Dear friends,
its just a technique and if u wish u can do it.

This is what you need:
1. Your notebook
2. An empty formatted diskette (720 kb or 1,44 mb)
3. A second computer (e.g. a DOS desktop PC)
4. A hex-editor (e.g. Norton DiskEdit or HexWorks)
This is what you have to do:
1. Start the desktop PC and start the hex-editor
2. Put the disk in drive A:
3. Change the first five bytes of sector 2 (boot sector is sector 1) to: 4B 45 59 00 00
4. Save it! Now you have a KEYDISK
5. Remove the disk from drive A:
6. Put the disk in the notebook drive
7. Start the notebook in Boot Mode (push the reset button)
8. Press Enter when asked for Password:
9. You will be asked to Set Password again. Press Y and Enter.
10. You now see the BIOS configuration where you can set a new password.

Enjoy !!!

you dont have to take the battery off, just unplug the cmos connector which looks like a stereo wiring harness.

Remove the battery, and the memory cover (1 screw), and the memory module(s). Under the bottom memory module, there is a white sticker (the bigger sticker)... remove that, and there is a small copper lead labeled J2 that looks like two E's mated with each other, you need to short the E's to each other for about 30 seconds with something metal. Put at least one memory module back in, and the battery, and try booting. If it still has a password, try again for a little longer, or press a little harder with the metal object to ensure you are making a connection.

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.
