If you own a Surface, you probably know that there are times when the device can magically wake itself up in your bag or in it’s carrying case. You end up with an overheated device and your battery drained considerably.
Much of the time, the reason for this is the Surface keyboard, which when moved can wake the device up. The solution is to disable the keyboard’s ability to wake your Surface.
DISABLING THE KEYBOARD’S ABILITY TO WAKE COMPUTER:
To fix this, follow these steps:
1. Go to Device manager—> Keyboards –> Surface Typecover Filter Device
2. Select Properties
3. Select the Power Management tab.
4. Uncheck the box entitled, “Allow this device to wake the computer”.
5. Reboot.
