Battery-Handling Guidelines

The following are guidelines for properly handling the

PowerBook 190/5300 Series batteries:

Warning:

NiMH batteries contain toxic materials. Send undamaged, dead batteries to Apple for recycling—do not discard dead batteries with other waste. If battery is damaged, do not return it to Apple. Dispose of damaged batteries according to local ordinances. 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 short-circuit the battery terminals.


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

• Keep the contact cover on the battery when the battery is not in the computer.

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

• Keep the battery in a cool, dark place; do not store it for longer than 6 months without recharging.

• Completely discharge and then recharge the battery once every 90 days.

• Fully charge a replacement battery before using it; Apple ships batteries in a partially charged state.


Nickel-Metal-Hydride

Batteries

The PowerBook 190/5300

Series computers use nickel-metal-hydride

(NiMH) batteries. Each battery provides power for up to 4 hours of work time, depending on the system configuration and battery conservation features employed.

Basics PC Card Handling - 18

PC Card Handling

Two PC Card slots (formerly PCMCIA) are a feature in the

PowerBook 190/5300 Series. The two slots accept a variety of third-party PC Cards.

There are three types of PC Cards: Type I (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 fit in the lower slot and take up both slots.

The following are guidelines for properly handling the PC

Card:

• 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.

Basics PC Card Handling - 19

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

• The PC Card eject button functions regardless of whether the computer is on or off.

• Before ejecting a PC Card, make sure nothing is blocking the slot. To immediately reinsert the card, pull it out an inch or more and then push it back in.

• Eject a PC Card using the PCMCIA Eject control panel or the PCMCIA Quick Eject module in the computer's Control

Strip.

Take Apart Introduction - 1

Introduction

These take-apart procedures are designed for use in two ways: At introduction, read through the entire chapter to train yourself on the complete teardown of the computer; and after you are familiar with the overall process, refer to specific procedures for removal of individual parts.

Take Apart Before You Begin - 2

Before You Begin

The PowerBook 190/5300 Series computers are the most compact and highest performance PowerBooks to date. It follows then that they are also the most intricate to take apart and reassemble. Use the information in this chapter to save time and frustration when disassembling and reassembling these computers.

Tools

Use the following tools for taking apart these computers:

• #8 Torx driver

• 2.3 mm jeweler's screwdriver

• #6 Torx driver (for floppy drive)

• #10 Torx driver (for hard drive bracket)

• #00 jeweler’s screwdriver (for speaker)

Take Apart Before You Begin - 3

Caution

The 190/5300 Series PowerBook computers contain the highest voltage of any PowerBooks. You must

remove the battery and unplug the power adapter before performing any take-apart procedure!

Time-Saving Tips

Use the following information to save time when working on the 190/5300 Series computers.

• Ensure that all cables are routed exactly. Use all grooves and/or protrusions to align cabling. If the cable is improperly routed, you may not be able to reassemble the computer, or once reassembled, the computer may fail to function.

• Check that all cables are properly aligned in the

Take Apart Before You Begin - 4 connectors and that the connections are tight.

• Take note of the type and location of screws in the computer. A variety of screws are used, and it is easy to confuse the type of screw needed in a particular location. If you need to identify a screw, refer to the screw matrix located in the Basics chapter.

Additional Procedures PRAM and Power Manager Reset - 2

PRAM and Power Manager Reset

Caution:

Resetting parameter RAM (PRAM) erases the contents of the RAM disk, if there is one. Resetting PRAM also restores the default settings in most control panels.

After you reset PRAM, be sure to check any custom settings for the desktop pattern, memory, network, AppleTalk, trackpad, power conservation, and so forth.

Resetting PRAM

Reset/zap PRAM from the shutdown state. Note that resetting

PRAM when the computer is shut down also resets the power manager.

Follow these steps to reset PRAM:

1 Unplug the AC adapter.


2 Power on the computer by pressing the Power key.

3 Immediately hold down the Option-Command-P-R keys.

4 Keep holding down these four keys until you have heard the startup chime at least one additional time after the initial startup chime.

(If the PowerBook emits multiple chimes when you are holding down the Option-Command-P-R keys, skip to

Step 7.)

Note:
