Yoga 370 random black screen after sleep

Hi,

 

I have the device since 2-3 months. Since some time, the yoga has problems coming back from sleep. 

 

Usually i press the button, or open the lid and the device starts to the login screen in 2-3 seconds. 

 

Sometimes, pressing the button or opening the lid does not work. The power button light stops "breathing" and turns on, but the screen stays black. It looks random to me. Only way to solve this is to press power button for 10 seconds and reboot completely (tried different things, e.g. detaching, attaching external screen, press the button shortly, close and open the lid). 

 

I turned of hybrid sleep and fast startup, but did not help.

 

Somebody else experiencing this? 

 

Any solution available? 

 

Best regards

Check in Device Manager for - Intel Management Engine(under System devices). Check properties and see if there is a power management tab, if so uncheck the box for "Allow the computer to turn off this device to save power".

I have this problem as well. Will try the suggested method.

I'm on latest drivers and BIOS.
