Consider the following scenario:

• You are running a Windows Vista-based computer.
• An LCD monitor is connected to the computer.
• The computer exits Away mode because of a timed event, such as a scheduled recording in Windows Media Center.

In this scenario, the LCD monitor unexpectedly turns on.

For example, consider a scenario in which the following specific conditions are true:

• On a Windows Vista-based computer that has Away mode enabled, you schedule a TV recording in Windows Media Center.
• You press the power button on the Media Center remote, or you press the SLEEP key on the keyboard. The computer enters Away mode.

In this scenario, the LCD monitor unexpectedly turns on when the scheduled TV recording starts.

You use a computer that is running Windows Vista Ultimate or Windows Vista Home Premium. The computer has an integrated LCD screen that is built into the computer’s case. When you use the integrated screen to watch a video that uses a 50-Hertz (Hz) Phase Alternating Line (PAL) signal, the video playback quality may be poor in Windows Media Center. The video may be choppy, jerky, or not smooth.
