Running on battery, I close the lid to enter sleep. When I open the lid, the keyboard lights appear normal, but the screen stays black/off. I have to hard boot to get it to work again. New X1 Carbon running Windows 10. This has happened several times. Any ideas what's causing it? Thanks.

Maybe you can try re-installing the power management driver.
