Introduction

A broken screen severely hinders the usefulness of a laptop. The symptoms of display damage range from a few nonfunctional pixels to visible cracks or even deformation in the display. This series of HP laptops features a display panel located behind a plastic or glass sheet. If the display damage is localized to the display panel, then replacing this part should restore the screen to working order.

As with all guides that involve disassembling a computer, it is recommended to first backup all important data stored on the laptop if possible. Additionally, since the sensitive internal electronics will be exposed during the repair, be sure to take the necessary Electrostatic Discharge precautions.

Although this guide should be applicable to the entire 17t-k000 family of HP laptops, note that your laptop may differ from the exact model pictured in the steps.

What you need

Step 1

Step 6

  • Remove the following screws from the back case and corner covers:
  • Eighteen 6 mm Phillips #0 screws
  • Two 7 mm Phillips #0 screws
  • If you do not have a magnet that can lift the screws out, you may have to turn the laptop over until each screw drops into your hand.
  • Do not proceed unless all the screws are out! You can severely damage your keyboard in the following steps if you still have a screw in place.

Step 10

  • Begin prying up the keyboard at a front corner of the laptop with a plastic opening tool.
  • Continue prying up the keyboard, working your way toward the other front corner and then along the sides.
  • Don’t lift the keyboard out yet when it separates from the frame. It still has cables attached on its underside!
  • It is normal to hear loud pops and clicks at this step.

Step 11

  • Disconnect the four ribbon cables that come from the underside of the keyboard.
  • To release each ribbon cable, gently pry up the retention clamp with a fingernail or plastic spudger to a 90 degree angle. Then, pull the cable out.
  • Double-check that all cables connecting the keyboard to the base of the laptop have been completely disconnected before removing the keyboard.
  • Lift the keyboard up and set it to the side.

Step 19

  • Follow the display cable back toward the hinge cover, carefully pulling it up from the routing channel as you go.
  • Don’t pull hard on the cable. If you have trouble getting it to come out of the channel, try pulling or even pushing from a different angle.
