Having a problem with my recently purchased refurbished 2017 15" MacBook Pro. Yesterday it suddenly shut down and after rebooting, I noticed the battery was at 1% despite being plugged in. Now if it gets unplugged, the system shuts down instantly. When I click on the battery icon in the menu bar, it says:

  • Battery Is Not Charging
  • Power Source: Power Adapter

No warning about servicing or replacing the battery. The interesting part comes up when I check the system information. Under power, it lists:

Charge Information:

  • Charge Remaining (mAh): 0
  • Fully Charged: Yes
  • Charging: No
  • Full Charge Capacity (mAh): 6736

Health Information:

  • Cycle Count: 4
  • Battery Installed: Yes
  • Amperage (mA): 0
  • Voltage (mV): 12904

The fact that the charge remaining is 0 but that it's still thinks it fully charged leaves me to believe that this is what is preventing it from charging properly. I've Googled the problem pretty thoroughly but everyone I've come across with a similar issue has Charge Remaining: 0/Fully Charged: No.

So far I have tried resetting SMC, different outlets & leaving it unplugged with the clamshell open all night in an attempt to fully drain the battery. Does anyone have any other suggestions short of taking it in for servicing? I bought this thing like 4 weeks ago so I'd rather not have to spend more cash on it already. According to the Apple website, this computer has had the battery recall issue taken care of already. Could the new one be calibrated incorrectly?

System Specs:

  • MacBook Pro (15-inch, 2017)
  • 2.9 GHz Quad-Core Intel Core i7
  • 16 GB 2133 MHz LPDDR3
  • Intel HD Graphics 630 1536 MB

Thanks in advance for any help you might be able to offer

  • You have a defective battery. It's showing that you have no current available (0mAh or zero mili-amp hours) and it's indicating it's fully charged. It also show it's putting out nearly 13V, but it has 0mA. That means it has a charge of 13V, but it has no "power" behind it. Given that it says only 4 cycles, it appears your battery is defective. You need a new one. – Allan May 28 at 18:41
