Question about Computers & Internet
I had this problem before with my old laptop. I had to contact customer support and prove that I was the owner of the laptop and they reset it for me. If you can't prove you are the owner you will have problems. There are a lot of master passwords out there for different BIOS's, but none worked for me.

SOURCE: Bios Password Reset
The only idea I have is to find and disconnect the CMOS back-up battery after removing main battery and unplugging the AC adapter. That SHOULD clear the bios completely, wiping out the password, the date, and everything else.
I know this works on desktops, and most laptops, but no promises, and the cmos battery may not be easy to access.
You should probably leave the battery unhooked for at least 1-2 minutes to be sure it clears.
Hope this is some assistance!

SOURCE: how to reset password
To set the bio password, follow the following:
As soon as your laptop powers up, hold F2 until the ACER logo appears. Now press the right arrow on your keyboard twice to go to the: "MAIN" tab. Now press enter. You will be asked to enter the new password twice along with the original one. (if you previously had a password.). Now scroll down to where it says either: "Enabled" or "Disabled". If it is: "Disabled", press enter and select "Enabled". Exit the BIOS saving changes.

To reset the bios you need to open your laptop you can see there a jumper which is there is a small name (CLRSCR means clear cmos)beside the jumper you need to get it and turn on your laptop with in 5 seconds then turn it off, after that you reinsert the jumper, then turn on your computer and see if there is a bios password. "good luck"
