Windows 10: Kiosk mode shows white screen after waking up from sleep

I have a kiosk using assigned access that’s been operating for approx 2 months without any issues until this week. About three days ago it started to show a blank white screen after waking the computer from sleep. I’m at a bit of a loss as too what happened as it was running perfectly until three days ago. I reviewed windows updates and there was no driver updates but feature update 2004 was installed about 6-7 days previously so maybe the feature update screwed something up. I tried googling but haven’t really found any solid answers besides adjusting power settings which haven’t fixed it. I do have logging enabled but haven’t had a chance to review yet. Does anyone have any suggestions what it might be?

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.

Hi,

There are different factors that can contribute as to why the computer screen would display a white background with a lot of dots showing after you wake the computer from sleep mode. This could be caused by a recent update or device drivers that got corrupted.
For us to resolve your concern, kindly answer the questions below:

• Were there any recent changes or updates installed on your computer prior to the issue occurring?
• Were there any error messages that showed up on the computer screen?
• Which version and build of Windows 10 is installed on your computer?
