Remove display from Dell Inspiron 15 7559 7557

Replacing failed video cable on a Dell Inspiron 15 7000 series 7559 7557 is a relatively complicated and time consuming process. In my case the laptop had a touch screen and because of that the disassembly process was even more difficult.

Why do I replace the video cable? This laptop has developed a very annoying problem. As soon as you open the display more than 90 degrees, the backlight turns off. You move the display back and the backlight turns on.

  1. Is it possible to replace just the keyboard without replacing the entire top case? It’s possible but not easy. The keyboard is riveted to the top case. Take a look at the last picture.
  2. Is it possible to upgrade RAM? No, it’s not. The RAM is integrated into the motherboard. It’s shown in the step 11.
