Laptop Unexpected Shutdown

[FuzuliPanda]

Hello there. My Laptop (ASUS 5755G) has a shutdown problem. Whenever it's plugged in every piece of gaming i do shutsdown the computer BUT if i unplug it i can play those games until the battery runs out. I already ruled out heating on cpu/gpu because the temps are normal but cant find the pattern to shutdown problem. Can anyone help me?

Edit: I should probably add that after shutdowns computer goes into a phase. When i press the power button it powers up for 1-2 sec and shuts it down immediately. It works after 5 mins of waiting.

Edit-2: Can play low demand games like HOMM 3 or can watch movies infinitely but as soon a half demanding game launches the shutdown happens in less than 2-3 mins.

It sounds like the laptop is getting short circuited. Have you checked the voltages when this happens?

How can i check voltages? I've been looking for a program to log my voltages as soon as a short circuit happens but can't find any. Suggestions?

HWmonitor or realtemp.

Do they keep logs where i can check minute by minute?

In hwmonitor you can save the data but I don't know if you can view it minute by minute. Its free so you can download the software yourself and see.
