KDE battery monitor gone and whining about ACPI not installed properly.

[Rich Lott]

I'm using a Dell C640 laptop.

Long ago under Debian/testing and XFree86, I could suspend to ram and I could 
also power-off. This was using APM.

Kubuntu Dapper installes with ACPI, which gave me problems (freezes on 
resuming from suspend-to-ram). I tried changing to APM but then it wouldn't 
power off - just sat there telling me that the system will now halt. AND it 
didn't solve the suspend-to-ram problem either. So I decided to try to switch 
back to ACPI.

But I think I've managed to break something because my battery monitor is gone 
and in the "Laptops & Power" bit I'm told "Your computer seems to have a 
partial ACPI installation".

I found that doing 
$ dpkg-reconfigure acpi-support
and restarting X made it come back.

But then it went away again on reboot.

Any suggestions for getting a full ACPI thing back? Or for getting APM to work 
fully?

Anyone with a C640 that's got anything working?(I realise that's a bit of a 
separate point)

thanks,
