Re: hp elitebook 840 g4 need password unlock

Hey guys. I'm new to this forum, and from what I've read I should be able to complete this. However, do you guys have any advice for expediting the process? I recently acquired hundreds of these laptops all bios locked. Any advice would be appreciated.

Hi,

Can i remove the password myself, i have ch341a programmer. Regards

Yes that's the point, with ch341a, you should read & save your locked firmware, post it here, and the community will repost a firmware without password. Download it and reprogram it. Then solder it back (so yeah you will need to remove the chip from motherboard before).
Regards
