Battery-Handling Guidelines

The following are guidelines for properly handling the
PowerBook 190/5300 Series batteries:

Warning:

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.

NiMH batteries contain toxic materials. Send

Basics Power Information - 11

• 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.

Battery Verification

The Control Strip on the
PowerBook 190/5300
Series desktop indicates the
battery charge and the rate
at which the battery is being
used. To determine the actual
battery charge, use a
voltmeter:

Basics PC Card Handling - 17

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 - 18

• 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.

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:

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).

5 Press the Reset button once and, after a brief pause, the

PowerBook should start up.

If the PowerBook powers off and the sleep display
light stays a solid green with no blinking, press the
Reset button again.

6 If the PowerBook does not power on from the Reset

button, turn the PowerBook on by pressing the Power
key.

7 After the computer has started up, select Shut Down

from the Special menu.

8 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.
