My MBP is just out of warranty (29th March) and had the logic board replaced two weeks ago at the local apple store due to buzzing/whining when bluetooth was enabled. The battery took a sudden drop in capacity on Friday from around 5200Mah to 3300Mah according to coconutBattery. This is the second battery after the original was replaced in August under the recall after a similar problem. It's got approx 130 cycles on it. Calibration hasn't helped. Are Apple likely to entertain replacing the battery again considering it was only in a couple of weeks ago and the battery is 6 months old???
