P157SM Motherboard dead

Hi All,

I'm at the point of giving up and going over to Mac right about now. I bought my P157SM back in June 2013. About 3 or 4 months ago, playing Borderlands, the motherboard fried itself, and I had to get the laptop repaired.

Just today, playing Don't Starve, the thing went ahead and died again! The fans were at their lowest, the laptop was running at a pretty comfortable heat, then bam it shuts off completely. Pressing the power button, lights flash on for a second before cutting off. Front lights indicate when the charger is plugged in.

I'm now wondering if there's something I'm doing wrong, the repairer did wrong, or if there is some hardware fault that only I seem to be facing.

My specs are below, in case there's an incompatibility somehow.

Screen type: 15.6" FHD 1920x1080 LED/LCD 95% Gamut Matte
Graphics: NVIDIA GeForce GTX 765M 2GB GDDR5 graphics
Processor: i7-4700MQ Quad Core CPU 2.4GHz up to 3.4GHz
RAM memory: 8GB DDR3 1600Mhz RAM (1 x 8GB memory)
Primary drive: 120GB SSD Samsung 840 - 530/130MBs

EDIT: Oh and although there's only 1 stick of RAM, I've tried other slots. The solution from the repair shop was a replacement motherboard last time

 

Was it plugged into the same wall outlet/ac brick as last time?

 

@Meaker Yes it was. never had issues with any other devices using the same outlet though

 

Do you happen to have another stick of RAM you can pull from another notebook to try?

 

So it is connected directly to the wall, though? I ask because they have no surge protection. Even if you don't have a sudden loss of power, the electrical current can spike or sag enough that it's detrimental to the brick and/or the laptop as long as it's connected. A surge suppressor has circuitry to help regulate things and fight against this.

I'm not certain that's what you experienced here, but it's possible.

 

Yes I would get a protected power strip as a precaution.

 

Yeah that sounds like voltage damage. The same kind of which killed my D900F, and my desktop.

Haswell boards are very frail in terms of voltage tolerance. My old HP Scraptop with an AMD turion has no issues in the wall, but my P370SM3 will begin shutting down on its own and the power button will stop working and stuff and all kinds of crap. Same socket. Same time.

Just because one device works doesn't mean others must work. I suggest using an APC Line-R 1200va line conditioner for voltage problems. And if you DO have frequent voltage issues (which the Line-R will show) then you should check your wiring and with your power company.

 

where did you buy?
