Interesting, things change slightly after this:

/*plugged in */
jaywink@jaytec: pts/5: 24 files 828Kb -> acpi -abi
Battery 0: Full, 100%
Battery 0: design capacity 6100 mAh, last full capacity 5900 mAh = 96%
Adapter 0: on-line

/*unplugged */
jaywink@jaytec: pts/5: 24 files 828Kb -> acpi -abi
Battery 0: Discharging, 100%, 03:39:19 remaining
Battery 0: design capacity 6100 mAh, last full capacity 5900 mAh = 96%
Adapter 0: off-line

I guess that kind of is better. If I change the value back to 1000 which it was before, the following happens:

/*plugged in */
jaywink@jaytec: pts/5: 24 files 828Kb -> acpi -abi
Battery 0: Unknown, 98%
Battery 0: design capacity 6100 mAh, last full capacity 5900 mAh = 96%
Adapter 0: on-line

/*unplugged */
jaywink@jaytec: pts/5: 24 files 828Kb -> acpi -abi
Battery 0: Discharging, 98%, 03:46:44 remaining
Battery 0: design capacity 6100 mAh, last full capacity 5900 mAh = 96%
Adapter 0: off-line

Anyway, even with acpi correctly saying whether it is discharding or charging, Ubuntu battery indicator doesn't notice the change. Anyone know how to trigger it manually?
