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. |

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. |
