What kernel are you running?  HAL should just be taking its cues from
hotplug and from /proc/acpi, so if the kernel doesn't recognize that
you've plugged in the AC adapter for a while, neither will HAL...

A way to test this:

1) Start with AC adapter UNplugged
2) run the command:
      watch -n 1 "cat /proc/acpi/ac_adapter/AC/state"
3) It should say "off-line"
3) plug in ac adapter
4) See what the 'watch' does, it should say "on-line" when the
kernel/acpi layer realize the adapter is actually plugged in

If this takes more than a second or two, something is either wrong in
your kernel, your BIOS, or your BIOS is just wierd.

What laptop model and BIOS?
