MBP'10 Display Goes Black and Heats Up When Closed
Hello,
I'm running a 2010 MBP running 10.10.2. Within the past couple months I have been having issues with the display randomly going black, as if it were sleeping, but the indicator light on the front is off and the computer is unable to be used unless I force shut it down and turn it back on. Also, when the clamshell is closed it will randomly begin heating up and get super hot. Both of these problems have been getting progressively worse and just yesterday I had to force shut it down multiple times and felt it heat up when closed. I replaced the battery because of cycle count, thinking it would fix it, but it continues to happen. I tried to reset the SMC, but when I hold Shift+Control+Option+Power for 5 seconds, it just boots up and I see no light change on the power cord.
Is this likely a software issue or a hardware issue?
Thank You,
MacBook Pro (13-inch Mid 2010), OS X Yosemite (10.10.2)
