Hewlett Packard's XW4200 is an older workstation computer geared toward large office environments needing a mid-range computer that can handle a variety of work tasks. The HP workstation can be configured with a variety of system components, including a range of Intel Pentium 4 processors. The components of the XW4200 are user-upgradeable, although opening your workstation case may void the warranty.

Instructions

  1. 1

    Restart your XW4200 workstation and hit F10 to enter BIOS. Allow the computer to idle in BIOS for five minutes. The idle temperature in BIOS is higher than the idle temperature in Windows, and HP recommends using this process to loosen the bond between the thermal compound and the processor.

  2. 2

    Shut down the XW4200 workstation. Remove all cables connected to the back.

  3. 3

    Lay the workstation down on its side. Flip the latch on the side up and slide the panel down. Pull the panel off of the workstation.

  4. 4

    Remove the fan's power cable from the motherboard. Unscrew the heat sink screws by loosening two diagonal screws then the other set of screws. Remove the screws completely after loosening them.

  5. 5

    Move the heat sink in a twist to break the seal between the thermal compound and the processor. Remove the heat sink from the computer. You may need to use rubbing alcohol to clean excess thermal compound off of the processor or heat sink. Wait for the alcohol to dry before continuing.

  6. 6

    Press the lever next to the CPU socket up. Flip the protective CPU cover open. Remove the current processor from the computer with your fingers. Put the new CPU into the socket. Close the protective cover and push the lever into place. Spread a dab of thermal compound on top of the cover.

  7. 7

    Tighten the heat sink screws a small amount at a time, moving to the opposite diagonal screw in turn. Once all screws are slightly tightened, secure each one completely. Plug the CPU fan into the motherboard. Slide the access panel into place and put your workstation upright. Plug the cables in.
