I’ve had my MacBook Pro for nearly a year now and I’ve not had any problems with it. Recently, however, its started powering down without warning whilst running off battery. This usually happens when the battery is at about 40% – not particularly unusual!!
After a quick Google, I found that Apple have recalled some MacBook Pro batteries. The affected batteries have model number A1175 and a 12-digit serial number that ends with U7SA, U7SB or U7SC. These match the battery I have.
Full details of the replacement program for these batteries can be found at:
I filled in the details on the web site for a replacement and got an email back saying it would be replaced within 3 to 5 working days – much quickier than I was expecting.
Hopefully the new battery will fix these random shutdowns I’ve been experiencing.
