Before you begin
If the buttons on your Nintendo DSi aren't working properly, the input button pads may need to be cleaned or replaced. This guide will show you how to access, remove, and replace these input button pads. Because this device has been released for several years, the battery may be swollen. If the battery is swollen, make sure you handle it carefully and properly dispose of it. A swollen battery can explode or potentially cause a fire. Before you begin with this repair, please ensure the system is turned off and has no power source plugged in.
