Bulge in Bottom Case of Macbook Pro 10,2

[Vandal.]

Hey guys,

after five years of service I noticed my first hardware issue on my early 2013 Macbook Pro (10,2)—the bottom case is bulging out. Not hugely, just enough so it doesn't sit flush on my desk anymore. The bulge is to the left of the case:

I ran system diagnostics which came up without any issues and system report looks good as well, no issues with battery or hard drive. The Macbook does run a bit hotter than it used to in the last years, but not overly.

I'm still worried to open it up as I read about batteries causing these bulges and are popping open etc. once the pressure from the case is lifted. Is this likely if the system comes up perfectly fine?

Thanks in advance,
V

It's very likely you have an expanded battery. Stop using that Mac immediately and have it replaced ASAP.

Seconded.

Or possibly a huge infestation of spiders. But I'd guess a battery too.

Two reasons to hurry up and replace. Safety, and the bulging battery can ruin the trackpad, too.

Get it replaced!

Agree with the others and the only thing that can bulge is going to be the battery. It is a fire hazard at this point so I would not longer charge it. It can also damage other things in you laptop just from the battery expanding.

Understood, replace battery with expanding spiders.

Jokes aside, I'll get a new battery installed. It's weird though, wouldn't an expanding battery also come up as faulty in diagnostics? It's a bit odd that there's nothing indicating a faulty battery in the system itself…

The diagnostic programs are not perfect. Your laptop is proof.

As others have said, it's the battery.

An "expanding" battery is a fire hazard.
Get it replaced as soon as you can.

Take it to a brick-n-mortar Apple Store and show it to them.
They just might replace it for free.

Even if they don't, the replacement will run about $200 and it's worth spending the money on.
Again -- you don't want to keep using it that way, because it's a fire hazard.
