Yes, it's just like like the battery got yanked out (which I've done once; just once! The Lombards have that bay release lever in the ultimate "shirt-catching" position). I know both times the machine shut off without warning, I was nowhere near the lever. Once it was just sitting on a table, once in my lap. > Then, the same thing started happening with linux... I don't run MacOS on this laptop, so I don't have a frame of reference that includes MacOS's power management. I was assuming my problems might be related to a 5-minute "no more wall power!" PMU signal Linux might be mis-handling. I really haven't timed the delay before the outage; maybe today I'll just remount root ro and watch the clock. > It gets to a point where I can't get the machine to boot again without putting the power plug back in. I've never had this problem. For me the only problems are when the machine is booted from the wall, then pulled and used with the battery (full power, all four lights on the status thingy). > I haven't tried this out yet...I almost always boot it with the power in. Perhaps I'll try this. I usually use my PowerBook with the power adaptor instead of the battery, because I'm usually in a comfortable chair at home, and because I really, really don't want to sit through a fsck of a 6 GB laptop drive if I take it out somewhere. :) Something else for the experts: I'm not sure how to read the status lights on my battery. - When it's booted from the wall, with the battery in, usually the "normal" things happens: the battery lights are off until I hit the button, then they come on for 4 seconds and go off. - Sometimes, like when I unplug it from the wall, and then plug it back into the wall, the lights will come on and stay on for minutes. Pressing the button does nothing. I'm assuming this is a short "charge" stage... maybe not. - Sometimes, when it's been plugged into the wall for a long, long time, and there should be no charging needed, the lights will also stay on for minutes or hours at a time; pressing the button won't turn them off. -- Shaw Terwilliger (sterwill@io.nu) ** Sent via the linuxppc-dev mail list.
