I subconsciously move it in planes parallel to the lie of the lever in the rest position, picking it up to move it perpendicular as necessary. :) > Did you remove the cord from the back or just the wall? I'm always removing the cord from the back of the machine, never from the wall. > Assuming it's like the wallstreet in this regard, the lights stay on while > the battery is charging to indicate the charge status.

That's what I was guessing it was doing, but it doesn't always stick to this plan, so I was confused. > Again, based on the wallstreet's behaviour, sometimes the battery gets > confused.

I had a wacky idea today: Maybe when I unplugged the machine from its wall supply, the battery had worked its way either (1) away from the contacts inside the bay or (2) into a state of denial, where it was fully in the bay but the machine didn't know it. In this case, perhaps the PowerBook can handle five minutes on a small internal battery before dying. I figure if I was the one implementing this feature I'd throw a message to the operating system that you had a short period of time to get power back (like putting in a new battery)... being that Linux isn't getting any support or attention from the PMU people maybe it's doing this. This would be a great feature for someone swapping batteries while keeping the machine on (and while away from an outlet, like on a plane) but would add lots to the weight and cost, I'd think. This is just a wild guess on my part, and Ben or Paul probably know much more about this than I do, but it's almost consistent with the situation, given that this magical internal battery exists. :) -- Shaw Terwilliger (sterwill@io.nu) ** Sent via the linuxppc-dev mail list.
