My Toshiba Satellite L750 laptop will not go to sleep anymore. It is running Windows 7 Home Premium. There were no hardware or software changes I made that caused this, but something could have automatically updated to a version that does not work properly. When I close the lid or let it go to sleep automatically, it will wake up a second later.
I don't see anything preventing it from going to sleep in the power options. I have looked at all of the options listed here:
The only device that is allowed to wake the computer is the Ethernet controller, but I am using a wireless connection and wake on LAN is disabled in the BIOS. The mouse and keyboard were allowed to wake the computer, but I disabled that option. Sleep did work at one point with the keyboard and mouse allowed to wake the computer. This is something that only started recently. I first noticed this last week.
