u/yably

I have had my Alphasmart Neo for about three months now without any issues. Last week I got the bus error prompt, which I thought to solve by replacing the coin battery. Now, I keep having the same issue, while it also only turns on to show me the error one out of every five times I press on/off. If I manage to do a factory reset, it works fine for a while, even turning off and on smoothly. Then, after a while, I'm back to getting the error and the trouble with turning on.

Any tips at all? Im afraid it might be the end...
