That's because Lenovo recommends that your battery be charged to only 50% to increase battery life. What a laugh! Lithium batteries must be kept at or as near as possible to 100% for as long as possible to maintain good battery life. I tell everyone who cares about battery life in modern appliances that a Lithium battery should never be allowed to dip down beyond 50% charge. (I have an HP iPaq 951a which had its battery replaced in 2004 and still works well, because it's kept charged to 100% all the time.) The only thing that Lenovo users get by following their recommendation of keeping the battery charged to 50% is the privilege of purchasing a new battery from Lenovo every few years.
