Hmm ... I am now unable to reproduce the high power consumption myself. :P
While I don't have a power meter (wish I did ;), I have been using a hack that
guesses the power usage by measuring battery charge before and after suspend.
The hack lives at
http://www.thinkwiki.org/wiki/ACPI_sleep_power_drain_test_script
Some months ago I had used this script to estimate S3 power usage, and I seem
to remember finding that S3 power dropped when I undocked the ultrabay, by
0.5-1.0 W or so. But then I ran out of free time so I couldn't file a bug
report right away. Since then, I assumed that if the LED was still on, then the
power drain was still there. I now see that this assumption seems to be
incorrect. The aforementioned script now suggests a 0.8 W drain during S3,
regardless of whether the drive is docked or not.
So it seems that I must have misinterpreted the results the first time around.
Either that, or the power drain has been fixed since I last checked, in which
case, great work guys. :) Sorry about the noise.
