Plugging in a sleeping MacBook Pro wakes it up RRS feed

  • Question

  • I have a 15" MacBook Pro with multitouch trackpad (released late 2008) with a clean installation of W7 RC (dual boot).  If I close the cover to the computer it goes to sleep correctly - i can see the glowing thing on the cover turn off.  I can open and shut the cover multiple times and it works like I expect.  However, if the computer is plugged in while sleeping it turns on.  The glowing logo on the cover lights up and after awhile the fans kick on.  I've left the machine on a table for hours like that and it never shuts back off.  I had the same problem with the beta of W7.  Has anyone else seen this?

  • When I run powercfg -lastwake i get this:

    Wake History Count - 1
    Wake History [0]
      Wake Source Count - 1
      Wake Source [0]
        Type: Device
        Instance Path: ACPI\ACPI0003\2&daba3ff&1
        Friendly Name:
        Description: Microsoft AC Adapter

    Then I ran this:

    powercfg.exe -devicedisablewake "Microsoft AC Adapter"

    And that fixed it!!  Thanks for the tip on the excellent powercfg utility.

  • Does the OS X side handle this properly? 

    On the Win 7 side, you might try getting into the power management settings in control panel and deleting/recreating the power management schemes, ensuring that you don't have one of the many "always on when connected to AC" or "Don't sleep when connected to AC" selections active.

  • Thanks for the reply - The OsX side does handle the situation propertly.  I couldn't find an option to delete the power mgmt schemes, but I did reset all avail power schemes to no avail.  Is there a specific option that governs what the computer does when plugged in?

  • Can anyone help me with this problem?:

    I have wiped the drive on my 2007 MacBook standard (1 GB RAM, no "Pro," runs native graphics WMA), and installed Windows 7.

    I installed the BootCamp Beta drivers directly from the disk (the auto-installer doesn't work), but only for the trackpad, keyboard, and audio drivers.

    I was able to install all of my necessary programs, connect to wireless home network, connect to work WPA network.

    Everything works great except for one thing:  Everytime it comes out of sleep mode (whether by time-out on battery or by closing lid), the LCD screen turns on without the backlight.  I can barely make out the graphics patterns in bright light, just enough to log in and navigate to shutdown/restart.

    Anyone have any idea how to fix this?  Is it a drivers problem?  Is it something Windows 7 should be able to automatically fix (built in drivers?)?

    I like Win7, by the  way.  Much better than XP in windows management (snap, etc).
