          Hello,

          I also have a HP 840 G5 which powers on, Caps Lock blinks 5 times, then fan goes into fast mode
          Everything looks OK, all voltages are there except VCore (the regulator responsible for VCore doesn't get configured via SVID).

          S/N: 5CG8322JTC

          Thanks!

              Thanks! I actually learned to rebuild the BIOS image by myself in the meantime. There was a problem with ME region. Bad checksum and structure was even detected by MEAnalyzer.
              The notebook works fine with my rebuilt image. Thanks anyway!

              On first start it actually behaved the same (caps lock flashes, fast fan) but after that the fan stopped and the system started to boot. So if anyone is facing the same issue and trying the repaired bios, be patient on first start after flashing new image.

                Hi,

                I'm having the same problems as many others where the laptop fails to boot. Is it possible to clean the bios?

                Also, ME Analyzer reports Error: Detected CSE Extension 0x03 with wrong Partition Hash at FTPR > FTPR.man! on this file.

                Thanks .S/N:5CG9256VP8

                  Hi,

                  I did the same process (replacing the ME region with clean one) as I did in my case. However, I could not find the exact same version of the ME that you have in your BIOS image. So I used the same version that worked for mine.
                  Your version: 11.8.94.4494
                  I used: 11.8.95.4551

                  So don't be mad if the laptop self-destructs after booting with my rebuilt image
                  The ME Analyzer error is fixed with my rebuilt image. My error was exactly the same...

                      Hello Masters of Badcaps,

                      Need some help in fixing this bios that comes from a failed update. Now the laptop only flashes the capslock key and the power key.

                      HP Elitebook 840 G5 bios dump attached.

                      Many thanks!

                      Ray

                            For some odd reason, every time I turn it off, it doesn't want to turn back on? I have to unplug the CMOS battery and the main battery to get it to start up again. Any thoughts?

                            Tks!
