                    600 g4 is not a laptop. You will find a password jumper on the motherboard.

                        Re: HP BIOS unlock tool

                        hi all,

                        I have 2 hp 840 G5.
                        I unsoldered the 25Q256JVEQ chips, read them through TL866II and xgpro v10.50 and then unlocked through hpunlocker.
                        then I've reprogrammed them and then re-soldered them.

                        I read the forum, and I realized that I should have checked their content, unfortunately I didn't.

                        Once the PCs started up again, they worked correctly for a day and then they started to display this message when I turned them on:

                        "Bios identity needs to be recovered"
                        “The embedded controller MUD data does not match the BIOS MUD data.”

                        Then they didn't want to light up anymore. Now nothing lights up except a white blink (7 times) of the capslock and numlock keys.

                        I also read that on this model (840-g5) there were 2 chips to reprogram ... well if I understood correctly, one "above" and one "below". Is it correct ?

                        What can be the problem ? ….

                        Thank you in advance

                            Thank you for this site, with the info i read it was good to reset my Bios.

                            I did it whit a clip programmer from china on a HP ZBook 15G2

                            Enough space to clip on this motherboard only remove the battery and backcover.

                            It works fine. Customer service HP could do nothing, i purchage this laptop by a HP dealer years ago and was in the system. To old to suport
