I see the same behavior with both of my pair of T42 (currently running 4.4-stable). [Yes, I know that's out of date. I pre-ordered the 4.5 CD set, and it's been on my desk for 2 months now. Maybe sometime soon life will be un-hectic enough that I'll be able to install it...] That this behavior also didn't change when I had to have the motherboard replaced in one of the T42 last month. Interestingly, I did *not* see this behavior with a T43p or on any of 2 different T41p, running various OpenBSD versions from 3.9-stable up through 4.3-stable: Each of these had a battery lifetime of > 30 days when in APM suspend-to-RAM state. (And that "> 30 days" may well be more a measurement of internal leakage current in the battery than actual power draw by the laptop.) Unfortunately, I don't have any of these machines available for comparison any more (I had to give the T43p back when I left that job, and both of the T41p suffered fatal hardware failures). I wonder what's going on here? ciao, -- -- "Jonathan Thornburg [remove -animal to reply]" <jth...@astro.indiana-zebra.edu> Dept of Astronomy, Indiana University, Bloomington, Indiana, USA "Washing one's hands of the conflict between the powerful and the powerless means to side with the powerful, not to be neutral." -- quote by Freire / poster by Oxfam
