6 Routine Care and Disassembly Preparation This chapter provides general service information for the computer. Ad herence to th e procedures and precautions described in this chapter is esse ntial for proper service. CAUTION: When the computer is plugged in to an AC power source, voltage is always applied to the system board.
Electrostatic discharge information A sudden discharge of static electricity f rom your fi nger or other conductor ca n destroy static-sensitive devices or microcircuitry.
● Always be properly ground ed when touching a sen sitive component o r assembly. ● Avoid contact with pins, lea ds, or circuitry. ● Place reusable electrostatic- sensitive parts fro m assemblie s in protective p ackaging or conductive foam.
● Conductive bi ns and other as sembly or soldering ai ds ● Conductive foam ● Conductive tabletop workstations with ground cord of one-meg ohm +/- 10% resistance ● Static-di ssipativ e table o.
Routine Care General cleaning safety precautions 1. Never use solven ts or flammable solutio ns to clean the computer. 2. Never immerse any parts in water or cleaning solutions; app ly any liquids to a cl ean cloth and then use the cloth on the componen t.
● If you remove a key, use a sp ecially designed key puller to prevent dama ge to the keys. This tool is availabl e through many electron ic supply outlets. CAUTION: Never remove a wide leveled key (like th e space bar) from the keyboard. If these keys are improperly removed or instal led, the keyboard may not fu nction proper ly.
Cables and connectors Most cables used throu ghout the unit are flat, fl exible cables. Th ese cables must be handled with care to avoid damage. Apply onl y the tension required to sea t or unseat the cables during insertion or removal from the conne ctor.

8 Troubleshooting Without Diagnostics This chapter provide s information on how to i denti fy and correct minor problems, such as diskette drive, hard drive, optical drive, gra phics, audio, memory, and software problems.
Solving general problems You may be able to easily resolve the g eneral pr obl ems described in this section . If a problem persists and you are unable to resolv e it yourself or if you fe el uncomfortable ab out performing the operation, contact an authorized dealer or reseller.
Computer date and t ime display is incorrect. Cause Solution RTC (real-time clock) battery may need to be replaced. NOTE: Connecting the computer to a live AC outlet prolongs the life of the RTC batter y. First, reset the date and time under C ontrol Panel (Computer Setup can also be used to update the RTC date and time).
Table 8-1 Solv ing general problems (continued) Poor performance is experienced. Cause Solution Virus resident on the hard drive. Run virus protection progr am. Too many applications running. 1. Close unnecessary applications to free up memory. 2. Add more memory.
System does not power on an d the LEDs on the front of the computer are not flashing. Cause Solution System unable to power on. Press and hold the power button for less than 4 seconds.
Solving power problems Common causes and so lutions for po wer problems are listed in the f ollowing table. Table 8-2 Solving po wer problems Computer powered o ff automatically and t he Power LED flashes red t wo times, once every second, followed b y a two second pause, an d the computer beep s two times.
Disk transaction problem. Cause Solution Either the directory structure is bad or there is a problem with a file. Right-click Start , click Explore , and right-click on a drive. Select Properties then se lect the Tools tab. Under Error- checking click Check Now .
Table 8-3 Solving ha rd drive proble ms (continued) Nonsystem disk/NTLDR missing message. Cause Solution Bootable hard drive is not attached as first in a multi-hard drive configuration. If attempting to boot from a hard drive, ensur e it is attached to the system board dark blue SATA conn ector.
The removable hard drive enclosure is bee ping and the green LED is flashing. Cause Solution Fan failure alarm on the removable hard drive enclosure has been activated.
After installing the media card reader and booting to Wind ows, t he reader and the in serted cards are not recognized by the computer.
