Is that a bulge in your battery, or…?

Multiple Choice Quiz

If your first generation MacBook Pro’s mouse click pad stops working it’s likely because…

A) The clicker is physically broken
B) The mouse software settings need resetting or adjusting
C) The battery needs replacing

    If you picked C, you’re right. How the heck can the battery affect the mouse?!? I didn’t get it immediately either. Introducing… battery bulge.

    The genius at the SF Apple store Genius Bar diagnosed my ailing MacBook Pro without hesitating: battery bulge.

    powerbook.gifIn MacBooks, the battery is located beneath the mouse pad. The battery, manufactured by Sony, had been recalled months ago. I remember checking the model number on the battery and determining that my battery was not amongst those recalled. So I did nothing.

    When these batteries get too hot, they will split open, or bulge, and in some cases the battery acid will leak out. Fortunately, that was not the case with mine. The battery had started to split at the seams and was pressing on the mousepad from below, which caused the mouse clicker to malfunction.

    Apple replaced the battery for free, and the mouse clicker was working again. Try that on for size, Diagnosis X.

      My Krzr cellphone battery developed a bubble when it went bad. Verizon wanted me to spend $44 or 50% of the cost of the phone to replace the battery – i bought mine online instead for $6 delivered!
