After a year and a half, my T4215 has been having a couple problems. First, the bottom left side (by the fan) gets super hot, unbearable to put on my legs. Second, the battery lifespan is getting super short. And last, sometimes when the computer gets super hot the fan starts clicking. Unfortunately my warranty is up, so I can't really just send it off to them and have them fix it. I am wondering if any of you guys know what the best way to fix this would be? Thanks in advance.
