Hi,

afaik, Dell is known for bad DSDT's. A solution is to have a look at the acpi 
project on sourceforge for fixed DSDTs. They have a small howto on convincing 
the kernel to load your patched acpi image instead of the system one.

another thing would be to look in your /proc/acpi to check out if you have a 
subdir "battery". if not try the following:
modprobe battery
modprobe ac
modprobe processor (in fact, you should load all the modules in 
/lib/modules/2.6_blah/kernel/drivers/acpi :) as they are not loaded by the 
"acpid" in startup.

Then everything should work ok. I have an X200 and had loads of fun with this 
over the w/end :) (not).

Cheers,

Laur
