As of lately my computer has been getting severely hot where the battery is. My macbookpro is a late 2011 model and I am guessing my battery is starting to go bad or possibly the fans malfunctioned. I looked at how many cycles I have on the battery and it was around 600 plus. I did open up my laptop and installed ram, and was going to install a ssd, but I have not had the time yet. Also these problems started to happen after I installed the ram. I'm just wondering if there was a definite way of determine the problem, any suggestions? Also I was having problems with the screen getting lines and apparently RadeonGate was with my particular model, luckily that has not happened in almost two months. I just have a host of problems haha.
