I've noticed over the past few weeks that occasionally my magsafe on the ACD does not charge my Macbook Pro. Sometimes I look and the light on the magsafe is off, but when I look at the computer the computer indeed recognizes that it is connected, but it won't charge. If the battery is below 95%, and the magsafe is connected when the light is out, it just says "not charging". So basically the magsafe is being recognized by the computer but just not doing its job of charging the machine. It is an intermittent problem, and my Macbook Pro magsafe charges every time without fail, so I know it's an issue with the ACD's magsafe. Curious to know, has anyone else experienced this or possibly talked to Apple on this and what did they say? Being an intermittent problem and being five hours from an Apple store and being a large display I'd prefer not to go there unless absolutely necessary.
