Hey everyone, So, I just picked up a new 12.9. Last night, after running the battery down to 12%, I plugged it in to charge using the supplied 12 watt adapter and cable. When I plugged it in, I noticed it didn't "chime" as it normally does but the charging indicator appeared next to the battery icon. I left it charging for about 2 hours. When I checked on it, nothing had changed. The battery level was still 12% and the charging indicator was still there. So, I unplugged the cable from the iPad and reconnected it. This time, it did chime and again the charging indicator appeared. It then charged the battery up as normal. What puzzles me is why did it show the charging icon, but not charge the battery? Just curious if anyone else has experienced this. Thanks!
