Does overcharging my MacBook Pro degrade its life?
You can't really overcharge your Macbook. Even with the computer shut down, the battery will drain very slowly (as all batteries do). But once your battery is 100% charged, the charger cuts down the current, just enough to keep the battery at 100%. Since the current usage goes down, so should the temperature of the charger, it should no longer be hot but slightly warm instead.This charging regime absolutely prevents overcharging, and also allows the battery to remain cool most of the time even if the AC adapter is connected. Charging heats the battery — an inescapable consequence of the laws of physics — and heat is an enemy to batteries, so it's highly desirable to avoid unnecessary heating.So you should not keep the charger connected at all times to let the charger and the batteries have some rest.
MacBook Pro Shut Down Unexpectedly and will not turn on?
My MacBook Pro will not turn on. I was just on my MacBook (purchased in 2013, brand new) when I went to click to close out of an internet tab. When I clicked there was like a pop sound and my MacBook turned off. Now it won't turn on. The battery is fully charged, and I have never dropped it or damaged it. There was no power surge or anything. I'm pretty pissed and ready to just buy a PC as I am done with Apple and their BS. So, can anyone offer advice to fix the computer. Also, how I can talk to the Apple associates when I go to the store so I don't have to pay for any repairs because it is only a year old and I paid 3k for it.
How do I know my 2016 MacBook Pro is fully charged when I charge it?
Sadly, there’s no way to do this anymore unless you see the battery percentage bar at the top right corner on your screen.Yes, before we can do this through the color of the light on the magsafe (All Macbook up till 2015), or through the battery indicator lights available on the left sides of a MacBook Pro (non retina).Luckily, if you’re running OS X Sierra and connected to the internet, you can ask Siri. First, you need to activate hands-free Siri. Here’s the tutorial:
How can I stop my MacBook Pro 2012 from shutting down when the battery is fully charged?
My answer will almost certainly not be the best answer here, but I had the same issue with my Macbook (earlier year than yours.)Firstly, if you can - take it to Apple Care. This is probably your best bet, especially if you live in the U.S. it can make life significantly easier.Secondly, what I did to rectify my similar situation:Perform a clean re-install of the OS This is a shot in the dark, but what I ended up doing to fix the situation was open the entire thing up and take out lots of the internals - especially paying attention to cleaning the inside (with compressed air and a cloth) as well as doing a good old clean on the battery contacts. Have you done a battery health check? This will help everyone find out how to better answer your question.
Does the new MacBook Pro charge when it's off?
I got the 13 inch retina one. When I plugged it in when it was off, the light on the charger Didnt come on. But when I turned the computer on, it instantly started charging.
My 2012 MacBook air shuts down everytime the power cord is disconnected, why is this happening?
Your laptop can’t hold a charge anymore. It will only work when plugged in. You can ether spend $400 on getting your battery replaced by Apple or buy a new MacBook. The cheapest one right now starts at $999
Why would a MacBook Air shut down when battery reached 29%?
Click on the little Apple icon in the upper left hand corner. Pull down to "About this Mac" and open it. Now click on "System Report" and once you've done that, in the left hand column, find "Power" and click on that.About half way down the right pane, you'll find a heading "Health". Under that, you'll see two things: Cycle count, and Condition.You get about 1000 cycles out of a lithium ion battery. If you're approaching that, you're due for a new one. Unless you're a massive power user, that's about a four to five year trip.If your "Condition" doesn't show "Normal", you're due for a new battery.BTW, the 2013 MBAs don't have a glued-in battery, this is about a 20 minute job for someone that's done it before. If you're under AppleCare, they can do it at the Apple Store. Actually, even if you're NOT under AppleCare they can do it at the Apple Store - or I can make some alternative suggestions in the Portland area.
MacBook Pro's charger's light changes from green to orange?
The green light indicator means that the power is going to the computer, and not the battery (i.e: when the battery is fully charged). The orange light indicates that the battery is charging. In your case it takes a few seconds to determine that the battery needs to be charged. Hence goes from green to orange light.
Is it bad to keep my MacBook Pro plugged in 24/7? Is it hurting the battery in any way?
It is not the best idea to keep a laptop plugged in all the time based on my experiences, and what I have read, but it's not going to immediately destroy the battery or anything.I recently saw this straight from the horses mouth:For proper maintenance [battery life] of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Apple does not recommend leaving your portable plugged in all the time. An ideal use would be a commuter who uses her notebook on the train, then plugs it in at the office to charge. This keeps the battery juices flowing. If on the other hand, you use a desktop computer at work, and save a notebook for infrequent travel, Apple recommends charging and discharging its battery at least once per monthIf you don’t plan on using your notebook for more than six months, Apple recommends that you store the battery with a 50% charge. If you store a battery when it’s fully discharged, it could fall into a deep discharge state, which renders it incapable of holding any charge. Conversely, if you store it fully charged for an extended period of time, the battery may experience some loss of battery capacity, meaning it will have a shorter life. -http://www.apple.com/batteries/n...also Yahoo recently featured this article:"....batteries are like muscles; they need to be worked out regularly to stay healthy. Ideally, you'd use your laptop unplugged at least once a day, like on a train or bus commute or on the couch in front of the TV. If you're not going to use it, constantly charging your battery is a bad idea..."-http://news.yahoo.com/blogs/upgr...The above articles/links also has a lot more advice on laptop batteries.You can find more information on various sites and forums...Some examples:http://guides.macrumors.com/Lapt...http://www.mac-forums.com/forums...http://forums.macrumors.com/show...
