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.
