Basics Service Strategy - 3

Service Strategy

At this time, the PowerBook 2400c is sold exclusively in Japan and in the U.S. Therefore, the full line of Apple Service and Support offerings for this product is currently available only in these two countries. Customers wishing to obtain warranty service outside of Japan or the U.S. must deliver the PowerBook 2400c, at their expense, to an Apple Authorized Service Provider in Japan or in the U.S.

Service for the PowerBook 2400c in the U.S. is through Apple central repair. Individual U.S. service providers may, however, upgrade customers’ RAM and replace trackpads and keyboards.

Basics Compatibility - 5

Compatibility

While the PowerBook 2400c offers the compact design of a PowerBook Duo, it does not share the same docking capabilities and is not compatible with any Duo accessory. Instead, the PowerBook 2400c includes a full panel of built-in ports for easy connectivity without the need for a Dock.

The PowerBook 2400c uses an external floppy drive that is not compatible with previously released PowerBooks, due to its unique connector. The floppy drive also employs a unique, removable cable.

Technology

PowerPC 603ev

The PowerPC 603ev chip that is the CPU in the PowerBook 2400c is the same as the CPU on the PowerBook 3400c logic board and includes a built-in cache of 32K (16K data and 16K instructions). The 603ev chip executes commands by reading from ROM, writing to RAM, and communicating with the I/O (input/output) via the PSX chip, and then outputs to the video controller for display on the screen.

Level 2 Cache

To complement the Power PC 603ev processor, the PowerBook 2400c implements 256K of level 2 (L2) cache. Level 2 cache assists the processor by storing frequently

Basics Technology - 9

accessed instructions in the cache where they can be read quickly, thus freeing up the processor to move onto the next set of instructions.

ROM

The 4 MB of ROM in the PowerBook 2400c is based on the ROM used in the PowerBook 3400c. It includes the DR emulator, which allows older 68K applications to run on the computer. The ROM data path is 64-bits wide.

RAM

The PowerBook 2400c includes 16 MB of EDO DRAM located on the logic board. Service providers can also populate the computer’s one expansion slot with either a 16 MB or 32 MB EDO RAM card from a third-party RAM vendor. The RAM

Basics Technology - 10

is low power self-refreshing with a 70 ns access time. The RAM data path is 64-bits wide.

PCI Architecture

The PowerBook 2400c, like the PowerBook 3400, incorporates PCI architecture with an internal 32-bit wide data path. PCI is an industry-standard technology and features a 33 MHz system bus and a 40 MHz I/O bus.

Video Controller

The video component of the PowerBook 2400c is a Chips and Technology 65550 PCI video controller. This highperformance video controller noticeably speeds up simple tasks, such as window scrolling and line draws, and provides a significant boost in high-end video. Two-dimensional

Basics Technology - 11

hardware acceleration provides quick video mirroring to an external monitor in presentation mode and boosts the speed of QuickTime video to a fast and smooth frame rate.

10.4" TFT LCD Display

The PowerBook 2400c includes a 10.4" (measured diagonally) TFT (active-matrix) LCD panel with 800 x 600 resolution. This LCD is a fixed SVGA resolution panel capable of displaying thousands of colors but does not support 1-bit resolution (black and white), as the PowerBook 3400c does. The 16-bit video-out port makes it easy to hook up external monitors as large as 20 inches in 8-bit mode or external projectors for making large-screen presentations.

Basics Technology - 12

Trackpad

As with the PowerBook 1400 and 3400 series, the built-in trackpad is tap, double-tap, and drag-capable. This PowerBook is also the first to offer an inverted "T" on the keyboard, making it easier to navigate through spreadsheets and word documents.

Zoom Video

The PowerBook 2400c supports zoom video, a newly formed standard, and allows input from an MPEG, TV tuner, or video-capture PC card. The resulting video on the screen is a 24-bit, 30 fps, 640x480 image. Customers can also use a video camera or videoconferencing camera to conference with other users across the Internet.

2400c lithium-ion (Lilon) main battery in their computers. Batteries designed for other portable computers, such as the nickel-metal-hydride (NiMH) batteries or the Lilon battery for the PowerBook 3400c, may look similar, but they do not work with the PowerBook 2400c.

Each PowerBook 2400c battery provides power for between 2 and 4 hours of work time, depending on the system configuration and battery conservation features employed.

Battery Handling Guidelines

The following are guidelines for properly handling PowerBook 2400c batteries:

Warning:

should not be thrown out with household or office trash. Take dead batteries to an Apple authorized service provider for recycling or proper disposal. Review battery handling and disposal instructions in Safety Information in Bulletins/ Safety.

• Handle the battery carefully. Do not drop, puncture, disassemble, mutilate, or incinerate it.

• Do not leave a battery in the computer for longer than a week without plugging in the power adapter.

• Always put the battery cap on the battery when the battery is out of the PowerBook. The battery contacts should not be exposed when the battery is out of the

LiIon batteries contain hazardous chemicals and

Basics Battery Information - 15

computer.

• Do not leave the battery in hot locations (such as the trunk of a car).

• Do not leave a battery in storage for longer than six months without recharging it.

• Never get batteries wet.

• Do not short-circuit the battery terminals. Doing so may cause an explosion or a fire.

• Recharge batteries only as described in the user’s manual and only in ventilated areas.

Basics PC Cards - 16

PC Cards

The PowerBook 2400c includes two PC card slots, which accept a variety of third-party PC cards with 68-pin connectors.

There are three types of PC cards: Type I (3.3 mm), Type II (5 mm), and Type III (10.5 mm). Type I and II cards fit in either the upper or lower PC card slot. Type III cards can only be used in the lower slot and when in place do not allow the upper slot to be used.

PC Card Handling

The following are guidelines for properly handling PC cards:

• Use only cards that are compatible with the PC card unit. Refer to the compatibility information that came with the

Basics PC Cards - 17

card. If you cannot find the compatibility information, call the card vendor.

• Do not insert anything other than a PC card into the card slots.

• The computer must be on or off in order to eject a PC card. When the computer is in sleep mode, a PC card cannot be ejected.

• Before you eject a card, make sure nothing is blocking the card’s slot.

• If you want to use the card again immediately, pull it out about 2 inches and then push it back in. If you don’t follow this procedure and try to push the card back in to use it again, the card will not engage properly.

• Do not pull on a PC card before it has been ejected out of the slot. Forcing a PC card out of the slot may damage the computer or the card.
