Today I’ll talk about the left hinge separation on Dell Inspiron 15 7000 series laptops, why it happens and how to fix this problem.
If your laptop hinge looks like one on the picture above, you are not alone. Apparently, the left hinge separation is a well known issue on Dell Inspiron 15 7000 series and many people complaining about it.
Here’s a typical hinge related complaint I found on the internet:
My Dell Inspiron 7559’s left hinge is causing the casing to separate. This problem has been present for about a month or two, which started as a clicking from the hinge when I’d open it, to now the top and bottom halves of the casing visibly separate near the hinge when the screen is upright.
How the hinge fails?
In order to answer this question we’ll have to remove the top cover and take a closer look inside at the problematic area.
The following picture was taken from a “healthy” Dell Inspiron 15 7000. The left hinge (same as the right one) is secured to the bottom cover by two screws.
Let’s remove the display and take a closer look at the screw nuts.
Both nuts that fasten the screws for the hinges are anchored in the plastic housings on the bottom cover.
Now let’s take a look at the damaged laptop.
The left hinge separated from the bottom cover because both nuts got pulled out of their respective housings.
Why the hinge fails?
In my opinion, the hinge screw anchorage wasn’t designed very well. It’s just too weak to support that massive laptop display. When you move the display up and down, you apply too much torque on the hinge and eventually both screw nuts get pulled out.
How to fix hinge separation?
If the housing is not damaged, you can try attaching the nut back in place using epoxy. Epoxy will properly fill the gaps between the nut and the housing and it’s strong enough to secure the nut in place.
On the other hand, if the housing is damaged and plastic walls are broken, you will have to replace the bottom case. I would advice to buy a new bottom case before you disassemble the laptop.

Is it possible for Dell fixing the hinge under warranty? Most likely not. Here’s what Dell Laptop Hinge Policy says about it:
Because a hinge is under the “normal wear and tear” policy, it is not covered by the default Limited Hardware warranty nor the Accidental Damage/Complete Care warranty. You will need to pay for the hinge repair using our “Support Service for Expired Warranties” offering.
