Hi ,

I'm facing a recurring and extremely frustrating issue with my Acer Predator Helios 300 PH315-51 (GTX 1060 model). I’ve tried nearly every solution and even involved the official service center, but the problem keeps coming back.

Issue Description:

  • When I press the power button:
    • Keyboard backlight turns on
    • Fan spins for a while, then stops
    • Display remains completely black — no Acer logo, no BIOS, no boot menu
    • Backlight stays on, but nothing is displayed
  • Tried connecting to external monitor — still no display

This happens whether the laptop is on battery or plugged in.

  • Opened the laptop myself:
    • No signs of burn marks, tampering, or repair.
    • tried reseat RAM and SSD

  • Purchased a new main battery and CMOS battery, as the Acer service center suspected they might be the cause.
    • Still faced the exact same issue again after 7–8 days.

Took it to the Acer Service Center TWICE (a 7-hour trip each time).

  • They “did something” and it worked both times for a few days — then same issue returned.
  • They didn’t explain what they actually fixed.

Current Situation:

This issue has now repeated 3 times in less than a month. I’m mentally exhausted and physically unable to keep traveling 7 hours to the service center again and again, only for the issue to return after a few days.

I strongly suspect this may be a BIOS/EC controller bug or a hardware-level fault (GPU/motherboard-related), as I’ve tried replacing the battery, testing with external display, full disassembly, etc.
