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.
