Early MacBook Pro batteries not working well

I don’t have a lot of sympathy for them, but it’s been a rough week for Apple. First, the thermal paste inside MacBook Pros was applied too liberally, causing the machines to run too hot. Now, some batteries in the MacBook Pro aren’t working correctly and have been recalled. Any MacBook with a serial number up to W8608 is affected, which are the earliest batch of the batteries made in the first two weeks of production. If you have one in that group, Apple will send you a new battery if you contact them, though they don’t seem to be loudly trumpeting the problems or the solution.

“Symptoms of a MacBook Pro battery problem include: power level going from a full charge to 90 percent, then immediately off. The battery usually either goes straight to one blinking LED or won’t respond at all. Some may experience a significant loss of battery capacity as well.”
