The processor installed in your Compaq Presario C500 laptop is the main component that determines the computer's speed. When new software installs slowly or programs don't respond as quickly as you need, a processor upgrade can improve performance. For a faster computing experience, you may want to replace the Celeron processor installed in your C500 laptop with a faster Pentium M unit. The processor is connected directly to the laptop's motherboard and is hidden underneath several other components.
Instructions
1. Turn off the C500 laptop and disconnect any devices or cables plugged into the computer's ports. Shut the laptop's lid and turn the device over so the battery is visible at the bottom of the case.
2. Push the battery lock slide bar over to the "unlock" position and lift the rectangular battery pack out of the C500. Locate the two Phillips screws on the hinges at the back of the laptop. Remove both screws and turn the laptop over.
3. Open the LCD screen and push it back until the laptop is lying flat. Push your flat-head screwdriver underneath the right hand edge of the plastic strip positioned above the keyboard. Pry the plastic strip off the case and set it aside.
4. Use a Phillips screwdriver to remove the four screws above the keyboard. Lift the keyboard up and unplug its cable. Pull the keyboard off the laptop.
5. Remove the single screw above the mouse touch pad and the three screws at the top of the palm rest. Pull the palm rest off the laptop to reveal the fan and metal heat sink at the left side of the laptop's motherboard.
6. Disconnect the fan's cable from the motherboard and remove the three screws locking the heat sink. Pull the fan and heat sink out of the laptop to find the Celeron processor in the square motherboard socket.
7. Use a flat-head screwdriver to turn the Celeron's locking screw counterclockwise one turn. Pull the Celeron processor straight out and set it aside.
8. Set the Pentium M processor over the square motherboard socket and push down gently. Turn the locking screw clockwise one turn with a flat-head screwdriver. Spread a layer of thermal paste on top of the Pentium M to keep the processor cool while it runs.
9. Replace the fan and heat sink and tighten the screws you removed. Plug in the fan's cable and reassemble the keyboard and plastic strip. Replace the battery pack and turn on the laptop.
