I'm so glad I found this thread - I got my EVOC P650RS-G from HIDEvolution back in October 2016 and used it for a lot of gaming back in the day, and very recently it started giving me all sorts of trouble with the system restarting every time I plugged in the power cable. When I ordered it about 8-9 years ago, I made sure I asked for the OS recovery installation USB drive, which I finally got to use today. I juuuust installed a fresh copy of Windows 10 Pro and got done installing most of the commonly used applications and drivers. I'm currently looking for the keyboard backlight drivers, hopefully I'll be able to find those somewhere as well. I have repasted my CPU and GPU several times using Thermal Grizzly Kryonaut, and this machine runs like a champ. My current use case is merely browsing the internet, coding, and reading documents so I'm hoping this lasts me some more time until I need to shell out money on a new laptop.
