How to disassemble Lenovo ideapad 110-15ISK model 80UD

In this guide I show how to disassemble Lenovo ideapad 110-15ISK (model 80UD) manufactured in the year 2017.

In the first part of the guide I will show how disassemble the laptop base and in the second part I will take apart the display panel and remove the LCD screen.

Both parts are independent form each other and if you need to replace the screen, you can jump to the second part.

By the way, if your Lenovo ideapad 110 series laptop looks different than one shown in this guide, take a look at my previous guide for model 80T7 manufactured in 2016.

Lenovo ideapad 110-15ISK base disassembly.

STEP 1.

Remove two screws from the bottom. These two screws securing the keyboard.

Pry the keyboard up.

STEP 4.

Keep moving the opener tool along top side of the keyboard and continue separating it from the top case.

STEP 5.

Upgrading this regular hard drive to a 2.5″ SATA solid state drive will improve laptop performance significantly.

Start separating the screen bezel from the display back cover on the top. Insert your fingers between the bezel and the screen.

Wiggle the bezel to unfasten it from the back cover.

STEP 2.

It’s easier to remove the bezel with a plastic case opening tool.

Continue separating the bezel on both sides of the display.
