Page 37: Unsupported Usb Flash Media Device
CAUTION: If a drive does not match the USB flash media device, do not proceed. Data loss can occur. Check all USB ports for additional storage devices. If any are found, remove them, reboot the computer, and proceed from step 4. If none are found, either the system does not support the USB flash media device or the USB flash media device is defective.
Page 38 CAUTION: Some older PCs may not be bootable from a USB flash media device. If the default boot order in the Computer Setup (F10) Utility lists the USB device before the hard drive, the computer can be booted from a USB flash media device. Otherwise, a bootable diskette must be used. If there are any PCI cards in the system that have SCSI, ATA RAID or SATA drives attached, turn off the computer and unplug the power cord.
Page 39: Dual-State Power Button
NOTE: The default boot order varies from computer to computer, and it can be changed in the Computer Setup (F10) Utility. Refer to the Computer Setup (F10) Utility for instructions. If you have used a DOS version from Windows 9x, you may see a brief Windows logo screen. If you do not want this screen, add a zero-length file named LOGO.SYS to the root directory of the USB flash media device.

Page 47: Identifying The Chassis, Routine Care, And Disassembly Preparation
Identifying the Chassis, Routine Care, and Disassembly Preparation This chapter provides general service information for the computer. Adherence to the procedures and precautions described in this chapter is essential for proper service. CAUTION: When the computer is plugged into an AC power source, voltage is always applied to the system board.
Page 48: Small Form Factor (Sff)
Small Form Factor (SFF) NOTE: The appearance of the front bezel may vary. Electrostatic Discharge Information A sudden discharge of static electricity from your finger or other conductor can destroy static-sensitive devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An electronic device exposed to electrostatic discharge (ESD) may not appear to be affected at all and can work perfectly throughout a normal cycle.

Page 51: Operating Guidelines
Operating Guidelines To prevent overheating and to help prolong the life of the computer: ● Keep the computer away from excessive moisture, direct sunlight, and extremes of heat and cold. ● Operate the computer on a sturdy, level surface. Leave a 10.2-cm (4-inch) clearance on all vented sides of the computer and above the monitor to permit the required airflow.
Page 52: Routine Care
Routine Care General Cleaning Safety Precautions Never use solvents or flammable solutions to clean the computer. Never immerse any parts in water or cleaning solutions; apply any liquids to a clean cloth and then use the cloth on the component. Always unplug the computer when cleaning with liquids or damp cloths.
Page 53: Cleaning The Monitor
● If you remove a key, use a specially designed key puller to prevent damage to the keys. This tool is available through many electronic supply outlets. CAUTION: Never remove a wide leveled key (like the space bar) from the keyboard. If these keys are improperly removed or installed, the keyboard may not function properly.
Page 54: Screws
Screws The screws used in the computer are not interchangeable. They may have standard or metric threads and may be of different lengths. If an incorrect screw is used during the reassembly process, it can damage the unit. HP strongly recommends that all screws removed during disassembly be kept with the part that was removed, then returned to their proper locations.
Page 55 WARNING! This computer contains a lithium battery. There is a risk of fire and chemical burn if the battery is handled improperly. Do not disassemble, crush, puncture, short external contacts, dispose in water or fire, or expose it to temperatures higher than 140ºF (60ºC). Do not attempt to recharge the battery.

Bezel Blanks On some models, there are bezel blanks covering the 3.5-inch and 5.25-inch external drive bays that need to be removed before installing a drive. To remove a bezel blank: Follow the instructions described in Front Bezel on page Press the two retaining tabs towards the outer left edge of the bezel (1) and pull the bezel blank inwards to remove it (2).
Page 61: Memory
Memory The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2- SDRAM) dual inline memory modules (DIMMs). CAUTION: DDR and DDR2 memory modules are not interchangeable. DDR2-SDRAM DIMMs The memory sockets on the system board can be populated with up to four industry-standard DIMMs. These memory sockets are populated with at least one preinstalled DIMM.
Page 62: Populating Dimm Sockets
Populating DIMM Sockets There are four DIMM sockets on the system board, with two sockets per channel. The sockets are labeled DIMM1, DIMM2, DIMM3, and DIMM4. Sockets DIMM1 and DIMM2 operate in memory channel A. Sockets DIMM3 and DIMM4 operate in memory channel B. Figure 7-5 DIMM Socket Locations Table 7-1...
Page 63: Installing Memory Modules
with the least amount of memory describes the total amount of memory assigned to dual channel and the remainder is assigned to single channel. For optimal speed, the channels should be balanced so that the largest amount of memory is spread between the two channels. If one channel will have more memory than the other, the larger amount should be assigned to Channel A.
Page 64 Open both latches of the memory module socket (1), and insert the memory module into the socket (2). Figure 7-6 Installing a DIMM NOTE: A memory module can be installed in only one way. Match the notch on the module with the tab on the memory socket.

Be sure not to scrape the card against the other components. Figure 7-10 Removing a PCI Express x1 Expansion Card If you are removing a PCI Express x16 card, pull the retention arm on the back of the expansion...
Page 68 If you are not installing a new expansion card, install an expansion slot cover to close the open slot. CAUTION: After removing an expansion card, you must replace it with a new card or expansion slot cover for proper cooling of internal components during operation. To install a new expansion card, hold the card just above the expansion socket on the system board then move the card toward the rear of the chassis so that the bottom of the bracket on the card slides into the small slot on the chassis.
Page 69: Cable Management
Connect external cables to the installed card, if needed. Connect internal cables to the system board, if needed. Replace the computer access panel. Reconnect the power cord and any external devices, then turn on the computer. Lock any security devices that were disengaged when the access panel was removed. Reconfigure the computer, if necessary.
