Thank you very much ! That worked for removing the bios password ; however now the bios tells me it is blank and I need to fill some parameters (Feature byte, BIOS ID Type, etc). I see you enclosed it in the RAR file. How can I update the Bios with those informations ?
Thak you in advance !...

Sorry for missing that requirement ; the S/N is 5CG0398ZNP. Best regards !

Hi !

I initialy tried to unlock password from an HP Elitebook 835 G7 by extracting and updating the lower side Bios (replacing the NvramActiveRegn areas with 0xFF Hex Area at adress range 37000-38FF0) ; it worked quite well for removing the password. However after, I am getting a error message when booting stating "[B]Endpoint Security Controller Problem[/B]".

From various posts on this forum and youtube I understand in such cases that I have to reprogram not one but the 2 bios eeprom chips. However I could find no clear method for fixing the upper bios chip....
