[arch-general] Weird behaviour A/C vs battery

[Manolo Martínez]

Hello everyone,

I would like to ask you for help with a weird piece of behaviour of my 
arch box (now 3.0, but it was the same with older kernels):

* Shutdown works OK when on A/C, but, when on battery, the computer ends 
up with fans on and the On button light on. In this state it is totally 
unresponsive -- it looks much as it does when it fails to suspend.

* But, on battery (and A/C too), it reboots perfectly well. So I've 
resorted to rebooting when I want to shutdown on battery, and then 
plugging it off once it gets to the bios screen.

I'm sure these will be tell-tale symptoms to more enlightened arch 
users. For my part, I am totally clueless. I would have suspected an 
acpid problem, but I have no shutdown event or action enabled. I don't 
see anything interesting in the logs either.

Any piece of advise will be very welcome.

Cheers,
Manolo
