Dell Inspiron 5570 complete teardown

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.

STEP 1.
Remove one screw securing the optical drive and pull the drive out.

STEP 2.
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.
