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.
Basics
Power Information - 16
• 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.
Basics
Power Information - 17
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.

General
In each product manual on Service Source, you will find
Flowcharts and/or Symptom Charts designed to help you
diagnose and repair Apple computers.
If you have narrowed the problem down to a particular
symptom, start with the Symptom Charts. Because cures are
listed in the order of most likely solution, try the first cure
first. Verify whether or not the product continues to exhibit
the symptom. If the symptom persists, try the next cure.
If you are not sure what the problem is, or if the Symptom
Charts do not resolve the problem, refer to the Flowcharts.
If you require additional assistance, contact Apple Technical

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)

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

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.

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.
Additional Procedures
PRAM and Power Manager Reset - 3
2
Power on the computer by pressing the Power key.
4
Keep holding down these four keys until you have heard
the startup chime at least one additional time after the
initial startup chime.

Immediately hold down the Option-Command-P-R keys.
(If the PowerBook emits multiple chimes when you are
holding down the Option-Command-P-R keys, skip to
Step 7.)
5
Note: Unlike other PowerBook models, these PowerBook
computers often emit only a single startup chime. Then
the screen goes dark/blank and the green sleep light
stays on (it does not blink on and off as it does when the
computer is in sleep mode).
Press the Reset button once and, after a brief pause, the
PowerBook should start up.

If the PowerBook does not power on from the Reset
button, turn the PowerBook on by pressing the Power
key.
After the computer has started up, select Shut Down
from the Special menu.
Plug in the AC adapter. If the computer remains shut
down, you will know that you have successfully reset the
PRAM and power manager and your computer should now
function normally. If, however, the computer powers on
when you plug in the AC adapter, you need to reset the
power manager.
