HP TouchSmart 9300 Elite All-in-One Business PC - Removal and Replacement Procedures

The following sections provide information about disassembling various components of the All-in-One.

Preparing to disassemble the computer

To avoid injury and equipment damage, always complete the following steps in order, when opening the All-in-One.

  1. Remove all removable media, such as compact discs or USB flash drives, from the computer.

  2. Turn off the computer properly through the operating system, then turn off any external devices.

  3. Disconnect the power cord from the power outlet and disconnect any external devices.

    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. You must disconnect the power cord to avoid damage to the internal components of the computer.
  4. Disconnect all cables from the ports.

  5. Place the computer face down on a soft flat surface. HP recommends that you set down a blanket, towel, or other soft cloth to protect the screen surface from scratches or other damage.

Static electricity can damage the electronic components of the computer. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object.
Beware of sharp edges inside the chassis.

Stand

The stand is secured with four screws. The screws are covered by the plastic piece covering the back of the stand.

To remove the stand:

  1. Prepare the computer for disassembly (see Preparing to disassemble the computer ).

  2. Insert your finger, or a flathead screwdriver, into the slot on the stand cover (1) to pry it off of the computer stand.

    1:

  3. Remove the four Torx screws (1), slide the stand toward the top of the computer, and then lift the stand off the computer (2).

    You can use a Torx or a flat-head driver to remove the screws.

    2:

To replace the stand, reverse the removal procedures.

Weight (with integrated graphics) without stand: 8.75 kg (19.3 lbs)

Weight (with discrete graphics) without stand: 9.05 kg (20.0 lbs)

VESA mount

The VESA adapter plate is stored in the bottom of the stand and is mounted in place of the stand.

To install the VESA adapter plate:

  1. Prepare the computer for disassembly (see Preparing to disassemble the computer ).

  2. Insert your finger, or a flathead screwdriver, into the slot on the stand cover (1) to pry it off of the computer stand.

    3:

  3. Use a Phillips screwdriver to tighten the recessed two brake screws (for the rails) on the computer. It should take about 5–10 turns of the screwdriver to secure the screws. Take care not to overtighten the screws.

    The tightened brake screws will hold the VESA adapter plate in the locked position, so that the computer does not slide down once it is mounted on a wall. These screws must be tighten before placing the VESA adapter plate on the back of the computer.

    4:

  4. While the stand is still on the computer, use a Phillips screwdriver to remove the four screws attaching the VESA adapter plate to the bottom of the computer stand. Save the screws.

    5:

  5. Remove the VESA adapter plate from the bottom of the computer stand.

    6:

  6. Use a flathead screwdriver to remove the four screws attaching the computer stand to the back of the computer.

    7:

  7. Lift the computer stand away from the computer.

    8:

  8. Place the VESA adapter plate over the rails on the back of the computer, matching the cutouts on the each side of the plate with the screw holes and the hooks on the rails.

    9:

  9. Attach the VESA adapter plate to the back of the computer, using a Phillips screwdriver to tighten the four screws.

    10:

  10. Slide the VESA adapter plate upward until it locks into place. You will hear a click when the VESA adapter plate is locked in place.

    If you do not hear the click or the plate does not lock in place, it means the two brake screws were not sufficiently tightened when the computer stand was removed. Unscrew the four screws on the VESA adapter plate and remove it, then retighten the two brake screws (see step 4 in previous section). Replace the VESA adapter plate by installing and tightening the four screws, then slide the plate up until it locks in place.

    11:

  11. Attach the wall-mounting hardware (purchased separately) to the VESA adapter plate, according to the manufacturer's instructions, using either the 100 mm x 100 mm screw holes or the 100 mm x 200 mm screw holes.

    12:

    13:

    The computer can be mounted in either landscape or portrait orientation. If mounted in portrait orientation make sure the CD/DVD drive is at the top. For landscape orientation, keep the same orientation as when the computer is on the stand.
If the computer stand is ever replaced on the computer, the VESA adapter plate must be replaced on the bottom of the computer stand in order to properly support the computer.

Note the following information about the computer without the stand but with the VESA adapter installed.

Installing memory

Description
Spare part number
4-GB
646801-001
2-GB
646800-001

The memory modules are located under the rear cover on the right side of the computer (when viewed from behind).

Memory location

20:

The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3-SDRAM) small outline dual inline memory modules (SODIMMs).

DDR3-SDRAM SODIMMs

For proper system operation, the SODIMMs must be:

  • industry-standard 204-pin

  • unbuffered non-ECC PC3-10600 DDR3-1333 MHz-compliant

  • 1.5 volt DDR3-SDRAM SODIMMs

The DDR3-SDRAM SODIMMs must also:

  • support CAS latency 9 DDR3 1333 MHz (9-9-9 timing)

  • contain the mandatory Joint Electronic Device Engineering Council (JEDEC) specification

In addition, the computer supports:

  • 512-Mbit, 1-Gbit, and 2-Gbit non-ECC memory technologies

  • single-sided and double-sided SODIMMs

  • SODIMMs constructed with x8 and x16 devices; SODIMMs constructed with x4 SDRAM are not supported

The system will not operate properly if you install unsupported SODIMMs.

Populating SODIMM sockets

The memory sockets on the system board can be populated with up to four industry-standard SODIMMs. These memory sockets are populated with at least one preinstalled SODIMM. To achieve the maximum memory support, you can populate the system board with up to 16 GB of memory.

There are four SODIMM 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.

SODIMM socket locations

A SODIMM must occupy the black DIMM1 socket. Otherwise, the system will display a POST error message indicating that a memory module is installed in the wrong socket

The system will automatically operate in single channel mode, dual channel mode, or flex mode, depending on how the SODIMMs are installed.

  • The system will operate in single channel mode if the SODIMM sockets are populated in one channel only.

  • The system will operate in a higher-performing dual channel mode if the total memory capacity of the SODIMMs in Channel A is equal to the total memory capacity of the SODIMMs in Channel B. The technology and device width can vary between the channels. For example, if Channel A is populated with two 1 GB SODIMMs and Channel B is populated with one 2 GB SODIMM, the system will operate in dual channel mode.

  • The system will operate in flex mode if the total memory capacity of the SODIMMs in Channel A is not equal to the total memory capacity of the SODIMMs 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. If one channel will have more memory than the other, the larger amount should be assigned to Channel A. For example, if you are populating the sockets with one 2 GB SODIMM, and three 1 GB SODIMMs, Channel A should be populated with the 2 GB SODIMM and one 1 GB SODIMM, and Channel B should be populated with the other two 1 GB SODIMMs. With this configuration, 4 GB will run as dual channel and 1 GB will run as single channel.

Installing SODIMMS

When facing the rear of the computer, there are four memory sockets located behind the large access panel on the right. You must remove this panel to remove or install memory.

Static electricity can damage the electronic components of the computer. Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a grounded metal object.

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

To remove or install memory modules:

  1. Prepare the computer for disassembly (see Preparing to disassemble the computer ).

  2. Remove the right rear panel (see Rear panels ).

  3. To remove a SODIMM, press outward on the two latches on each side of the SODIMM (1) then pull the SODIMM out of the socket (2).

    22:

  4. To install a SODIMM, slide the new SODIMM into the socket at approximately a 30° angle (1) then press the SODIMM down (2) so that the latches lock it in place.

    23:

    A memory module can be installed in only one way. Match the notch on the module with the tab on the memory socket.
  5. Reconnect and reconfigure the computer. The computer automatically recognizes the additional memory when you turn on the computer.
