5 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 th e keyboard. If these keys are improperly removed or installed, the ke yboard may not func tion properly .
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.

7 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.
There is no sound or sound volume is t oo low. Cause Solution System volume may be set low or muted. 1. Check the F10 BIOS settings to make sure the inte rnal system speaker is not muted (this setting doe s not affect the external speakers).
Computer powe red off automa tically and the Pow er LED flashes Red two times, onc e every second, followed by a two second pause, an d the computer beep s two times. (Beep s stop after fifth iterat ion but LEDs continue flashing). Cause Solution Processor thermal protection activated: A fan may be blocked or not turning.
Solving power problems Common causes and so lutions for po wer problems are listed in the f ollowing table. Table 7-2 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 Erro r- checking click Check Now .
Table 7-3 Solving ha rd drive problems (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. Cause Solution The operating system needs time to recog nize the device if the reader was just installed into the computer and you are turning the PC on for the first time.
Blank screen and the power L ED flashes red six times, o nce every second, followed b y a two second pause, a nd the computer beeps six times. (Beeps stop af ter fifth iteration bu t LEDs continue f lashing.) Cause Solution Pre-video graphics error . For systems with a graphics car d: 1.
Table 7-5 Solving di splay problem s (continued) Fuzzy focus; streaking, ghosting, or shadowing effects; horizontal scrolling lines; faint vertical bars; or unable to center the picture o n the screen (flat pa nel m onitors using an an alog VGA input c onnection only).
