Acer Predator Helios 300 PH315-53 doesnt turn on, only keyboard and turbo lights up

👋 Hey @snj2222 ,

Thanks for laying out the symptoms clearly — it really helps. Based on what you’ve shared, this sounds like a deeper power delivery fault or a critical POST failure. Here's a breakdown of what's happening and what you might try next:

🔎 What the symptoms suggest:

• The keyboard and turbo keys lighting up means basic power rail activation is happening.
• Fans spinning briefly and a single beep imply the EC (Embedded Controller) starts POST, but hits a fault — likely with the GPU rail, RAM, or internal power regulation.
• No display and shutdown usually indicate a failed initialization on a required subsystem.

🔋 Could it be a dead battery? Yes — after 4–5 years, battery degradation is common. But it's tricky: some Acer models won’t boot properly with a failed battery even on AC power. Others may need battery presence to initialize EC firmware.

🧪 Steps to try before replacing the motherboard:

1. powercfg /batteryreportThen check the generated battery-report.html in your user folder. It shows battery health trends over time.
2. Try booting on AC only with battery disconnected — but only if you're comfortable opening the chassis safely.
3. Listen for more beep codes or LED blink patterns if available — sometimes there's more to decipher.
4. Try an external monitor, just in case the iGPU/Display panel connection is the issue.

🧰 If you do decide to replace the motherboard:

• This model uses Acer’s proprietary board for the PH315-53 — based on Intel HM470, with DDR4 RAM and a dedicated GPU (usually RTX 2060 or 2070).
• Look for an exact part match — typically labeled near the RAM slots, something like “LA-H981P” or “NB.Q7DAA.001” depending on revision.
• eBay, AliExpress, or trusted repair shops may have refurbished boards. Just confirm the cooling layout and GPU variant match yours.

💡 Small note: A local PC shop might help confirm if this is just a failed power rail (like the CPU Vcore regulator) or a deeper EC fault before you invest in a new board.

Let us know what info you find — even part numbers or battery behavior — and the community can help narrow things down further. 👍

Want me to refine this with more specific part numbers or make it sound like it’s from your usual tone on the channel? We can even drop in a light reminder that motherboard swaps on gaming laptops need heatsink alignment too.
