Locked

HP Recommended
Operating System: Microsoft Windows 10 (64-bit)
I reset the bios by unplugging battery, but the password still remains.
When I enter the BIOS password incorrectly 4 times the system is locked, but I'm not given any numbers or keys.
I have an Elitebook 820 laptop. Please help anyone!

Hi,

 

Unfortunately,  business machines such as Probooks or Elitebooks have more stringent security than consumer models - they don't produce 'halt codes', the password cannot be derived from the Serial No. and the code is stored in non-volatile memory so removing the RTC cell will not reset the password in this case.

 

If you Contact HP Business support they should be able to send you a customised SMC.bin file which you can use at boot to reset the password.

 

Regards,
