Re: HP Probook 840 G3 - BIOS Locked

There is no master password. These can be done by flashing the BIOS from a mainboard with no password, making sure you clean the ME region for the chipset. Good clean files are available on this forum, do a search. If you do not have a BIOS programmer you can order a pre-programmed chip from ebay.

Either way, you are going to have to desolder and resolder the BIOS chip.

Thanks for the reply.
So, i´ve found this shop who is selling BIOS Chips for this laptop.
He actualy sells two kinds: the main BIOS as well as the EC BIOS.
Do i need to replace both of them or just the main BIOS?

Best regards

Re: HP Probook 840 G3 - BIOS Locked

Only main bios needs to be changed or flashed.

Re: HP Probook 840 G3 - BIOS Locked

Only main, yes. It is the 128 Mbit (16MB) chip.
