Basics	PCMCIA Module Handling - 10

PCMCIA Module Handling

The PCMCIA (Personal Computer Memory Card International Association) expansion module is an option for the PowerBook 500 Series. The module inserts into the computer’s second (left) battery bay and has two slots that accept a variety of third-party PCMCIA cards.

There are three types of PCMCIA cards: Type I (3 mm), Type II (5 mm), and Type III (10 mm). Type I and Type II cards fit in either the upper or lower slot of the expansion module. Type III cards fit in the lower slot and take up both slots.

The following are guidelines for properly handling the PCMCIA expansion module:

• Do not insert or remove the PCMCIA expansion module while the computer is on or in Sleep mode. if you do, the

Basics	PCMCIA Module Handling - 11
	computer will shut down and all RAM contents will be
	lost.
	• Eject the PCMCIA module using the lever at the front of
	the module; eject a PCMCIA card using the PCMCIA Eject
	control panel or the PCMCIA Quick Eject module in the
	computer’s Control Strip.
	• Keep the protective cap that comes with the module and
	place it back on the module when it is not in use.
	• Do not open the module or insert anything other than a
	PCMCIA card into the card slots.
	• Keep the module in a safe place, away from small objects
	that might fall into it.
	• Before ejecting a PCMCIA card, make sure nothing is
	blocking the card’s slot. To immediately reinsert the
	card, pull it out an inch more and then push it back in.
	• Use only cards that are compatible with the PCMCIA
	expansion module. Refer to the compatibility
	information that came with the card.

Basics	Battery Information - 12

Battery Information

The PowerBook 500 Series computers include one or two nickel-metal-hydride (NiMH) batteries. Each battery provides power for up to 3.5 hours of work time, depending on the battery conservation features employed. A smart processor included in each battery pack indicates the battery’s charge status.

For instructions on how to verify the battery voltage, see the Additional Procedures chapter of this manual.

For additional information on PowerBook batteries, voltages, ampere hours, and part numbers, see the PowerBook Battery Matrix in Hardware/Compatibility Charts.

Basics	Battery Information - 13

Battery Handling

±Warning: NiMH batteries contain toxic materials. Send undamaged, dead batteries to Apple for recycling—do not discard dead batteries with other waste. If the battery is damaged, do not return it to Apple. Dispose of damaged batteries according to local ordinances. Review batteryhandling and disposal instructions in the Safety document (path: Bulletins/Safety).

The following are guidelines for properly handling the

PowerBook 500 Series battery:

• 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.

• Do not leave the battery in hot locations (such as the

Basics	Battery Information - 14
	trunk of a car).
•	Keep the battery in a cool, dark place; do not store it for
	longer than 6 months without recharging.
• If you are using one battery: completely discharge and
	then recharge the battery once every 90 days.
•	If you are using two batteries: swap the left and right

batteries every month.

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