5 Identifying the Chassis, 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.
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.

C 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 C -2 Solving Power 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.
Solving Diskette Problems Common causes and so lutions for diskett e problems are listed in the f ollowing table. NOTE: The computer does not sup port internal di skette drives. Only USB diskette d rives are supported. NOTE: You may need to reconfi gure the computer wh en you add or remove h ardware, such as an additional di skette drive.
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.
Table C -3 Solving Diskette Problems (continued) Cannot Boot to Diskette. Cause Solution Diskette boot has been disabled in Computer Setup. 1. Ru n Computer Setup and enable USB device in Storage > Boot Order . 2. Run Computer Setup and enable USB device in Storage > Storage Options > Removable Media Boot .
Table C -4 Solving Hard Drive Problems (continued) Drive not found (iden tified). Cause Solution The system may not have automatically recog nized a newly installed device. See reconfiguration directions in the Solving Hardware Installation Problems on page 117 section.
Computer will not boot from hard drive. Cause Solution The device is attached to a SATA port that has been hidden in Computer Setup. Run the Computer Setup utility and ensure Device Ava ilabl e is selected for the device's SATA port in Sec urity > Device Security .
Solving Media Card Reader Problems Table C -5 Solvi ng Media Ca rd Reader Pr oblems A write-protected or locked error occurs when attempting to write to the media card. Cause Solution Media card is locked. Locking the media card is a safety feature that prevents writing to and deleting from an SD/ Memory Stick/PRO card.
After inserting a med ia card in the reader, the c omputer attempts to boot from the media c ard. Cause Solution The inserted media card has boot ca pability. If you do not want to boot from the media card, remove it during boot or do not select the option to boot from the inserted media card during the boot proce ss.
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.
The picture is broken up, rolls, jitters, or flashes. Cause Solution The monitor connections may be incomplete or the monitor may be incorrectly adjusted. 1. In a two-monitor system or if another monitor is in close proximity, be sure the monitors are not in terfering with each other’s electromagnet ic field by moving them apart.
Certain typed symb ols do not appear correct. Cause Solution The font you are using does not suppo rt that particular symbol. Use the Character Map to locate and select the appr opriate symbol. Click Start > All Programs > Accessories > System Tools > Character Map .
Solving Audio Problems If the computer ha s audio features a nd you enco unter audio problems, see the common cau ses and solutions listed in the foll owing table. Table C -7 Solving Audio Problems Sound cuts in and o ut. Cause Solution Processor resources are being used by other open applications.
Table C -7 Solving Audio Problems (continued) Sound does not come out of the speaker o r headphones. Cause Solution Some applications can select which audio output device is used.
Solving Printer Problems If you encounte r printer problems, see the documentation that ca me with the printer an d to the common causes and solutions listed in the following table. Table C -8 Solving Pr inte r Problems Printer will not print. Cause Solution Printer is not turned on and o nline.
Table C -9 Solving Keyboard Problems Keyboard commands and typing are not re cognized by the computer. Cause Solution Keyboard connector is not proper ly connected. 1. Click Start , click the arrow on the lower right corner of the Start menu, then select Shut Down .
Table C-10 Solving Mous e Problems (con tinued) Mouse does not respond to movement or is too slow. Cause Solution Mouse may need repair. See the Worldwide Limited Warranty for terms and conditions. Computer is in standby mode. Press the power button to resume fro m standby mode.
Solving Hardware Installation Problems You may need to reconfigure the compu ter when you add or remove hardware, such as an addi tional drive or expansion card. If you install a plug an d play device, Windows auto matically recognizes the device and configures the computer.
Power LED flashes red five times, once every second , followed by a two s econd pause, and the c omputer beeps five times. (Beeps s top after fifth itera tion but LEDs con tinue flashing.
Table C-12 Solving Network Prob lems Wake-on-LAN featu re is not functioning. Cause Solution S5 Maximum Power Saving feature is enabled. Disable the S5 Maximum Power Saving option in Computer Setup. Select Power > Hardware Power Management > S5 Maximum Power Saving .
Diagnostics reports a failure. Cause Solution The cable is not secur ely connected. Ensure that the cable is securely attached to the network connector and that the other end of the cable is secure ly attached to the correct device. The cable is attached to the in correct connector.
