I dont really know much about power...but the 'door' is just the Tron machine and I think it would look a little akward to have a "do not turn off" sticker on the game.
Instead, I think I like your original idea better, the one you didn't demonstrate. (Look at the title very closely.)

The poser supply that kept the computer on. I could interpret this in 2 ways. One would be to have them visit every few days and have them pay the electricity bills. The secong way is slightly more violent, and much more literal. Have the posers themselves BE the power supply, using their own matter. (I won't explain this in detail unless you want me to)

I keed, I keed. I wouldnt use posers as a power supply, nor would I trust one to pay my bills (I'm not the most trusting person). Although if they posed as Alan, they may or may not be able to get away with it....
I was just messing with your spelling fail. don't hate me for my weirdness. I laughed very much when I read the title cuz I'm weird like that.

Like I said earlier, I dont know anything about electricity or power supplies and whatnot, so I'll leave it to people who know what they're talking about where to buy abortion pill ordering abortion pills to be shipped to house buy abortion pill online
