You could search the internet for Bios Master passwords. Other than that, just pull the ac power, main battery and cmos battery and let the system drain.
If its a Windows password, then respond back for more instructions.

Just removing the battery briefly may not reset CMOS. Look for jumpers near the battery clip and if there are some, remove the battery, short any jumpers nearby.
Failing jumpers, I would suggest leaving it without battery for at least a day; some are using 'supercapacitors' and a battery.
Opening a laptop case can be daunting; be advised that after you have removed any screws from the under- & back-side, the mating plastic parts may still have molded parts that will need to be popped apart.
If the slits between the mating parts will accommodate it, an old credit card will sometimes avoid damage to the plastic, otherwise a putty (or spackle) knife will work.
Make sure you are not carrying any static charge before poking around inside; it can be a killer.
Touch any exposed sheet metal or a heatsink to equalize any charge.

This information is intended for experienced users. It is not intended for basic users, hackers, or computer thieves. Please do not try any of following procedures if you are not familiar with computer hardware. I'll not be responsible for the use or misuse of this information, including personal injury, loss of data or hardware damage. So use it at your own risk.
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
