Supercap fully charged. If the supercap is 
depleted, this current can be as high as 
70mA. As the supercap charges, this 
current steadily declines.

The operating system switches in and out 
of the Idle state too fast and unpredictably 
to make any typical current measurement 
repeatable.

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.
