By default, host sessions are disconnected when the computer enters a low-power state, such as Standby or Sleep. Even though the session reconnects when the computer "wakes," this process resets the connection and data may be lost as a result.
There are two ways you can prevent host sessions from disconnecting when this occurs. You can either prevent your computer from entering system standby mode or, you can configure the computer to keep the host connection alive whenever it enters standby mode. The latter method is more suitable for laptops and other battery-operated devices. Instructions for these two methods are provided as follows.
To prevent Standby or Sleep mode
Use the following procedure to prevent the system from entering system standby mode or causing the computer to shut down in a low-power situation. (For instructions on changing system power options, which can also cause the system to enter standby mode, see the Windows Help.)
In the Accessory Manager, choose> .
Click thecheck box until a check mark appears and then click to close the dialog box.
NOTE:On Windows 7 or Vista, if the check box is colored or cleared, the computer can enter standby mode. On Windows XP, if the check box is colored, the computer will notify the user before entering standby mode (the default); if the check box is cleared, the computer will enter standby mode without notifying the user.
