Laptop lid closing/opening events? RRS feed

  • Question

  • Hi,

     

    In windows 7 power management, there is a way to specify desired behaviors (sleep, hibernate, do nothing, etc) when the laptop lid is closed. Therefore there windows must somehow know the lid is closing.

     

    I tried to find a way to detect such a event, however I can only find suggestions to intercept events when the computer is entering/leaving sleep. This is not exactly what I am looking for, because I want to capture the event when the lid is closing, regardless whether or not it is going to sleep as a result of the lid closing.

     

    Could any one suggest the correct event to monitor?

     

    Thanks

  • Registering for Power Events

    wait for GUID_LIDCLOSE_ACTION.

    See also Power Management in Windows XP. It does talk about lid closing but did not give specific details on which ACPI event would be raised.

  • Wrong answer!

    msdnuser2010 want to capture the lid close event not the lid close action.

    If you register a handle for GUID_LIDCLOSE_ACTION with  RegisterPowerSettingNotification, this will not be triggered at lid close. This will be triggered only when, in Control Panel -> Power Settings you will change the action for lid close.
