There is a problem that the chip manufacturers must scale down the the voltages 
to fit the ADC converters to its range. Problem is that the manuf. are free
to choose whatever resistors for scaling.

If you use acpi, please can you send us the dsdt.bin
file?

You can obtain it via cat /proc/acpi/dsdt > /tmp/dsdt.bin

Thanks,
