it doesnt need battery because the metal is connected to it.
it doesnt
No, it has so many features that the battery doesnt really last through the whole day.
when it doesnt come on when you put it in the phone or when its in 2 parts.........
probably have a bad alternator or voltage regulator or bad battery cables
It depends why it doesn't work. If it is just flat, then usually you can. If the battery has been damaged then maybe not.
Your battery is probably "broken" Check if you have disabled battery charging And if the charging light is on it is charging and its a good thing. Also check the adaptor with a multimeter (UNPLUG IT FIRST)
youll need to first wire up the socket to battery.
This is often from a dead battery.
if replacing the battery doesnt fix it.
no it does not, some downloads you can download for free might. but the 3ds itself doesnt (ok the battery power sucks a bit, doesnt last that long)
Anytime a battery cable is removed from the battery the radio will need to have the clock reset and the radio stations re-programmed. (Helpfull)
you should go to the doctors if the swell doesnt go away.
