    AsRock H87M bootloop issue

    Hi guys!

    I've bought an AsRock H87M used. I already knew that it had this issue: when you press the power button, fans start spinning for a second, then the system reboots endlessly, until you don't shut off the psu.

    I've checked the pins on the socket and they are all ok.

    What could it be?

    Thanks in advance for the reply!

      Tried 2 PSUs, with and without RAM, with and without CMOS battery (2.95v). Cpu is the only thing I can't change because I have only one of them (1150), but the previous owner also has the same issue, so I believe it can't be the CPU.

        A memory battery under 3V is considered "spent". Check the pins on the CPU socket and see if some are bent, check and clean the ram slots with 99% IPA, take a white eraser and clean the contacts on the ram. Try using only one stick of ram.

          Thanks for the tips! 2.9v is spent for sure, but can it be a good volts value to make the motherboard works correctly?

          I have to try to clean the ram slots, because is the only things I haven't done.

              The issue is present also with no ram stick on, so I believe the ram is not the problem, in this case.

                The strange thing is that, if I jumper clrcmos for a lot of time (around one hour) and I remove the battery too and then I reassembly all and start the system, it starts and I have no reboot, but with black screen. When I turn it off and then turn it on again, the bootloop starts again!

                    I've already tried to rewrite it, but unfortunately it doesn't work.

                    BTW, I took the BIOS ROM from AsRock official page (the .cap file).

                      Motherboard not booting up Issue - ASRock IMB-150
                      by Dergal T Stonkerson
                      I have an ASRock motherboard (IMB-150) with Mini-Sata Solid State Drive. I have removed the SSD card and re-inserted. After re-inserting the device will not boot up. During boot up error displayed "Reboot and select proper boot device or insert boot media in selected boot device and press any key".

                      Connections on motherboard and ssd card look in good condition, no signs of wear or damaged connections.

                      During boot up I pressed F2 to select UEFI setup menu and mSATA 3IE is listed as boot device with no other option available.

                      Anyone have some advice...

                      MacBook Air A2337 (820-02016) USB-C Port Issue – Only Works in One Orientation (CC Line Problem?)
                      by rounin
                      Hi everyone,

                      I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck β€” hoping someone here can shed some light.

                      πŸ›  Original Issue
                      The machine initially wouldn't negotiate 20V over USB-C β€” stuck at 5V.
                      Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.

                      I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.

                      ⚠️ New Problem: One USB-C Port Only Works in One Orientation...

                      Three 820-01700 32GB Logic Boards Same Issue: Won't Wake From Hibernate
                      by ugamazing
                      I have three identical-spec 820-01700 boards (2.6/32/512), and ALL THREE boards came to us with the same fault, from different sources: The boards don't wake from hibernation with the keyboard or lid, they ONLY wake when you press the power button. I understand this is a very minor issue, but the boards must be fixed!

                      We will of course begin with the obvious (checking lid signals), but I couldn't help but notice these three boards were all 32GB variants. Has anyone noticed an issue relating to these 32GB boards in particular? I of course don't think it's a RAM issue, but it's bizarre...

                      Hello guys!
                      I have a strange issue with my laptop keyboard and I'm lost trying to detect what's wrong - the KB9028Q-C or the keyboard itself.
                      It powers on OK and has no other issues except the following:
                      • CAPS LOCK does not work at all
                      • Fn button toggles Flight Mode
                      • When I press 't' or '5', it produces 't5', and when I press 'y' or '6', it produces 'y6'
                      • (with SHIFT pressed: 't%' and 'y^' respectively)
                      I initially thought it was a keyboard malfunction (internal short, etc.),
                      but when I press and hold...
