Solved! Laptop automatically disconnect battery and turns off while gaming??

[howercho]

Hello beautiful and knowledgeable people. Please save my laptop

SO i've had an MSI gt70 2PC Dominator for almost 4 years now. It has worked perfectly until about 2 weeks ago when something started happening.
While gaming and ONLY while gaming after random periods of time my laptop shuts off by itself. The battery disconnects for a brief moment and after that it shuts down.
It only happens while gaming and never while doing anything else.
I've run stress tests on the CPU,GPU and RAM and everything seemed to be alright.
The battery has kinda been dead for a while now. What i mean by that is it can only last about 5-10 minutes if unplugged and that's it. However the problem occurs WHILE it's plugged in and at different battery %.
I don't know if this is related or not but my battery indicator seems to absolutely ALWAYS say "plugged in not charging."

I've ran SpeedFan to look at my temperatures and unfortunately i dont have the knowledge to know if they are high or not for a laptop but the hottest part is always the CPU at around ~80-85C While gaming.

I've made sure i've got all of my drivers up to date as well just in case.

What could be the cause of this problem ?

Thanks to anyone who tries to help in advance.

for overheating laptop have a protective chip when CPU is getting too hot that chip - mosfet will cut the power off .
