I've disassembled many laptops. The method to disassemble each one has been very different from the others.
The method I always use is being extremely observant, staying patient, removing any screws that are accessible at the stage I'm currently at, and gently moving parts in different directions to determine what part(s) can be removed next.
FYI: I wouldn't just go hacking away at the keyboard with a screwdriver, that's a good way to destroy the keyboard. On some of my laptops, there were little spring-loaded tabs that held the keyboard in place. I would have to first push one back with a pin and then the other. After that, the keyboard could be lifted slightly and rotated over in order to access the main board where the cable that connects the keyboard to the main board could be detached.
If you search around on the web, you can sometimes find manuals or images people have produced that show how to disassemble your specific model.
