A MacBook mystery: Why isn’t this new battery working? – seattlepi.com (blog)

A couple of weeks ago, my wife got a notification on her MacBook Pro that said “Service Battery”. If you inspect the recommendations files for OS X, you discover this explanation:

Service Battery: The battery isn’t functioning normally, and you might or might not notice a modification in its behavior or the quantity of charge it holds. Take your computer in for service. You can easily keep on to usage your battery prior to it’s checked free of harming your computer.

 
Her Mac is regarding 6 years old. It’s a mid-2010, 13-inch model, the initial of the unibody MacBook Pros that don’t contain an easily removable battery. That doesn’t mean the battery can’t be replaced, yet you have actually to open the case to do it. Apple says it’s not “user serviceable”, yet replacing it is a fairly trivial thing to do, as this video indicates.

While the “Service Battery” notification doesn’t necessarily mean she requires a brand-new battery – there are “Replace Soon” and “Replace Now” status messages that could appear – I decided that, due to the fact that this computer was very old, I’d go ahead and swap it out.

I could have actually bought a third-celebration battery online and saved fairly a bit of money, yet commonly those are knock-offs that don’t last long and, in some cases, can damage your MacBook. Instead, I opted to buy a actual Apple battery from iFixit, the homeowners known for their teardowns of electronic products and detailed repair manuals, for $99.

The battery arrived a couple of days later and I installed it, which took only a couple of minutes. yet as soon as I did, it didn’t job as I expected. Here’s just what happened:

  • The MacBook Pro would certainly not turn on unless the AC adapter was connected to it. as soon as I removed the MagSafe connector, the computer blinked off.
  • Normally, the MagSafe adapter’s indicator light shows green as soon as initially connected, after that switches to orange to indicate the battery is being charged. as soon as it’s fully charged, the light turns green again. yet in this case, the light stayed green.
  • Battery indicator showed it was 47 percent charged. yet it likewise said “Not charging”, and no matter exactly how long I left the adapter connected, the indicator stayed at 47 percent.

 
I put her old battery spine in, and it worked fine. It charged, the MacBook Pro could be powered off the battery, and the indicator prove to charging progress. It still said “Service Battery”, though.

I contacted iFixit via support email and explained the issue. This was on a Saturday afternoon, and I got a response the next day, although iFixit’s contact details says weekend queries won’t be answered until Monday. (Kudos, iFixit, for the terrific service!)

Joe, the tech, suggested I do several points along with the brand-new battery installed – run a Repair Permissions (or Disk initial help on OS X 10.11, the version on my wife’s Mac); reset the NVRAM, a memory cache that stores some settings; and reset the SMC, which controls hardware configurations on the Mac. I tried his suggestions, yet none worked.

He likewise asked me to send him or her some screenshots if those failed. Joe had me install Coconut Battery, a superb (and free!) battery diagnostic for OS X, and screenshot that too as a capture from the Power tab on the Activity Monitor. right here are those screenshots.

One interesting thing to note from the Coconut Battery results: The brand-new battery is 1,461 days old, or four years. That’s not necessarily surprising, due to the fact that this is an old model and Apple probably isn’t making fresh ones. Joe assured me this particular battery had been bench-tested prior to it was shipped, and it tested well.

I’m still waiting to hear spine now that Joe has actually these screenshots. yet this is an interesting puzzle. What’s going on here?

There are a couple of possibilities:

  • The brand-new battery is defective. That’s the simplest and mostly most likely explanation, yet the truth that iFixit supposedly tested it prior to it left their warehouse is a caveat.
  • The logic board or energy converter on the MacBook Pro has actually problems. yet if this was the case, I would certainly believe the old battery wouldn’t work, either. That is, unless the problem manifests itself in the old battery along with a “Service Battery” notification, yet along with the brand-new battery, the symptoms are a lot more acute.
  • Something else I am not interested in or learning is going on.

 
It’s rather feasible that I ought to have actually bit the bullet and taken my wife’s computer to Apple for a look-see. I might have actually assumed also considerably by merely replacing the battery. And I might yet end up carrying out that.

I’ll update this blog article as soon as I have actually a resolution, yet in the meantime: just what do YOU believe is going on? permit me already know in the comments, or reply via Twitter.
