In this guide I show how to disassemble a Dell Inspiron 1764 laptop and access internal laptop components.

I’m taking it apart because it started overheating and the cooling fan started making rattling noise.

As always, make sure the computer is turned off before you start taking it apart.

    Overall this is a great site. I noticed one problem on On removing the top cover, you forgot to mention 2 screws that needed to be removed from the bottom. They are located at the top right/left corners. They are essential for the removal of the top cover.

    Just wanted to let you know…

    Keep up the good work!

    Eeww! Same problem here. Lots of cat hair and dust.

    Thanks for the step-by-step. I was on my way to figuring it out myself, then I got stuck. :^)

    After doing the cleaning, I decided to add new paste. I also noticed new thermal pads were in order. I unfortunately didn’t take a look at the type of pad I would need. Do you happen to know if I can use any or do specific ones need to be used? Thanks.

    Great job, hoping this will help my 1764, it’s running hot and high cup after 3 – 4 hours.

    Thanks mate. My wife’s laptop was crashing with no explanation and the fan was running constantly, it was also running very slow. Followed you guide and now it runs like new.
