Today I will be taking apart a Dell Inspiron 17 5000 series laptop. This guide should work for Dell Inspirons 5759, 5758, 5755. All three models are very similar.
During the disassembly process I’ll go through the following major steps:
- Removing hard drive, RAM modules and CD/DVD drive – STEPS 1-5
- Removing keyboard and bottom case – STEPS 6-14
- Removing cooling fan, motherboard and DC power jack – STEPS 15-22
Release the battery lock and remove the battery.

Remove two screws securing the bottom cover. It might take some effort to separate the cover from the base. It has a few hidden latches.
Under this cover we get access to the hard drive, RAM slots, wireless card and CMOS battery.
Remove four screws securing the hard drive bracket.
Disconnect the hard drive cable from the motherboard.
In order to release the cable you’ll have to unlock the connector first (red arrow).
If you are replacing the hard drive or upgrading it to a solid state drive you will have to transfer the cable and the bracket.
Both memory slots are easily accessible and RAM modules can be removed and replaced if necessary.
Remove one screw securing the CD/DVD drive.
Pull the drive out.
In Dell Inspiron 17 5000 Series 5759/5758/5755 laptops the keyboard is secured by five hidden latches.
Insert a thin case opening tool between the keyboard and top case. Push the hidden latch inside the case.
At the same time lift up the keyboard to disengage it from the latch.
After you release all five latches you can lift up the keyboard and place it upside down on the palmrest.
Disconnect the keyboard and backlight cable from the motherboard.
As always, unlock the connector first and pull the cable out after that.
Now you can remove the keyboard and replace it if necessary.

Remove three more screws from the CD/DVD drive bay.
Start separating the bottom case from the top case.
While removing the bottom cover pay attention to the cables.
Continue separating the bottom case.
The bottom case might get stuck on the back. It happens because there are four latches securing it to the top case and they are located in the battery compartment.
Wiggle to bottom case to release the latches.
Remove the bottom case.
Here’s the other side where you can access both speakers and CD/DVD drive connector with cable.
Now we can access all internal components in Dell Inspiron 17 5000 Series 5759/5758/5755 laptop.
Remove three screws (red circles) and loosen there more screws (green circles) securing the heatsink assembly.

The display connector can be unlocked the same way as other connectors.
Lift up the locking tab (red arrow) and pull the cable out.
