What about the WM_POWERBROADCAST message (at least for non-WinCE 
apps)?
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/power/base/wm_powerbroadcast.asp


From its docs:

LRESULT CALLBACK WindowProc(
  HWND hwnd,       // handle to window
  UINT uMsg,       // WM_POWERBROADCAST
  WPARAM wParam,   // power-management event
  LPARAM lParam    // function-specific data
);

Parameters

hwnd
Handle to window.
uMsg
WM_POWERBROADCAST message identifier.
wParam
Power-management event. This parameter can be one of the following 
events. 


Event
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_APMRESUMEAUTOMATIC
Operation resuming automatically after event.


PBT_APMRESUMECRITICAL
Operation resuming after critical suspension.


PBT_APMRESUMESUSPEND
Operation resuming after suspension.


PBT_APMSUSPEND
System is suspending operation.

lParam
Function-specific data. For most events, this parameter is reserved 
and not used. 

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


Return Values


Return TRUE to grant a request.


Return BROADCAST_QUERY_DENY to deny a request.


Requirements


Windows NT/2000/XP: Included in Windows NT 4.0 and later.
Windows 95/98/Me: Included in Windows 95 and later.
Header: Declared in Winuser.h; include Windows.h.
