SYMPTOMS
When you try to export video from your portable computer, or from any other battery-operated computer, to your digital video (DV) camera, the export operation may not be completed successfully.



CAUSE
This issue may occur when all the following conditions are true:
 * Your computer is battery-operated.

Note: A portable computer may continue to use battery power even when it is connected to an electrical outlet.
 * Your computer is configured to use the Portable/Laptop power scheme.
 * Your DV camera is connected to your computer through an IEEE 1394 cable.

Note An IEEE 1394 cable is also known as a FireWire cable.

This issue occurs because the computer is configured to save power by putting certain processor functions into standby. This functionality may cause a buffer under-run.



WORKAROUND
To work around this issue, configure your computer so that it does not use a power-saving setting. To do this, follow these steps:
 * 1) Click Start, click Control Panel, click Performance and Maintenance, and then click Power Options.
 * 2) On the Power Schemes tab, click Always on under Power schemes.
 * 3) Click OK.

Note Your computer may have third-party power management software installed. See the product documentation for your computer if you continue to experience the issue that is described in the &quot;Symptoms&quot; section or if you cannot modify the power management settings by following these steps.
