Hi 

Just need help resetting my bios.

I'm getting 3 beeps on boot and then fail to boot.

 

Is there a jumper or do I pull out the battery?

Thank you.

I've already power cycled/hard power reset.

 

I need CMOS clearing instructions for this until.

I can see the battery but don't know where to find the jumper.

Thank you

 I am glad you got it working.

 

On some HP system you can do the CMOS reset by using the CTRL-V procedure and other systems use the 20 second method instead.

 

Follow the steps below to reset computer CMOS data.

1. Turn off the computer.
2. Press and hold the Windows and the V keys.
3. While still pressing those keys, press and hold down the Power button on the computer for 2-3 seconds.
4. Release all the keys.
5. At the completion of a successful CMOS reset, a message showing CMOS Reset (502) will be displayed.
6. Restart the computer.
7. Press F10 to get in to bios. Check Date and time.
8. Press F9 to set bios defaults. Ensure secure boot is enabled.
9. save setting when you exit



If you do not see that 502 message then :

  • Turn on the computer by holding the power button down for 20 full seconds then release.
  • Press the Power button one more time (if necessary) to start the computer.
  • Tap the ESC key about once a second after you see the LEDs on the keyboard flash.
  • Do steps 7-9 above


However, removing the battery or doing the jumper trick will always work plus it can clear any pa.ss.wo.rds
