My macbook is having some weird issues trying to sleep/hibernate. Whenever I am using a USB port, I shut the lid to put the macbook asleep, and then remove the USB. After doing so, the macbook will just wake itself up. I check the system logs and it looks like it sleeps itself and wakes itself until it runs the battery dry. I actually charged it Full one morning, put it in my bag for school, and when I took it out to use (5 hours later), it was out of battery. If someone could help me figure this issue out, it would be greatly appreciated. I was wondering if someone could test this on their macbook. Put in any USB drive, mouse, keyboard, and shut the lid. Wait and see if your sleep light will pulsate, or see if it wakes up. It takes about 15 secs. Thanks a lot guys.
