When the lights go out all over London

[edit] This issue solved thanks to usernamenumber's spare charger! Bertie Owen is (slowly, but I don't care) charging as we speak! Very serious thanks to everyone who offered or had a suggestion.

This question is addressed only to residents of Cambridge and Somerville—with the subways shut down and buses running only limited routes, I cannot be sure of meeting up with anyone else.

About a month ago, Bertie Owen's power cord died. That was not a disaster; my father had some months previous given me a backup power cord salvaged from a friend's ex-computer. It didn't appear to be as efficient as the original, but it charged the computer if you left it in long enough: whatever.

The backup power cord died tonight. I was working and didn't notice until the screen started dimming that my laptop's battery had run down to an hour. That is a disaster. Especially with the city shut down for snow and God knows the hours of the Apple Store and God knows the price of a new cord anyway. Especially with projects on my hard drive that I need access to. I cannot afford to be out of work right now.

Does anyone have a spare power cord suitable for a MacBook Pro 2009? It's the kind with the magnetic connector. I can write you poetry for it.

(I may rethink this entire proposition in the morning, but right now, God damn, did I not need this.)
