After 4 months one day it continually restarts and work for couple of hrs. the next day when I ON no display, keyboard lights on and the off-power button only ON
I take to the service center they took almost 16 days & finally told need to replace your motherboard
[ Half of the price is Motherboard & It is not available in my country (Sri Lanka) but available in online very few of them, I show on eBay]
I wanted to know that do I have to change the motherboard, or it is possible to repair the motherboard

Can anyone mark in the picture where is the problem (Hardware which part need to replace)

If the display is not functioning how or where did the Test results get done.

My guess first thing I would check is the motherboards battery " coin size" in the black plastic that is to the left of the system battery where the battery says "Dell".

I would after that IF the battery " coin size " needs replacing get that done than go into bios and set to defaults.

The GPU failure is weird as that's part of your CPU that leads me to check the coin size battery 3.V when new.

It could be a driver issue but I would see where you get with a new battery.

The Adata hard drive might or might be a real issue, again after a new coin size battery is installed and bios is set to correct settings will only tell.

I would also remove the Adata M.2 Hard drive and reinstall to clean off contacts at the very least.

Question does it even semi function after it came back from repair shop. ?
