Steps to reproduce the problem:
1. When device is in tablet mode
2. power button on side does nothing but turn off the device

What is the expected behavior?
I should be able to turn off the screen without turning off the device - a behavior expected from a "tablet" but not from a "laptop"

What went wrong?
Device powered down instead of going into some sort of active standby mode

Did this work before? No
