Previously, anytime I would close the lid of the laptop it would put the computer to sleep mode. Now, when I return to my laptop, the computer is warm (sometimes extremely hot with fans on max speed), so obviously it's not going to sleep. Any ideas? I did the pram reset and it didn't do anything. I've seen others here with the same problem but they all seem to be using external monitors - I'm just using the laptop screen. Thanks for any help.
