[SOLVED] Laptop shuts down when under load

[Conquest90]

My laptop is HP Pavillion dv6-6b56er (core i7-2670qm, Radeon 6700m, 6g RAM, Windows 10). I've had it for some time. Battery stopped working on it long time ago, I've been using it as is. After my house had a power surge I had to replace charging cable, managed to find one with exact same parameters. But after that when I launch high load software (like games) it can shut off compeletely. I took it to repair and they said the issue might be overheating, so they cleaned it. But still after that the problem continues. I managed to create a power plan that keeps it in working order, but it significantly cuts off performance and laptop still randomly shuts off during Windows updates. Looking for suggestions for what the problem might be, what should I look for or where should I point the repairmen towards next time I take it in.

^^^^I suspect even though it said it had the same parameters...it may not ACTUALLY have had the same parameters.

I would try a charger with a higher current rating (same voltage rating) if I could find one.

What parameter should be higher exactly? I don't know much about these things.
The one I'm using right now is 19.5 V 3.33 A 65 W

Either the 3.33A or the 65W.
The 19.5V should always remain 19.5V no matter what charger you get,

The way it works is....19.5X3.33=65

Ok, got it. One more thing though. Is it possible that during power surge not only the charger got damaged but the laptop as well. And if so how do you tell? Would be a waste of money to buy a more powerful charger and not having fixed the problem.
