Hi Sifus.
My MSI GT72 2QD have an issue of sudden full shutdown whenever I run games. It's like fully no power at all. I have to switch off power from the wall socket and turn it back on, in order to be able to restart the laptop.

Some details:
1. the shutdown can happen anytime between 2mins to 5mins of running games, with or without being plugged to power.
2. Temp for GPU when this happens is below 65C. CPU is about 50C.
3. If I'm not running games, the laptop behaves normally.
4. I tried using heavenmark, which also causes the shutdown issue.

I have attached the MSI Afterburner log. Not sure if you can point me to some clues for a fix. The laptop is out of warranty, and MSI official support requires about 2-3 days to diagnose and up to 14 days to order parts, which is a bummer. Hope you can point me to the right direction.

Total power off. Can't start unless I unplug the power cord from the wall socket and then plug it back in.

Thanks a lot for the quick replies, guys.

If it's VRM issue, does that mean changing the graphics card will help?

Thanks for helping. Here are the details:

Wow. You're right! Seems to be ok so far after disconnecting the battery.

Quick update. Shutdowns still happening but at longer intervals after disconnecting battery. Looking at 20 to 30 mins.

Thanks for the tip. Will check on this tomorrow and update. Out of curiosity, if power brick is the issue, won't the laptop run on battery first before powering off? My experience is that it'll run on battery for about 10 secs before powering off completely. Battery is still above 90 percent at all times. And it's a new battery.

Tried on a different power brick at an MSI shop. Same problem. I guess this is a motherboard issue already. Oh well.

Just mentioned potentially motherboard. Need more time to diagnose. But I'm uncomfortable to leave my laptop overnight. Probably gonna repurpose it to non gaming laptop.

Hi there! No. Support for MSI is pretty poor. They have to inspect, then request for parts from overseas. Whole process will take weeks.

I've since switched to HP gaming laptop.

HP Inspiron 15 7000. At least they promise premium customer service.

My MSI currently I'm using for basic use. The mobo seems to be ok as long as I'm not running games. I think just a matter of time before it goes kaput for good.

No. I did not. That's too technical for an uncle like me. All I've tried is change the battery and manually clean the fans and remove and stick back heat sinks with new compound.

And it's already not under warranty.

Wow. Good luck! Hope things will work out.
