In this guide I explain how to disassemble an HP ENVY 15 notebook. My goal is removing and replacing failed keyboard (a few keys stopped working).
In HP ENVY 15 notebook the keyboard is mounted to the top cover assembly. After the top cover assembly removed, you’ll be able to access the hard drive, internal memory modules, all three cooling fans and CMOS battery.
Before you start taking it apart, make sure the notebook is turned off and battery removed.
Remove three screws securing the memory cover.
Remove the cover.
Remove four rubber feet. They are glued to the laptop case with double sticky tape.
Remove all screws from the bottom of the notebook.
Now you can lift up and separate the top cover assembly from the notebook base.
Be careful. There are cables connecting the top cover assembly to the motherboard.
You’ll have to disconnect those cables before removing the top cover assembly.
1. LED board cable.
2. Touchpad cable.
3. Keyboard cable.
Unplug the LED board cable connector from the motherboard.
Pull the touchpad cable from the connector on the motherboard.
This connector has no locking mechanism.
In order to remove the keyboard cable you’ll have to unlock the connector first.
On the following picture the connector is shown in the locked position.
Very carefully lift up the brown locking tab about 2-3 millimeters.
The locking tab must stay attached to the connector base.
On the following picture the keyboard connector shown in the unlocked position.
Now you can pull the keyboard cable from the connector.
After all cables I mentioned in the step 6 are disconnected, you can remove the top cover assembly.
When the top cover removed, you can access:
- notebook hard drive.
- all internal memory modules/slots. HP ENVY 15 notebook has four memory slots.
- CMOS battery.
- all three cooling fans.
The keyboard is mounted to the top cover assembly and covered with black protective film.
Remove the black film.
Remove 60 (yes, sixty) tiny screws securing the keyboard to the top cover.
After all screws removed, you’ll be able to lift up and remove the keyboard.
Replace failed/damaged keyboard with a new one.
You can search for a new keyboard using the HP part number.

When I purchased a brand new keyboard (for use in the USA), it came with new screws and black Mylar shield (black protective film).
If your keyboard doesn’t have screws and Mylar shield, you’ll have to purchase it separately or reuse old screws and shield. Here’s HP part number for keyboard hardware kit (includes Mylar shield and screws): 576836-001
