You can follow this Dell Inspiron 5570 complete teardown guide for a full or partial laptop disassembly. There is a good chance these instructions will work for some other Dell Inspiron 5000 series laptops.
Steps 1-20 explain how to take apart the base assembly in order to access and remove all internal components.
Steps 21-28 explain how to remove and take apart the display assembly in order to remove the LCD screen and hinges.
Remove one screw securing the optical drive and pull the drive out.
The bottom cover secured to the palmrest assembly by 12 screws.
Three screws color-coded in yellow will stay attached to the bottom cover. You can unscrew them but do not try to remove completely. All other screws can be removed.
All screws have different length and I color-coded them differently.
Start separating the palmrest assembly from the bottom cover using a thin case opener tool. Pry up the palmrest to disengage hidden latches.
Continue separating the palmrest from the bottom cover with your fingers.
Now you can turn the laptop upside down and remove the bottom cover completely.
Removing internal Dell Inspiron 5570 components
With the bottom cover removed you can access all internal laptop components. Let’s remove them one by one.
Remove four screws securing the battery and unplug the battery cable.
Remove the battery (42Wh 11.4V type WDX0R).
If you are replacing it, I would recommend using a genuine Dell battery, not third-party replacements.

Remove four screws securing the 2.5″ hard drive bracket.
Disconnect the hard drive cable from the motherboard.

Remove one screw securing the optical drive connector board. Disconnect the board cable from the motherboard.
Here’s how to disconnect the cable.
Lift up the white locking tab (red arrow). Do not apply any force. The tab must stay attached to the connector.
Pull the cable out (yellow arrow).
Remove the optical drive connector board.
Remove one screw securing the wireless card cover. Remove the cover.
Pay attention how this cover installed so you know how to put it back in place correctly.
Disconnect both antenna cables from the wireless card. Carefully lift up the golden antenna connector to unsnap it from the card.
Remove the wireless card. Simply pull it out of the slot as you removed the SSD.
In Dell Inspiron 5570 the DC power jack mounted under the left hinge. In order to remove the DC jack it’s necessary to open the hinge.
Remove three screws securing the left display hinge.
Lift up the left hinge.
Now you can access the DC power jack.
Remove one screw securing DC jack to the case.
Disconnect DC jack cable from the motherboard and remove the harness completely.

Disconnect all shown cables from the motherboard.
Remove one screw securing the motherboard.
Here’s how to disconnect flat cables. Unlock the connectors first (red arrow) and after that pulled the cables out (yellow arrow).
Carefully lift up and remove the motherboard.
Here’s a picture of the other side, just in case you need it.

Removing and taking apart the display assembly
Unroute the display cable from the routing channel.
Remove two screws securing the right display hinge.
Lift up the right hinge (as you remember, we already lifted up the left hinge in the step 17).
Now you can separate the palmrest from the display assembly.
The USB SD card reader board still attached to the palmrest.
Notice that CMOS battery is connected to this board and can be easily removed if necessary. It’s a regular CR2032 3V lithium battery.
The trackpad also can be removed. The keyboard, on the other hand, permanently riveted to the palmrest and cannot be easily removed.

Now let’s take apart the display assembly and remove the LCD screen.
NOTE: the display can be disassembled while it’s still attached to the laptop base. It’s not necessary to remove the display completely in order to take it apart and remove the LCD screen.
Start separating the LCD bezel from the display cover. Wiggle the bezel in order to disengage hidden latches.
Continue removing the bezel.
Remove LCD bezel completely.
As I said, the bezel also can be removed without complete laptop disassembly.
In order to remove the LCD screen (not shown in my guide) you’ll have to remove four screws and disconnect the display cable on the other side.

Finally, you can remove both display hinges if you need to replace them.
The left hinge secured to the display cover by four screws.
The right hinge also secured by four screws.
Alternatively, you can use the official Dell Inspiron 15 5579 service manual which has full disassembly instructions.
