WINCRIS.EXE to create the disk.

Does someone has any ideas? Please let me know.

Hi,

To increase you chances of getting help, I strongly suggest you create a new topic.

If you speak Dutch, change the language on the top corner

Good luck

It looks like there should be only ONE FILE on the USB flash drive.
ICL50HW.fd

I suggest you remove the other files and try again.
