In a Tecra A2 laptop many major components can be accessed from the bottom. Simply by removing a few doors from the bottom of the laptop, you can access and replace the hard dive, memory, wireless card, dial up modem. Also you can access the processor and clean the heat sink.

The keyboard removal instructions could be found in steps 8-12. The DVD dive can be removed only after you remove one screw securing the drive under the keyboard.
