    clevo w650sj no power

    Hello,
    I have a laptop with clevo w650sj motherboard and no power,no lights nothing.
    When I connect it with my bench power it seems that it draws 0,7A for a moment and then goes to 0 A.
    I have 19V in PQ 33 and PQ 8 mosfet in all pins except pin 5 on both mosfet which give me 2,5V
    I try to reset the bios, still the same problem. In all electrolytic capacitors (6,3V 2,5V) I have no voltage.
    What else can I check?

      Check VDD3(3.3v) and VDD5(5v). Check for short circuit on all the coils (use diode mode on multimeter put one prob on ground and second on coil 0.00 means short).

          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.

          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 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...

          Asus Tuf gaming fx506l no power, mosfet does not open
          by Thomas Smith
          Hello everyone, I have an ASUS FX506LI laptop that does not turn on, and I need help diagnosing the issue. Here is what I have checked so far:
          Initial Symptoms:
          • The laptop has no power at all (no LEDs, no fan spin).
          • No 3.3V or 5V present on the board.
          • The power button (NBSWON#) reacts but only changes from 0V to 0.5-0.11V.
          Power Rail Checks:
          1. Charger input (FETs PKCH2BB)
            • Drain: 20V, Source: 0V, Gate: 0V (FETs not switching).
          2. BQ24780S Charger IC:
            • VCC and ACDET are present.
            • ACN / ACP, ACDRV, BATDRV, LODRV, HIDRV, ACOK, SRN, SRP – all 0V.
            • Shunt resistor has 10Ω to ground.

          Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
          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...
