    For all three of those to not work anymore after you disassembled the laptop and touvhed the motherboard makes me believe that something hardware related happened.

    I more thing to try is shut it off, unplug and remove the battery, hold the power button down for 30 seconds.

    Plug it in and try it.

    Did you remove them from the screen or the motherboard?

    I would try reinstall the touchpad driver and the audio driver first.

    Then I would disassemble again, paying close attention to connections and grounds.

    It's also easy to short things out with static from your body.

    Yes I remove them from motherboard. And attached all items as they are there before. I only remove keyboard, touchpad, wifi card, speakers, micrphone and display connection cable. And Now only Display work other all items keyboard, touchpad, wifi card, speakers, micrphone stop working. Keyboard don't work even in booting time. After booting when windows starts just before the windows account open the function key of keyboard work. that time i can only adjust the brightness of the pc. this key works about 4 or 5 seconds till windows desktop appear then it again becomes dead.

    When you replaced the mic and speaker wires on the motherboard, could you have put them on the wrong connector. They will interchange.

    Did the wires go through the hinge you repaired? Could you have pinched them when you reassembled? I'm hoping you didn't short out anything when you were touching things on the MB.

    No, the wires are not close to the hinge which  i repaired. one thing which i want to tell you that when i connect my laptop with an external speakers, then the speakers don't work but these speakers works well when i connect it to another pc. so the problem is that the external devices is also not work with its inbuilt devices.

    what i do ? please  help me.
