2How To Bypass BIOS Passwords?

Posted by Harwinder Kumar at 3/27/2011 Posted in:

The basic input-output system BIOS is the first thing you see when you turn on your computer. As in school/college labs, you would have been gone through BIOS passwords on startup, but some users don't like it as it seems weird. Follow these two methods for bypassing BIOS password:

  1. Removing the CMOS Battery

    Unplug the PC and remove the battery for 10-15 minutes, the CMOS may reset itself and the password should be blank.
  2. Overloading The KeyBoard Buffer

    On some older computer systems, you can force the CMOS to enter its setup screen on boot by overloading the keyboard buffer. This can be done by booting with the keyboard or mouse unattached to the systems, or on some systems by hitting the ESC key over 100 times in rapid succession.
