Out of limbo

The burning question was whether the contents of Marcus's brain were wiped out completely, or whether the refrigerated conditions might have preserved something of the genius of the old man. With Rufus, it was possible to 'undelete' his dormant 'files' due to his hibernative state. Marcus wasn't in hibernation though, nothing was pumping through his veins anymore.

The machine realised that the brain is a series of electrical impulses. Perhaps the brain's electronics we're now in limbo, as the decay process had been delayed.

Maybe all it needed was a surge of power, to delimboise them! This required mains electricity!
