ok, so i am not terribly sure what the cause of my problem is, so i am going to give the whole story with a painful amount of details. sorry. i got a macbook in the US in january. then i moved to the UK in february. i've been using the outlet adapter thing since i've been here. a couple of days ago, my husband bought a new macbook pro. UK, not US. i plugged my computer into his charger. oops. now my battery drains at the speed of light. i reset my battery, tried to do an update [but i got a window that said i didn't need one, so it wouldn't install] and reset my NVRAM/PRAM whatever. no dice. is my battery f'ed because i hooked it up to a charger for a pro, or because my computer is cool with the US voltage, and not the UK voltage? furthermore- if i buy a new battery here, can i just get a charger for UK outlets? i am very confused on all of this... everything i've read says that the voltage difference between the countries is no big deal and there should be no problem. so why does my battery drain completely in less than an hour now? someone help, please!
