How to Remove the LCD Panel Display Assembly From an HP Laptop
Removing the screen assembly from an HP laptop is a task that can vary quite a bit from model to model. Most newer models of HP laptops use similar architecture, which makes it possible to provide a general outline of the removal procedure. Specifics about your model can be located in the laptop's manual or on the HP Support website. Removing the screen assembly could allow you to replace it with another screen in instances of screen failure. Prior laptop screen repair experience or knowledge is recommended.

Unplug the wireless card antenna. Most models have a cover on the bottom of the computer that can be unscrewed to reveal the wireless card wires. If the wireless card area is not marked with the wire placements, take note of which wire goes where. Unplug the wires (usually black and white) from the co-axial ports on the card. The card does not need to be removed. If the wires are clipped in to the laptop base, free them so that you can pull up on these wires later when removing the screen.

Remove the power button board/bezel to gain access to the screws securing the screen assembly. The power button board/bezel is usually attached by a few screws on the bottom of the laptop, located directly under the bezel. Remove the screws, then gently pull up on one of the corners of the power button board/bezel. In some cases, a small flat-head screwdriver will assist in this task. Gently remove the power button board/bezel and disconnect any cables or wires.

Unplug the screen's video cable from the motherboard or graphics card. Remove the hinge screws that are now revealed. Some models also have screws securing the screen assembly on the back of the laptop base. Gently pull up on the screen once you have removed all of the screws. The wireless antenna wires should come sliding through the middle of the motherboard, but might get caught on something along the way. If the wires do not come out, you may have to remove the keyboard to free them. If so, flip the laptop over and unscrew any screws marked by tiny keyboard pictograms. If they aren't marked, you may have to test one by one until the keyboard comes free. Unplug the keyboard and remove it. You should now have access to the wireless antenna wires, and be able to completely free the screen assembly.
