The Cooling System: You’ll now see the fan and the copper heatsink. To clean it or replace the thermal paste, unscrew the fan and the numbered screws on the heatsink over the CPU.

Motherboard Removal: Finally, after disconnecting the display cable and a few last screws, the motherboard can be lifted out entirely.

4. Remove RAM modules

2. Remove the service cover

Step 5: Remove Keyboard

The keyboard is secured from the top, but screws from the bottom hold it.

  1. Turn bottom-side up. Locate the 3 screws marked with a keyboard icon (usually near the top edge under the service cover area). Remove them.
  2. Turn laptop right-side up, open lid.

Pre-Disassembly Safety & Preparation

  1. Power down completely – Shut down the OS, then hold the power button for 10 seconds to drain residual charge.
  2. Unplug all peripherals – USB drives, Ethernet, external monitors.
  3. Work on a clean, static-free surface – Avoid carpets and wool clothing.
  4. Photograph each step with your phone – this will help during reassembly.

Step 5 – Remove the Top Cover (Palmrest Assembly)

This is the most tedious part of the HP ProBook 450 G0 disassembly due to hidden screws and plastic clips.

  1. Remove all screws from the bottom chassis:

    • After the service door removal, you’ll see several screws marked with a keyboard icon (these fasten the top cover).
    • Also remove screws near the optical drive bay and RAM slot area.
    • Check the battery compartment – there are often 2–3 hidden screws under sticker labels.

  2. Disconnect the touchpad ribbon cable and fingerprint reader cable (if present) from the motherboard. You may need to remove the WLAN card temporarily to access these connectors.

  3. Flip the laptop right-side up. Use a plastic spudger to separate the palmrest from the bottom case. Start at the left or right edge near the optical drive bay.

  4. Work slowly around the perimeter, popping clips loose. Do not use a metal tool – it will mar the plastic.

  5. Once all clips are free, lift the top cover gently, minding any remaining cables (touchpad, power button board). Disconnect those cables.

  6. Set the top cover aside.

6. Remove optical drive (if present)
