	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 CD-
	ROM 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 - 9

Battery Information

Warning: For the main battery, use only the lithium-ion (LiIon)battery supplied with the computer. 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 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 - 11

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: 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/

Basics	Battery Information - 12
	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 - 13

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 - 14
	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 - 15
	• 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.
