    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...

    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. πŸ˜…

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

    Dell 7280 Power Issues (LA-E122P)
    by reid
    Hi, this is my first new thread and I am hoping to get some assistance troubleshooting a Dell Latitude 7280 (LA-E122P). I have fixed a few MacBook logic boards before, but I'm not familiar with Dell boards or schematics, so I don't really know what things are important to know or check first.

    When I first got the laptop, it would not turn on. I'd plug it in and press the power button, the power LED would come on for a second and then turn off and the laptop wouldn't do anything. This was fixed by flashing the UC5 EEPROM, so I don't think there was any hardware issues when I first...

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

    This is my first post! πŸš€
    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 7490β€”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 XPS 15 7590 - Part 2 - USB power issues
    by coputerdiscount
    So back on my first post I had a water damaged Dell XPS 7590 which I was able to repair:
    Dell XPS 15 7590 - Powers via USB-C but not AC (missing PS_ID?) - Badcaps

    Which leans me into a new problem I wanted to start a new thread with.

    This machine now has issues powering or taking power (usb-c/lightning) via its USB ports.

    Symptoms: When a dock is attached, it tends to short out devices attached and does not function, when using a USB A port elsewhere on the laptop, they notify windows of a surge and tend to power cycle the attached device.
