Keyboard lock up or key not responding

October 2015

Sometimes the "Word Completion" feature of the operating system can interfere with key entries. To disable this feature, tap on Start > Settings > Personal > Input, click on the “Word Completion” tab, uncheck all options listed, and then tap OK.

 

If the period or any other hardware key is not responding properly such as after a previous repair, you could try downloading (do not extract) the following file, copying it to the Allegro 2, running it from File Explorer, and then soft Reset.

 

AG2-Update-Keyboard.cab

 

If the keyboard is not responding on a Carlson Surveyor 2 unit, the custom keyboard map may need to be reloaded or updated. Please see the following web page for more information.

Similarly, if a key or a few keys will no longer respond, the keyboard map in the Windows registry may be corrupt. If available, the Windows registry could be reloaded from a previous backup (such as created using the utilities listed at the following web links). Or you may need to perform a full Clean Boot (Set Factory Defaults) to restore the Windows registry.

 

  • Registry editors
  • System Backup utilities
  • Clean Boot - Hold the Power button for a full count of 15-20 seconds until a blue screen with sliders appears, move the "Set Factory Defaults" slider, and then tap Exit. This will remove all installed apps and data.

 

For developers, the custom JSHome screen may be active and intercepting key strokes. If needed, changing the following Windows registry key may help. Updating the operating system (such as to A2 OS release 1.7.2 or higher) may help prevent this issue.

 

[HKEY_LOCAL_MACHINE\Software\JuniperSys\JSHome]

"Active"=dword:0

 

Otherwise, if you suspect that the keyboard hardware may need servicing, please contact a certified repair center.
