Laptop has overheating and freezing issues (and when frozen you can hear the fan cranking in overdrive). When putting the lid down for the night, when I come back it will be hot to the touch. Sometimes the login screen is locked (frozen - I can't enter my password, the mouse doesn't work, I have to do a hard reset: Holding down the power button). This was happening more often when it was first installed, but I disabled hardware acceleration in both Firefox and Chrome, which did lessen the problem, but it wasn't a fix as I probably have to do one hard reset daily at this time.
I did change the battery back when it still had OSX installed, but I never had overheating problems with that OS. Looking through the forum, I've seen others include the following info for similar issues.

The highest temps before reset were reaching around 91 deg C. When 19.2 locks up, if I don't hard reset, it keeps spinning and heating up until I do.
