    Dell G3 15 3500 - Battery bug (black screen and flashing keyboard backlight)
    by HTR-Informatique
    Hello,

    YouTube video of the problem encountered: https://youtube.com/shorts/q7TLNv36LUo

    I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.

    On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.

    I also changed the screen because the PC fell and the screen was broken.

    I changed the battery with a new and original battery.

    I also had corrosion/oxidation on the...

    Hello everyone !

    My name is Chris, I am a 30 years old embedded software developer working in the automotive industry. I am really passionate about learning new skills and repairing/crafting stuff. I came around this forum last week with the goal of repairing my faulty gaming laptop, indeed, I was video editing on it when suddenly a black screen popped and never disappeared I bought some stuff to try to repair it and learn as many things as possible about computer repairs but nothing worked so far. When the black screen appeared, my legion 5 pro was connected to my external monitor...

    Acer Aspire E5-574-52RH - black screen
    by DaniK
    Hi everyone,
    I have this strange behaviour with Acer Aspire E5-574-52RH, i5 6200U, intel graphics, DA0ZRWMB6G0 Rev G, model ZRW.
    Laptop came in for a SSD upgrade, took everything apart to install the SSD.
    Everything started after modifying BIOS settings to boot UEFI instead of Legacy.
    Laptop works fine, i installed windows 10 and drivers/updates, everything works ok(when it works)
    The black screen problem is random, maybe 5 out 10 times, laptop remains with the black screen, no image

    Symptoms are:
    - random black screen after displaying Acer logo...

    Acer K272HUL blue power light but black screen, power supply is ok
    by burntonnerings
    Have had two Acer K272HUL monitors die with the same symptoms:

    - Blue power light is illuminated while the monitor is plugged in
    - Black screen (no splash screen, etc.)
    - Power button doesn't do anything

    Opened it up and checked for bad caps and components, evidence of burns, etc. - everything looks fine.

    Power supply voltages are fine.

    There are some signal lines on the power supply harness that goes from the power supply to the logic board, not sure what these should be at.

    Anyone have any ideas?...
