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.

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.

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  
Support. Refer to the About topic under the Do menu for the

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: 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.

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

when you plug in the AC adapter, you need to reset the  
power manager.
