Sleep screen or wake on touch issues after Windows Update 2004/20H2

Devices affected: Grid Pad 8, Grid Pad 10, and Touch Pad ST10B, Legacy devices

A recent update for some Windows devices has removed a vital Windows power plan that enables waking via the touch screen.

This can limit your device’s ability to wake from sleep successfully.

Note: You can find out if you have the ST10B version of Touch Pad by looking at the label underneath the stand.


There are 2 options to resolve this issue:

You can no longer set your device to sleep via the power button and wake on touch. Instead, you can choose to:

  • Wake your device on touch, and use the Sleep screen command in Grid 3 command to put your device to sleep. (Our Support Team can enable this for you via a registry fix – see below for further information)
  • Wake and sleep your device by the power button


Enabling wake on touch

We can provide a registry fix that will allow you to wake your device with a press of the touch screen. However this fix will disable sleep and wake using the power button and you will need to use the Grid 3 Sleep screen command to put your device to sleep.

Please contact Smartbox Support who can install this registry fix for you.

Note: The registry fix can cause the following side effects if you try to put your device to sleep by pressing the power button:

  • Black screen appearing over Windows – requiring a restart to remove.
  • Loss of touch screen access
  • A sudden shutdown
  • System crashes

All future Smartbox devices will have this registry fix installed by default. If you do not require the device to be woken up by pressing the touch screen – contact our Support Team. We will remove the registry fix and enable your device to be slept and woken via the power button.


Add the Sleep screen command to your grid set

You can find out more about the Sleep screen command in this article. This command will also enable users to save battery when the device is not in use.
