HP Pavilion DV6-3000 Laptop Repairs - Bottom Case Replacement

This HP Pavilion DV6 laptop has been over-heating and recently has broken its bottom casing at the left hand side. Due to the damage, the laptop lid can no longer close.

How To Repair Your Laptop

Since the bottom casing is broken, we will need to replace it. This bottom casing is underneath the laptop’s motherboard, fan, heatsink, screen and everything else so this job won’t be as easy as it sounds like. Get ready to disassemble the whole laptop to replace the bottom cover.

Let’s first remove the laptop keyboard.

Disconnect all ribbon cables that you see here then remove the laptop keyboard cover.

The laptop display panel is attached onto the bottom casing, we will need to take the display unit apart from the bottom casing too.

Now we would have the laptop motherboard in its bottom casing left. Let’s remove the motherboard.

Now the motherboard is removed, take a look at the fan and heatsink units and you’ll see why the bottom casing went broken. We’ll need to remove the fan and heatsink from the board itself, then detach the fan from its heatsink.

The heatsink is completely covered in dust, there is no gap for the heat to go out, this caused over-heating problems with this HP DV6 laptop.

Using a computer brush, air duster and cleaning oil to clean out the heatsink and the laptop fan. This will stop the laptop from over-heating.

To make it even better, we will use electrical tape to wrap around the gap between the heatsink and the fan to stop dust getting into the heatsink.

Now the cleaning is done, we’ll move on to replacing the bottom casing. Let’s take a look at the damaged bottom case.

The left side of the bottom cover is damaged, thus it couldn’t give support to the display panel, which led to the facts that the laptop could not close.

Now make sure to remove the remaining parts from the bottom case too, this includes USB ports, ribbon cables, DC power jack, etc. We will need to fit all of these small parts onto the new bottom cover.

Once that’s done, we are now ready to take out a new bottom cover and reassemble the laptop in reversed order of this guide.

This process should be easier than taking the laptop apart since you’re already familiar with the build of this laptop.

With the new bottom casing, the laptop will now be able to close normally.

Over-heating problem is also fixed for good after we have cleaned out the dust.
