If you're worried about casual thieves then just about any kind of |
| 14 |
properly-implemented encryption will stop them. |

If you're worried about a government official specifically tasked with |
| 17 |
retrieving your computer, my understanding is that it is SOP these |
| 18 |
days to retrieve your computer without powering it off for just this |
| 19 |
reason. They won't use your UPS to do it. Typically they remove the |
| 20 |
plug just far enough to expose the prongs, slide in a connector that |
| 21 |
connects it to a UPS, and then they pull it out the rest of the way |
| 22 |
now powered by the UPS. |

Presumably somebody who is determined will also have the means to |
| 28 |
retrieve the contents of RAM once they seize your computer. Besides |
| 29 |
directlly accessing the memory bus I think most motherboards are not |
| 30 |
designed to be secure against attacks from PCI/firewire/etc. |
