Disconnect the power cord and any other cables connected to the computer. 073-0596 Rev. B 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. (Figure 1B) Important: Do not open the display farther than the angle shown. Figure 1 A B 6. Remove the battery by sliding the battery latch to the left. Make sure to return the latch fully to the right.

(Figure 5) Figure 5 10. Touch the computer’s inside framework (a dull gray conductive composite material) to discharge any static electricity, as shown. (Figure 6) Important: To avoid electrostatic discharge damage, always ground yourself by touching the computer’s framework before you touch any parts or install any components inside the computer. To avoid static electricity building back up in your body, do not walk around the room until you have completed your installation and closed the computer. Figure 6 PowerBook G4 Hard Drive -4 Removing the Installed Hard Drive 1. With your fingers, carefully pry up the hard drive flex cable connector (Figure 7A) at its sides to disconnect it from the logic board.You may need to pry one side, then the other, in a rocking motion. Figure 7 A 2. With a Torx T8 screwdriver, remove the two screws (Figure 8) that secure the hard drive to the mounting bracket and then gently remove the hard drive. Important: Do not pull on the flex cable or use the cable as a handle. Figure 8 Note: There are four rubber stoppers on the hard drive that fit over screws (two on each side). Remove any that may have fallen off or that remain in the holes in the mounting bracket inside the computer. 3. If not included with the replacement drive, remove the Mylar sheath and the flex cable to transfer to the replacement drive. Important: The connector pins on the hard drive are fragile and bend easily. Use care to keep the pins straight when removing or installing the flex cable. PowerBook G4 Hard Drive -5 Installing the Replacement Hard Drive Warning:To avoid potential injury, avoid touching or brushing against the thin strip of metal that extends up from the hard drive mounting bracket (Figure 9A).
