Product Overview - 1

Product Overview

The PowerBook 3400 computers are all-in-one notebooks with several features that greatly increase the performance of PowerBooks. Its 603ev microprocessor runs at a clock frequency of either 180 or 200 MHz. In addition to the 256 KB L2 cache, the PowerBook 3400 comes with 16 MB of RAM and is upgradeable to 144 MB.

Basics	Product Overview - 2
	The system includes a 1 GB or 2 GB hard drive, optional 6x
	CD-ROM drive, and standard 1.44 MB floppy drive. And,
	with its 12.1" display, the screen is larger than previous
	PowerBook displays.

Basics	Battery Information - 9

Battery Information

Warning: For the main battery, use only the lithium-ion (LiIon)battery supplied with the PowerBook 3400, or an identical model. Batteries designed for other portable computers may look similar, but they may not work with your computer and may damage it.

The LiIon and nickel-metal-hydride (NiMH) batteries look similar. To distinguish them,

• Read the label on the battery, which will identify the battery as either “LiIon” or “NiMH.”

• Look for battery indicator lights; if the battery has them, it’s a LiIon battery.

Basics	Battery Information - 10

Main Battery

For its main battery the PowerBook 3400 computers use a lithium ion (LiIon) battery. Each battery provides power for up to four hours of work time, depending on the system configuration and battery conservation features employed.

Note: Although this battery fits into a PowerBook 190/ 5300, the PowerBook 190/ 5300 will not recognize or charge it.

Basics	Battery Information - 11

Optional Battery

The PowerBook 3400 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 3400 batteries:

Warning: LiIon batteries contain hazardous chemicals and 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.

Basics	Battery Information - 12
	• 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.

Battery Matrix

For a matrix of batteries that work with specific models of the PowerBook family of computers, select the PowerBook Battery Matrix located in Hardware/Compatibility Charts.

Basics	PC Card Handling - 14

PC Card Handling

Two PC Card slots (also known as PCMCIA slots) are featured in the PowerBook 3400. 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 Card unit. Type III cards can only be placed in the lower

Basics	PC Card Handling - 15
	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.
	• 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

Basics	PC Card Handling - 16
	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.
