Battery-Handling Guidelines

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

Warning: NiMH batteries contain toxic materials. Sendundamaged, dead batteries to Apple for recyclingdo notdiscard dead batteries with other waste. If battery isdamaged, do not return it to Apple. Dispose of damagedbatteries according to local ordinances. Review batteryhandling and disposal instructions in Safety Information inBulletins/Safety.

Handle the battery carefully. Do not drop, puncture,

disassemble, mutilate, or incinerate it. Do not short-circuit the battery terminals.


18/186


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

Keep the contact cover on the battery when the battery isnot in the computer.

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

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

Completely discharge and then recharge the battery onceevery 90 days.

Fully charge a replacement battery before using it; Appleships batteries in a partially charged state.


19/186


Nickel-Metal-HydrideBatteries

The PowerBook 190/5300Series computers use

nickel-metal-hydride(NiMH) batteries. Eachbattery provides power forup to 4 hours of work time,depending on the systemconfiguration and batteryconservation featuresemployed.


20/186

Basics PC Card Handling - 18

PC Card HandlingTwo PC Card slots (formerly PCMCIA) are a feature in thePowerBook 190/5300 Series. The two slots accept a varietyof 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 cardsfit 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 PCCard:

Use only cards that are compatible with the PC Card unit.Refer to the compatibility information that came with thecard. If you cannot find the compatibility information,call the card vendor.


21/186

Basics PC Card Handling - 19

Do not insert anything other than a PC Card into the cardslots.

The PC Card eject button functions regardless of whetherthe computer is on or off.

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

Eject a PC Card using the PCMCIA Eject control panel orthe PCMCIA Quick Eject module in the computer's ControlStrip.

Take Apart Introduction - 1

IntroductionThese take-apart procedures are designed for use in twoways: At introduction, read through the entire chapter totrain yourself on the complete teardown of the computer;

and after you are familiar with the overall process, refer tospecific procedures for removal of individual parts.


74/186

Take Apart Before You Begin - 2

Before You BeginThe PowerBook 190/5300 Series computers are the mostcompact and highest performance PowerBooks to date. Itfollows then that they are also the most intricate to take

apart and reassemble. Use the information in this chapter tosave time and frustration when disassembling andreassembling 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 jewelers screwdriver (for speaker)


75/186


Caution

The 190/5300 Series PowerBook computers contain thehighest voltage of any PowerBooks. You must remove thebattery and unplug the power adapter before performing anytake-apart procedure!

Time-Saving Tips

Use the following information to save time when working onthe 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 toreassemble the computer, or once reassembled, thecomputer may fail to function.

Check that all cables are properly aligned in the


76/186


connectors and that the connections are tight.

Take note of the type and location of screws in thecomputer. A variety of screws are used, and it is easyto confuse the type of screw needed in a particularlocation. If you need to identify a screw, refer to thescrew matrix located in the Basics chapter.
