Hey there guys! just owned a Late 11' MBP 13" ...Really gorgeous device...but having a problem with the battery ...Left it downloading Mavericks last saturday but when saw it on sunday, battery wasn't charging, and did not recognized the charger for a long while. Then yesterday it was off all the day long and took charge at night but when I unplugged it wouldn't want to charge again. I'm looking for support guys, please...
