Some of the pins are used as a logic supply voltage to determine battery charge level, temperature, etc. Most laptops won't provide a charging voltage to the battery terminals if there is no battery present. This is to prevent damage to the charging circuit by inrush current or shorts. When you say "won't boot", will the laptop turn on, post, and then hang, or will it not turn on at all?

That's a kinda generic bunch of issues there. Theres's a dozen things that could cause those. I won't argue the nvidia portion of your statement, but it's not just limited to Nvidia problems.
