The process of removing a BIOS password is long but not impossible. I've tailor made a solution fit exactly for your predicament.
Important (Please read befor you proceed)
Whichever method you choose when flashing, the BIOS not only the password, but also all the other configuration data will be reset to the factory defaults. So when you are booting for the first time after you have flashed the BIOS, you should enter the CMOS configuration menu and fix up some things. When you boot Windows, it may happen that it finds some new device, because of the new configuration of the BIOS, in this case you'll probably need the Windows installation CD because Windows may ask you for some external files.WARNING!!!
Make sure your laptop is unplugged before opening it up. Ground yourself before handling any components inside a PC to reduce the risk of electrostatic discharge.If you don't know how to configure your BIOS, don't mess with it. You can damage your PC!! Rather get a qualified technition to hep you.There are a few ways to reset the BIOS password as listed below.
•Using a manufacturers backdoor password to access the BIOS.
•Reset the CMOS using the jumpers or solder beads.
•Removing the CMOS battery for at least 10 minutes.
•Using a professional service.Standard BIOS backdoor passwords
The first and easiest way to bypass a BIOS password is to try one of these standard manufacturer's backdoor passwords: AWARD BIOS
AWARD SW, AWARD_SW, Award SW, AWARD PW, _award, awkward, J64, j256, j262, j332, j322, 01322222, 589589, 589721, 595595, 598598, HLT, SER, SKY_FOX, aLLy, aLLY, Condo, CONCAT, TTPTHA, aPAf, KDD, ZBAAACA, ZAAADA, ZJAAADC, (eight blank spaces), ALFAROME, ALLY, ALLy, aLLY, aLLy, aPAf, award, AWARD?SW, AWKWARD, IOSTAR, CONDO, condo, d8on, djonet, J256, J262, j262, j322, j332, J64, LKWPETER, Lkwpeter, PINT, pint, SER, SKY_FOXSYXZ, SKY_FOX, syxz, SYXZ, TTPTHA, ZAAAADA, djonet, %øåñòü ïpîáåëîâ%, %äåâÿòü ïpîáåëîâ% AMI BIOS

If you have access to MS-DOS
You can reset the BIOS to its default values using the MS-DOS tool DEBUG (type DEBUG at the command prompt. Do it in pure MS-DOS mode, not from a MS-DOS shell window in Windows). Once you are in the debug environment enter the following commands: AMI/AWARD BIOS
O 70 17
O 71 17
O 70 FF
O 71 17
Invalidates CMOS RAM.
Should work on all AT motherboards
(XT motherboards don't have CMOS)
O 70 2E
O 71 FF
The first letter is a "O" not the number "0". The numbers which follow are two bytes in hex format.Resetting BIOS via hardware (CMOS jumpers and CMOS battery)
If you can't get into Windows and the standard backdoor passwords didn't work then you will need to flash the BIOS via the motherboard's hardware.NOTE:
Please read the important note at the begining of this section before to try any of these methods. Using the jumpers to reset the BIOS password and settings
The best way to flash the BIOS via hardware is to plug, unplug, or switch a jumper on the motherboard, (if the jumper is normally on position 1-2, you have to put it on position 2-3, or viceversa). The 3-pin jumper should near the power supply on the motherboard, typically labeled "clear cmos" or "reset bios". To find the correct jumper you should read the motherboard's manual.
Once you've located the correct jumper, switch it (or plug or unplug it, depending from what the manual says) while the computer is turned OFF
. Wait a couple of seconds then put the jumper back to its original position.
If after flashing the BIOS, the computer won't boot when you turn it on, turn it off, and wait some seconds before to retry. Removing the CMOS battery
If you can't find the jumper or if it doesn't exist, you can remove the battery that keeps the BIOS memory powered. It's a button-size battery somewhere on the motherboard.
The laptop CMOS battery is shown below.
Disconnect it for 15-30 minutes or more, then reinsert it and the data in the BIOS memory should be reset. If at first it doesn't work, try to remove the battery overnight. Once the battery has been reinserted power up the PC and see if the reset was successful.
