Hello! I need help.
I lost my BIOS password on my work notebook. The last employee had an administrator password to all settings of BIOS. But my account has read-only access. I need to turn on virtualization technology but I can't do that. Please, help me to get access to all settings.
Model: HP Elitebook 840 G1
Product number: H5G26EA#ACB

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.
