Serviceability Features

The Microtower computer includes features that make it easy to upgrade and service. A Torx T-15 screwdriver is needed for many of the installation procedures described in this chapter.

Warnings and Cautions

Before performing upgrades be sure to carefully read all of the applicable instructions, cautions, and warnings in this guide.

Å WARNING: To reduce the risk of personal injury from electrical shock and/or hot surfaces, be sure to disconnect the power cord from the wall outlet and allow the internal system components to cool before touching.

Å WARNING: To reduce the risk of electrical shock, fire, or damage to the equipment, do not plug telecommunications/telephone connectors into the network interface controller (NIC) receptacles.

Ä CAUTION: Static electricity can damage the electrical components of the computer or optional equipment. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a

grounded metal object. See Chapter 4, “Electrostatic Discharge”

for more information.

Ä CAUTION: When the computer is plugged into an AC power source, voltage is always applied to the system board. You must disconnect the power cord from the power source before opening the computer to prevent system board damage.

Installing Additional Memory

The computer comes with double data rate 2 synchronous dynamic random access memory (DDR2-SDRAM) dual inline memory modules (DIMMs).

DIMMs

The memory sockets on the system board can be populated with up to two industry-standard DIMMs. These memory sockets are populated with at least one preinstalled DIMM. The sockets are labeled DIMM1 and DIMM2. To achieve the maximum memory support, you can populate the system board with up to 2GB (2 x 1GB) of memory.

DDR2-SDRAM DIMMs

For proper system operation, the DDR2-SDRAM DIMMs must be:

■

■ industry-standard 240-pin unbuffered PC2-5300 667 MHz-compliant

1.9 volt DDR2-SDRAM DIMMs

The DDR2-SDRAM DIMMs must also:

■

■ support CAS latency 4 (CL = 4) for PC2-5300 667 MHz contain the mandatory JEDEC SPD information

In addition, the computer supports:

■

256Mbit, 512Mbit, and 1Gbit non-ECC memory technologies single-sided and double-sided DIMMS

DIMMs constructed with x8 and x16 DDR devices; DIMMs constructed with x4 SDRAM are not supported

✎

The system will not start if you install unsupported DIMMs.

Installing DIMMs

Ä CAUTION: The memory module sockets have gold metal contacts. When upgrading the memory, it is important to use memory modules with gold metal contacts to prevent corrosion and/or oxidation resulting from having incompatible metals in contact with each other.

Ä CAUTION: Static electricity can damage the electronic components of the computer or optional cards. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a

grounded metal object. For more information, refer to Chapter 4,

“Electrostatic Discharge.”

Ä CAUTION: When handling a memory module, be careful not to touch any of the contacts. Doing so may damage the module.

1. Turn off the computer properly through the operating system and turn off any external devices.

2. Disconnect the power cord from the power outlet and the computer, and disconnect any external devices.

3. Remove the computer access panel.

4. Locate the memory module sockets on the system board.

Å WARNING: To reduce risk of personal injury from hot surfaces, allow the internal system components to cool before touching.

5. Open both latches of the memory module socket 1, and insert the memory module into the socket 2.

Installing a DIMM

✎

A memory module can be installed in only one way. Match the notch on the module with the tab on the memory socket.

6. Push the module down into the socket, ensuring that the module is fully inserted and properly seated. Make sure the latches are in the closed position 3.

7. Replace the computer access panel and reconnect the power cable.

The computer should automatically recognize the additional memory the next time you turn on the computer.

Replacing or Upgrading a Drive

The computer supports up to five drives that may be installed in various configurations.

This section describes the procedure for replacing or upgrading the storage drives. A Torx T-15 screwdriver is needed to remove and install the guide screws and retainer screws on a drive.

Ä CAUTION: Make sure you back up your personal files on the hard drive to an external storage device, such as a CD, before removing the hard drive. Failure to do so will result in data loss. After replacing the primary hard drive, you will need to run the Restore Plus! CD to load the HP factory-installed files.
