    Soyo Dragon Cannot Restart After Shutdown

    Hi, I have been question which might or might not be related to capacitors (cause I didn't find any bad ones). The issue I am having with my Soyo Plus Dragon 2 motherboard is that once I do a shutdown it won't start up. After some investigation I realized that the red standby LED on the motherboard does not come up after shutdown. I beleive ATX PSU always give the 5V supply. I tested this with a different new power supply and received same symptom. The only way to restart is to plug the power cable out, wait for 10 seconds and then start the computer.

    Any ideas ?

    If you don't mind some more disassembly, I suggest stripping system bare and try it. If power is normal, start your reconnects. You may find a bad component.

      some nics iirc run from +5stby as well as the keyboard/mouse.
      thats for wake on lan/power on by kb/mouse.
      you might want to try a different better psu in case +5stby is being overloaded.

        A few questions:

        - Has the motherboard always behaved in this manner or is this a new development?

        - What PSUs have you tested it with?

        - Have you tried clearing the CMOS, or failing that, flashing the BIOS with the manufacturer's latest version? I've seen BIOS flashes cure all manner of bizarre "hardware" problems.

        Let us know.

          The motherboard was fine for maybe a year. it suddently started behaving like this .. I have already tried using a new PSU (450W I don't know the model). There is nothing else besides an AGP video card. I will see if there is any newer BIOS and also try with a different video card.

          If nothing works then I might just have to put a sticker "Please turn off the machine from the power strip after shutdown" :-)

            I have this exact motherboard with this exact symptom. It *is* bad caps. The 3300uF 6.3v Sacon caps surrounding the processor have all failed - but only one is bulging slightly on top. Some of the Sacons will fail silently and not show any visible signs of leaking. I'm in the process of recapping this board with Nichicon HE's/Rubycon MBZ and I will update once it is completed.

              Asus PU551LA cannot restart after shutdown
              by Caimano
              Motherboard PU551LA Ver 2 with Intel i5 4210U
              I bought the motherboard as faulty to replace a similar one not repairable because it was completely shorted.
              3V EC was shorted to ground because of EC chip. IT8585E FXA replaced with IT8585E FXS. Motherboard now works and I am able to recharge the battery, install Windows and update BIOS from Ver 207 to 210 with EZ Flash, but it has the following problem: Every time I power off the laptop with power switch or with Windows shutdown the laptop apparently turns off, but the power LED remains on and it's not possible to restart the laptop....

              Dell G3 17 3779 Weird power cycling and shutdown/restart issue
              by SuperJames
              This one's a weird one, and still unsolved despite it having gone back to Dell once.

              Specs

              i7-8750H, GTX 1060 Max Q, 500GB SSD & Seagate 7mm 1TB HDD. 17.3 IPS screen. This has the fingerprint reader in the power button.

              Backstory

              I bought this from eBay, from a wallpapering shop. £650 in 2020 which was a good price considering it's a gaming laptop. Physically it's in perfect shape, apart from the hinge mounts on the palmrest failing in the time I've had it (I have a new palmrest for it). The usual thin plastic crap modern build quality!...
