The (relatively new) charger works fine and powers the laptop fine - a green light is on when connected but the battery won't charge.
Here is the information. Can anybody help?

Your battery has as much life in it as Ossama Binladen.  You need a new one which can be installed at an Apple store.  1241 cycles is more than one can reasonably expect.  Though you may operate your MBP with the power adapter, the performance will be slowed down by the OS until a new battery is installed.
