Leaving a Macbook Pro to load

Hi, I want to know if leaving my Macbook Pro (13 inch, retina end 2015) plugged adapter when it is already fully charged can damage the battery and shorten its life. Is it true that when the battery is fully charged and the Macbook is open, it turns to use alternating current only from the adapter and the battery remains inactive?

the battery will draw when it takes, it is not harmful to keep your laptop plugged in at full load as long as you don't store your mac. Periodically, you can use the laptop without the power adapter but do not allow the computer to fully discharge when using it, if you can help it.

  • How to optimize the battery in my MacBook Pro?

    Hey,.

    I just bought a new MacBook Pro 2015 13 inches and I love it so far! Mainly, I bought it for use at the University since I am a student in Architecture and I was told that the MacBook Pro are great for this.

    Anyway, as I always take careful care of my business, I want to know how to maximize the battery in my MacBook Pro? Is it true that whenever I have my MacBook Pro connected to the charger and it reaches the max (100%), the charger stops charging? Also, should I turn off or put to sleep when I'm not using it?

    I have read online some tips, but I want to just make sure that all of its clear. I have a lot of questions to be honest, but if someone can give a brief explanation I would really appreciate it!

    Thanks in advance.

    Hi Josetroti:

    When you leave your MacBook Pro is plugged, it stops to load automatically when it reaches 100%. There's no need to unplug it.

    I turn on my Macbook Pro in the morning and left running unless I'm going out for a few hours in this case, I if it turned off.

    In the night I turned off it. I don't use mode 'sleep', as with the SSD climbing boots Macbook very quickly. But that's just my preference.

    I heard that if you leave your computer connected permanently, a once a month, you must let sink to about 30% and then recharge.

    It is not good to let it drop below 10%.

  • How can I get Adobe Digital Editions to work on my Macbook Pro?

    ADE worked well on my old Macbook to download books from Overdrive.  Bought nine Macbook Pro, ADE load down, and can not use it.  When it opened, you receive the following message:

    Error message: error getting license. License Server Communication problem.

    > Problem:

    > E_ACT_NOT_READY


    I tried the command + shift + D, and it does not have a window to remove so I can reauthorize.  What can I do else?

    Hi Annie,.

    I would recommend that you manually delete the activation file as it appears that ADE is stuck in a bad state. Please follow these instructions:

    1. In the Finder, locate the 'Go' option in the menu bar and click on "Go to folder" and type the following command in:
    2. ~/Library/application support/Adobe/Digital Editions.
    3. Delete the activation.dat file in the "Digital Editions" folder.
    4. ADE to restart and it should be disabled at this stage. You should be good to reconnect.
  • MacBook Pro will not load iPad Pro

    I have a new iPad Pro.  It seems that my MacBook Pro (retina, mid-2012) is unable to load the iPad Pro.  I see in the iPad Pro (lightning) loading symbol indicating that he is in charge, but the percentage of the battery declines nonetheless.  If I plug the iPad Pro into the power adapter provided with it (or even in a power supply iPad 1) then it costs.

    My MacBook Pro is able to charge iPad Pro?

    Thank you!

    Correct, and it has been so for all iPads.  The output power of the USB port on the computer is not enough to fuel the iPad in use and load it.  Apple has always recommended using the power that comes with the iPad to recharge it as it's output is higher than a standard edge computer USB port

    The smaller models of iPad (and maybe even the Pro, I have not tried) fresh peut leave a port of the computer if left in mode 'sleep' all connected, but even in this case, the charge rate will be much slower than if using the iPad Pro 12W power supply.

  • How low should I leave the battery on my MacBook Pro before I recharge

    I have a new MacBook Pro and I know that once a month I'm supposed to leave the battery discharged.  But how low should it let?

    Don't let the battery discharge to 0. You must load whenever it is convenient. There is no battery memory as the old batteries so you can load any level of discharge.

  • MacBook Pro glued on the filled during boot loading bar

    My MacBook Pro (end of 2011; El Capitan 10.11.5) is recently become insensitive at the point of being unusable, so I decided to do a clean install, since I had to do one for a while anyway. Once I reinstalled El Capitan, I took my SSD (Samsung 840 EVO; 500 GB) out of the enclosure and put it back in my MacBook Pro, but it wouldn't boot. As a first step, it loaded so slowly that I decided to reset the NVRAM, who ends up helping just a little. The loading bar fills now halfway to the top with the usual speed, but after that, it takes a few minutes to complete. And once it is full, nothing happens. He remains on the Apple logo and the bar filled little matter how long wait.

    I also put the 500 GB SSD with the clean install in an another MacBook (Late 2008) and it works fine, so the problem must be related to hardware, I just can't determine what exactly. I tried to do an AHT, but basic and extended trials got stuck shortly after and gave me no result. I had trouble with the kernel panics, so I suspect that something may be wrong with my RAM, as I exchanged the 4 GB to 16 GB just now. But before you go out and spend money on the new RAM, I wanted to know if maybe someone runs into this behavior before and knows exactly what's going on or if not how I understand what is wrong.

    Almost all of the kernel panic seemed to happen every time I was using Photoshop or video in Safari streaming. I'll post an old report of kernel panic, but a problem with Time Machine has led to the removal of all my past, with the exception of the most recent backups. I hope someone can help me find another way to understand what is wrong.

    Update: I just tried it on an other SSD (same model, 250 GB) which has been working well in my older MacBook and this time I get an error message as soon as the loading bar starts to fill to the top. It remains for a few seconds, then the MacBook stops and starts again; This continues in an endless loop. I have attached a picture below.

    I really don't know how exactly to interpret this, but this looks like a kernel panic for me. What is my RAM after all? I appreciate any comment on that.

    Connect the SSD to the external MBP via USB and see if it will start the MBP.  If so, the internal SATA cable is suspect.

    If you can get the MBP to start, then you can start to deal with panics of the kernel:

  • load a MacBook Pro with a 2 85 w MagSafe

    No problem load of a MacBook Pro 13 of retina with a power adapter 85W MagSafe 2?

    If it fits, it works. It will not damage anything, and it cooler. It's just more heavy to wear.

    If your MacBook uses the older MagSafe, MagSafe-2 may not match.

  • Is there a usb2 cable available magsafe2 to load a MacBook Pro?

    Is there a usb2 cable available magsafe2 to load a MacBook Pro w/Retina Display?

    No, and there is not enough power in a USB port no matter what to a MacBook Pro.

    Office supplies USB up to 0.5 Amps of power at 5 Volts. Which allows to load an iPhone.

    The smallest power supply for a 13 "MacBook Pro 15" requires more 3.6 amps to about 16.5 Volts. The 15 "attracts a lot more.

    Bought a new 13 "Macbook Pro. What is the right way to use it? I'm on the computer all day, usually early in the morning and again in the afternoon. The last computer I bought they advised me to just leave all the time and put it to sleep. Now some say to turn it off. What is the right way to get the most life out of my computer? Thank you!

    Have sleep/power nap when not use.

    Once a month drain to 10% battery and then recharge it fully.

  • My Macbook pro stops unexpectedly when approximately 30% of load.

    Hello

    I have a Macbook Pro late 2011 2.8 GHz, 4 GB of Ram (I've already ordered a kit of 8 GB and waiting for her) running on OSX El Capitan and recently changed the battery. It worked fine for the first two weeks. It loads normally and work fine without fresh power. A week ago, he began to stop himself when he was about 30% remaining battery. Indication of battery level lights flashing a couple of times, everything as he had no more battery left and 3 of them would be on again. If I tried to turn it on, it would go up to a certain point and then close itself again. It wouldn't light up to accused. I've read that it could be due to heat problems, but this occurs even when the fans are very low and the macbook is cold. I read this reset THAT SMC can solve the problem that I did that and still nothing. Can someone help me please?

    Thanks in advance.
