So I have a old dsi that I want to give to a friends little sister. When I first opened it up to change a few of the features I realized something was wrong with the fact that it wouldn’t turn on for its usual few seconds even without a charge. I dismissed it and put it on the charger. After about an hour of charging and an impatient 9 year old I took it off the charger and tried turning it on, when it didn’t power on I went online for answers and followed one solution, I unscrewed the battery covering and popped the battery out for five minutes then put it back in and put it back on the charger. After a while I took it off the charger again and tried turning it on and it still doesn’t turn on.
