How to disassemble Dell Inspiron 17R N7110

In this guide I will disassemble a Dell Inspiron 17R N7110 laptop.

My goal is to access and replace the hard drive which is mounted inside the laptop case. But I will disassemble it even

further. I will show how to remove the motherboard and other internal components.

This laptop has two different names: Dell Inspiron 17R and Dell Inspiron N7110.

Before you start make sure the laptop is turned off.

@ Ashok Kumar,

I don’t think you can install a WWAN card into Dell N7110.

I tried searching for “Dell N7110 WWAN card” and didn’t find any. Probably it’s not supported.

issue to fix.

Most likely it’s one of the following:

1. Poor connection between the video cable and motherboard or LCD screen. Try reseating the video cable

connectors on both ends.

2. If reseating connectors doesn’t help, probably this is defective video cable. Try replacing the cable.
