Symptoms

Consider the following scenario:

  • You have a computer that is running Windows 7.

  • You configure the computer’s power button so that it can be used to hibernate the computer.

  • You change the Password protection on wake up setting so that the Require a password (recommended) option is selected.

  • The computer enters hibernation.

  • You press the power button to resume the computer from hibernation. You are prompted to enter your user account credentials.

  • The computer enters hibernation again while you are trying to log on. 

    For example, the computer enters hibernation because of low power or because you press the power button by mistake.

  • You press the power button to resume the computer from hibernation again.

In this scenario, the computer screen dims after you log on.

Cause

This issue occurs because two threads try to fade out the monitor at the same time.
