    Every now and then, even after I shut the lid, the fan will remain running for a minute, sometimes longer. Is this normal? I only started experiencing this with El Capitan. Laptop is a mid-2010 13" MBP.

    Thanks for the response/suggestion. I completely missed seeing this until now. I will give it a shot. It sounds like that may well be the problem, especially since I'm experiencing many other symptoms like extended bouncing of icons when starting up apps.

    I just tried this. It did not make any difference. Fan still runs for a while even after the lid is closed. The bouncing icons part is significantly improved. Where it would bounce for a minute for some apps (like skype), it now bounces about 6-8 times (< 10 sec).

    Is the fan running because the machine's thermal paste is no longer effective? Or there is dust in the machine?

    The fan can run till it's sleeping.
    Check the sleep light - eg for my MBP 2009 it'll take a minute to get to sleep. I'm guessing it's getting my 8GB RAM to SSD disc.

    I have 4 GB RAM. How long do you think it would take to actually get to sleep? Mine can sometimes run for a few minutes after the lid has been shut, depending on vigorously it was working prior.

    It can also be cooling components down.

    I went through this last month with my wife's '11 one night it ran all night :eek:

    I reset the SMC got not love so I turned it off, unplugged it, took the bottom case off, disconnected the battery for about 10 minutes buttoned it back up and she's not had a problem since.
