I recently wanted to re-setup my Acer Aspire 7250g with Linux Mint. I switched to the BIOS to change the boot order, typed in the password and i got the message, that the password is wrong. So I looked up some solutions. I tried to find a masterpassword, but there was no errorcode shown. I tried some other things, but they didnt work as well. At last i took out the CMOS battery, I restarted the pc after i put the battery back in and all I got was a black screen.
I tried to flash the BIOS, because I read that the BIOS might be corrupted. I followed the instructions of this thread; http://community.acer.com/t5/2014-Archives/Re-flash-a-corrupt-BIOS-for-an-Acer-Aspire-7250/td-p/93769 . I tried it multiple ways with this solution, but nothing worked.
I hope someone can help me.
