2Hardware upgrades
Serviceability features
The computer includes features that make it easy to upgrade and service. A Torx T15 or flat-bladed screwdriver is needed for some 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.
WARNING! To reduce the risk of personal injury from electrical shock, hot surfaces, or fire:
Disconnect the power cord from the AC outlet and allow the internal system components to cool before you touch them.
Do not plug telecommunications or telephone connectors into the network interface controller (NIC) receptacles.
Do not disable the power cord grounding plug. The grounding plug is an important safety feature. Plug the power cord into a grounded (earthed) outlet that is easily accessible at all times.
To reduce the risk of serious injury, read the Safety & Comfort Guide. It describes proper workstation setup, and proper posture, health, and work habits for computer users. The Safety & Comfort Guide also provides important electrical and mechanical safety information. The Safety & Comfort Guide is available on the Web at http://www.hp.com/ergo.
WARNING! Energized and moving parts inside.
Disconnect power to the equipment before removing the enclosure. Replace and secure the enclosure before re-energizing the equipment.
IMPORTANT: 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 Electrostatic discharge on page 45 for more information.
When the computer is plugged into an AC power source, voltage is always applied to the system board. To prevent damage to internal components, you must disconnect the power cord from the power source before opening the computer.
Serviceability features |

Preparing for disassembly
1.Remove/disengage any security devices that prohibit opening the computer.
2.Remove all removable media, such as compact discs and USB flash drives, from the computer.
3.Turn off the computer properly through the operating system, and turn off any external devices.
4.Disconnect the power cord from the AC outlet and disconnect any external devices.
IMPORTANT: Regardless of the power-on state, voltage is always present on the system board as long as the system is plugged into an active AC outlet. To prevent damage to internal components, you must disconnect the AC power cord from the power source before opening the computer.
Removing the computer access panel
To access internal components, you must remove the access panel.
1.Prepare for disassembly. See Preparing for disassembly on page 6.
2.If the computer is on a stand, remove the computer from the stand and lay the computer down.
3.Slide the access panel release lever to the right so that it locks into place (1). Then slide the access panel toward the rear of the computer (2) and lift it off the computer (3).
6Chapter 2 Hardware upgrades
Replacing the computer access panel
Be sure that the access panel release lever is locked into place, and then place the access panel on the computer (1) and slide the panel toward the front of the computer (2). The release lever will automatically move back to the left and secure the access panel.
