Sleep screen command in Grid 3

Updated December 2020

Grid 3 version 3.0.20 introduces the Sleep screen command which can be added to your grid sets.

What does Sleep screen do?

The Sleep screen command allows the user to turn off the device screen to save battery while the device is not in use. Once activated, the screen will switch off, but the device will remain active. Your enabled access methods will turn the screen back on.

  • Move the pointer
  • Touch the screen
  • Press a switch
  • Gaze at the centre of the screen
  • Say your wake up phrase

Configuring Sleep screen

You can enable Sleep screen options in Computer settings. Under the Sleep screen options you can toggle dim screen after a certain time and how long til the screen switches off.

For users accessing their device with eye gaze, gazing at the screen will wake the screen. In Sleep screen settings you can configure how long the user needs to gaze at the screen to wake it up.


Some USB devices attached to your device could interrupt the sleep process. In Device manager check for the “Allow the computer to turn off this device to save power” option by right clicking and selecting Properties. USB Hubs, keyboard, mouse and touch screen should be checked.

If the devices screen will not go to sleep, or wakes immediately please check you sleep options in Control Panel > Power options and check that Balanced or Device specific is selected, then edit plan settings and set all Sleep options to Never.


Using Sleep Screen after Windows update 2004 / 20H2 (December 2020)

A recent update for some Windows devices means some of our older Grid Pad devices no longer support the Sleep Screen command. If your device no longer supports Sleep Screen you can put your device to sleep (turn off-screen) However, you cannot wake your device using any AAC access method. If you press your power button or click your mouse your screen will turn on.

If your device has been updated and you are no longer able to wake the screen with your AAC method, we have a solution for you. 

  • Please download the following file SLEEPv1_1.exe (by default it will be saved into your Downloads folder )
  • Once downloaded right click and select “Run as administrator” 
  • A black box (cmd window) should flash up and then disappear from your screen. 
  • Now please restart your device 
  • You should now be able to wake your device using your AAC access method. 

Technical information

The SLEEPv1_1.exe adds a registry entry to disable modern standby. 



Using other devices with Sleep Screen

The Windows update forces devices to use the S0 Sleep state if available.

If your device does not support S0 sleep state, the Sleep Screen will still work.

To test if S0 Sleep state is available on your device please run the following command in an elevated cmd prompt window powercfg /a
