Your hw.acpi tree and verbose dmesg look alright on a very quick browse.  
No AE_* ACPI errors and battery initialisation looks good, assuming you 
have just one battery fitted of the two supported.

It's quite possible that there's no problem.  Li-Ion batteries are not 
trickle-charged like older technology batteries (NiCd or NiMH) but after 
a full charge gradually self-discharge over days, perhaps weeks while 
the laptop is powered, until the battery gets down to below around 95% 
(on my Thinkpads anyway), when it will get boosted back to 100% again.

My X200 is down to 95%; I'm expecting a charge cycle any day now :)

State:                  high
Remaining capacity:     95%
Remaining time:         unknown
Present rate:           0 mW
Present voltage:        12418 mV

Try unplugging power and watching with acpiconf -i0 until down to say 
90% or lower, then reconnect power; it should charge up to 100% again, 
and stay up around 98-99% for a while before gradually dropping.

If it doesn't, try reporting the result of acpiconf -i0 at different 
states and times; just the lines above will do, except for the first.

And don't forget to let it run on battery sometimes, it's good for it; 
occasional deep (or even complete) discharges help keep the battery's 
internal 'coulomb counter' in good shape, and don't hurt battery life.

cheers, Ian
