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

snj2222

I have been using this laptop for 4 years, recently one day it sropped turning on, whenever i try to turn it on, the keyboard and turbo lights up, fans run, the display doesnt turn on and then it tuens off with a single beep.

Based on my findings, i am assuming the mother board is overheated and cooked. I am not quite sure, i want to take it to a pc repair shop, but on the safer side, i want to reach out to this community before to find more answers.

I am planning to replace my motherboard if that can solve the issue , i am unable to find an exact motherboard for laptop, which motherboard i need to go for, if i want to replace it, what the issue might be,

i will be attaching more pictures here which i think might help someone here to figure out which mother board I actually need.

👋 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.

You can take the RAM stick out, clean its contact, and put it into the other slot. Also, try to hold the power button for 15 seconds without the charger plugged in to reset the power.

I did try the battery method thats been mentioned in the comments, removed the battery, plugged in the laptop without a battery, turned it on, IT WORKED, the display is up, the laptop is up and running.

Now, i am assuming battery us the fault, if i replace the battery, will it solve the issue? Or should i still take it to a store and get it checked, and proceed further, i really dont wanna spend more on this laptop right now.

Can I use the laptop now without a battery in it, directly on AC power?

while turning on, the predator booting screen is making a loud noice, more louder than what it generally does, is that a concern i need to worry about ?

I am open to whatever suggestions you guys provide me.

Hi @snj2222 , Glad to hear the laptop booted after removing the battery. Based on your symptoms and the age of the machine, the battery is likely the root cause.

🔋 First step: Replace the battery if it's more than 4 years old — that often solves boot issues like this.

⚠️ If problems continue after replacing the battery, bring the laptop to an Acer Service Center or an authorized repair shop near you. They can check the power rails and confirm if there's a deeper fault with the EC or motherboard.

hi @Puraw i tried turning on laptop after couple of hours again, it is not turning on again, it is running into same issues again, keyboard lights up, and then turns off after a single beep.

I have not put the battery back yet, still runningg on AC. Turned it off, unplugged for a couple of hours, plugged back in, tried to turn off, the display doesnt turn on, it shows the same error, mention in the main post

You can bring it to a shop that specializes in motherboard repair to diagnose.
