Stuck MacBook Trackpad Bulging Battery

If you have a MacBook or MacBook Pro that’s a few years old, you might have a problem hiding right below your fingertips. If your trackpad has become difficult to press, or stopped clicking all together, you could have a dangerous faulty battery. In MacBook & MacBook Pro laptops, the battery is directly below the trackpad. When the battery fails it can expand, pressing into the bottom of the trackpad.

Explosion?

I’m not sure quite how risky these batteries get, but they almost double in size. Standard battery advice says don’t pierce or burn but when these battery start expanding they could easily get punctured. I saw one so bad last week that the bottom case and trackpad were being pushed apart. (see photo below)

If you click the battery 🔋 icon near the clock at the top-right of your Mac screen you can check the status. (If you don’t see the status, press the option (alt) key before clicking the battery icon.)

From Apple’s help document

You may see any of the following conditions:

  • Normal: The battery is functioning normally.
  • Replace Soon: The battery is functioning normally but holds less charge than it did when it was new.
  • Replace Now: The battery is functioning normally but holds significantly less charge than it did when it was new. You can continue to use the battery until you replace it without harming your computer.
  • Service Battery: The battery isn’t functioning normally, and you may or may not notice a change in its behavior or the amount of charge it holds. Take your computer in for service. You can continue to use your battery before it’s checked without harming your computer.

What Next

If your status shows Replace Now or Service Battery, I would look to get the battery replaced as soon as possible. At the very least, a bulging battery could cause cosmetic damage to your Mac. At worst it could potentially leak or catch fire 🔥.
