\015\012A. By Using the Motherboard Jumper:
\015\012In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.
\015\012Almost 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.
\015\012When 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.
\015\012Make sure to turn the PC off before opening the cabinet and resetting the jumper.

\015\012B. By Using Software:
\015\012
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
\015\012BIOS/CMOS Password Recovery Tool Service: http://www.biospasswordrecovery.com/
Just a heads up that this has a possibility of not working since it is normally the procedure of desktops.
\015\012
\015\012If you are confident with opening the laptop on the bottom there should be compartments. As you go opening them one of them should have what looks like a black covered CR2032 Flat Cell Battery.
\015\012
\015\012You will need to remove the laptops battery and unplug the AC Adapter. After this let it sit out for 2 minutes. Once the time is up put the clock battery back in, then the battery and finally the ac adapter once you have put the laptop compartments back together.
\015\012
\015\012Note: This works because the Black Covered CR2032 battery lookalike's purpose is to keep power to maintain the system settings. Once it loses power the chips no longer retain the information causing the BIOS to go back to default settings.
\015\012
\015\012Also Note: This may not work if the BIOS has another method of keeping the settings stored.
