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.

Battery Information

PowerBook 2400c

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.
