Windows 10 - Problem waking up from sleep mode

This worked for me on a Lenovo Horizon2 27 all-in-one PC that was able to sleep manually but could not be wakened once sleeping after upgrading to Windows 10 Home.

I ran the powercfg /energy and examined the report as GoWMike describes. It showed no driver errors but suggested that there is a problem with the system's "High Performance" power setting that may prevent normal waking from manually induced sleep.

I used powercfg /list to show available modes, copied the GUID for Balanced mode, and then used this with the powercfg /activate command to change the plan.

I also used powercfg /devicequery wake_from_any

to get a list of device names for components capable of waking the system from sleep, and then I used

powercfg /deviceenablewake <devicename>

to make certain that the touchscreen and power button are armed to wake the machine.

After restarting, sleep and wake then functioned properly again.
