How to reset bios password on my acer laptop extensa 4220
First you need to remove the laptop battery at the back side. Find some screw there and remove it locate the CMOS battery and jamper.

The BIOS password is\015\012stored in CMOS memory that is maintained while the PC is powered off by\015\012a small battery, which is attached to the motherboard. If you remove\015\012this battery, all CMOS information (including the BIOS password) will\015\012be lost. You will need to re-enter the correct CMOS setup information\015\012to use the machine. The machines owner or user will most likely be\015\012alarmed when it is discovered that the BIOS password has been deleted.

On some motherboards, the battery is soldered to the motherboard,\015\012making it difficult to remove. If this is the case, you have another\015\012alternative. Somewhere on the motherboard you should find a jumper that\015\012will clear the BIOS password. If you have the motherboard\015\012documentation, you will know where that jumper is.

If not, the jumper\015\012may be labeled on the motherboard. If you are not fortunate enough for\015\012either of these to be the case, you may be able to guess which jumper\015\012is the correct jumper. This jumper is usually standing alone near the\015\012battery. If you cannot locate this jumper, you might short both of the\015\012points where the battery connects to the motherboard.
