      Hi,

      No, that didn't work I'm afraid. No boot at all. Put the original back and boots but locked. Appreciate your efforts :-)

                                    write the original bios with the password back onto the chip and see what happens...

                                          This sums up discussion related to Lenovo P14s Gen5 in this thread. Credits go to Sbaro and especially Maxpower3. The locked dump is attached.

                                          The device is based on NM-F871 motherboard with Nuvoton NPCK397 series controller. The motherboard also contains three BIOS chips: two different Winbond chips for main BIOS and external EC flash, and also a Gigadevice chip which purpose I do not know. The password information is contained directly in controller and thus can be manipulated by reprogramming it, so reprogramming BIOS chips is technically not required, however you may wish to make...

                                          Hello everyone, I come here to tell you my problem regarding the power-on password. It is not a bios reset demand, and i can't have any access to windows. This is the bios and power-on password that is blocking all other things.

                                          My Omen 15-dh0052nf purchased second-hand was configured with the bios password upon purchase (very simple password :P ).

                                          Having decided to sell it in order to get something more powerful, I reset all BIOS settings and set a blank administrator password. But the power-on password cannot be changed to a blank one so I let the actual password set....

                                          Dell Latitude 5520 - dump bios to obtain password

                                          Hello,

                                          I am not experienced in electronics, but I really want to check if my idea is possible.

                                          I have motherboard replaced from Dell Latitude 5520 (11th gen on i5 CPU).
                                          BIOS/UEFI access on that MB/PC is blocked by password which I want to get it know - even if I need some bruteforcing or stupid manual activities.
                                          There was no computrace activated.

                                          I was happy when I saw many posts about removing BIOS password based on .bin file dummps. I wanted to go little further - get to know the password from the dump.

                                          1. I do not know how thebios...

                                          Hi everyone, I have a HP EliteBook 755 G4 with a Biuos password.

                                          I've read the 16MB chip and patched using ​RCUnlocker_v_1_0 but seems it didnt worked, password is still there.
                                          Can you please help to remove the password?
                                          after first boot, there was an message thet firmware is restored, dont know if was suppose to happen.
