    with bare board outside do you get vga signal?

    if you got a scope you can see if the bios chip its ok before power button its press!

    aaaaaaaaaaaand if its AMD CPU recheck or change the bios battery!

    check coils and post back the voltage on each coil.

    to see if the vga chip its working I use a lab PSU and inject 1V and if its getting hot normal temp its OK
    Just cook it! It's already broken.

            i tried with SST25VF016B but all the same
            cpu and chipset get hot, but not much, fan periodically stop and start when temp goes high

                      reflowed again, no change
                      flashed ec, no change
                      flashed main, no change

                      im not much into chasing signals trough board, im giving up on this one

                      could not backup main, could not read it
                      here is ec dump and new fixed ec
                      main is extracted from official bios update, not tested but maybe someone else can test it

                      BIG TNX to all

                                Request HP Proliant Microserver Gen 8 (J06) BIOS dump to restore system firmware
                                by Ahari
                                Hi all,

                                This is my first post here (I am very new to forums!) and I hope someone can help. I am looking for a full dump of the BIOS of a HP Proliant Microserver Gen 8 so that I can get this mini server running again. (BIOS version J06 2019-04-04, chip 25Q064A). I think my board was partially bricked after a failed BIOS update.

                                I got it second hand in this state and all the normal attempts at bios restoration have not worked. I have even desoldered the chip and tried to load the actual BIOS from HP, but it is missing some parts needed to boot the system.

                                I...

                                I need a BIOS dump for the Samsung S49CG934SU monitor
                                by Habble7
                                The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.

                                Suspected Cause:
                                I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

                                Troubleshooting Attempts:

                                My Samsung Galaxy Book 2 Pro 15.6-inch laptop has no display and won't boot.
                                The charging red LED lights up, but the charging screen doesn't show any indication.
                                When I press the power button, the blue LED cycles on and off three times, then the screen doesn't turn on, and the device won't boot.
                                (I've tried removing the battery and resetting the device, but the issue persists.)

A stock BIOS is not suffiecient, as it is impossible to discover where the MAC, UUID and SerialNumber are stored. Tried with a similar board, but there are too much differences, and the stock BIOS is missing a lot of...
