Password locked BIOS

HP Elitebook 840 G3
Microsoft Windows 7 (64-bit)

I have a HP Elitebook 840 G3.

I need to replace Windows 7 with Windows 10 - however the BIOS is locked so I cannot get access to change some settings needed to get a new OS installed.

I have forgotten the password.

Password locked BIOS



Unfortunately, there is nothing we can do to help you, since 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.

Most HP business notebooks including the one you have, do not generate system disabled codes.


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


HP issued this document recently...


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.
