Default A normally working Thinkpad, that isn't

That's not normal. Three reasons off the top of my head - there was a problem with the battery, in which case reporting it during the first year would have allowed it to be covered under the warranty, the power management settings on the computer are set in a way that it's using more power, or there's software on the computer that's causing a lot more system activity and using more electricity (peer to peer software could cause this - the hard drive would never spin down, more network traffic, etc.)

I can get almost 3 hours with modest power management settings on a 5-year old Thinkpad R40 with a battery that's almost 3 years old and only has about 80% of its original charge capacity.

I'd expect to only get an hour or two out of a four year old battery. Lithium ion batteries deteriorate - there's no way around it.
