In the Power Options item in Control Panel, the "Estimated UPS capacity" field remains unavailable after you reconnect a Smart-UPS device to a Windows Server 2003-based computer

Consider the following scenario:

• You are running a Windows Server 2003-based computer.
• You disconnect a Smart-UPS device from the computer, and then you reconnect the device.

In this scenario, the Estimated UPS capacity field remains unavailable (appears dimmed) on the UPS tab of the Power Options item in Control Panel.

This issue occurs because the Estimated UPS capacity functionality is not re-enabled after the Smart-UPS device is reconnected.
