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.
STEP 1.
Remove three screws securing the memory cover.
STEP 2.
Remove the cover.
STEP 3.
Remove four rubber feet. They are glued to the laptop case with double sticky tape.
STEP 4.
Remove all screws from the bottom of the notebook.
STEP 5.
Now you can lift up and separate the top cover assembly from the notebook base.
STEP 6.
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.
STEP 7.
Unplug the LED board cable connector from the motherboard.
STEP 8.
Pull the touchpad cable from the connector on the motherboard.
This connector has no locking mechanism.
STEP 9.
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.
STEP 10.
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.
STEP 11.
Now you can pull the keyboard cable from the connector.
STEP 12.
After all cables I mentioned in the step 6 are disconnected, you can remove the top cover assembly.
STEP 13.
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.
STEP 14.
The keyboard is mounted to the top cover assembly and covered with black protective film.
STEP 15.
Remove the black film.
STEP 16.
Remove 60 (yes, sixty) tiny screws securing the keyboard to the top cover.
STEP 17.
After all screws removed, you’ll be able to lift up and remove the keyboard.
STEP 18.
Replace failed/damaged keyboard with a new one.
You can search for a new keyboard using the HP part number.
HP ENVY 15 notebook have keyboards with bronze finish and black finish.
Here are keyboard part numbers I found in the official service manual:

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

Thanks for the quick reply. This helps – I had opened up my laptop and was stuck at removing those screws!
Will it be ok if I reuse the original mylar sheet? I ordered the replacement keyboard from ebay since I am in India now and they sent me just the keyboard – no mylar sheet or screws.

@ Mathew,
I was using Wiha PH00 Phillips screwdriver.

What kind of screwdriver I need to remove the 60 screws that are on the keyboard?
December 15th, 2012 at 9:37 am
@ Berik,
I don’t think you can buy a cable separately. Most likely the touchpad is part of the top cover assembly (palmrest assembly).
You can search on eBay for a replacement top cover.

@ Nebb,
Perhaps it’s not very difficult to figure out.

Perhaps it’d be ideal to tell people that they are going to need VERY small screwdrivers to actually get out the screws.

Maybe the last HP laptop we see for a while if the news is anything to go by. They’ve been nothing but trouble though with the video chip fault they all seem to develop.

Hello again! I finally make it works! Although the solution is a little bit “twisted”, and not all the people will have the necessary parts/components to make it work. But at least is a valid solution!
After a lot of problems and testing i finally did it.
I used an hp pavillion dv6 2150es HDD (it has the same Hitachi hdd than the envy 15) and i cloned it in my new samsung hdd.
Of course i had to install some drivers (usb 3.0 and others), and i lost the recovery options from the initial boot of the computer but anyway the system is working perfectly again, and that´s what i wanted. No blue screens, no problem at all until now, hope keep this way.
I think if you can use any hdd with system installed with an intel cpu of the same family and similar chipset you can make it work! You have to have this, i know not all the people have this possibility, but at least is an option to have your laptop working again.
Thanks for you help and hope this solution is usefull for someone!
