6 Identifying the Chassis, Routine Care, and Disassembly Preparation This chapter provides gen eral service information for the computer. Adherence to the procedures and precautions describ ed in this chap ter is essential for proper service.
Electrostatic Discharge Information A sudden discha rge of static electrici ty from your finger or other cond uctor can destroy static-sensitive devices or microcircuitry.
● Avoid contact with pins, leads, or circuitry. ● Place reusable electrostatic-sensit ive parts from assemblies in pro tective packaging or conductive foam.
● Conductive foam ● Conductive tabletop workstat ions with ground cord of one-megohm +/- 10% resistance ● Static-dissipative tab le or floor mats with hard tie to ground ● Field service kits .
Operating Guidelines To prevent ov erheating and to help prolong the life of the computer: ● Keep the computer away from excessive moisture, direct su nlight, and extremes of h eat and cold. ● Operate the computer on a sturdy, level surface. Leave a 10.
To clean the comput er case, follow the procedures described below: ● To remove light stains or dirt, use plain water with a clean, lin t-free cloth or swab. ● For stronger stains, use a mild d ishwashing liquid diluted with water. Rinse well by wiping it with a cloth or swab dampened with cle ar water.
Cleaning the Mouse Before cleanin g the mouse, ensure that the power to the compu ter is turned off. ● Clean the mouse ball by first removing the retaining plate a nd the ball from the housing. Pull out any debris from the b all socket and wipe the ba ll with a clean, dry cloth be fore reassembly.
Cables and Connectors Most cables used throug hout the unit are flat, flexible cables. These cables must be handled with care to avoid damage . Apply only the ten sion required to seat or un seat the cables during insertion or remova l from the connecto r.

D Troubleshooting Without Diagnostics This chapter provid es information on how to identify and correct minor problems, such as diskette drive, hard drive, opt ical drive, graphics, au dio, memory , and software problems.
● If you recently installed new software, uninstal l the software and see if th e computer fu nctions properly. ● Boot the computer to the Safe Mode to see if it wi ll boot without all of the drivers lo aded. When booting the operating system, us e “Last Kn own Configuration.
● Press and hold any ke y. If the system beeps, then the keyb oard should be operating correctly. ● Check all cable connections for loose connections or incorrect connections. ● Wake the computer by pressing any key on the key board or pressing the power button.
Solving General Problems You may be able to easily resolve the genera l problem s described in this section. If a problem persi sts and you are unable to resolve it yourself or if you feel uncomfor table about performing the operati on, contact an authorized dealer or reseller.
Cursor will not move using the arrow keys on the keypad . Cause Solution The Num Lock key may be on. Press the Num Lo ck key. The Num Lock light should not be on if you want to use the arrow keys. The Num Lock key can be disabled (or enabled) in Computer Se tup.
Poor performance is experienced. Cause Solution Too many applications running. 1. Close unnecessary applications to free u p memory. Some applications run in the background and can be closed by right-clicking on t heir correspond ing icons in the task tray.
System does not power on and the LEDs on the front of the c omputer are not flas hing. Cause Solution OR Press and hold the power button for less than 4 seconds. If the hard drive LED does not turn on green then: 1. Check that the unit is plugged into a w orking AC outlet.
Solving Power Problems Common causes and solutions for power pro b lems are liste d in the following ta ble. Table D-2 Solving Power Problems Power supply shuts down intermitt ently. Cause Solution Voltage selector switch on rear of computer chassis ( some models) not switched to correct line vo ltage (115V or 230V).
Solving Diskette Problems Common causes and solutio ns for diskette prob lems are l isted in the follo wing table. NOTE: You may need to reconfi gure the compu ter when you add or remove hardware, such as an additional diskette drive. See Solving Hardware In stallation Problems on page 137 for instructions.
Cannot format diskette. Cause Solution Invalid media reported. When formatting a disk in MS-DOS, you may need to specify diskette capacity. For example, to format a 1.44-MB diskette, type the following command at the MS-DOS prompt: FORMAT A: /F:1440 Disk may be write-protected.
