Steps
Jumper Password
- Remember to ground yourself before touching the inside of the computer, or you will damage components.
- Jumper name can be CLEAR CMOS, CLEAR, CLR, JCMOS1, PASSWORD, PSWD, etc.
- The jumper is usually located in the corner of the motherboard and near the CMOS battery.
- Some systems will reset the password when the jumper is completely removed.
Back door password
- Some laptops use their serial number to generate passwords. Depending on the table in the More Details section of the website above, decide which number to enter.
Remove the CMOS battery
- Don’t forget to ground yourself before touching the inside of the computer, or you will damage the components.
- You can bypass the timeout by moving the CLR_CMOS jumper to the ‘clear’ position while removing the battery. As such, it will automatically release the accumulated power in the CMOS chip.
Advice
- Sometimes the BIOS jumper has a “handle” painted in a bright color for easy identification. Look at the bottom of the case. If it’s a pre-assembled computer, there’s usually a small sticker with jumpers and jumper reset locations.
- If you’re stuck, the computer manufacturer may be able to give you a “reset password” if you can prove ownership. You can apply this method with Dell computers, but there is usually a fee.
