Acer Predator Helios 300 PH315-51 — No Display / No Boot Issue Keeps Returning (Tried All Fixes, Sti

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.

    Hi, this 2018 laptop may not run properly with Windows11 OS, the last BIOS is from 2019 and only Windows10 drivers are available on Acer Support. Microsoft will install W11 compatible drivers but there may be some update/driver issues, I don't recommend installing W11 version 24H2. Try reinstalling Windows10 22H2 with a USB flash drive or ask Acer Services in your country to install Windows10 OEM for you.

    There was no display issue. How can I install Windows without a screen? It's not booting; nothing shows when I click the power button. The keyboard backlights turn on, and the fans spin briefly before stopping.

    The problem you are having is because either the EC chip or the Chipset chips that control the pre and post boot cpu and imaging to your laptop are faulty, as and if your NVidia gpu is not affected and the laptop works sometimes and has an image, then its not the dedicated gpu but it could be its vram. A new and programmed EC chip is available for your PH315-51 model, but and if its the Chipset, then that could be a problem to get and find for the PH315-51 model or if its a vram, then you can't get that chip either.

    The red marked chips are the EC and Chipset chips fitted to the PH315-51 model, the EC chip is on the left and the Chipset chip is on the right.

    Take you laptop to a specialist technician that can replace the EC chip and program them also or can get this chip and is prepared to search and buy a used Chipset chip for your PH315-51 laptop, as getting a good and workable Chipset chip is a problem as very few of them are for sale. Good luck and hope this gives you another option, otherwise buy a new mainboard as they are not too expensive on eBay or AliExpress.

    These are all the mainboards listed for the PH315-51 laptop model
