Einleitung

This is a difficult guide so make sure you are completely prepared before doing it. Note that thorough removal and cleansing of the old heatsink paste and correct application of the new are vital, otherwise you are likely to make matters worse. Always eliminate a clogged fan or cooling vanes as a cause of overheating before replacing the heatsink paste.

Use of an anti-static wrist wrap is highly recommended. Take care not to use too much force especially for the zero insertion force ribbon cables.

    • Remove the 3 Phillips #0 screws from the fan bracket.

    • Lift the fan up and place it back down above the heatsink.

    • Do not fully remove the motherboard. As there is hidden cable on the underside that could be damaged.

    • The heatsink has a strip of adhesive on the underside securing it to the plastic body.

    • The motherboard can be lifted from the side and and then to the right to free the I/O port from the enclosure. Some force may be required to release the heatsink.

    Can you help me out? I’m having trouble lifting up the fan. It seems to be stuck to the metal part near the vent on the side and I can’t figure out how to lift it, Any tips?

    I broke my touch pad zip connecter .Then what can i do ?

    Muhammad Ayub Zahid -

    If it’s the locking bar that’s broken you can sometimes wedge some packing into the connector to enable it to make a good connection with the ribbon. A proper fix would be to fit a new connector, but that would require microsoldering skills which I guess you don’t have. It’s possible you could find a repair shop that could undertake it - quite easy with the right equipment and skills. Undoubtedly the easiest thing is just to forget about the touch pad and use an external mouse instead - many people prefer it anyway.

    • Rotate the motherboard to the right and lay it down so that the copper heatsink is facing up and parallel with the bottom of the monitor.

    • In this position the last cable to the motherboard can be disconnected using the spudger to push each end out until loose enough to pull the cable completely out.

    • The motherboard can now be completely removed from the laptop enclosure.
