I've had this macbook for 30 months, it's a 2009 macbook 13 in' silver and since the software update 10.6.7 and after updating to lion, i've had problems where even when the Mac is closed, the apple light on the back of the screen will flash intermittently once every 20 seconds. For some reason it won't go into sleep mode properly and eats up battery like no other. on top of that, every time I open it after an hour of it being closed, I check iStat pro and see that its 190 degrees F while the fan is only running at 2000 rpm. after I keep it on for a minute it cools down and the fan kicks in but as soon as I open it it gets too hot to touch! I mean on the point of burning my fingers hot! Any ideas here? I've tried pulling the battery already and it's still at 95% health so is this a software issue?
