You’ll need to follow the below to get the palm rest off, I’ll post details later of getting touchpad and mouse button pcb off if you need, then you’ll either be able to clean them where they are or remove, they are in a delicate plastic sprew / frame and it is fixed to the palm rest by melted pins. It can be removed with care and either re-melted with soldering iron, small old screwdriver heated in blow lamp or other flame… alternatively glued with an epoxy like araldite….
——————————————————————————————-
Remove Battery, Lay laptop on its lid upside down on a soft cloth or soft towel.
take out all screws you can see note the two under the battery are shorter (don’t get them mixed up when you replace)
there is another screw under the ram cover and two screws that hold the keyboard in under the rear self adhesive rubber feet, (also small ones)
when all screws are out turn laptop over carefully.
use a thin screw driver or pick to lift the top right corner of the keyboard just a little (hook it carefully under the delete / break key)
lift it just enough so you can hold it lifted with your finger now while holding it use the thin screw driver or pick to release the two catches above the F11 & F6 keys. they need to be pushed upwards away from keys. (if you can’t lift the keyboard don’t force it but check you have removed the two screws under the rubber feet).
Keyboard should now be loose. remove it enough to undo the connector the brown catch needs to be lifted with pick or thin screwdriver.
There is a connector just below the keyboard one that is a push / pull fit and one more screw not quite top left corner under where the Tab key would be when assembled.
The top cover / palm rest should come off now but you may have to wiggle it gently as there are a few clips on the front. Don’t force it. If it wont come off you have missed a screw somewhere:-
You should have 14 screws total.
1 short / medium (ram cover centre rear)
4 short, (2 for keyboard under rubber feet, 2 under battery).
9 long (7 in casing rear, 1 in ram compartment, 1 under tab key)
With top / palm rest removed the rest should be pretty obvious..

The above is how I do it but some of this is detailed on the forums with pictures so have a look there, (hdd replacement topic)

Before starting make sure you are earthed no static, and you’ll need jewellers screwdrivers or similar, a set of snap-on picks are useful to.
On reassembly don’t get screws mixed up, long ones where short ones go can damage the casing.
