(Yeah, there's another thread of mine on the first page, so what?)
So I have one of the original GBA SP's from 2002. I found it about 6 months ago when cleaning, and started it up. It had juice so I started to play it. I noticed something(s) wrong. For some reason, I have to flick the switch on and off a few times to turn it on. The light instantly turns to red, even though it didn't seem to have a low battery. Everything was fine until today, I tried to charge it and the orange light stays on for about 2 seconds and then goes off. I tried again and again, and to no avail, it still didn't work. I'm really stumped about this because I couldn't find anything similar online. I also forgot to mention that I have been playing it periodically since I found it. I think I last used it in 2008 or 2009. Please help me.
