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.
Remove laptop battery.
There are four locks securing the keyboard on the top.
Each lock has a spring behind it.
Push the lock into the case with a small screwdriver.
At the same time lift up the keyboard a little bit. You can use a knife blade to lift up the keyboard.
While the keyboard is lifted, push in all other locks.
Finally, lift up the top side of the keyboard and place the keyboard upside down on the palmrest.
Now you can access the keyboard cable which is connected to the motherboard.
In the following two steps I explain how to unlock the connector and release the cable.
On this picture the keyboard connector shown in the locked position.
Lift up the left side of the brown tab with your fingernail. The tap will open up at a 90 degree angle.
