4. Place a towel or soft cloth on a table in front of you.

(Figure 1A)

The towel or cloth will protect the keyboard and display area of the PowerBook when
you flip it over to remove the battery and bottom case. Make sure it covers an area
large enough for your PowerBook and that it hangs over the edge of the table.

5. With the display open at an angle greater than 90 degrees, carefully flip the
PowerBook over and lay it flat, fully on the table. Make sure the display hangs over the
edge of the table and rests lightly on your lap.

Do not open the display farther than the angle shown.
