While the computer is turned on, the Idle, Run, and Turbo states are
transparent to you. The operating system handles switching among these
states.
Note that current consumption varies greatly with processing load,
especially if a radio card is installed. Values shown assume the CK30 has
just completed a cold boot.

at 8V)
N/A Main battery out, supercap fully depleted.
<3mA Supercap fully charged. If the supercap is
depleted, this current can be as high as
70mA. As the supercap charges, this
current steadily declines.
N/A Current consumption depends entirely on
what devices are left powered during
Suspend (See the "System Power States and
Transitions" table in the next section).
N/A The operating system switches in and out
of the Idle state too fast and unpredictably
to make any typical current measurement
repeatable.
