    Always turn the power supply switch off

    On my shop box the shitty case (but one I have to use because it has two easy to insertable physical sata bays on top) for 2.5 and 3.5

    The USB 3.0 case on top is a literal USB extension cable to a 3.0 port on the back (was made many years ago)

    So I got a 5.25 front panel with 4x USB 3.0 ports because the motherboard has 2x 3.0 headers (four ports total). Soo I tried to plug them in and it didn't go. It bent some pins. I was straightening them out with a dental pick when suddenly the computer turned on when I shorted two of the pins. Didn't think much of it and switched the power off

    I took a sewing needle and made the holes on the plugs bigger, it then fit in after

    Aaaand suddenly none of the ports worked after I turned it on. Must have been a power to data short.

    Luckily it has an ASMedia chip for the USB-C and one USB-A 3.0 ports. I was able to get into windows and The USB xhci driver in windows said code 10, failed. Can't get into bios without hooking it to the Asmedia 3.0 port.

    Soooo now I'm going to have to get a PCI-E card with headers and ports (perhaps two) and possibly a hub for the USB-C in the back. God damn that little $17 panel cost me big. But it is my fault. I rarely ever have a non-power header short that causes a turn on. This is actually the second time I've ever had a non power header short turn it on, but the other one was putting a PCI card in and it didn't damage anything

      Re: Always turn the power supply switch off

      Funny thing you mention this… had something similar, but on mine the USB was intermittent. So I went and try bending the pins and no go. So I proceeded to change the USB port since the tabs on the sides were broken and the metal casing of the port bent. That was a couple of days ago.

      Look at the main board and see if there is a fuse or something? I had a fuse on the board.

        lol
        in future configure the motherboard to NOT wake on lan,usb,keyboard or any other "event" other than the power button.
        also, if it has a jumper for it, you DONT want usb powered in standby!

        i'v had boards jump to life by accident because of those stupid options - you have to be pretty fucking lazy to need to turn your pc on by touching the keyboard!!!

          WoL is good, saves me a trip to the basement to power up machines to get them to run backups...

          It's a matter of knowing when to turn the switch off or unplugging. Generally if you don't know what you're doing, unplug!

            Probably several, I doubt I can find the main USB one because none of the ports work

            also with the Code 10, I think it's permanent damage

              usb signaling is 3.3v so look for some tiny zener diodes on the data lines

                At least you didn't swap a motherboard with the power on.

                  i saw a guy power up a motherboard while it was sitting on the coated-mylar bag once - he thought it was an insulator till it sparked and killed his board! LOL

                    Never use an antistatic bag as a insulator, especially for testing.

                      Wait, do you mean the grey anti-static bags are conductive?

                        of course - how do you think they disipate static?
                        it's a thin coating of metal.

                          Oh shit. I mean, I've soldered that was on a big static bag, and a few times I've booted boards on a bag. Though without any problems. Hmm, perhaps its not totally conductive

                              then it's not anti-static
                              it should read in the megohms

                                oh fuck me. Now it won't reset or power off. Always have to keep the power button down or turn the PSU off.

                                          by sam_sam_sam
                                          I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

                                          One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

                                          Got this one for free because, well, it no worky.

                                          A little research and there are tons of complaints all over forums/the internet about premature failure of these switches. The observation everyone makes about these is "they run hot" and failure occurring as soon as 13 months, right out of warranty, of course.

                                          Upon removal of the cover I found a G0398-15011480A power supply that, when plugged in, was making a constant ticking noise. Multimeter confirmed the PSU was the issue. Output was cycling between 0 and about 20V. With output disconnected it sat around...

                                          I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                                          Upon bringing it home and plugging it up, it showed a standby light.

                                          I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                                          The screen seems to blackout and stay black, but with a flashlight I can see the display.

                                          With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                                          Assuming...

                                          Micro Momentary Push Switch?

                                          Great to be here! I'm a newbie here trying to find a "micro", momentary push switch to repair a Sony "clamshell" video walkman. This micro switch has long since discontinued by Sony, however I hope there are third-party switches of the same size and functionality that I might be able to source to play the same role. The purpose of this switch is to tell the video walkman that the user has activated the mechanical tape eject button, turning that physical action into an electronic signal that tells the tape transport mechanism to open so one can load or eject a video tape. I...
