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.
● Never cover the vent ilation slots on th e monitor with any type of material. ● Install or enable power managemen t functions of the operating system or other software, including sleep s tates. Routine Care General Cleaning Safety Precautions 1.
CAUTION: Use safety glasses equipped with side sh ields before attempti ng to clean debris from under the keys. ● Visible debris undern eath or between th e ke ys may b e removed by vacuuming or shakin g. ● Canned, pressuri zed air may be used to clean debri s from under the keys.
Tools and Software Requirements To service the co mputer, you need the fo llowing: ● Torx T-15 screwdriver (HP screwd river with b its, PN 161946-0 01) ● Torx T-15 screwdriver with small diameter .
● Before handling a drive, ensure th at you are di scharged of static electricity. While hand ling a drive, avoid touching the connector. F or more information about pre venting electrosta tic damage, refer to Electrostati c Discharge Information on page 20 ● Do not use exc essive force when inse rting a drive.

Table B -2 Diagnostic Front Panel LEDs and Audible Codes (co ntinued) Activity Blinks Possible Cause Recommended Action Red Power LED flashes four times, once every second, followed by a two second pause. Beeps stop after fifth iteration but LEDs continue until problem is solved.
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.
● Boot the computer to the Safe Mode to see if it wil l boot withou t all of the drivers loaded. When booting the o perating system, use “La st Known Configuration.” ● Refer to the comprehensive online tech nical support at http://www.hp.com/ support .
● Press and hold any key. If the system be eps, then the keyboard should be operating correc tly. ● Check all cable connections for lo ose connections or inco rrect connections. ● Wake the computer by pressing an y key on the keybo ard or pressing the power button .
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 internal system speaker is not muted (this setting doe s not affect the external speakers).
Table C -1 Solving General Pro blems (continued ) Poor performance is experienced. Cause Solution Too many applications running. 1. Close unnecessary applications to free up memory. 2. Add more memory. Some applications run in the background and can be closed by right-clicking on the ir corresponding icons in the task tra y.
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 C -2 Solving Power Problems Power supply shuts down intermittent ly. Cause Solution Voltage selector switch on rear of computer chassis (some models) not switched to correct line voltage (1 15V or 230V).
Power LED flashes Re d four times, onc e every second, follow ed by a two sec ond pause, and the co mputer beeps four times. (Beeps stop after fifth it eration but LEDs co ntinue flashing.) Cause Solution Power failure (power supply is overload ed). 1.
Solving Hard Drive Problems Table C -3 Solving Hard Drive Problems Hard drive error occurs. Cause Solution Hard disk has bad sectors or has failed. 1. In Microsoft Windows XP, right-click Start , click Explore , and select a drive. Select File > Properties > Tools .
Nonsystem disk/NTLDR missing message. Cause Solution The system is trying to start from a diskette that is not bootable. Remove the diskette from the diskette drive. The system is trying to start from the hard drive but the ha rd drive may have been damaged.
Computer seems to be loc ked up. Cause Solution Program in use has stopped responding to comma nds. Atte mpt the normal Windows “Shu t Down” procedure. If this fails, press the power button for four or more seconds to turn off the power. To restart the compu ter, press the power button again.
Solving Media Card Reader Problems Table C -4 Solvi ng Media Ca rd Reader Pr oblems Media card will not work in a digital camer a after formatting it in Microsoft Windows. Cause Solution By default, Windows will format any media card with a capacity greater than 32MB with the FAT3 2 format.
Do not know how t o remove a media card correctly. Cause Solution The computer’s software is used to safely eject the card. Open My Computer (Windows XP), Computer (Windows Vista), or Devices and Printers (Windows 7), r ight-click on the corresponding drive icon, and select Eject .
Solving Display Problems If you encounte r display problems, see the do cumentation that came with the monitor a nd to the common causes and solutions listed in the following table. Table C -5 Solving Display Problem s Blank screen (no video ). Cause Solution Monitor is not turned on and the monitor light is not on.
Cannot enable integr ated graphics after insta lling a PCI Express graphics card. Cause Solution On systems with Intel integrated graphics, the integrated graphics cannot be enabled after installing a PCI Express x16.
Dim characters. Cause Solution The brightness and contrast controls are not set pr operly . Adjust the monitor brightne ss and contrast controls. Cables are not properly co nnected. Check that the graphics cable is securely connecte d to the graphics card and the monitor.
