Warnings and cautions Before performing upgrades be sure to carefully read all of the applicable instructions, cautions, and warnings in this guide.
Removing the computer access panel To access internal components, you must remove the access panel: 1. Remove/disengage any security devices that prohibit opening the computer. 2. Remove all removable media, such as compact discs or USB flash drives, from the computer. 3. Turn off the computer properly through the operating system, then turn off any external devices. 4. Disconnect the power cord from the power outlet and disconnect any external devices.
Replacing the computer access panel Slide the lip on the front end of the access panel under the lip on the front of the chassis (1) then press the back end of the access panel onto the unit so that it locks into place (2).
Removing the front bezel 1. Remove/disengage any security devices that prohibit opening the computer. 2. Remove all removable media, such as compact discs or USB flash drives, from the computer. 3. Turn off the computer properly through the operating system, then turn off any external devices. 4. Disconnect the power cord from the power outlet and disconnect any external devices.
Removing bezel blanks On some models, there are bezel blanks covering the 3.5-inch and slim optical drive bays that need to be removed before installing a drive. To remove a bezel blank: 1. Remove the access panel and front bezel. 2. To remove a slim optical drive bezel blank, press inward on the four retaining tabs (1) and pull the blank off the front bezel (2). To remove a 3.
Replacing the front bezel Insert the four hooks on the bottom edge of the bezel into the rectangular holes on the chassis (1) then rotate the top side of the bezel onto the chassis (2) and snap it into place.
Changing from desktop to tower configuration The Small Form Factor computer can be used in a tower orientation with an optional tower stand that can be purchased from HP. 1. Remove/disengage any security devices that prohibit opening the computer. 2. Remove all removable media, such as compact discs or USB flash drives, from the computer. 3. Turn off the computer properly through the operating system, then turn off any external devices. 4.
System board connections Refer to the following illustration and table to identify the system board connectors for your model. No.
Installing additional memory The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3SDRAM) dual inline memory modules (DIMMs). 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. To achieve the maximum memory support, you can populate the system board with up to 32-GB of memory configured in a high-performing dual channel mode.
● The system will operate in flex mode if the total memory capacity of the DIMMs in Channel A is not equal to the total memory capacity of the DIMMs in Channel B. In flex mode, the channel populated 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.
7. Open both latches of the memory module socket (1), and insert the memory module into the socket (2). NOTE: A memory module can be installed in only one way. Match the notch on the module with the tab on the memory socket. Populate the black DIMM sockets before the white DIMM sockets. For maximum performance, populate the sockets so that the memory capacity is spread as equally as possible between Channel A and Channel B. Refer to Populating DIMM sockets on page 14 for more information. 8.
Removing or installing an expansion card The computer has two PCI Express x1 expansion slots, one PCI Express x16 expansion slot, and one PCI Express x16 expansion slot that is downshifted to a x4 slot. NOTE: The PCI Express slots support only low profile cards. You can install a PCI Express x1, x4, x8, or x16 expansion card in the PCI Express x16 slot. For dual graphics card configurations, the first (primary) card must be installed in the PCI Express x16 slot that is NOT downshifted to a x4.
18 a. If you are installing an expansion card in a vacant socket, remove the appropriate expansion slot cover on the back of the chassis. Pull the slot cover straight up then away from the inside of the chassis. b. If you are removing a PCI Express x1 card, hold the card at each end, and carefully rock it back and forth until the connectors pull free from the socket. Pull the expansion card straight up from the socket (1) then away from the inside of the chassis to release it from the chassis frame (2).
c. If you are removing a PCI Express x16 card, pull the retention arm on the back of the expansion socket away from the card and carefully rock the card back and forth until the connectors pull free from the socket. Pull the expansion card straight up from the socket then away from the inside of the chassis to release it from the chassis frame. Be sure not to scrape the card against the other components. 10. Store the removed card in anti-static packaging. 11.
12. 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 (1) so that the bracket on the card is aligned with the open slot on the rear of the chassis. Press the card straight down into the expansion socket on the system board (2). NOTE: When installing an expansion card, press firmly on the card so that the whole connector seats properly in the expansion card slot. 13.

A Battery replacement The battery installed on the computer provides power to the real-time clock. When replacing the battery, use a battery equivalent to the battery originally installed on the computer. The computer has a 3-volt lithium coin cell battery installed. WARNING! The computer contains an internal lithium manganese dioxide battery. There is a risk of fire and burns if the battery is not handled properly. To reduce the risk of personal injury: Do not attempt to recharge the battery.
b. Slide the replacement battery into position, positive side up. The battery holder automatically secures the battery in the proper position. Type 2 a. To release the battery from its holder, squeeze the metal clamp that extends above one edge of the battery. When the battery pops up, lift it out (1). b. To insert the new battery, slide one edge of the replacement battery under the lip of the holder with the positive side up.
b. Insert the new battery and position the clip back into place. NOTE: After the battery has been replaced, use the following steps to complete this procedure. 8. Replace the computer access panel. 9. Plug in the computer and turn on power to the computer. 10. Reset the date and time, your passwords, and any special system setups using Computer Setup. 11. Lock any security devices that were disengaged when the computer access panel was removed.
B Electrostatic discharge A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device. Preventing electrostatic damage To prevent electrostatic damage, observe the following precautions: ● Avoid hand contact by transporting and storing products in static-safe containers. ● Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
C Computer operating guidelines, routine care and shipping preparation Computer operating guidelines and routine care Follow these guidelines to properly set up and care for the computer and monitor: ● 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.
Optical drive precautions Be sure to observe the following guidelines while operating or cleaning the optical drive. Operation ● Do not move the drive during operation. This may cause it to malfunction during reading. ● Avoid exposing the drive to sudden changes in temperature, as condensation may form inside the unit. If the temperature suddenly changes while the drive is on, wait at least one hour before you turn off the power. If you operate the unit immediately, it may malfunction while reading.
