Lid Switch

This section describes the expected behavior of the system when the lid is opened or closed by the user. If the system is running under legacy mode:

  • Closing the lid will turn off LCD backlight. If the system is running under ACPI mode:
  • The operating system will determine what action to take when the lid is closed. (Windows does not define Lid Open action in Power Option control panel)
  • The function of lid close will follow the OS setting in power management (Nothing, standby, Hibernate or

Power off). However, if the setting is nothing, the backlight must still be turned off when the lid is closed.

□ Lid Open action does not resume the system from S3, S4, and S5.
