Hello,
i would like to make some notes about this laptop, maybe it applys to other lifebooks or laptops as well.
There are 3(actualy 4) states of Cstates.
| Code: |
tuxu mardicas # cat /proc/acpi/processor/CPU0/power
active state: C0
max_cstate: C3
bus master activity: 00000000
maximum allowed latency: 2000 usec
states:
C1: type[C1] promotion[--] demotion[--] latency[001] usage[00000029] duration[00000000000000000000]
C2: type[C2] promotion[--] demotion[--] latency[001] usage[00002168] duration[00000000000001644047]
C3: type[C3] promotion[--] demotion[--] latency[017] usage[00055558] duration[00000000000732598140]

When linux goes to C3, then it starts to make a noise, i managed to fix this by setting the max_cstate=2 bootflag. But i still would like to know if this sound is generated with windows too? Any fixes to this?
Another funny thing happens when i use the dock. If i insert the laptop to a doc then the noise stops(C0) because it charges, when i remove the laptop then ACPI does not realise that it is not on AC anymore. Therefore stays on C0 and thinks that it is on AC.
ON BATTERY, now pluging in the power cord.

IN DOCK, now removing laptop from it

Any ideas? Why is there no ACPI event?
