PBT_APMRESUMECRITICAL
The
PBT_APMRESUMECRITICAL message is sent as a notification that the system has
resumed operation after a critical suspension caused by a failing battery. A
driver receives this message through the WM_POWERBROADCAST message.
dwData = (DWORD) lParam;
Parameters
dwData
Reserved;
must be 0.
Return Values
No return
value.
Remarks
Because a
critical suspension occurs without prior notification, resources and data
previously available to a driver may not be present when the driver receives
this message. The driver should attempt to restore its state to the best of its
ability. While in a critical suspension, the system maintains the state of the
DRAM and local hard disks, but may not maintain net connections. A driver may
have to take action with respect to files that were open on the network prior
to the critical suspension.
This message
is not sent to applications.
