SYMPTOMS
A portable computer does not shut down as expected when the battery power is low. Instead, the computer performs a critical shutdown when the battery power is exhausted. This is the case if the following conditions are true:
 * You configure the Power settings to shut down the computer when the battery power is critically low.
 * You watch live TV in Windows Media Center when the computer is running on battery power.
 * The battery power is drained to a critically low condition.

Additionally, you may receive the following error message:

The device driver for the  device is preventing the machine from entering standby. Please close all applications and try again. If the problem persists, you may have to update this driver.

However, you expect to receive a message that the system is shutting down because the battery power is low.



CAUSE
This problem can occur with some TV tuners that prevent the system from entering standby when you run live TV.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
