Bios password unknown

Hi I have recently purchased a Elitebook 840 off a well known auction website, it has a BIOS password which is unknown by me, I have contacted the seller but have yet to receive a reply, I think I have read on the forum’s I need a file to reset the BIOS password off HP?

Hopefully the reseller knows the password, or will allow you to return the PC, because there isn't anything we, nor HP can do for you.


HP will no longer supply the required SMC.bin file that is used to clear the BIOS password.


That was the only way it could be done.


Also, removing the CMOS battery will not clear the P/W.


HP issued this document recently...


Also the forum rules were amended on 1 March 2019, which no longer allow us to help with removing passwords.


Rule 4.d...


d. No posts shall include instructions or directions intended to bypass or subvert security measures, including passwords, locking mechanisms, fingerprint scans, etc., or to bypass any safety measures.


Therefore, this topic is being locked.
