MacBook Pro :: Fully Charged But Still Does Not Turn On Without Charger

Sep 10, 2014

I 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.

Mar 5, 2010

So I charged my battery to 100% and then unplugged it from the charger. Thats when the battery dipped to 97% instantaneously. It was very odd and somewhat scary. I just bought this MBP 2 days ago! Anything i might be missing? Is it supposed to do that?

MacBook :: Plugged In Long Past The Fully Charged Time Good For Battery?

Dec 9, 2009

i'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?

Hardware :: New MBP Battery At 95% Fully Charged?

Dec 22, 2010

I 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.

Sep 28, 2008

Is it better to keep the charger in after a completely charged or pull out the charger. Basically I'm wondering if the power is pulled from the UPS after the battery is completely charged or is it still constantly charging the battery.

MacBook Pro :: MBP Says It's Charged - But Not Fully?

Feb 22, 2010

Basically. 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, 2010

I 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..

Hardware :: Apple Battery Charger Or 3rd Party Battery Charger Bettter For The System

Aug 11, 2010

The Apple one looks tempting as it comes with 6 batteries and 29€ isn't too much, plus, as usual, it looks brilliant. I looked at some 3rd party chargers as well ranging from 20€ to 40€. None of them was stunning or special by any means. Cheaper ones usually came with two or four batteries and some came without batteries. I don't really need it for else than Magic Mouse, occasionally for something else too.

Hardware :: New Apple Batteries Only At 74% When Fully Charged?

Oct 4, 2010

I 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?
