Bypass BIOS Password....

DISCLAIMER:

This hack is not for newbies, home hacker. So, if you do actually encounter problem with bios password you should contact professionals.

actually, there are several backdoors for cracking bios password.Bt i haven't tried all this on any laptop.

> reset cmos using jumper

> remove cmos battery for atleast 10 minutes...

I have actuallyremoved cmos battery to reset my bios password. I think it is the most easy & safest way to reset you bios password. Bt it doesn't guarantee at all, beacuse the latest motherboards use capacitors to save the password, bt you can remove the battery for atleast 24hr and then try.

Taking about reseting jumper is a bit complicated bt has higher probabilities that you can bypass the password. Actually there are jumpers on any motherboard somewhere near processor or the loaction will vary with the motherboard producers. Before resetting you should carefully read your motherboard manual. Actually what you will have to do is to reset the jumper that will name like CLEAR , CLEAR-CMOS,-CLR- or etc you got to find it on yourself and then reset the correct jumper. PLEASE TURN OFF PC BEFORE DOING ANYTHING. 

The password that we talked till now removes the password the even stops booting. What if you have to bypass password the stops you from entering the bios-setup. Well it is pretty easy.

open dos and type debug,

However, after reseting some of your drivers might not work correctly. So, you got to reinstall them, & after that all will be fine..
