In this guide I explain how to remove and replace the LCD screen on a Dell G3 15 3579 (model P75F) laptop.

It’s easier to remove and replace the screen if the display already removed but also possible if the display is still attached to the laptop base (as shown in my example).

By the way, for complete laptop disassembly check out my previous Dell G3 15 3575 guide. Before removing the LCD screen I recommend disconnecting the main battery.

STEP 1.
Insert your fingers between the display bezel and the LCD screen. Wiggle the bezel and start separating it from the back cover. While pulling the bezel away from the screen, pry up the bezel with a case opener tool. You’ll have to disengage hidden latches that secure the bezel to the back cover.
