Power measurement clarification

Greetings,

In the ACPI spec there is a section (10.4) on power meters. Can someone clarify what these meters physically are? Are they external devices or onboard chips? If they're the latter, how can I detect them and read their data in userspace?

Regards,

Ken

To follow up on my last email, I have done some more research and it would appear that these are onboard devices that are presently not common in consumer devices.

( If anyone has more information on how to get power consumption data from standard desktops/laptops without the use of external measurement equipment, I would greatly appreciate it)

Regards,

Ken
