Idle consumptions

This page reports the minimal consumptions of Thinkpads when idle. This means, in principle: minimum brightness, CPU and GPU at lowest speed, no wifi, hard drive spun down, no pcmcia cards inserted (see details of each entry).

This kind of information has several uses: comparing one's consumption with that of other people's setups, knowing which model to use as a gateway/file server, etc.
