You must remove, replace, or loosen as many as 82 screws when you service the parts described in this
chapter. Make special note of each screw size and location during removal and replacement.
Bottom cover
You cannot completely remove the bottom cover, as it remains connected to the computer during
disassembly. You have to loosen the bottom cover and place it next to the computer so you can access
internal components.
Before loosening the bottom cover, follow these steps:
1. Prepare the computer for disassembly (see Preparation for disassembly on page 28).
2. Remove the pen (see Pen on page 28).
Loosen the bottom cover:
1. Using tweezers, pull up the right side of the protective strip from the pen holder (1), and then remove
the strip (2). A new protective strip is provided.
NOTE: Be careful not to scratch the pen housing.
