That's because powertop sometimes can't get reliable per-process
wakeups. I guess that in this case, the battery plugin uses ACPI, and
ACPI causes the wakeups. I also have the case where the wireless LAN
causes the graphics card to show up in powertop, which is just wrong
IMHO. So I just use the total wakeups/s for my calculations. I know
that they depend on the rest of the system, but I try to keep that in a
defined state.
