    Asus GL753VE - No video/POST

    I am looking at an Asus GL753VE laptop that will not turn on (confirmed defective motherboard). The charge light stays on while plugged into power adapter. Laptop power light comes on with press of power button... stays on until when/if power button is held down for 10 seconds. No other signs of life.

    I do not have a schematic for this board.
    I have not found any visible signs of damage... water/liquid, heat, or otherwise.
    There are 19v, ~5.5v, and ~3.3v at many various places in the board.
    The chipset warms up a little when the laptop is powered up.

    Can anybody offer any insight as to what I can look for next?

    Mb number? Check the voltage on all big gray coils as you power up take a pic mark the voltages and post

      I will follow though with your request when I get a chance... possibly later this evening. But in the meantime, I did realize today that I don't believe the first mosfet (after the power input) is getting turned on.

          Earlier when I said there was "no visible damage"... well please strike that from the record. I found this burned area today. It's directly on the other side of the board from the right hand side of this LCD connector.

            The burnt component is an inductance , remove it and check if there is a short
            on both pads. I don't know where is connected because the nets are under the
            lcd connector.

              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...

              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,...
