Right in that case it becomes quite difficult. Some bios chips are able to be reset (including password) by removing the CMOS battery, (small round button battery on the mainboard). If this doesn't work. Then the bios chip itself would have to be replaced. It may be possible to hard reset the chip by shorting certain pins but that is a big risk.

You need to temporarily remove the CMOS battery from the motherboard to reset the password.

run the diagnostics of battery frm bios.. u ll find the diagnostics option wen u restart the laptop.!! if that doesn't work thn contact the acer technical support for further help. if u have the warranty of the product thn surely thy can replace with a new battery. if more thn 1 yrs had gone frm the purchase of the laptop thn remember the warranty of the battery is not valid. only the product warranty is valid
