    My 15" i5 MacBook Pro won't sleep when charging; a reset of the SMC solves the problem temporarily, but it always recurs. Interestingly, the sleep indicator light pulses as if the machine is sleeping, but I can clearly hear hard drive activity; the drive sounds like it keeps spinning up every 10 seconds or so. This is not an issue when trying to sleep when running on the battery only. Any advice?

    Double check your power settings for battery and when power is connected. Reset them and see what happens.

    I reset the Energy Saver preferences to defaults, but that did nothing. I then deleted the com.apple.PowerManagement and com.apple.AutoWake plist files, and rebooted the machine. That worked for a while, but then the problem recurred.

    I have the sleep issue even when logged out of all user accounts (which I realized after trying to sleep the machine while at the login window). Also, I had read the Apple support document prior to posting, but nothing from it really applies.
