Prevent Surface Pro 3 Waking

Q: My Surface Pro 3 wakes from sleep on its own; how can I stop this?

A: I love my Surface Pro 3; however, a problem I have and that other people have had is that after I put the Surface Pro 3 to sleep, if I pull it out of my bag 2 hours later, it's still hot and the battery is nearly flat because the device woke itself up. I finally sat down and dug into the problem, which has a very easy solution.

Note that when you open the keyboard, the machine will no longer automatically wake. You'll need to press the Power button for the Surface to wake, but the device should no longer automatically wake when you don't want it to.

If this doesn't solve the problem, run the following command to look for the device that last woke the system:

powercfg /lastwake

If this command doesn't provide the information you need, you can run the following command to check for devices that can wake the machine:

powercfg /devicequery wake_armed

(Keep in mind that this command often returns no devices.)

Finally, you can try running the following command to check for any device that has the ability to wake the machine (e.g., a mouse, an HID device) and then disabling that device:

powercfg /devicequery wake_from_any
