  • Page 87 Hardware/Software Interface 4.2.1.15 Operating Hours Counter This command allows querying the operating hours counter. The operating hours counter counts the number of hours and minutes the board has been (at least partly) powered on, i.e. when the system is in S3 or S0 state. S0 to S5 are the power states as defined in the ACPI specification, or an equivalent state.
