My mbp wont sleep unless its folded. I've sent the energy preferences to sleep when folded and also when idle for sometime. I've realized the indicator light (white light to the right below keyboard) will light up slowly and go out every 5 seconds or so. Im assuming its sleep when it does that, but if I leave it for like an hour the light is just dimmed and NOT sleep. Anybody else having the same problem and/or what should I do about it?
