    I have a Mid09 13in MBP.

    I noticed that when I put it in sleep, the USB ports still get power. Is there a way to make it so they turn off when it sleeps? I have a cooling plate attached so I have to unplug it every time I sleep it, gets pretty annoying when I forget and I unplug the USB plug and the MBP turns back on. My mouse/keyboard are BT so it wakes it that way, not by USB.

    And is it bad for me to have the laptop running with the lid closed? I don't know if the heat would affect the screen or not. I'm currently not doing this because I'm not sure about the effects of the heat on the screen, but I do use a cooling plate, average temps are 120-130*F.

    Thanks for any positive responses.

    I am not aware of any way to turn off the USB ports when sleeping your Mac.

    You can run your laptop in clamshell mode; it should be fine, especially with the cooling pad.:)

    For example, I'm using the miniDP cable with my TV, BT mouse/keyboard. Would that be clamshell mode? Does it do this automatically when everything is plugged in or do I have to change it somewhere?

    I think having powered USB ports on all the time is by design. It allows you to charge external devices (like iPods) while the laptop is not in use.

    If the screen lid is closed while you're doing this, the machine is in clamshell mode.

    My late 08 unibody MBP has powered USB ports when its sleeping. I thought it was weird.

    I have an aeolus laptop cooler (usb powered) and its fans keep spinning when I put the MBP to sleep. Likewise I notice my bus-powered external drive is still lit up when my MBP is sleeping.
