    Hello everyone, I don't know where else to turn. I have this EliteBook 840 G6—I desoldered the 16MB chip (the one on the back) and used RC Unlocker, but it didn't work. Do I need to desolder the 32MB one near the RAM too? Any help is appreciated, thanks!​

      No, you not need to desolder the main bios chip.
      Write this EC content and you are good to go.

      P.S.
      Next time write your serial ... the ruels must be respected.

        Thank you so much! At first, it couldn't pass the verification, but after cleaning the chip, everything went smoothly... Sorry about the serial​...

              just one question: I have to leave original 32mb bin and replace only 16mb bin from you. Is it correct?

                      Thanks again. It work but I had more problems with the sound. The solution was update the bios after unlock the pass. That is for info if some one have the same problem.

                      Again Thanks for unlocking the pass. I tried a lot of tools and only you help me.

                      It will be interesting for me how you did it.... 🙂

                              Hello everyone,
                              Can someone please help with this BIOS? The laptop turns on and shows a picture, but it's extremely slow to boot; it takes minutes to get to the HP logo (without a disk), and with a disk it takes upwards of 20+ minutes to get to the point where the OS boots. I have removed only the main BIOS. If need be, I'll also post the 16 MB BIOS.

                                    This attached BIOS file was programmed on several 840G6 laptops.
                                    If this dump doesn't work then MAYBE you have other problem not BIOS...

                                      by zenius
                                      Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

                                      Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

                                      Hello,

                                      I'm using TONGFANG "GM7TG7P" model laptop for over 3 years and i'm entering the same bios administrator password everyday. My laptop has Aptio BIOS (American Megatrends, AMI).

                                      But today it's not accepting my password. I'm %100 sure i'm entering the correct password.

                                      I'm trying to reset my bios without success.

                                      I tried :

                                      -I removed the BIOS battery and main battery. Waited for a long time but it didn't work. They already stated in the user manual that the password will not be reset even if the batteries...

                                      HP Omen 15-dh0052nf power-on & bios password
                                      by Nopslide
                                      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....

                                      Hi guys,

                                      If someone would be able to provide some expertise, I'd be very grateful.

                                      BIOS Corruption - Cause
                                      So I managed to corrupt my machine by installing linux and enrolling custom secure boot keys. I did choose to enroll the Microsoft keys as well, to prevent any potential bricking due to 3rd party drivers from HP being signed with those keys.
                                      After doing that, and rebooting(it did boot, powerLED, fanspin etc.), the laptop did not give any video output on the LCD or video connectors. I think I was able to get in BIOS and trigger the beeper by pressing ESC....
