BIOS password lock

Howdy. I wanted to remove BIOS password from the old one and put another. But I quickly typed and now the laptop is stuck. If you can help me with the master password. HP Compaq nx9420. Service tag: CND6412QHV. Thank you!

@Alex2121

 

You may also want to try removing the AC, main battery and then the BIOS/RTC battery.

You can also remove the AC, main battery and then remove the memory SIM next to the BIOS/RTC battery.

 

If there is any plastic shield under the memory remove it.

 

Look for 2 Gold/Copper looking contacts on the system board that looks like this.

Short them with small flat head screw driver. "Make sure to do it 2-3 times"

The picture shown does not match the nx9420, with motherboard "SPS-409959-001 MB".
