My computer is not hibernating or going to standby every time I close the lid. It does shut down initially when I close it, but less than 2 minutes later, it will start up again. Especially overnight, it will generally restart (when the lid is closed) about every 2 minutes the entire night. I've tried manually putting it into hibernate/standby and the same thing happens (goes to it, then restarts after a bit). This is draining all of my battery so I really can't take my laptop anywhere without my charger and a power outlet. Anyone know what's wrong? Thanks!
