WM_POWERBROADCAST Overview  Group

The WM_POWERBROADCAST message is sent to an application to notify it of power-management events.

dwPowerEvent = (DWORD) wParam;
dwData = (DWORD) lParam;

Parameters

dwPowerEvent
Event notification message. This parameter can be one of the following values:

Value

Meaning

PBT_APMBATTERYLOW

Battery power is low.

PBT_APMOEMEVENT

OEM-defined event occurred.

PBT_APMPOWERSTATUSCHANGE

Power status has changed.

PBT_APMQUERYSUSPEND

Request for permission to suspend.

PBT_APMQUERYSUSPENDFAILED

Suspension request denied.

PBT_APMRESUMECRITICAL

Operation resuming after critical suspension.

PBT_APMRESUMESUSPEND

PBT_APMSUSPEND

dwData
Function-specific data. For most messages, this parameter is reserved and not used.

However, if wParam is one of the resume notifications (PBT_APMRESUME*), the lParam parameter can specify the PBTF_APMRESUMEFROMFAILURE flag. This flag indicates that a suspend operation failed after the PBT_APMSUSPEND message was sent.

Return Values

Return TRUE to grant a request.

Return BROADCAST_QUERY_DENY to deny a request.
