    ASUS P8B WS fire on power up

    This is my first post so please be kind. New ASUS P8B WS mb. Since it will be a pretty basic system I just put it in the case and made all of the connections and turned on the power. Pop, a little tongue of flame, and a puff of smoke from one of the tiny caps on the bottom left of the board. Immediately shut down the power. I'm not sure it will run like this, but didn't want to make anything worse. Is this a common occurance? I've built ant least 25 systems and this is my first problem of the type. The mb is now in the RMA process. Please, thoughts from anybody.

    Are you sure all the motherboard standoffs were in the correct positions in the case. If not, you may have shorted the board out from underneath.
    Ludicrous gibs!

      My mb came with the standouts preinstalled for an ATX and when I put the mb in the case the matchup was perfect. The best I have ever seen.

        Photos please....

        No, don't run it like that.

        Were there 'extra' standoffs in the case?

        Sounds like offending cap was installed backwards.
        That would be a manufacturing defect and you should have it replaced by warranty.

          Sorry, no photos. Already shipped to supplier. I didn't even think about running it. No 'extra' standoffs. Exactly 9 in the right spots for an ATX. Apparently the mfgs checkout does NOT include a power on test.

            Was it a brand new case?
            Last time I saw this happen, the customer had mangled the front USB port.
            The PC wasn't turning on, we were fiddling with it on the workbench (unaware of the USB port) and saw the fuse burn up.
            Unplugged the front USB ports and away it went.

              Good thought... with front USB ports, there would be a fuse in that general location.

                Brand new case, top of the line Lian Li. It was carefully assembled and nothing was mangled. The steps when I turned it on were as follows: set the swith on the power supply to "Off". plug in both ends of the power cord. turn the switch on the ps to "On". (It comes up in the deep sleep state.) The mb has has two switchs, On/Off and Reset, on a G.P. Maintenance board. These two switchs function the same as the external switch. I used the On/Off on the board. (at bottom center) The flame and smoke were from a tiny cap about 2 inches to the left.

                  Hmm. Don't know then. Good luck with the replacement

                    Asus Probook P5440UF-XB74 power issue
                    by GLISIT
                    Hi all,

                    TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!


                    I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!

                    A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about...

                    Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                    by Tynan Dill
                    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...

                    Microsoft Surface Pro (5th gen) model 1796 - no power
                    by PantherDave
                    Hi all!

                    I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅

                    I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

                    ASUS TUF X570-PLUS doesn't power on: no VRM_EN signal.
                    by ShadowAi
                    Hello, I have an issue with the motherboard. Specifically, it doesn't power on, more precisely, the POST initialization doesn't occur.

                    Let me start from the beginning, the motherboard suddenly stopped working one day. There are no beep signals from the speaker, and the debug LEDs are not lighting up. After inspecting it under a microscope and using thermal imaging, I didn't find anything that could be damaged.

                    After that, I began voltage measurements, in which I noticed the absence of VDDQ, VDDP, VTT, and VPP lines. Later, I checked if there is an EN state on these lines,...

                    Hello, I have an asus Z97-A motherboard and it doesn't start which was working properly before, the problem isn't related by ram, ram slots or psu (I changed all and nothing work), the exact problem is when you switch it on , it starts and after 1 seconds (no boot or display picture) it's off and then on cycle continuously until you power it off from psu also it's responding to the power switch for turning it off if you keep pressing it 3 or 4 seconds (power button pin has 3.3v) , also when you start it with eatx 12v socket connected this is happening (power cycle also all voltages are resetting...
