MacBook :: Plugged In Long Past The Fully Charged Time Good For Battery?
Dec 9, 2009i've had my macbook for a little under a year and i think i may have shortened my battery power. i have a tendency to leave my laptop plugged in long past the fully charged time and allow it to run through the battery till it shuts down. i do this when i accidentally fall asleep listening to music or leave for work and forget it's on or plugged in. how hard on the battery or laptop is it to do this repeatedly? when it's fully charged it tells me i have roughly 4 hours of battery power available. is that the right amount? is there anything i should do to protect the battery? the manufacturer warranty will be up in march, should i take it in for a check up while i may have the option of not having to pay for it?

Feb 22, 2010Basically. I have my 15" saying that it is charged with the MagSafe light green. Although, the battery percentage is 96%. Ehh.. Is it supposed to be like that?
Like, not charge if it has only a little bit left to charge? Or is something wrong with my battery or MagSafe?
MacBook Pro :: Should I Unplug When Fully Charged?
Oct 19, 2010I have the impression that my MBP still charges when the power lead is hooked into my macbook. Is that true? Do i have to unplug the power cord each time my macbook is charged? Is there any way that the battery life might be affected?
I hope there is some sort of a circuit involved, that stops charging the battery when the battery is full, rather than overcharging it..

MacBook Pro :: It Won't Turn On, Fully Charged?
May 24, 2012I bought a MacBook pro in march 2011 and has been working perfectly fine since then. The charger did break but I purchased a new one. I was using it for most of the day on Tuesday and it worked fine, I shut it down like normal and stored it in it's case overnight. On Wednesday morning I tried to switch it on and nothing happened! It's fully charged and I've tried the smc reset and nothing happens. There's no fan sounds or anything!

MacBook Pro :: Keeping Battery Charged And Calibrated To Maintain Health
Dec 1, 2009Ever since owning the uMBP, I have kept the battery charged and monthly calibrate it to maintain a 100% battery health. But through this, the laptop limits its portability and it is sometimes extremely tedious to find a plug in order to use it. My question is: Is it really worth it to keep a good battery that will last overtime, or would you prefer simply purchasing a new battery when your old one dies? Also, how big of a difference does a healthy battery compare to a battery put through regular use?

MacBook Pro :: Fully Charged But Still Does Not Turn On Without Charger
Sep 10, 2014I am using Mac Pro with retina display
Processor : 2.5 GHz Intel Core i5
Memory: 4 GB 1600 MHz DDR3
Problem: My mac turns on only when connected to the charger even though it is 100% charged. Once it is on, I can disconnect the charger and continue to work on it.
However, if I don't connect the charger at the initial stage it does not turn on at all.

MacBook Pro :: Can The AC Adaptor For Extended Periods While The Battery Is Fully Charged
Sep 17, 2010"Does it harm the battery or reduce battery life, to use the AC adaptor for extended periods while the battery is fully charged?"Someone answered, "I would have to disagree with the others who say that it hurts your battery & reduces battery life by keeping your AC adapter plugged in with a full battery.I have done extensive research and asked many apple employees and have always come to the same conclusion. They all say to keep your laptop plugged into an power supply whenever possible. Only use your battery if you have to, in those times when you are not near a power supply.

View 3 Replies View RelatedHardware :: New MBP Battery At 95% Fully Charged?
Dec 22, 2010I have a new 13" MBP (1 week old), and the battery is supposed to be fully charged, according to the battery menu and some hardware monitor app. Well, the same menu says the battery is 95% charged, while the MBP is hooked to the home's sector. What the heck is that ? Last week, the information was consistent (100% recharged).
What is happening here ? Is the battery defective or is this normal ? I'm new to the laptop world, so I need to understand what is happening with the battery.
Hardware :: New Apple Batteries Only At 74% When Fully Charged?
Oct 4, 2010I picked up a pair of the apple batteries/charger for use with my magic mouse and wireless keyboard. I still had some juice in my current batteries so charged each set of two batteries for 24 hours and then put them in a drawer. Fast forward two weeks and my magic mouse has reliably run out of juice and when I put in two of the batteries, my mac states the charge at 74%. I've read in some of the other posts that because of the way NiMH and alkaline batteries differ, it is normal to have slightly lower ratings, but 74%?????
Most people reporting stated they got 85%, has anyone else gotten 74% on first run?
Are these batteries defective or is there something about my charging routine that caused them to be so much lower?

MacBook Pro :: Battery Fully Discharging While Plugged In
Jun 15, 2010So today I was using my MBP that I got about a week ago and all of a sudden I got a low battery message. My MBP was plugged in at the time, and had been plugged in for about the last two days. AC adapter was plugged in and very hot i might add. MagSafe never got disconnected. After I clicked ok on the low battery message my MBP just started charging like I'd been using it on battery power and just plugged it in. I know there was no power outage or anything like that, all my computer stuff is plugged in to a UPS that beeps if it looses power and switches to the UPS battery power. I shut my MBP down when I went to work and when I came back it took a good min before it made the powering on noise and the apple appeared. I checked my battery health and capacity through the system profiler and the condition is normal and it has 7 cycles on it.
