Opening the Computer
1. Place your computer on a clean, flat surface.
2. Shut down your computer. Disconnect the power cord and any other
cables connected to the computer.
Warning: Always turn off your computer before opening its case
to avoid damaging its internal components.
Warning: The internal components of your PowerBook may be
hot. If you have been using your PowerBook, wait 30 minutes
after shutting it down to let the internal components cool before
continuing.
3. Place a towel or soft cloth on a table in front of you. The towel or cloth
will protect the keyboard and display area of the PowerBook when you
flip it over to remove the bottom case. Make sure it covers an area large
enough for your PowerBook and that it hangs over the edge of the
table.
4. 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.
