I use my MBP 15" (the new one), as my primary machine in my office. I sit by my best usually 10-12hrs a day working on it.
I am trying to figure out what is best to do, keep the AC plugged in or have it un-plugged and only plug it in when the battery is drained (or less then 50%)? I have tried different experiments, plugged in, not-plugged and time is about the same for life of the battery. The true question is, how is is best to do it for the health of the battery.
I just bought the new MBP 13" 'cause I'm gonna need it for college, but since I'll also use it as "personal computer", for web browsing, playing music and movies, I'll probably have to charge every day. My question is: if I got home and my MBP is dead, I plug it in and use it, when the battery is fully charged, I have to unplug it or I can use it for the night (still plugged in) and just unplug it the next day for school?
Is it somehow harmful to my battery life? And by the way, I've read that "discharge the battery" means just use at least until the 50%, is that right? So if I charge it just when it's about 40%, I just need to recalibrate once a month, and that's all fine, right?
My wife and I always leave our MBP plugged up when we are near a charger. This morning the MBP had been plugged up all night, but the battery was dead. I noticed the light was out on the charger so I went to take it out, but when I touched it it turned red indicating that it was now charging. It turns out it is very finicky and randomly stops charging. Anybody else had problems with their charger? It will be Thursday before I have a chance to get to the Apple store.
I bought my MacBook Pro 13.3" 5 months ago (according to Coconut Battery) and the battery-loadcycle is already at 51 and 89% battery capacity. Anyway I wanted to know, if I keep my Mac plugged in on the charger will the battery-loadcycles decrease?
I bought my macbook exactly two weeks ago (tomorrow) and I'm already starting to have problems. My battery is currently at 10% when not plugged in but then when I plug it in it won't charge. What is wrong with it?
i very rarely use my MacBookPro away from home (scared of loosing it, LOL) almost all the time it is plugged into the mains 24/7, i just shut the lid when i am not using it. It is about 12 months old, but i notice that the battery meter never goes above 96%, does this mean the battery is on the way out and is going to get progressively worse ?I suppose it means the battery isnt going to last anywhere near 6 or 7 hours if i did unplug it from the mains?
Info: MacBook Pro, Mac OS X (10.7.2), iPad 2, iPhone 4S
my macbook will not start unless its plugged in to a power source. if you unplug it while running, instead of switching to battery power, it shuts off. the battery is currently at 53%, so i do not know why it will not run on the battery.
I just noticed that my when I got my macbook plugged in, it's not charging. The icon is the one you got when it's plugged in (with the little fork-shaped thing in the middle), but instead of it saying 'charging' like when the battery isn't full, or 'charged', when it is, it just says 'Not Charging'. It's like it can see the magsafe connector inside, but the juice isn't coming through to the battery, even though the computer itself is powered by the charger since when I click on the power symbol I get 'Power source: Power adapter'.
Also, the magsafe connector itself isn't lit. It used to be green for a bit, but a much weaker green than normal, and before that it wasn't even lit--I've tried with three different wall outlets, one of which was outside my house where I usually use it (it was in a starbucks). Also, when I disconnected the magsafe to get a reading for the battery, it was only 1:35, even though the magsafe light was green (albeit a weak green). If it matters, I'm running 10.5.3. The macbook is still fairly new, bought mid-december, all updates current as I got it set to checking daily and install the minute I get the notice.
I have a brand new MacBook ( < 1 month old ). I usually leave it plugged in and sleeping on my desk, and open it up to use it. After about a day of this, it will still say the battery is fully charged, and the light on the MagSafe is green, but the batter display shows 99% (or 98%, 97%, 96%). If I unplug it and use it for a bit, and the plug it in again, the battery will charge back up to 100% (and then the whole process will begin again). I love my MacBook, and want to make sure this behavior is normal.
About a month ago I bought one of the new Macbook Pros, a 15 inch i7 version with highres matte screen.This morning I went to turn on my computer and I thought I had turned it off last night, but it turns out that I hadn't, so when I hit the start button it woke up and then promptly shut off. I haven't been able to get it to turn on since. Absolutely nothing happens when I push the start button, whether I have it plugged into battery power or not.
So 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.
This morning I set to work on my laptop as usual. I typically leave it plugged in while not moving around, and today was no exception. I h ave a 15" macbook I purchased in December of 2010, and it's currently running OS X 10.6.8, if that makes a difference.
Anyhow, when I started up my Macbook and set to work, the battery was fully charged (indicator read that it was fully charge, and that the power source was the power adapter). The power adapter light was green. I then stood up and did some work for roughly 2 hours away from the laptop. When Ieft, I put the display to sleep - In the background the machine was still running a webbrowser (reading an all-text page) and preview (a PDF was open). This is nothing out of the oridinary, and I do it all the time usually.
What was unusual was when I returned to my machine after 2 hours of idling (with the display asleep) to find that my battery had been almost completely drained. The power adapter light was now orange, and the indicator showed that the battery was only 4% charged. The power source was still displayed as the power adapter.
I understand that during intense processses the Macbook will draw from the battery AND the power adapter - But my Macbook was simply idling! I can't fathom that a webbrowser and Preview would require THAT much draw for power. In fact, I've run my Macbook MUCH more intensely for much longer periods of time when running Final Cut and Adobe After Effects and NEVER seen this issue before.
Is this an indication of a failing battery? Ever since I noticed this, the charging time indicated has held steady at ~1:13 (that's been about a half an hour now). I don't know if the Macbook will discharge the battery completely every so often by itself, or if the battery is just failing and that's why it went from 100% to 4% in just under two hours while idle.
I have a late Macbook Pro 13''I using it at home about 10 hours a day. so it's allways plugged in to AC Power while I'm using it, and when I'm not using, I disconect it from Power.I want to know if this damage my battery OR not? Or should I running my Macbook on Battery? and recharge it (and cycle monthly ... )
I play a game called League of Legends which is fairly computer intensive. While playing, my battery continues to discharge continuously even though I have it plugged into the wall. I can usually get 3-4 games in before I have to stop and let the battery recharge. I have already decreased the screen brightness to half, turned off the keyboard back-light, and made sure that bluetooth was off yet the issue persists. I have noticed that the light on the charger seems to change colors often. It will cycle from green to orange to off then back to green again etc.
I have an early 2012 15" Macbook Pro with the latest version of Mavericks OS.
Problem: Once shut off, my Macbook pro won't turn on by pressing the power button. It is as if I must jump start the computer using the power cord. What is interesting is that if I push the power button (without the power cord plugged in) the macbook won't turn on, then, when I plug the power cord in, the computer magically turns on without my PRESSING the power button. It is as if the computer knows it has been told to turn on but is waiting for more electricity.
When the computer is on, The power button also doesn't react when I press it. As recall, on macs, pressing the power button quickly creates a pop up menu that asks if:
a. you want to shut down the computer b. restart the computer c. put the computer to sleep
This computer will shut off if I hold the power button down but does not give me the pop up options.
Battery appears to be in good health. Though it has been through 780 cycles. Coconut battery says that the battery is fine. This Macbook Pro's Sd slot stopped working as well.
just curious, does anyone else's MBP's battery slowly lose charge over time even though it's plugged in? I've got a 2010 MBP 13". Mine only is ever at 100% right after I have used the battery and just recharged it. then it will slowly lose that charge over time until I unplug it, use the battery enough for it to actually charge the battery when I plug it in. (Oh, and coconut battery has never said it ever had 100% full original battery capacity, best it ever said was 97%).
I had some issues with battery drain while sleeping awhile ago but that problem has been solved. However, ever since that incident I could not be paranoid about the battery life etc.I heard people saying that leaving the charger plugged in is simply fine as long as I do the regular calibration once or twice a month or so. Yet, Apple stated that they do not recommend the laptops to be plugged in. I will be going to a college this Sept and I really do want my laptop to last at least the whole 4 years.
Ever since I have contacted Apple customer service about this Battery issue I have left my Macbook charged up and plugged in while using and letting it sleep. One thing I have noticed is that the battery indicator says 99% and doesn't increase or decrease yet the green light is on. Is that normal? Since this is my first Mac ever and also first Laptop I would like some advice on how to treat the Battery( I know how to do Calibration and such). Is it better to do full cycle usage of Alum Macbook battery than leaving it plugged in all the time? (I unplug it when the Macbook is off).
my laptop is less than a month old, but i've noticed when it's plugged in (i don't run on battery power), the battery percentage is going down. not the capacity, but just how much charge the laptop has. (excuse me if i'm using the wrong terms). and in about one-two weeks, the battery goes down past 95% and it starts charging itself.
While unhooking my battery, I accidentally touched the metal contacts near the battery cable connector on my mid 2009 with a screw driver. My computer says 'battery not found' and only turns on while plugged in. The computer doesn't detect a battery in the system profiler. Will buying a new battery resolve my issue?
I let my new mbp(mid 2012) battery run down. It was on, I walked away for one minute and came back and the mbp was shut down. I plugged in charger and the mbp won't turn on at all. I got it on Tuesday so it is brand new.
My magsafe 2 is plugged in but the light's not on. My battery status shows it plugged in, but says "battery is not charging."
I've reset the SMC several times and have been able to get it to work again, sometimes after going through the process several times. Sometimes the yellow light stays on even after I unplug the magsafe.
I bought this MacBook Pro 13 inch, Intel Core i5 in June 2011 and it is Early 2011 model and today I am charging my battery and it plugged in and it wont charge. I have had it where the screen goes black and the plug wont show a light and it wont charge. The condition of the battery is Replace Soon. I dont know what it is.
