C3 State Not Detected/ Pentium M

C3 State Not Detected/ Pentium M

[Joey Crivello]

Hey all,

I have a Sony Vaio Z1-VA with a Pentium M 1.6 GHz CPU, and my ACPI 
package is not detecting the C3 power state (which I'm almost sure the 
P-M has... I might be wrong though?)

I don't know exactly what information is needed to troubleshoot my 
problem, so I have included quite a bit of output below from some of the 
less verbose programs that were suggested on http://acpi.sourceforge.net/.

Thanks,

Joe Crivello

So does my VAIO Z1XZC 1.5G. From FADT, the C3 latency is 1001.
According to ACPI spec, C3 latency more than 1000 indicates C3 is
not supported.

Thanks,
