So basically, if in doubt, 'try turning it off and on again'
Certainly sounds logical though. If the battery voltage has dipped low, without completely dying (a condition we call 'brownout' in electronics), digital circuits can end up in an unknown state due to the fact that some circuits will cease to function while others remain online, effectively causing some parts of the system to crash/hang.
Hopefully those steps will fix it. If not, since it's been stood a while, I'd suspect bad connectivity due to dampness. Has it been out in the rain? How dry is your electronics box?
