Dell XPS 15 7590 – black screen, fans at full speed, no Dell logo
My XPS 15 7590 started having problems about 4–5 days ago. At first it would randomly shut down/restart and sometimes show BIOS corruption, Manufacturing Mode, missing Service Tag and different amber/white LED codes.
During these days I tried BIOS update/reset, reseating/swapping RAM, reseating SSD, different battery/without battery, Windows reinstall and Dell diagnostics (no errors).
For the last 2 days it has become much worse. Now when I turn it on:
● Screen stays completely black
● No Dell logo/BIOS appears
● Keyboard lights come on
● Caps Lock light comes on
● Fans run extremely fast and loud at maximum speed
● External monitor also gets no HDMI signal
Dell support suspects a motherboard failure.
Has anyone experienced this with an XPS 15 7590? Does this sound like a dead motherboard, or could another component cause these symptoms?
