More tinkering with laptops. This time, my brother’s Dell XPS laptop was acting up. I had to clean up a lot of gunk and dust, and apply some thermal paste to the CPU and GPU for better temperatures on the processors. Dell’s automated process applied waaayyyy too much paste, which apparently is a common issue with their product line. Everything seems to be working well. Now all we have to do is see whether the thermal paste reapplication helped.
