How to Fix the Left Button on a DS

Your Nintendo DS has two "shoulder" buttons located to the left and right of the screen. Many games require you to press the left button in order to perform a certain action in the game. Dirt and debris can get under the button, causing problems with the button's sensitivity. If you notice that your DS is not sensing when you press the left shoulder button, you can use several methods to clean out the debris and dust.

Things You'll Need

Cotton swab
Canned air

Instructions

- 1
  Use a dry cotton swab and gently wipe down the left shoulder button. You can press one side of the button down to reveal the inner part of the button; gently swipe the cotton swab around the inner components to remove dust particles.
- 2
  Use a can of compressed air to blow out any dust and debris from inside the left shoulder button. Hold the nozzle of the can a few inches away from the button so as not to damage the inner components with the blast of air.
- 3
  Place your lips close to the left shoulder button and blow into it. The air will force out debris and dust particles.
- 4
  Put a game cartridge into the DS and turn it on. Begin playing the game and test the left shoulder button to make sure it's working properly again.
