Hi

If you have forgotten your password to log on to windows then you will not be able to log on to your profile as this needs your windows password.

If you have a sepreate administration account on the laptop you can log on with this make another user account to log on, log on with this account to create your new profile then log off, back on as admin, you should then have access to the users folder and with admin rights you should have access to copy your stuff from the old user profile to the new one.

The most common way that most of us know on how to reset or clear the BIOS password is to physically remove the power from the computer by disconnecting the power plug and then removing the cmos battery for 30 minutes from the motherboard. Another way is to reset the clear CMOS jumper on the motherboard itself. Both of the 2 methods mentioned works because most motherboards use a battery to sustain the BIOS/CMOS settings for the motherboards PROM chip. So by cutting off cmos the battery power, the BIOS/CMOS settings will be erased. Hope this helps
