mmm... Nothing! This is a tricky one.
 
Lets assume you didn't damage anything then I would guess the PRAM battery needs to be replaced. Its likely the main battery had enough charge to hold the settings alassettings. Alas, once you took the main battery out the PRAM lost its settings and can't reset as it doesn't have power (Egg before Chicken problem). Here's the IFIXIT guide: [guide|462|MacBook Pro 15" Core 2 Duo Model A1211 PRAM Battery Replacement]. I would start there as long as the charger & battery are good.

Unlike the newer systems the PRAM battery holds the settings when you pull the battery or have a dead battery. I suspect you ran it down as you stated it was sitting idle for a while and over time they do wear out.
