I've been trying to figure out why my tMBP 13 drains more than needed battery while sleeping. I finally noticed that messages is waking my MBP up every time i get or send a message. I keep my MBP open while it's locked, and it doesn't seem to ever go into full hibernate mode. I know one solution is to just manually set how long before hibernate. I've been intentionally avoiding this to troubleshoot the cause of the sleep battery drain. If this is the only way, I will do it. I don't really need my computer to only be in sleep vs. hibernate, so I can set it to a couple minutes and be done with it. I believe I can also just close the lid, but I want to avoid that so I don't have to open and close the lid while at my desk station. Ideally, I'm just looking for a way to shut off wake on message, but I can't seem to find it. I have done a search both on MR and internet, no luck. Anyone know the solution?
