A nintedo ds

Your machine is very likely to have been wrecked. Sorry, but if you get your mind round that now, any success at all you have recovering it will come as a bonus rather than a disappointment. At least it didn't get dropped into seawater. Your absolute first priority is to take the battery out. Look for a big door on the bottom held in place with a single crosshead screw. Open that, remover the battery, blot it dry with a tissue and then leave the door open (with all the bits kept together so you don't lose any of them). Have a look at the battery terminals (both on the battery and in the DS). The state of the positive terminals is usually quite a good indicator of the amount of damage that's happened inside. If the plating on one set of terminals is badly corroded, then the overall outlook is bleak. If the terminals are still clean, then there's a better chance it will work to some extent, though what state the displays will be in remains to be seen. My next move would probably be to rinse the DS out with three or four changes of distilled water - even if all that was in the toilet when the DS was dropped in was fresh water. After that comes the drying process. If it was me, I'd take the DS to bits, but unless you have an established track record putting things like this back together again, I'd recommend that you don't disassemble any further. Blot what you can get to dry with a tissue, then leave the DS to stand on edge in a warm (but not hot), dry, draughty place for a couple of weeks. The secret is to let it dry out naturally rather than to try to force it, and dry for longer than you expect to be necessary. Be very patient. Once you are confident all the moisture is gone, you can put the battery back in, recharge it, and see whether anything works. Best of luck. Post any follow-on questions as comments to this one, and I'll keep an eye on it for a while. A.
