Hi bud to replace the fan you will ned to remove all the screws underneath including the three holding your keyboard, the turn over your laptop with a very small glasses screw driver remove the keyboard which is held by three clips running along the bottom inside edge of keyboard. then you will find a further two screws holding the casing. then unplug the two conectors you can see holding the casing one runs from the mouse pad the other is instrument panel now lift off casing being mindful of the pcmcia card holder then unplug fan and remove the two holding screws either side. When putting back together the keyboard connector on the motherboard pulls down and then you lift it slightly about 30 degrees which is so you can slide the connector in place then push it back into positionthe rest should be easy all my best ric
