After you put a Windows Vista-based computer to sleep (S3), you may be unable to use a remote control to wake up the computer. However, you can use the mouse or the keyboard to wake up the computer.

This problem occurs if you install a TV tuner that has an integrated infrared (IR) remote control in a specific Peripheral Component Interconnect Express (PCIe) slot.
