      This worked, thank you very much. However now i get the message "machine is not in committed state" when booting. Any way to remove that?

                  Thank you so much. But it doesnt work.
                  I have original IC mx25l12873fm with original BIOS, y dont flash it because I'm afraid it won't work if I reprogram. Instead i bought new ic 25q128fv and i flashed original BIOS unlocked (through hp utility and this one you posted), but still capslock blinking and fan on.
                  Even i flashed original bios readed from original elitebook 25l12873fm and program on new 25q128fv but no luck.

                  Maybe ICs are not compatible?
                  I try read and write several times and compare with winmerge. (By the way bios trough hp utility is not equal that you posted)

                  Im using ch341a black with 3.3 voltage fix, SO8 clamp (desoldered) and Neoprogrammer under Win10.

                  Thanks!

                  Edit: EC IC is original, i dont touch it. If i solder original bios IC back again, laptop works fine (locked)

                      Re: HP BIOS unlock tool

                      finally i have solve my problem , im not sure if this solution has been discussed here: the original latop IC BIOS is working in Quad SPI mode (or QPI), so QE (Quad enable) bit must be enable. i locked up QE bit from the datasheet (status register) of new BIOS IC and enabled it from AsProgrammer.

                        I attached the two files.

                            Try this (128Mb chip only)


                            When you access bios, reset security settings to default.

                              Hi RethoricalCheese!
                              from what ive learned about the G6 all it needs is
                              blank VSS 32 MB and clean pwd 16MB.
                              flash both and pwd gone.. then flash 32MB original w PWD and it clears itself from 16MB recovery and DMi preserved w no pwd.
                              maybe that will help the V2 release?

                                  Hi. Any chance anyone could remove the password from my HP 850 G5 Bios.

                                  I think I have removed the correct chips. One is a WINBOND 25Q256JV and the other is a ISSI IC25LP128. I have attached the files from them. Thanks

                                        Hey guys, is there a trick to getting good data out of the W25Q256JV bios chip on an Elitebook 840r G4 in circuit? I must have read it half a dozen times each with random bits flipped. Once I manage to reliably read the data I guess I'll post it for RethoricalCheese to modify unless there is something I can do myself?

                                          You would need to desolder the chip to make reading/writing more reliable.

                                          And this version of the tool does not support your laptop.
