Basics Repair Issues Repair Issues Do Not Remove Heat Exchanger from Microprocessor Board Unless the microprocessor board needs to be replaced, do not separate the heat exchanger from the microprocessor board when taking the PowerBook (FireWire) apart. When the heat exchanger is removed, the phase change material covering the microprocessor chip may need to be removed and replaced. For further information, refer to the Take Apart chapter of this manual.
Basics FireWire New Technologies FireWire FireWire is a high speed serial data bus that can move large amounts of data between computers and peripheral devices. It features simplified cabling, hot swapping, and transfer speeds up to 400 megabits per second (Mbps). FireWire allows users to connect digital consumer products such as digital camcorders, set-top boxes, and music systems directly to the computer. PowerBook (FireWire) is the first of Apple’s portable computers to feature built-in FireWire ports.
Basics AirPort Features PowerBook (FireWire) features include: • PowerPC G3 microprocessor running at clock speeds of 400 or 500 MHz • backside L2 cache of up to 1 MB of fast static RAM • two standard SO-DIMM expansion slots for SDRAM modules and a minimum of 64 MB of SDRAM installed, expandable to 512 MB total • 14.
Basics Drives Drives Module Compatibility Expansion modules used in the PowerBook G3 Series (Bronze Keyboard) may be used in the PowerBook (FireWire), and vice versa. Modules from PowerBook G3 Series computers before PowerBook G3 Series (Bronze Keyboard) are not compatible with the PowerBook (FireWire). Any third-party modules made for PowerBook (FireWire) also may not function properly if used in these earlier PowerBook G3 Series computers.
Basics Memory and Power Memory and Power Sleep Memory Extension 1.0 Apple has identified a very rare issue that may occur when putting a PowerBook (FireWire) to sleep. The computer may be unable to recognize the hard drive at startup. To prevent this from happening, Apple strongly recommends that all PowerBook (FireWire) customers running systems prior to Mac OS 9.0.4 install the Sleep Memory Extension 1.0.
Basics Memory and Power Battery Compatibility The Lithium Ion (LiIon) batteries used for the PowerBook (FireWire) are compatible with those used in the PowerBook G3 Series (Bronze Keyboard) and vice versa. Batteries from earlier PowerBook G3 Series computers are not compatible with PowerBook (FireWire). Battery Level Indicators LiIon batteries have battery level indicator lights that tell whether the battery is fully charged, three-fourths charged, one-half charged, onefourth charged, or empty.
Basics Memory and Power Battery Disposal and Recycling Lithium batteries such as the backup battery in PowerBook (FireWire) require disposal when dead, but you cannot throw them away. In Addition to being potentially explosive, lithium is water reactive, requiring these batteries to be disposed of as hazardous waste. After removing a dead backup battery, clip off the lead wires and place the battery into the zip-lock wrapper that the replacement battery came in.
Basics Sound and Video Sound and Video Sound The PowerBook (FireWire) supports 44.1 kHz 16-bit stereo sound output and input, available simultaneously. Sound output is through either the built-in speakers or the external sound output jack. Sound input can come from: • built-in microphone • external stereo sound input jack • modem slot • CardBus socket • expansion bay device Video The PowerBook (FireWire) 14.
Basics Input and Output Input and Output Keyboard and Trackpad The keyboard and trackpad are the same design as those used in the earlier PowerBook G3 Series of computers. The PowerBook (FireWire) keyboard includes a built-in numeric keypad and controls to adjust display brightness, speaker volume, and external audio port volume. Several of the keys on the keyboard have more than one mode of operation.
Basics Input and Output scanners, and low-speed storage devices. The ports use USB Type A connectors, which have four pins. Ethernet Port The PowerBook (FireWire) has a built-in 10/100 Mbps Ethernet port. When connected to either a 10Base-T or a 100Base-T hub, the port will recognize which type of hub is connected. The connector for the Ethernet port is a short, shielded RJ-45 connector on the back of the computer.
Basics Boards and Cards Boards and Cards General The architecture of the PowerBook (FireWire) is designed around two main circuit boards: the microprocessor board and the I/O logic board. Besides the two main boards, the PowerBook (FireWire) can contain up to seven cards: power supply card, sound card, RAM card (factory installed), RAM card (user installed), AirPort Card, modem, and modem EMI filter. AirPort Card The AirPort Card transmits and receives data at up to 11 Mbps.
Basics Boards and Cards • • • • • find the compatibility information, contact the card vendor. Do not insert anything other than a PC Card into the card slots. The computer must be on or off to eject a PC Card. Do not eject a PC Card when the computer is in sleep mode. Before you eject a card, make sure nothing is blocking the card’s slot. To use the card again immediately, pull it out about an inch more and then push it back in.
