Is it better to use my mac with the power cord plugged in?

I'm at 100%  but have heard somewhere that leaving my Macbook pro plugged in while using it is better?  what is best to prolong battery life?

Here are the authoritative Apple support articles regarding their batteries.  If you read the first two on the list, it should answer your query:

  • Is it better to use my Pro with the power adapter plugged in or out?

    After charging my MBP's battery to 100%, which is better?
    - keep the power adapter plugged in to the laptop and resume using until you want to turn off the laptop
    OR
    - because the battery is already at 100%, unplug the adapter and resume using until you feel like you should charge the laptop again (maybe around 80%-90%)

    If you are convenient to an AC outlet it's fine to use the adapter. However, keeping the AC adapter connected will not have an adverse affect on the battery. Once the battery has been fully charged it will stop charging. Recharge will begin once the battery's charge drops below 95%. LIthium-Ion/Polymer batteries do not exhibit memory effects.

  • Using your Mac with the BBC, or not perhaps!

    I just wanted to bring to your attention that the BBC is conducting a survey about the future of online program content and unless we let them know there is a possiblity that Mac users will be excluded from this future service.
    If you want to tell the BBC what you think please follow the link (and click on the questions tab) and fill in the online questionaire: http://www.bbc.co.uk/bbctrust/consult/open-consultations/ondemand_services.html

    This really needs spreading through the Mac
    community- it is important, otherwise the BBC might
    sideline Mac users in favour of Microsoft products!
    Surely it's also important that Apple are pro-active in these matters too ?
    Surely the BBC would appreciate help from Apple in resolving their problem.
    At the moment the have the major share of the music download market. However there are rumblings in Europe - both with the EEC and with individual countries - concerning their DRM mechanism and the fact that it is not available to others, which is aledged to be restrictive.
    If Apple were to license the DRM system to others then it might lose a percentage of it's market share in both sales [as ipod users would be easily able to purchase product from other vendors] and hardware [as some customers might buy other mp3/mpeg4 players] however it would also be able to increase sales buy adding those who already have other hardware systems to it's potential customer base. It would also silence the critics, avoid possible litigation and sanctions and publicize the company further as, even if the DRM licensing was done free or at cost, the sytem would surely need to be credited by the end user for the consumer to see thus raising the company profile further.
    Failure to do this could result in a missed opportunity as corporations [like the BBC] put their business with the majority platform.
    This could potentially be the biggest opportunity for Apple since 1986 and it is vital that they capitalize on it.

  • If I use my I pad with the power source plugged in will it affect the battery ?

    Is it harmful to the battery if I leave the I pad plugged in while in use?

    I do it all the time.
    It does need to be plugged into the wall, not into your USB (Most USB's give out so little power that using actually drains more than is coming into the iPad), but it works just fine plugged in.

  • Has anyone had a problem with the power cord to a Macbook Pro?

    I've had three power cords go bad, Apple claims its mis-use, I've been very careful. Anyone else had this problem? How can I gat a free replacement?

    I have the same problem with my iPad 1. Have you found a fix?

  • Anyone else having trouble with the power cord?

    A few days ago I plugged my iPhone in to charge and nothing happened, I moved the cord a little then it started working. It's happened a few times since then, even in my car (which is a different cord) I've noticed that blowing the end that goes into the iPhone and the area it goes into seems to help.
    I'm not sure about how to handle it, I mean if its multiple cords messing up then wouldn't it be the phone?
    Anyways, let me know what you think.

    ive been having trouble too.
    I have to do it multipletimes before it starts working.

  • MBP random shutdown even with power cord plugged in

    My MacBook Pro (original) has now randomly shut down 5 times since I installed 10.5.6 the week before Christmas. 4 of those 5 times happened with the power cord plugged in, the green indicator light on and the installed battery fully charged. I have two batteries and it has happened with each of them at least twice. Yesterday I got my first shutdown while on battery only. After each shutdown I was able to restart the computer and it operated normally, even the one on battery only.
    These shutdowns are fast and complete. There is no warning of any kind. The screen just goes blank. It is not sleeping, there is no pulsing light on the front. Using the start key begins the process from scratch with the Apple "startup chime."
    The occurrences have gotten more frequent. The first two were within 24 hours of when I installed 10.5.6 and they happened within several hours of each other. Both of these were with the power cord attached and fully charged batteries. I swapped the battery after the first one. When it happened again, I swapped them again.
    The next time I had the problem was 1/30 (last Friday). The only significant software installation I had done between installing 10.5.6 and then was to install iLife '09 on 1/28. All software updates had been installed in a timely manner. Friday the laptop was plugged into external power and the battery was fully charged, but I don't know which battery was installed.
    2/1 I had an issue where my computer couldn't locate the OS file on startup so I did a archive and install. It operated normally since then until yesterday, 2/4 when I had two shutdowns. The first I had the computer on external power and a fully charged battery. The second was the ONLY time I have had the shutdown occur while on battery power only. I was on a flight when the second shutdown occurred. I had used all the power in the battery that was installed when the first shutdown happened (down to about 11 minutes remaining). I then swapped batteries without shutting the computer down. The system rebuilt itself normally and I began working on iPhoto. About an hour later it just shutdown. I was able to restart the computer normally and used it for another 45 minutes or so before I shut it down for landing.
    I called Apple Care this morning and they advised me to get an appointment with a Genius. I resist being without my laptop but will try this and let them look over the console log to see if they can find anything.
    I have done all the basics, reset the PMU, zapped the PRAM and repaired disk permissions. The next thing I am going to do is to calibrate both batteries. I doubt this will have any impact on the issue because most of the shutdowns have occurred with external power connected. I just haven't done this in a while.
    Any ideas out there? Anyone have a similar problem?
    I have another issue on my Mac Pro since installing 10.5.6 and my wife's iMac G5 has a completely different issue since installing 10.5 (I didn't install this OS until last week so I could get the new iLife on it). Seems like this latest OS version is a bit buggy or at least incompatible with a lot of Apple's products in different ways.
    Fight On!

    UPDATE:
    Service was due and now that I saw the machine fail 4 times in a day doing the same process I knew I could duplicate the issue on demand. That's a big bonus.
    Called Apple Care yesterday morning and the guy I spoke with read over the notes on my case after I told him what happened the day before (black friday, 4 shutdowns). While he didn't transfer me to a Product Specialist, he did talk to one for quite a while (I was on hold for about 20 minutes while he did this). He said I could ship it to Apple and they would look at it or I could take it to an Apple Store or Authorized Service Center. Thinking this was the next step I had secured a time at the Carlsbad Apple Store for late that afternoon (my usual & closest store, Escondido, was booked all weekend). They told me to take it in and reference the case number. The Product Specialist thought it sounded like a logic board and would duly note that diagnosis in the case history.
    After the conversation ended I decided to make sure I could cause the failure. So I started the process (threw out the face.db from the iPhoto Library package and opened iPhoto whereupon iPhoto begins a scan of the images for faces. Having over 12,000 images gives it a lot of work). This time I decided to monitor the workings of the laptop using iStat Pro (freeware widget download & I recommend making a small donation it's so good). I kept track of the processes at 5 minute intervals, the CPU usage, numerous temps AND the fan speed. The latter seemed to be the critical. Shortly after the fan speed got to 4700 the shutdown occurred. It took 36 minutes from the time I started. The fans kind of confirm to me that it could be the logic board.
    I took the laptop to the Apple Store and started the process in front of the "Genius." He read through the case as well as the printed copy of this thread and other notes I brought from previous shutdowns including the data I mined from iStat Pro. He was unimpressed and thought it was a non-issue. I guess that's only fair because I was unimpressed with him. He figures it's my system because of a software conflict somewhere. His answer was to do a clean install and reinstall all the software from the original disks. I told him I have spent over 50 hours on this issue to date and that what he was suggesting would take at least that much and guarantee nothing if it's a database issue...duh! Disagreement. Oh, and he also doubted it would fail just from making it work.
    43 minutes after starting the process, well after my "Genius" went home for the day (I was his last appointment), the failure occurred. The "Genius" he handed me off to was working with someone else next to where I was sitting. When the fans hit 4700 rpm I told her it was going to happen soon and as I finished my sentence the failure occurred! Cool.
    They have the machine and I'll let you know what they do.
    Fight On!

  • Hp mini display only comes on with power cord plugged in

    I have a mini 210-3000 that fell on the floor a while back.  After that the display will only come on (the system is completely booted up) with the power supply plugged into the jack.  The cord doesn't need to be plugged into the wall, just plugged into the notebook.  Everything else works perfectly.
    Took to local repair guy and he couldn't figure it out.

    Hi @mikeybr550 ,
    Thank you for visiting the HP Support Forums and Welcome. I have read about your HP Mini 210 and battery issues.
    You could check this document on testing and calibrating the battery using HP Support Assistant. It gives HP Battery Check results with links that could help.
    Have you removed the battery and inspected the connections?
    Please let me know how this goes.
    Thanks.

  • My MacBook Air won't charge using the power cord and it's not the power cord that's malfunctioning. The battery is now exhausted.

    My MacBook Air won't charge using the power cord and it's not the power cord that's malfunctioning. I went to Radio Shack and tried two new cords. The battery is now dead. Any thoughts?

    Unfortunately, my battery has died as a result of not being able to charge with the power cord. Not sure what an SMC reset is but I have made an appointment to bring my laptop in to the Apple Store. Thank you for your response. Very much appreciated.
    Warm Regards,

  • Macbook will not start up with power cord plugged in

    hi,
    my macbook core duo, wont startup anymore with the power cord.
    It does work with a battery though. But the problem is that the cord is not charging the battery anymore and not even giving power to the machine.
    the light on the cord is green. I tried with another power cord, it does the same.
    i even changed the dc-in board, with no luck.
    any ideas ?

    I have the exact same problem. There is a buzz from the region where the power connection is, and I'm afraid it is a power hardware issue. Since the optical drive already quit on this first gen MacBook, I think it's time to chuck this lemon.

  • HP G62 Will Not Boot With Power Cord Plugged In

    I have an HP G62 laptop that is about four years old. I've had a couple of problems with it before that were resolved relatively satisfactorily, however five or six months ago I started having a new issue. The laptop will not boot with the charging cord plugged in, whether there is a battery in it or not. Nor will it return from sleep mode (screen black, status light on the power button flashing) with the charging cord plugged in, whether there is a battery in it or not. It simply shuts down and I end up with an error screen the next time I boot up. I have tried other charging cords and it has been the same, however the cord will still charge the battery. This means I have to charge the battery, unplug the cord, boot up the computer. This annoyance is worsened by the fact that the battery  is old and unable to  hold charge for very long at all and I fear one day even the battery won't be enough to boot the computer.Can I fix the power cord issue? Should I buy a new battery? Or let my computer give up the ghost and scrounge for a new one? Any help would be greatly appreciated.

    the charger input could possibly need replaced and/or the charger

  • Is it possible to use a Mac with an embroidery sewing machine?

    Is it possible to use a Mac with an embroidery sewing machine?

    Computer support for that type of equipment is completely up to the company making/selling the embroidery software, not the computer builder. A Mac likely could support any such device BUT the device makers must choose to include Mac software versions. Many specialty software developers are about 15 yeas in the past and thing no one uses Macs, or they are doing the project on a shoestring budget and would have to hire someone on the outside to port the program to Mac.
    As that function is likely of very narrow interest around here, I think you would do better to visit some of the embroidery sites and see if they mention products with known Mac support.
    Otherwise you will have to find the sites for every embroidery machine maker to look for mention of Mac support.
