    Hi I'm using X200 running windows 7.

    At office, I put it to sleep (ensured that the sleep light is on) and place in my backpack. However, when I'm home and reach my laptop again, little did I know I find it turned on by itself and is really warm. This has happened 3 times so far.

    And when I'm at home and put to sleep at night. In the morning, I find that the sleep icon is off and already came to hibernate.

    Any ideas what happened? It appears out of control. Please help.

    Thanks in advance.

    I'm running win7 on my X200s as well, but I haven't experienced this. I'm just using the stock windows 7 power management, with no extra Lenovo utilities or ThinkVantage or ProductivityCenter stuff.

    If it jumps from sleep to hibernate on battery power, it could be due to running out of power - that would be by design.

    Perhaps you should try disabling Wake On Lan in the BIOS (not sure how that would unintentionally be involved here) and look for any other power management sw running that could be messing with Windows 7's power management.

    why dont u just hibernate or turn it off completely?
    depending on how much ram you have.. hibernating shouldn't be that painful.

    By default, the Balanced Power Plan hibernates the laptop after 8 hours on idle I believe.

    thanks all bro flynn337, davidkneiber, surfasb! i found the culprit of my problems finally.

    first, after i put to sleep then i unplug my usb mouse/other usb devices, that causes it to wake up again, now i'm trying to find how to disable that

    second, i found this setting under advanced power option > sleep > hibernate after > mine is set to 360 minutes plugged in. this explains why it is auto hibernated

    Yes, the default behavior in Vista and Win7 is to wake up on USB device removal. I believe you can disable it per device, as described in this Microsoft article. However, I would just suggest unplugging it right before closing the lid :rolleyes:
