I foolishly thought things wouldn’t get any worse than the entire system shutting down (not even locking up, but shutting down, and not through the OS, just, boom, dead) on any ACPI call, but I was wrong. It turns out that the battery doesn’t charge unless the power cable is plugged in AND the laptop is off. If the machine is on, the power cable won’t be used, and the battery will just drain.
Gee, that’s the best $700 motherboard I’ve ever been forced to purchase..
My laptop is useless right now. The work I planned for Galago and the notification stuff this weekend will not get done, and I won’t be available for contact much until after next week (assuming IBM can get it right this time.)
Update: Tacking on another wonderful issue. The laptop just stops recognizing the keyboard and trackpoint randomly, requiring a complete shut down. Unfortunately, the On/Off button, which you normally hold down to force a shut-off, doesn’t seem to always work, especially not when the keyboard isn’t working, so you have to pull out the battery.
