ACPI power state detection (PowerMizer)
I have a question: how does the nvidia driver detect power state changes?

The following always lists 0 (AC power); any ideas what might be wrong?

nvidia-settings -q GPUPowerSource -t
(I'm running debian wheezy on a lenovo T410.)

OK, so I've found out that the power source does get updated, but not for perhaps 10-30 minutes. I've attached an nvidia-bug-report, but it's too big when compressed with gzip or bzip2 to be accepted, so it's lzma compressed (rename, then unlzma should restore it to a text file).

Someone else with the same symptoms, albeit a rather older driver version (185): http://www.nvnews.net/vbulletin/showthread.php?t=133555
