For this computer, you can replace memory in either the upper or lower RAM slot. Replacing memory in your computer requires up to nine basic steps: • Turn off the computer. • Open the computer. • Remove the heat shield. • Remove the processor module (if replacing RAM in the lower RAM slot). • Remove the RAM you are replacing. • Install the replacement RAM. • Replace the processor module (for lower RAM replacement only). • Replace the heat shield. • Close the computer. Note: A video version of the replacement instructions is available at Tools Required • Jeweler’s flat-blade screwdriver • Phillips screwdriver Electrostatic Discharge (ESD) Static electricity, a normal and natural phenomenon, builds up on your body as you walk around.You experience an electrostatic discharge (ESD) when you touch an object and feel a spark. ESD can cause damage to the internal components of your computer. To avoid ESD damage, read and follow all instructions. If a grounding wrist strap is included with your replacement memory, refer to the instructions included for how to ground and use the strap. About Memory Your computer comes with a minimum of 64 megabytes (MB) of synchronous dynamic random-access memory (SDRAM) installed in a RAM slot on the bottom of the processor module. On the top of the processor module is another RAM slot you can use to add additional memory to your PowerBook. RAM Specifications The expansion slots on the top and bottom of the processor module can accept up to a 2-inch SDRAM card that meets the following specifications: • small outline-dual Inline memory module (SO-DIMM) format • 16, 32, 64, 128, or 256 MB • 144-pin • PC-100 Type RAM SDRAM from earlier PowerBook models cannot be used. Maximum RAM Configurations The maximum amount of RAM you can install in your PowerBook is 512 MB, using 256 MB DIMMs in both the top and bottom RAM slots. To install RAM in the bottom RAM slot, you must remove the processor module. To install RAM in the top RAM slot, do not remove the processor module. 2 - PowerBook (FireWire) Memory (RAM) Opening the Computer Warning: Always turn off your computer before opening it to avoid damaging its internal components. 1 Place your computer on a clean, flat surface. 2 Shut down your computer, remove the battery from the expansion bay, and disconnect the power adapter, modem, and any other cables connected to the computer. Warning: The internal components of your PowerBook may be hot. If you have been using your PowerBook, wait 30 minutes after shutting down your computer to let the internal components cool down before continuing.

Your new PowerBook comes with the keyboard unlocked, so unless you or someone else locked the keyboard, you can skip this step. 4 Release the keyboard by pulling down on the keyboard release tabs (located to the left of the F1 and F9 keys) until the top portion of the keyboard pops up. . PowerBook (FireWire) Memory (RAM) - 5 5 Lift the top portion of the PowerBook keyboard up slightly near the top row of keys and pull it back far enough to release the small tabs that hold the bottom of the keyboard in place. 6 Flip the keyboard over and lay it on the palm rests. 7 Touch a metal surface inside the computer to discharge any static electricity. Important: To avoid electrostatic discharge, always ground yourself by touching a metal surface 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. 8 With a Phillips screwdriver, remove the screws that secure the internal heat shield. . ScrewsHeat Shield 9 Lift up the internal heat shield. 10 At this point, • Go to the section “Replacing RAM in the Upper RAM Slot” if you are replacing RAM in the top RAM slot. • Go to the section “Replacing RAM in the Lower RAM Slot” if you are replacing RAM in the bottom RAM slot. 6 - PowerBook (FireWire) Memory (RAM) Replacing RAM in the Upper RAM Slot After opening the computer (removing the keyboard and heat shield), release the existing RAM expansion card at the two snaps so the card pops up. Then pull the expansion card out of the RAM expansion slot. Warning: When removing or installing the RAM card, do not touch its connectors. Handle the RAM card only by the edges. RAM Expansion Slot PowerBook (FireWire) Memory (RAM) -7 Hold the replacement RAM expansion card at a 30-degree angle. Line up the notch in the card with the small tab in the RAM expansion slot. Then push the RAM expansion card into the expansion slot. Warning: When removing or installing the RAM card, do not touch its connectors. Handle the RAM card only by the edges. 30o Note: You may feel some resistance. If you are having trouble inserting the card, try pu...
