If you forgot Windows admin password, you need to take use of PCUnlocker Live CD to remove it.So most BIOS manufacturers have a fail-safe that will show what is called a checksum of the password once you enter the incorrect password more than 3 times.

Replace the jumper to its original position. Press and hold the power button for 10 seconds to release static electricity from the system. After the Windows logon screen appears, turn off your laptop again.
If the jumper is covering pins 2 and 3, reinstall the jumper over pins 1 and 2. For example if the jumper is covering pins 1 and 2, move it so that it is covering pins 2 & 3. If there are 3 pins under the jumper, moving the jumper over one pin will change it.To remove the BIOS password, you will need to change the jumper settings. The jumper is typically located on the edge of the motherboard or physically near the CMOS battery. Locate the password jumper on the motherboard, look for the letters PWD, PSWD, PSWDCLR, CLEAR CMOS, CLEAR, CLR, JCMOS1 or PASSWORD.Open up your computer case and remove the CMOS battery.While you work, periodically touch an unpainted metal surface to dissipate static electricity. Before touching anything inside your computer, ground yourself with a wrist-grounding strap or by touching an unpainted metal surface, such as the metal at the back of your computer.Press and hold the Power button while your computer is unplugged to dissipate static electricity from the motherboard.Disconnect all external devices and wait about 15 seconds.Shut down the computer and then unplug the power cable.
