Hot Issues PowerBook 3400: Modem Driver Update - 2

PowerBook 3400: Modem Driver
Update

Issue:

Customers may report one of the following problems

with their PowerBook 3400 modem:

1 The modem will not reset following a disconnect. I

sometimes have to wait 10 to 30 minutes before I can
reconnect to my service provider. Does this happen
because the modem is too hot?

2 When uploading a file using z-modem protocol I often get

multiple errors and my computer freezes or I get a
system error.

3 When I am downloading large files (2-2.5 MB) over the

modem I often get intermittent disconnects.

Hot Issues PowerBook 3400: Modem Driver Update - 3

Solution:

these situations, Apple has released a modem driver update.

Since many users believed these issues were heat-related,
they have had many dealers replace these modems. This
driver should resolve the issues and prevent needless
hardware replacement.

The Modem Driver update is posted at the Apple Software
Updates site. Apple Software Updates can be found on the
Service Source Companion 1 CD, and online as follows:
America Online, CompuServe, ftp.info.apple.com, and
ftp.support.apple.com, www.info.apple.com, and

Issue:

computers have been working loose from their logic board
connections. The customer-reported symptoms related to
this issue include no display image or backlight while the
computer is running.

Solution:

foam gasket to the underside of the brightness and speaker
grill to keep the cable connector in place. In fact, the foam
gasket is not available as a service part and cannot be
ordered separately.

Installation (8/97)

Issue:

A small number of PowerBook 3400 computers
running on battery power have unexpectedly shut down when
jostled or when pressure was applied to the battery area.
The problem is due to intermittent battery contact.

Solution:

Apple recommends adding a foam gasket to the inside of the
battery bay to improve battery contact. The gasket is
available free of charge in a user-installable kit. To order
the kit, customers may call 1-888-273-3594.
Alternatively, service providers may install the gasket for

Basics Product Overview - 1

Product Overview

®

PowerBook 3400c

The PowerBook 3400c
computer is an all-in-one
notebook with several
features that greatly
increase its performance.
Its 603e microprocessor
runs at a clock frequency of
180, 200 or 240 MHz. In
addition to the 256K L2
cache, the PowerBook
3400c comes with 16 MB of
RAM and is upgradeable to
144 MB.

Basics Product Overview - 2

The system includes a 1, 2, or 3 GB hard drive, optional CD­ROM drive, and standard 1.44 MB floppy drive. And, with its

12.1" display, the screen is larger than previous
PowerBook displays.

PowerBook G3

The PowerBook G3 is based on the PowerBook 3400c, but
due to its 250-MHz PowerPC G3 processor, L2 backside
cache, and improved bus speed, the PowerBook G3 is
approximately twice as fast as the 240-MHz PowerBook
3400c. The PowerBook G3 also includes more RAM on
board, a higher powered battery, and a larger hard drive
than the PowerBook 3400c. In addition, the PowerBook G3
is shipping with MacOS 8, which is optimized to run with
the G3 processor. The combination of these features results
in PowerBook G3 break-through performance.

Basics Battery Information - 14

Main Battery

For their main batteries,
the PowerBook 3400c and
G3 use lithium ion (LiIon)
batteries. Each battery
provides power for up to
four hours of work time.

Note

: Although these
batteries fit into a Power­Book 190/5300, it will not
recognize or charge them.

Note:

To use the PowerBook
G3 battery in a PowerBook
3400c, you may need to
install a software update.

Basics Battery Information - 15

Optional Battery

The PowerBook 3400c and G3 computers can also use a
nickel-metal-hydride (NiMH) battery. This battery
provides somewhat less work time; the precise amount of
work time depends on the model you have and the battery
conservation features you use.

Battery Handling Guidelines

The following are guidelines for properly handling the
PowerBook 3400c and G3 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/

LiIon batteries contain hazardous chemicals and

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
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 Card Handling - 17

PC Card Handling

Two PC Card slots (also
known as PCMCIA slots) are
featured in the PowerBook
3400c and G3 computers.

The two slots 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 Type
II cards fit in either the
upper or lower slot of the PC

Basics PC Card Handling - 18

Card unit. Type III cards can only be placed in the lower slot.
When a Type III card is in the lower slot, the upper slot
cannot be used.

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
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.

Basics PC Card Handling - 19

• If you want to use the card again immediately, pull it out
about an inch more 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.
