HP Compaq 8200 Elite All-in-One Business PC - Removal and Replacement Procedures All-in One (AIO) Chassis

The following sections provide information about disassembling various components of the computer.

Preparing to Disassemble the Computer

To avoid injury and equipment damage, always complete the following steps in order, when opening the HP Pro All-in-One.
  1. Remove all media (CD, DVD, etc.) from the computer.
  2. Shut down the computer.
  3. After the system has completely shut down, disconnect the power adapter from the back of the computer.
  4. Disconnect all other attached cables from the back of the computer.
  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.
  warning:
Beware of sharp edges inside the chassis.

Synchronizing the Optional Wireless Keyboard or Mouse

The optional wireless keyboard and mouse are easy to set up. Just remove the battery tabs on both the keyboard and the mouse. Also, make sure the Power switch on the bottom of the mouse is in the On position (the keyboard does not have a Power switch). Then, turn on the computer. If you have trouble using the keyboard and mouse, manually synchronize them as described below.
note:
For better mouse battery life and performance, avoid using your mouse on a dark or high-gloss surface, and turn mouse power off when not in use.
The wireless keyboard and mouse are pre-synchronized to work with your computer. The keyboard and mouse should work immediately after you first pull the battery tabs to activate the preinstalled batteries, and then turn on the mouse.
You may need to manually synchronize the wireless keyboard or mouse if they are not functioning. To synchronize them:
  1. Make sure the keyboard and mouse are next to the computer, within 30 cm (1 foot) and away from interference from other devices.
  2. Turn on the computer.
  3. Insert the wireless receiver into a USB port on the computer.
    Figure :
  4. Make sure the Power switch on the bottom of the mouse is in the On position (1).
  5. Press the Connect button on the bottom of the mouse (2) for five seconds. The blue activity LED from the wireless receiver illuminates when the synchronization command has been received and turns off when synchronization is complete.
  6. Press the Connect button on the bottom of the keyboard (3) for five seconds. The blue activity LED from the wireless receiver illuminates when the synchronization command has been received and turns off when synchronization is complete.
    Figure :
note:
If the procedure does not work, remove and then re-insert the wireless keyboard and mouse receiver from the back of the computer and then synchronize the keyboard and mouse again.

The computer comes with double data rate 3 synchronous dynamic random access memory (DDR3-SDRAM) small outline dual inline memory modules (SODIMMs).
The memory sockets on the system board can be populated with up to two 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 8 GB of memory.
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
note:
The system will not operate properly if you install unsupported SODIMMs.

  12. Raise and rotate the microprocessor retainer to its fully open position (2).
  13. Carefully lift the processor from the socket (3).
      caution:
    Do NOT handle the pins in the processor socket. These pins are very fragile and handling them could cause irreparable damage. Once pins are damaged it may be necessary to replace the system board.
    The heat sink must be installed within 24 hours of installing the processor to prevent damage to the processor’s solder connections.
    Figure :
To install a new processor:
  1. Place the processor in its socket and close the retainer. Make sure the slot in the processor fits into the post on the socket.
  2. Secure the locking lever. If reusing the existing heat sink, go to step 3. If using a new heat sink, go to step 6.
  3. If reusing the existing fan sink, clean the bottom of the fan sink with the alcohol pad provided in the spares kit.
      caution:
    Before reinstalling the fan sink you must clean the top of the processor and the bottom of the fan sink with an alcohol pad supplied in the spares kit. After the alcohol has evaporated, apply thermal grease to the top of the processor from the syringe supplied in the spares kit.
  4. Apply the thermal grease provided in the spares kit to the top of the processor and install the fan sink atop the processor.
  5. Go to step 7.
  6. If using a new fan sink, remove the protective covering from the bottom of the fan sink and place it in position atop the processor.
  7. Secure the fan sink to the system board and system board tray.
      caution:
    Fan sink retaining screws should be tightened in diagonally opposite pairs (as in an X) to evenly seat the fan sink on the processor. This is especially important as the pins on the socket are very fragile and any damage to them may require replacing the system board.
note:
After installing a new processor onto the system board, always update the system ROM to ensure that the latest version of the BIOS is being used on the computer. The latest system BIOS can be found on the Web at the HP Software and Drivers page.
