iBook General Maintenance

Routine work on the PowerPC G3 iBook covers the battery, the memory slot under the keyboard, the clamshell's carrying handle and the parts that age. The procedures are from Apple's Service Source for the clamshell iBook and iBook (FireWire) and Apple's replacement instructions for the iBook (Dual USB).[1][2] Fault-finding is on iBook Troubleshooting.
Tools
[edit | edit source]For the clamshell, Apple lists a coin for the battery door, 5 mm and 4 mm nut drivers, a Torx T8 driver, #0 and #1 Phillips screwdrivers, a very small flat screwdriver for the keyboard lock screw, a non-marring ESD-safe flat tool, an IC extractor for the display cable connector, and fine needle-nose pliers for the handle tension.[1] For the Dual USB, a coin, a #0 Phillips screwdriver and a 2.4 mm flat screwdriver if the keyboard is locked.[2] See Recommended Tools.
Battery
[edit | edit source]- Clamshell: unplug the adapter, turn the two battery door screws a quarter turn to the left with a coin (they pop up but stay captive), lift off the door and pull the battery out by its plastic tab.[1]
- Dual USB: shut down, close the lid, turn the computer over and turn the battery latch a quarter turn clockwise with a coin.[2]
- The clamshell has no backup battery: shut it down, or keep the adapter connected, before taking the battery out.[1]
Original batteries are now almost always dead; some owners rebuild them with new cells.[3] See Battery Refurbishment.
Memory
[edit | edit source]Both designs have memory soldered to the logic board and one SO-DIMM slot under the keyboard, below a RAM shield.[1][2]
- Remove the adapter and battery. On the Dual USB, Apple warns that the internal parts may be hot: wait 30 minutes after use.[2]
- Release the keyboard. On the clamshell, slide the two release tabs left of the F1 and F9 keys towards you; on the Dual USB, pull down the tabs left of the F1 and F12 keys. If the keyboard will not lift, its lock screw beside the Num Lock key is turned: give it half a turn.[1][2]
- Lay the keyboard face down on the palm rest (on a cloth on the clamshell), remove the AirPort Card if fitted, and remove the RAM shield.[1][2]
- Spread the brackets at each side of the old module until it releases. Fit the new one notch to tab at about 30 degrees, push it in and press it down until the brackets lock.[1]
| Model | Soldered | Slot | Maximum |
|---|---|---|---|
| iBook (clamshell) | 32 or 64 MB | 144-pin SDRAM SO-DIMM | 288 or 320 MB (Apple specification page); 160 or 320 MB (Apple Memory Guide)[4][5] |
| iBook (FireWire) | 64 MB | PC100 SO-DIMM, 1.35 in, 3.3 V, up to 256 MB | 320 MB[6] |
| iBook (Dual USB) | 64 or 128 MB | PC-100 SO-DIMM, 1.25 in or shorter, up to 512 MB | 576 or 640 MB[7][2] |
EDO and SGRAM modules fit the slot but are not accepted, and the machine beeps at startup.[5]
Clamshell handle and hinge
[edit | edit source]The handle is part of the display hinge assembly and has a magnesium rod inside it. Owners report hairline cracks in it on all clamshell models, which usually hold together.[3] Taking the display apart releases the handle's spring tension. Apple's procedure for refitting it:[1]
- The left and right clutches have different springs. Fit each spring on its spring shaft so that the cross-wire at the end sits in the slot in the shaft, and put the assembly into the correct end of the handle.
- Grip the flat end of the spring shaft with very thin needle-nose pliers and turn it through 360 degrees in total, using the clutch to hold the tension while you change grip. Slide the clutch on fully and tape the clutch and handle end together.
- Repeat for the other side, then fit the clutches to the display frame with their pins in the frame's holes, refit any grounding strap under its screw, and check the antenna cable routing before closing the display housing.
An owner whose handle would only snap outwards after a rebuild was pointed to Apple's handle-tension material.[8]
Hard disk
[edit | edit source]On the clamshell the hard disk sits under almost everything else; according to owners, the display, top case and optical drive have to come out to reach it.[3][1] See Hard Drive Maintenance and Repair.
Case and cosmetics
[edit | edit source]Common clamshell faults reported by owners: the leaf and apple pieces of the lid logo, which are glued in, falling out; hairline cracks radiating from the Apple logo below the display; cracks between the keyboard and trackpad from stress around a screw standoff; spotty discoloration of the rubber trim; yellowed keyboards; and optical drive door bezels, held by a single screw, knocked off.[3]
