IBM ThinkPad T42 ACPI issue (continued)

Hi Len, I have noticed something interesting. I didn't take notice but when you shut the laptop down forcefully after ACPI is supposed to turn off all devices. I noticed that one of the wireless devices on the laptop is still on. You can hear buzzing coming from one of the FCC devices. When the battery is shorted (removed) the system is completely 'off'.

If ACPI isn't fully shutting down devices wouldn't holding the power off button for the normal 5 seconds shut the whole thing off completely?

Also, is there any patches I can test?

Thanks

Shawn.
