A power meter. My summary so far: my goal is to measure power consumption of my Thinkpad, and be able to read the consumption details from Linux. Right now, I can only supply the Thinkpad with 5V@2A when the CT-3 is used, while the Thinkpad would also support 20V@3A. (Forum thread) Also have not yet succeeded in reading the values from Linux.

I want to see how much power for example the Thinkpad uses, and how accurate the internal computation from powertop is.
