      Here's your New Bios, program that file to your 16MB chip and put your 8MB chip back.
      Serial Number: MXL6271MVM.

        Re: HP EliteDesk 800 G2 BIOS corrupted by HP bios update

        Dear All,

        Can I ask some help with my Hp EliteDesk 800 G2 pc?
        I have no display, the psu, ram modules and cpu are ok.
        2 long, 4 short beeps at startup.
        I've attached the original bios I read out with a CH341A

        Thank you,

          You should have another 8MB chip, find it and upload its content here.
          Also write your Device Serial Number.

              Your file with the name "orig_ec_bios" not good, try to read the chip again.

                  Re: HP EliteDesk 800 G2 BIOS corrupted by HP bios update

                  How can I check that the readout was correct? My SO8-CLIPS is a bit worn.

                    It will be better if you don't use a clip, you need to desolder the chips and solder it back after programming.
                    Read the 2 Chips again as @hoaca388 said.

                      The attached zip contains the current bios files. I checked them after more readout, they were binary identical.
                      (In previous reads, AsProgrammer could not read the same binary twice in a row from the same chip, now I use neo programmer)
                      Unfortunately, I overwrote the main bios a week ago in the belief that I had a correct backup.

                      Check them please

                      Serial number (S/N): CZC61194R9

                          Hi,
                          Thank you.
                          I've written the new bios and verified it.
                          -It turns on for 5 secs, turns off for 2 secs and repeats it endlessly.
                          -No error beeps
                          -No display
                          Any idea?

                                            I have 40 of these units. All of which i tried to update bios with HP's utility got bricked. All of them were bios password locked, i used the jumper thing to reset it. Couple updated bios, one of which worked fine for _ONE_ boot. Second is now mixed with rest, i don't know which it is specifically so have not retested it.

                                            All had some MESpilock failed errors on (my) first boot of the unit.

                                            Hello all,

                                            I'm facing a strange issue, I do have my old bios where i can find some information about the laptop SN, build and so on for the DMI encoding.

                                            I did flash a new bios on the laptop and i have tried all the tools found everywhere on this forum and other forums but i'm unable to update all DMI info in the BIOS. I still get an error saying "Warning: Machine is not in committed state".

                                            Could somebody guide me on this or maybe help? I'm really hoping to find a way out of this bios thing...

                                            I have a Lenovo Legion 5 15imh05a device that I bought used online. It came with a 20V 8.5A 170W charger.

                                            The BIOS version is EFCN58WW.

                                            When I turn on the device, it displays the message:
                                            "The Connected AC adapter has a lower wattage than the recommended AC adapter..."

                                            The device rarely charges the battery, and even when it does, it doesn't show that it's charging.

                                            I've tried

                                            Hello everyone, I am looking for help to make sure I am on the right track to remove lost BIOS Admin password on an HP EliteDesk G6 800 SFF. I recently purchased this on ebay and the seller is willing to accept a return but I have already installed my new HDs, NVME, and setup proxmox so I would like to keep it.
