So it looks as if the battery is OK, but it is not charging properly. I obviously have to take it to be repaired - but what can they do? I understood that they can't replace the battery, so what are the options? It has only been through 377 charge cycles - that doesn't sound a lot to me - but is it? Shouldn't a laptop that's only just over 2 1/2 years old still have a perfectly good battery??
