Hi all, My MacBook Pro has been running since 2010 for about 4 years. Recently, the battery has gotten significantly weaker (it discharges a full charge in about 2 hours), and heats up very quickly. The heating up is worst during charging, but it can get very bad just running simple apps such as Safari. Furthermore, when I charge the mac, it sometimes feels like there is a faint electric current running along the unibody.
Try cleaning the dust out of the machine. Open the laptop and do a complete cleaning. clean out around the fan and battery area this will help with the fan cleaning MacBook Pro 13" Unibody Mid 2010 Fan Replacement Hope this helps
