My apologies if this issue has already been discussed, I tried searching but found nothing. I bought a new 24" LED Cinema Display today but once I got it home I found that it doesn't want to charge my MacBook's battery. It said "Not Charging" when I clicked the battery icon in the menu bar but I really thought nothing of it. Then, while I was transferring files from my external HDD to the MacBook everything just turned off completely. I feared the worst and when I tried booting my MacBook it simply would not turn on. It seems like the Cinema Display had bled my MacBook dry - it had no charge in the battery and I had to do an NVRAM reset to get it to charge again over the power adapter. Still when I connect my Cinema Display to the Magsafe it does not charge the computer, yet it does charge fine when I connect it to the MacBook power adapter. Seems like a faulty Cinema Display to me, but it was an 80 mile round trip to the store to buy it, I don't really want to have to go back. Has anyone else had this problem?
