# HandleCheckPowerState(void)

The HandleCheckPowerState (void) method is on the serialized side of the command gate and can change member variables safely without multi-threading issues. It's main purpose is to call the superclass' HandleCheckPowerState ( UInt32 maxPowerState ) with the max power state the class registered with.

## Declaration

```occ
virtual void HandleCheckPowerState (
 void ) = 0; 
```

## Overview

Overview The HandleCheckPowerState (void) method is on the serialized side of the command gate and can change member variables safely without multi-threading issues. It's main purpose is to call the superclass' HandleCheckPowerState ( UInt32 maxPowerState ) with the max power state the class registered with. Subclasses must override this method. Third party subclasses shouldn't need to override this method but can to alter the default behavior.
