Can I connect a battery to the MacBook while it's running?
TL;DR, I got a dodgy battery that doesn’t like to charge, so the battery is disconnected right now and I’m using the laptop in AC-only. What happens if I try to plug the battery in while the Mac is powered-on and running?

Don't do it!
I tried it without thinking - old battery was disconnected, laptop was in AC-only, then I plugged the battery. Instant turn-off and laptop doesn't respond anymore. Charging shows orange.
I wonder what's broken now. I'm waiting for a cheap $5 DC-in board to arrive but if that doesn't fix it my guess will be that the logic board is dead :(
