Repairing Nintendo DS Lite Volume Switch

Unscrew the Phillips screw securing the battery cover to the lower case.

Pry the battery cover upward with a spudger or fingernail, and lift out of the lower case.

Wedge the edge of a spudger in between the side of the battery and the lower case housing and pry upward to dislodge the battery.

Remove the battery from the DS Lite.

Use the tip of a spudger to pry both rubber feet off the DS Lite.

Remove the following screws securing the lower case to the body of the DS Lite:

Two 4.3 mm gold Phillips screws

One 3.9 mm black Tri-point screw

One 3.3 mm silver Phillips screw

Three 5.5 mm silver Tri-point screws

Insert the edge of a spudger in between the lower and upper case near the top right corner of the DS Lite.

Carefully run the spudger along the right edge of the DS Lite, creating an opening in the process.

Continue running the spudger along the backside of the DS Lite until the majority of the lower case has been separated from the upper case.

Lift the lower case away from the rest of the DS Lite.

Carefully use a pair of tweezers to remove the volume switch.
