    When I close the lid of my laptop it goes to sleep the logo turns off and so does the screen. But every minutes or so it start flickering for no reason.

    What can I do?

    I've also noticed this. When my lid is closed the apple logo flickers every minute or so. This happens directly after a relatively discreet sound from the superdrive. Why is this happening? Do you guys have the same problem, or is it a problem?

    This happens both when I'm connected with the magsafe adapter and while running on battery, and I'm concerned about battery drain, since the computer probably wakes up from sleep when this happens...

    Im still experiencing this problem.. I now know you can set your laptop to wake from sleep when it detect bluetooth and firewire but they're both uncheck so I dont think thats the cause of my issue, what about you?

    Is there anything else that can wake my macbook like that?

    This seems to be a problem with the magnet diode or something like that, try this solution:

    "Disable waking up from sleep mode when lid opens:
    Terminal (Applications > Utilties)
    OFF: sudo pmset -a lidwake 0
    ON : sudo pmset -a lidwake 1"

    People are saying that this issue is USB-related, for example wireless mice and keyboards can wake your computer up from sleep. Anyway, the problem has occured when I didn't have ANYTHING connected to my macbook, so I'm not sure about that.

    The solution I posted earlier should be working, the only difference is that you'll have to press a key or something to wake your computer up after you've opened the lid.

    EDIT: My problem seems to be gone after using the command: sudo pmset -a lidwake 0
    I used it once, and it solwed the issue. Then I changed it back, and the issue hasn't returned, at least not yet!

    What i heard as well, ive experienced this problem as well and from my memory it could well be tied to the times ive had my usb mouse plugged in or plugged out just before i put it to sleep.
    Havent had the problem in a while where i havent used any usb

    As a troubleshooting measure, can you disable the wake from sleep when opened feature? If you do so, does the issue still occur?
