Somewhere near the BIOS chip inside the laptop (each make and model are different so I couldn't tell you exactly WHERE) is either a jumper that can reset the BIOS back to manufacturer default and/or a battery that keeps the settings in the BIOS. Either change the jumper (usually to the other side) or remove the battery. That should eliminate the password for the BIOS. Remember to change your settings back to the way you like them.

LAPTOP AND NOTEBOOK RECOVERY

Most laptop manufacturers have provided additional safeguards for their computers. We are not aware of any simple BIOS recovery program that works on laptops, nor are we aware of any simple backdoor passwords for these machines. BIOS passwords in most laptops are stored in a special chip on the motherboard and the only way to bypass this password is to replace this laptop security chip. Laptop BIOS passwords cannot be bypassed or reset by removing or shorting the CMOS battery. Further, doing this may cause other system errors and complicate the recovery or your system.

It's a laptop. Unless it is 4 or 5 years old it will not have a jumper on the motherboard.

You can remove the bios battery and let you know what freeze over and it will not do anything. The bios password has been stored in a security chip. Doesn't need a battery.

If the dang thing will not access the floppy until the bios password is entered, nothin you stick in that hole will work.

Some laptops can be reset with a doggle. If it is available it can be gotten on ebay. I know the toshiba is one.

Some times you can use the back door passwords and get lucky.

Otherwise you will have to contact acer and be prepaired to send it in or provide them with proof of purchase.

Good Luck
