Remove the hard drive assembly from the notebook.
If you are going to replace it with another hard drive or SSD, you will have to transfer the mounting bracket and the SATA cable.

When the keyboard fails, it’s necessary to replace the top case.
The touchpad is glued to the top case but the touchpad button board can be removed.
HP 15 notebook PC LCD screen removal.
This part of the disassembly guide is independent from the first part. You can disassemble the display without going through all previous steps but don’t forget to disconnect the battery before you start.
Start separating the display bezel from the back cover. You’ll have to wiggle the bezel to unfasten it from the cover. Start on the top and move to the sides fo the display assembly.
On the bottom the bezel is attached to the LCD screen with adhesive tape. Carefully separate it from the screen.
Remove the bezel completely.
Remove four screws securing the LCD screen to the side brackets.
Separate the LCD screen from the back cover and place it the front side down on the keyboard.
Now you can access the video cable connector.
Peel off the grounding tape from the screen.
Peel off the clear tape securing the connection and unplug the video cable from the screen.
Remove the LCD screen completely and replace if necessary.
You can find a new LCD screen using the model number from the original one. In my case the model number is: B156XTK01.
