Last night I noticed issues with charging my laptop while I was using it. THe charge shut off randomly, and the metal part of the port that connects to the computer seemed unusually hot. So I unplugged it, let it sit, and plugged it back in with little issue. Today I went to plug it in and the charger didn't work. I went to use my friends charger and his works perfectly(using it now) and mine didn't work on his so it seems like it's the charger. However, up at the battery details on the top right of the desktop it says "service battery". It's charging fine with the different charger, but I'm still wondering why this is up. Can anyone clarify that it's just the charger? Also, where is the best place to buy a new one?
