The RAM Expansion Slot

The iBook computer has one RAM expansion slot. To get access to the RAM expansion slot, the user must open up the computer by performing the following operations.

Important

The user should be reminded to observe the usual precautions to avoid damage to the electronic components due to static electricity.

1. Shut down the computer.
2. Unplug the AC adapter from the computer.
3. Remove the battery from the computer.
4. Unlock the keyboard by turning the slotted screw that is part of the Num Lock LED, which is between the F5 and F6 function keys. Turning the screw 180 locks or unlocks the keyboard. (The locking screw may already be in the unlocked position.)
5. Release the two latches located at the top of the keyboard. One latch is between the ESC key and the F1 key; the other is between the F11 and F12 keys. You can release the latches by sliding them toward the front of the computer. See Figure 3-5.
6. Pulling only on the latches (not on the keys), lift the keyboard up and turn it over, without disconnecting the keyboard's membrane cable.
7. Remove the wireless LAN module, if present, by unlatching the formed wire holder on the module, then pulling the flex tab to remove the module. The antenna cable should remain attached to the module. See Figure 4-1
8. Using a Phillips head screwdriver, remove the two screws that secure the metal RAM shield plate. The screws are to the right of the wireless LAN module. See Figure 4-2.
9. Slide the metal RAM shield plate toward the rear of the computer, then lift it up and out of the computer.
10. On the 14.1-inch model, you must remove the 128-MB SO-DIMM currently occupying the memory expansion slot before installing a larger module.

Once the RAM expansion module has been installed in the slot, the user must close up the computer by performing these steps in reverse order. Be careful to replace the shield plate properly so that the LAN card will fit.

Important

When replacing the keyboard, make sure the latches at the top line up with the corresponding slots in the case.

If AC and battery power are removed for longer than ten minutes, the user may need to reset the computer's clock (using the Data and Time control panel) when the computer is turned back on.
