Something else has happened to the charging circuit in the questionable LT. Some adapters have two voltages, one for charging and the other to run the unit. Dell uses a similar arrangement. It means you have to go back to the mfgr to get the proper adapter, an off the shelf won't work. The difference between the adapters tells me that the units are not exactly the same.

Things just don't sound tight. Charging a battery with a specific voltage and current will take a certain amount of time. A lower wattage adapter would just take a little longer to fully charge. Many laptops have a small board mounted right at the adapter connector that switches from battery to adapter and charges the battery. When they go bad, they can destroy(overcharge) a battery, fail to charge at all or power the unit without the battery.
