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
stored in CMOS memory that is maintained while the PC is powered off by
a small battery, which is attached to the motherboard. If you remove
this battery, all CMOS information (including the BIOS password) will
be lost. You will need to re-enter the correct CMOS setup information
to use the machine. The machines owner or user will most likely be
alarmed when it is discovered that the BIOS password has been deleted.
On some motherboards, the battery is soldered to the motherboard,
making it difficult to remove. If this is the case, you have another
alternative. Somewhere on the motherboard you should find a jumper that
will clear the BIOS password. If you have the motherboard
documentation, you will know where that jumper is.
If not, the jumper
may be labeled on the motherboard. If you are not fortunate enough for
either of these to be the case, you may be able to guess which jumper
is the correct jumper. This jumper is usually standing alone near the
battery. If you cannot locate this jumper, you might short both of the
points where the battery connects to the motherboard.
A. By Using the Motherboard Jumper:
In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.
Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.
When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.
Make sure to turn the PC off before opening the cabinet and resetting the jumper.
B. By Using Software:
I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

Clearing a BIOS password on a laptop takes a little bit more effort than a desktop. If you are comfortable opening the machine then I will post back more detail but if you are concerned about your warranty or are worried about the safety of your motherboard, professionals are in the best option.

You need to reset the BIOS password. One way is to dismantle the laptop. Once you can see the board, look for a battery that is similar to watch batteries but is much bigger (the circle flat kind). Remove it then put it back again. It will reset the BIOS settings on the computer. The tech guy would be just doing the same thing.
Hope this saves you $200.
