    USB ports giving out energy when laptop is on sleep mode

    Hi guys, I really don't know if this is the right place to make this post . Whenever I put my computer on sleep , the USB ports still give out energy when a phone or an external device is plugged into the ports , So I would like to know how can I stop my USB ports from giving out energy when laptop is on sleep mode.
    Hope to get some help
    Thanks in advance

    The only way would be to shut the system down.

    As broe23 says, shutdown the system totaly should turn of power for USB as well.

    But remember even though you shut it down, or putt it in sleep mode, some motherboards continue to transmit power through USB.

    Have a computer with windows 7 and a G41M-Combo motherboard and even though its shutdown it continues to transmit power.
    But then again, that is a desktop computer.

    Now if you disconnect the power cord from your laptop then the option about the laptop still continues to transmit power should halt, since then I would belive the motherboard BIOS is setup to save the battery power.
