Battery and low performance problem
Model nr: G3-572
OS: Windows 10
Serial nr: NHQ2BEH004745094373400
Last Sunday (7/10/18), My pc couldn't get to the bios and kept rebooting, only my key lights turned on and off each reboot. It only stopped after closing it. I needed it for school, the first thing I tried was just unplugging the battery. It does start up, but everything runs a lot slower. Overwatch doesn't get to 60 fps anymore, even on lowest settings and easy tasks (like opening explorer) take a lot of usage from my CPU and load long. I've already tried replugging the battery, which worked until later in the day when I woke it up out of sleep mode, it was the same as the first time. Even though the battery worked perfectly without the charger, the performance was still as low as before.
In the past, I upgraded to 16gb RAM, replaced the SSD with a bigger one, and redid the thermal paste to resolve the heating problem, this was 2 months ago.
