11 If it’s an Intel laptop, check powertop. It will tell you all sorts of
12 causes for power usage, including interrupts, display, different chips,
13 their sleep states and so on. Also check whether your CPU can reach the
14 deepest C-state available. I’m not sure how much the tool helps on an AMD
15 system, since I don’t have one yet.
17 Anecdote: when I bought my passively cooled mini-PC with an Intel N5100, it
18 drew 10 W from the socket. I was a bit disappointed, because I knew it could
19 do less. Powertop told me that it remained at C3 and did not enter C6. I
20 checked for a BIOS upgrade and – sure enough – there was one and the
21 changelog said something about C states. After the upgrade, C6 was available
22 and power draw decreased to 6..7 W.
