    Default my XPS M1730 touchpad & Keyboard not working (HELP)

    hello!
    i am Noman From Pakistan
    i worked in GSM filed recently i got a Dell XPS M1730 from a friend, its a brand new laptop, its touch-pad, keyboard and charging not working i tried many time to solve it but fail, some time charging works some time keyboard works but only for some time then goes dead again.
    i open it and saw its very cleaned nobody touch it in inside not water damage and also no other damages
    i think if touch pad works properly then also keyboard will be OK and charging also will be fine, because when i remove touch-pad from PC AC power also off only battery power works when i attach again touch-pad AC power works again

    also i get error of AC adopter when i start PC that please connect AC230 power adopter and i already connect it with AC230 original power adopter
    any body can help me what is the problem i check all drivers working fine also i checked with windows XP, Vista and 7. when i saw device manager and i show hidden devices i saw dell touch-pad with yellow icon i checked it it show device not connected.
    please help me in this mater i will be very great full to you brothers

    thanks in advance

    sounds bad.

    Is it under warranty?

    The control for touchpads and keyboards especially is not in the part, meaning if you replaced the keyboard and touchpad you may still have problems. So its likely the motherboard.
    Try running the diagnostic at different times like when you said you got it to work correctly.

    You could also try disconnecting the keyboard. Pry of the hinge cover (the part that has "XPS" in red letters), unscrew the 4 screws holding it down, and slide it up about 1/2" right after pressing the power button.

    Power keys are located on the top bezel which is on an independent rail from the keyboard, althought they share the same connectors.
    I think that your problem is that the motherboard is going to die soon. The keyboard and touchpad controller hooks up with the palmrest area by a thin cable, located on the bottom left corner of the motherboard.
    Theres the controller too. I suspect that the controller is almost dead, remember that some motherboards where faulty, some others get faulty in the time, so maybe its your turn, which is sad.
    I advice to send it back to dell if you have any warranty left. If not, you can buy a new motherboard off ebay, they are cheap as well, so maybe with a little effort you can fix it by yourself.
    Anyway what happens if you plug in an usb mouse or keyboard, does it work ok? It should since they use the usb controller instead of the builtin keyboard controller.
    Good luck mate, im sorry to hear you're having problems with it.
