U.KEEP_AWAKE

Summary

If present in any open workbook, Windows is prevented from entering sleep mode

Syntax

=U.KEEP_AWAKE([screen_required])

Parameters

Parameter Required Description
[screen_required] No If set to TRUE then the screen will also be prevented from darkening or displaying a screensaver. This can result in needless energy consumption so should only be done in cases where nobody is interacting with the computer but the screen must still display the Windows desktop

Behavior

The documented public interface is supported by the current U Add-in source signature and the maintained Usage Examples workbook. Optional parameters are shown in square brackets in the syntax above; omit the brackets when entering a formula.

Return Value

Returns the function result or action status described by the formula and parameters above. The maintained sources do not define a narrower, stable return contract for this function.

Examples

=U.KEEP_AWAKE()

Notes

  • Formula examples are preserved from maintained workbook usage and normalized to the current U. prefix.
  • Complete formulas demonstrate working patterns; they do not imply that undocumented option values are supported.
  • Where maintained sources do not specify every accepted value, default, or error message, this page does not infer one.
  • For functions that perform actions, use a visible trigger or supported block/throttle parameter to avoid unintended repetition during recalculation.
