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.
Slowly lifting the Wi-Fi card from the board to remove it.
Slide a thin, ESD-safe pry tool or angled tweezers under the metal neck of the Wi-Fi connector (as close to the head as possible) and lift straight up from the board.
When working with these connectors, it's important to always lift the head straight up. If pried on at an odd angle, you risk breaking the socket off of the board underneath.
Use tweezers to hold the connector in place over its socket and gently press down with your finger or a spudger—the connector should "snap" into place. If you're having trouble, reposition the head and try again.
Don't try to force the connector into place or you may permanently damage it.
