It's simply a matter of being careful not to damage any of the zero insertion force (ZIF) connectors that the flat ribbon wires are locked into.
You should start with a clean organized location to perform the procedure, when you remove screws try to lay them out in an order that makes it easy to place them back in the same holes they came out of.
Be careful not to force any panel parts to the point their locking tabs break, I know it is sometimes tough to know without detailed disassembly instructions where all the hidden locking tabs and screws are. Sometimes there are screws hidden under the rubber feet on the laptop bottom. Those rubber feet have to be pried out to find hidden screws.
What-ever you do, do not force anything apart, once you crack or break the plastic parts they look like hell and sometimes do not fit right afterward.
I will try to find you a service manual and link you to it if I find one.
Other-wise I can link you to a few web sites related to other brand of laptops which you can use as a guide.
Here are a few links to use as a reference.
