Most likely the battery has died or is no longer being recognized by the system. To verify it is not the latter Apple has a KB article that will help with resetting the SMC. If it is the former it's time to replace the battery. If you are under warranty take it to a nearby Apple store. If not they can still do the repair but it will cost you. Depending on ...

No. 5-7 days is way less than an extended period of time @FoamyBeer refers to. Imagine that a lot of devices stay in warehouses longer than the time you want not to use your MBP. Just handle it as if it was a book: Don't drop it Neither heat nor freeze it Keep it dry In addition to that, do NOT leave it with a discharged battery. Actually, it's no big ...

I have a MacBook Pro (13-inch, Mid 2010) and the battery cycles counts more that 1100. Maybe I'm lucky, but I never change the battery and I think is working very well. (The System Information report a Condition that is Normal!) After the 1000 cycles the battery probably start and continue to decrease a bit the Full Charge Capacity but you can still use it. ...

Well, shave my whiskers, crumble my biscuit, and oil my gears, I'll be darned! I let it sit there in that state for a literal hour (72 minutes) with no progress bar or evidence of activity [even over USB 3.0!] and it eventually restored and booted.

It is, to the best of my knowledge, complete nonsense that on a newish macbook pro and air, that keeping it plugged into the wall damages the battery. It was the case on older pc laptops, and most probably older macs too, but the newer macs are intelligent enough not to keep pumping power into the battery once it's charged. Once the battery is fully ...

Apple's advice if you're storing a device for extended period of time, is: do not fully charge or fully discharge your battery, but charge it around 50% Power down the device Place in a cool moisture-free environment that's less than 32° C (90° F)

Constant charging should not damage the battery in an extreme manner. Yes, you would get more life from it if you would let it always cycle between 40 and 80%, but the Mac is already cycling power in the high 90s even though it is not showing it to you. I have not been cautious at all with by 2009 Macbook Pro and I can still get around 2 hours of autonomy ...

This means your MacBook does not recognise the battery. Maybe it's not installed properly? https://support.apple.com/kb/PH18598?locale=en_US
