    DELL IPCML-CT rev a00 pOWER ON PROBLEM

    Hi everyone,
    I have a problem with this dell mini desktop, no LED lights up and there is no response from the front power button. It literally feels defunct, with no feedback whatsoever.

    IPCML-CT motherboard rev.A00
    CPU: Intel Celeron G5900T

    I tested the power supply (19.5v correctly) but to be careful I also used an alternative power supply to test, nothing. No LEDs, no power on.

    I tested the power button pins and they correctly measure 3.3V, so when I press the button or put a bridge with a wire, the pulse seems to be there correctly.

    What could be causing the motherboard to not turn on?
    I also tried without RAM, without SSD and without CPU. but without the cpu it wouldn't turn on anyway.

      Dell latitude e7470 not turn on .power buton on off and Run Power problem
      by masoksian
      Hi everyone,

      I am dealing with the problem of turning on and off my Dell e7470 notebook.

      The battery charge light is solid white, I press the button, the power indicator and the light on the button are solid for 1-2 seconds and immediately turn off.

      The system does not turn on, there is no post.

      I removed the RAMs and changed them, changed the battery, RTC battery, AC adapter, removed them and waited, tried again, it does not turn on.
      The problem continues in the same way.
      I tried to turn on the Fn key, nothing came to the screen....

      Dell Optiplex 7490 AIO - red power led after flash
      by Mark01
      Hi guys,

      This is my first post! 🚀
      I have no idea what I’m doing, but I’m learning by trial and error.

      I’m currently working on a Dell Optiplex AIO 7490—one of a bunch of AIOs that mysteriously failed to POST just a few days after the warranty expired. The original issue was that the PC worked fine until it was rebooted, after which it got stuck on a black screen (no backlight), with fans spinning at normal speed and a solid white power LED. Forcing it off by holding the power button would just cause it to switch on automatically and get stuck again on...

      Dell inspiron 17 (7786) - DP/N 09P7JP - odd power issues, starting with no power LED
      by zlr8r
      hey guys, hoping for some pointers to repair an eBay bought "faulty" laptop.

      Ill try and give as much info as I can.

      Dell Inspiron 17 (7786) Laptop
      Service Tag: 5J0NHT2
      Bios: 1.9.0

      When I received this , it would only flicker on the KB backlight for a second, then off and on.
      Then it started getting weirder!
      Sometimes when attaching the AC power supply, and pressing various pre-boot diagnostic keyboard keys... it did try to boot, in fact out of a hundred attempts, the laptop did actually boot into the Bios ! but never has...

      Problem with LG Plasma 60PM6700 - Random power downs
      by theone111
      I have an LG Plasma TV 60PM6700 for the past ~12 years.

      In the last ~3-4 months I have been having some issues.
      1. Problem: It started with random picture disappearing (sound still worked).
        Frequency: Happened about once a week.
        Solution: Had to turn off TV wait a few seconds before turning it on again.
      2. Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
        Frequency: Happened about once a week.
        Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve.
      3. Problem: TV shuts down

      Asus x512dk rev 2.1 power on problem
      by Duranitron
      When I reflash again the bios of hoaca388 the unit powers on and the unit lives!!! Hooray!! All voltage in the coil 3.3v, 5v and 6.7v indicate charging are all present. including the cpu voltage , EEPROM and GPU voltage the unit is now alive, normal screen booting to windows and log in screen until I power it off. Then the unit never goes on even when pressing the power button in the keyboard.. Voltage reading 19v main , 3.3v VCC in IT8225E-128 and EEPROM VCC 0 volt and the charging voltage 0 volt.

      Try to trace the power switch button goin to the power switch IC PU8803 (APL3533AQBI-TRG)...
