HP ENVY 17t-K200 disassembly guide

In this HP ENVY 17t-K200 disassembly guide I explain how to open up the laptop body and access all internal components. There is a good chance this guide will fit some other models in the HP ENVY 17 Notebook PC line.

I’m taking it apart in order to access the CMOS battery which is mounted on the bottom side of the motherboard.

This HP laptop stopped booting without any reason. It was turning on but the Caps lock LED blinked twice every 3 seconds and nothing appeared on the screen. I found that removing the CMOS battery might resolve the problem and it did help.

STEP 1.
Start the disassembly process with removing the battery.
Unlock the battery first by pushing the left tab to the left (red arrow).
Lift up the battery by pushing the right tab to the left (green arrow).

STEP 2.
Remove two screws securing each hinge cover.

Remove two screws located under the right hinge cover. The silver screw (color-coded in yellow) is shorter than the other screw (red). Make sure to install them back correctly when putting the laptop back together.

STEP 8.
Now you can start separating the palmrest assembly from the base. I’m using a plastic case opening tool for that. Move the tool along the side and pry the palmrest up to unlock hidden latches.

STEP 9.
Continue separating the palmrest assembly with your fingers. There are many hidden latches. Wiggle the palmrest until it separates from the base.

STEP 10.
I found that moving the palmrest assembly away from the display helps to release latches on the back.

STEP 11.
Before you remove the palmrest completely, you’ll have to disconnect for flat cables from the motherboard. These are: power button cable, finger scanner cable, keyboard cable and trackpad cable.

Now we are going to separate the display assembly from the base. We’ll have to remove screws from the display hinges and disconnect display cable (color-coded in green) and wireless antenna cables (color-coded in yellow).

There are four screws securing the left hinge to the base. One of them (silver) is shorter than three other screws.
There are three screws securing the right hinge to the base.

Fixing caps lock blinking twice and blank screen

As I mentioned earlier, this HP ENVY 17t-K200 laptop stopped booting properly showing a blank screen and caps lock blinking twice. In order to fix this problem I had to remove the CMOS battery and turn on the logic board from the AC adapter. Thank you to HP forums for the solution.

After re-assembly, the laptop turned on properly with video on the screen.

    I found some keyboard sold on eBay but you said it cannot be replaced. Would you clarify please? Thank you.

      Lorenze, technically it is possible to replace just the keyboard but it’s not easy. Take a look at the step 12. As you see the keyboard is mounted under the metal plate which is riveted to the top case. In order to replace the keyboard it’s necessary to break all the rivets securing that metal plate. After that you should be able to replace the keyboard but you’ll have to find a way to reattach the metal plate back in place.
