My CPU scales from 800MHz to 4.8GHz, obviously in a vastly different power envelope. I have an applet that tells me what speed it's running at on my panel and today I've noticed that it's running pretty close to the top end all the time. Even when it's essentially idle. $ uptime 22:05:34 up 1 day, 5:37, 1 user, load average: 0.00, 0.00, 0.00 I'm running on the "powersave" governor (intel_pstate driver). So —short of closing random processes until it tweaks down— how do I go about finding what's stopping my CPU from underclocking? Some follow up from the comments.
