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.
