    ASUS zenbook um425 spinning fan only, no power

    i bought it that has a problem that a previous user said it can't turn on after bios update.

    i checked it. If i plug in the power, it just spinning fan. power button didn't work. and then plugged out it, a few seconds later, stop to spin.

    so i detatched rom chip and dump it bios file that get this site.

    sadly, same problem.

    But now, if i plug out the power, stop to spin immediately. so i checked battery voltage. it was 0V (15.48v is original volt, i think, there was some problem last night). and if i plug in power, charging volt is 12.25v ... there is something problem.

              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,...
