My Laptop doesn't turn after windows 10 reset

I have a G50-70 modelname 20351 .

When I try to turn it on I can see a kind of a glare on the screen, but it won’t turn on.

the battery is charging just fine as it is new.

before this, Microsoft TechSupport did a Windows 10 Reset since I was having issues with the CPU always throteling at 100% due to a System Interrupt process, the reset didn’t solved the system interrupt and after a week I I was using it fine, but then I tryed to turn it on but nothing… it looks like a CPU fail.

I used this PC only for drawing in Fusion360, Photoshop and Illustrator, and some Gaming on Steam.

Is there any way to revive it? how can I know the reason of failure?

Hi @rickybiker,

What indicator lights if any are showing on the laptop when you try to turn on the laptop?

Can you get into BIOS on startup by pressing the Novo key?

If you can get into BIOS and it shows that the HDD is being detected (Information or Configuration tab) try starting the laptop in safe mode - Method 2 and check if it turns on and stays on.

If it does try repairing the startup by going to Troubleshoot > Advanced > Startup repair and follow the prompts.

If you can’t get into BIOS etc try a power refresh and check if that resolves the problem. Turn off the laptop if on and then disconnect the charger if connected. Remove the battery from the laptop and press and hold the laptop’s Power button for 30 seconds and then release. Reinstall the battery, reconnect the charger and try to turn on the laptop.

Only the one on the charging port.

@rickybiker ,

Might be a CPU but could also be a motherboard problem as POST might not even be started.

I don't know if this is any good as I didn't try to download it but you may have to get down to board level and do some testing.

It might be unwise to assume the CPU is faulty and replace it (if possible) only to find that it is the motherboard or worse that it is the motherboard and it damages the replacement CPU.

Thnk you, I'll give it a try , I do have an old microscope Cam and some electronics tools.... but my knowledge is basic... I hope is something easely fixable.

Do you know where I can find a new motherboard (the one with CPU i7 and the Radeon 2GB GPU... just in case I can't fix it.
