No power – Nintendo DS
Charge your system
There are a number of reasons your Nintendo DS system will not turn on. Make sure your system is fully charged before starting.
The Power Button
The Power Button on Nintendo DS systems has been designed to be difficult to push, so that you don’t accidentally switch your system off while you’re playing. Make sure you’re pressing the button with enough force.
The AC Adapter
If you’re pressing the Power Button correctly, but your system will not turn on, it may be that your rechargeable battery is no longer working. Plug your AC Adapter in to both a power socket and your Nintendo DS, then try switching it on.
