    Help HP Z440 workstation bios

    Good morning, the pc only turns on the front led and the fans but not from acoustic signals or other. I have already tried to change the video card to the RAM and the CPU but nothing. Could it be the bios?

    I assume it worked before?

    Have you tried a known good power supply?

        Check BIOS battery is not low, if it is, replace the battery and reset BIOS settings with hardware button or jumper?

          The battery is ok
          what do you mean to reset the BIOS settings with the hardware button or the jumper?
          I moved the jumper for the reset but nothing

              Yes, that's what I mean. Move the BIOS reset jumper. Make sure you move it back afterwards.

              Can you get the BIOS from HP? Typically they don't go bad by themselves though...

                  is this the first time I disassembled this machine, to remove the main one you also need to remove the screws under the heat sink?

                          Two different bios to try,the bios backup had errors decompiling with Flash Image Toolkit, meaning the ME was corrupt.

                                My hp z400 beeps if it doesn't post.
                                If the power button it's blue the it passes the cpu ram then GPU
                                If there is no display with blue power button the it's GPU.

                                That series it's heretic with beep sounds if something it's wrong.
                                Just cook it! It's already broken.

                                  just checking if you had tried with the same power supply?
                                  Not sure if the power supply is standard...
                                  the last time I had worked with Z400 ... PSU pin layout is a little different.

                                        Sorry for posting in an old thread, but I was trying to fix this computer and flashed "Z440 PRD_EXT_ME M60_0247.zip" by @SMDFlea. With this bios motherboard shows no post codes (and it was showing some of them with original bios), so this bios file isn't working. I built one myself using update from hp support and clean me region. After flasing this bios system booted ok.
