Actually, today with
	VGN-Z11
	linux 2.6.36-rc6
	patch for idle nohz
I cam down to *below* 8W, but this was lowest brightness, bluetooth,
wlan, wwan soft kill switch off, but programs running:

Cn                Avg residency       P-states (frequencies)
C0 (cpu running)        ( 1.1%)       Turbo Mode     0.0%
C0                0.0ms ( 0.0%)         2.54 Ghz     0.0%
C1 mwait          0.0ms ( 0.0%)         1.60 Ghz     0.0%
C2 mwait          0.3ms ( 0.8%)          800 Mhz    99.9%
C6 mwait         16.7ms (98.2%)

Wakeups-from-idle per second : 81.3     interval: 15.0s
Power usage (ACPI estimate): 7.9W (11.0 hours)

Top causes for wakeups:
  23.8% ( 18.1)   kworker/0:0
  14.0% ( 10.7)   [ahci] <interrupt>
  13.4% ( 10.2)   [kernel scheduler] Load balancing tick
   6.6% (  5.0)   syndaemon
   5.5% (  4.2)   Xorg
   5.5% (  4.2)   [extra timer interrupt]
   4.6% (  3.5)   [acpi] <interrupt>

That is something I like.

Best wishes

Norbert

KIRBY MISPERTON (n.)
One who kindly attempts to wipe an apparent kirby (q.v.) off another's
face with a napkin, and then discovers it to be a wart or other
permanent fixture, is said to have committed a 'kirby misperton'.
