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.


Model OS Remarks consumption
600E PII/366 Debian Lenny/2.6.21 gnome back light off, laptop-mode-tools enabled, fan on, idling, measured with powertop 6W
600E PII/366 Debian Lenny/2.6.21 gnome Min brightness, laptop-mode-tools enabled, fan on, idling, measured with powertop 7.5W
