Q: wake up from sleep

My Macbook Pro wakes up by itself, after went into sleep (or close the lid). It drains the battery and generates a lot of heat.

MacBook Pro with Retina display, OS X Mavericks (10.9.3)

Hi yuwen_wang,

As this is a power related issue, I would suggest that you start by resetting the System Management Controller, as described in this article -

Thanks for using Apple Support Communities.

Best,

If you haven't already, you might try looking at Energy Saver in System Preferences. Select 'Power Adapter.' Look for the option to turn off "Wake for network access."
When I did that on my older MBP, I got the helpful explanation: "When 'Wake for network access' is enabled, you may hear your computer wake up occasionally."
That option may get switched 'on' when updating OSX, iTunes, or iCloud.
