Hello,

 

my colleague disabled somehow BIOS on HP EliteBook 8440p.

 

Please help me how to reset the TPM.

I can log in to the BIOS but all BIOS password changes are greyed out.

 

Thank you for any advice.

Dear Customer,

 

Welcome to HP Support Forum and we are glad to assist you.

 

This is to inform you that all HP Business Notebooks such as Probooks or Elitebooks have more stringent security than consumer models infact they don't produce 'halt codes', the password cannot be derived from the Serial Number and the code is stored in non-volatile memory so removing the RTC cell will not reset the password in this case.

 

Please have a look at this link.

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

 

 

Hope this helps, for any further queries reply to the post and feel free to join us again
