The display brightness may change after the computer resumes from a low-power sleep state on a Windows Vista-based computer

SYMPTOMS
When a Windows Vista-based computer resumes from a low-power sleep state, the display brightness may change.

This problem occurs if one of the following conditions is true:
  • You temporarily change the display brightness before you put the computer to sleep by using Windows Mobility Center or by using function hotkeys on a mobile computer. Windows Vista stores a brightness preference in power policy and reapplies that preference every time that the system resumes from a low-power sleep state, such as sleep or hybrid sleep.
  • The computer BIOS change the display brightness when the system resumes from sleep.
WORKAROUND
To permanently change the brightness of the display, follow these steps:
  1. Click Startthe Start button, click Control Panel, and then click Power Options.
  2. Click Adjust Display Brightness.
  3. Change the display brightness of the computer, and then click Save changes.

    Note If the computer does not display the Adjust Display Brightness option, check with the computer manufacturer for an updated BIOS to support this option.
STATUS
This behavior is by design.
