This is intentional. The Thinkpad doesn't charge batteries that are close to full capacity. It goes something like this:
100% charge
removed from A/C for 10 minutes
98% charged
plugged back in
Will not charge until battery drops below threshold (which lowers as battery ages)
remove from A/C for 1 hour
70% charge
plug back in
Charges to 100%.
The threshold for a new batter is around 95% as I recall.
