To remove the bios password you need to clear the CMOS.
Open your laptop casing look at your motherboard. locate the CMOS jamper it is near
the
battery. To clear remove the jamper and turn your computer on with in 5
to 10 seconds and turn it off. Reinsert the jamper back to there proper
place and try to turn go to BIOS if there will be a password box appear.
You need to open your laptop and look at the motherboard and locate the
CMOS battery. Just remove it with in 5 minutes to clear BIOS password.
Great advice, except the CMOS battery is soldered in place in an M55-S135.
I flashed it by shorting the positive to negative terminals on the battery. Do so at your own risk.

Hello,
There are 2 ways you can reset your bios.
1.
On the motherboard there is
a small watch battery. Remove this battery along with the power cable
from the power supply. Hold down the power button to fully discharge the
system. Wait 2-3 minutes then reinstall the battery and plug in
your system. Your reset is now complete
2. Some motherboards have a 3
pin jumper by the battery. Lets say that the jumper is on pins 2 and 3.
Remove the jumper while the machine is OFF and place onto pins 1 and 2.
Power on your machine for a minute. (Note: Your system will not POST).
Shutdown your machine and put the jumper back to pins 2 and 3. Your
reset is now complete
This is a great troubleshooting
step for those of you having POST issues or no POSTing at all. Like
other troubleshooting steps, this will not always work but usually will
depending on the problem.
Please let me know if you have any further questions or concerns.
Thanks.
