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

Hello,

Your Laptop seems to be full of dust - Maybe your CPU Heat sink FAN cannot turn because if this THUS causing your laptop to heat up and shut down again to prevent your CPU from receiving damage due to high temperature.

Close your laptop lid, then put the unit on its backlcd. Make sure you disconnect the Battery and the A/C Power chord. With the emty battery slot is facing you, take note of the screw that is facing you to the right on the bottom cover. There might be others like this in the same area. The cover that you need to remove is of rectangular shape, and the largest cover.

When you have removed it you should see the CPU Heat sink and a FAN. This is the part where you blow the unit out at that spot with compressed air so that the dirt will no longer block the heat from venting away from the laptop mainboard/cpu.Please check if the CPU FAN is still turning licenly. If it doesn't turn or very difficult - replace .

[ADVANCED]
Then, remove the 3 screws from the CPU heat sink and thereby remove the HEAT sink completely. Remove the CPU Heat sink FAN and clean it as nessesary. Use a small flat to switch the CPU from closed to open and remove it. Then clean it with a cloth and ethanol - make sure you remove all dirt and old heat sink paste on top if it. make sure you do not touch the bottom of the CPU and handle the pins carefully.

When you are done, place the CPU back and reaaply a eyedrop of fresh heatsink paste onto the CPU, lock the CPU switch again. Then clean the backside of the CPU heat sink where it rests on the CPU. When you are done with that, place the CPU heat sink back onto the CPU then screw the 3 screws back onto the CPU heat sink and onto the mainboard. Keep the sequence in mind. Reconnect the CPU Heat sink FAN to power on the mainboard with the cable then place the cover back onto it. Tighten all screws again and reconnect battery and A/C Power chord.
