Can I keep the power cord plugged in when battery reaches 100%l?

Hello,
I'm assuming the battery stops recharging when it reaches 100%, right? In other words I can keep the power chord plugged in without any risk of "overcharging". Correct?
Thanks.

Helpful, thanks. FYI, 2 Apple agents at Mac support have advised otherwise (said I have to remove the cord).
How bizarre....I have a 2.5 year old MacBook that gets great battery life (~4hrs) and begs to differ. Anyway, Thanks for the Star!

  • HT4060 Can I use the power cord (30-pin and USB) that came with iPad 2 to charge it in my car's USB port?

    Can I use the power cord (30-pin and USB) that came with iPad 2 to charge it in my car's USB port?  Or do I need to purchase one of those cigarette lighter charging devices?  Thanks!

    You'd have to read your car manual but chances are it won't put out enough power for the iPad. The car is likely set up to charge a phone, most of which typically want half the power an iPad wants.
    I think your  options are to get a cigarette lighter looking charger, making sure it's powerful enough for an iPad...or you can get power inverters for about $25, where they plug into the cigarette lighter/power point and have a normal household type outlet on the other end. Then you'd just plug your charger  in like you would at home.
    Another option would be to look for something like a Zagg Sparq, which is a battery operated charger...plug the Sparq into the outlet at home. Its battery holds a charge and you can use that to charge your device. (zagg isn't the only manufacturer of such a device, Targus has one as well). Just look for portable chargers.
    The key to remember is to make sure it's rated for an iPad, which will want more power than a cell phone.

  • Where can you get the power cord for a 2012 airport express?

    Where can you get a power cord for a 2012 airport express or the equivalent? I couldn't find one in the online store.

    I'm sure the OP found his solution, but I wanted to share mine in case it helps some future seeker.
    There are a lot of brand new cords on eBay for less than $10 including shipping, which is way cheaper than the $39 stereo connector kit or an AC adapter from a retailer.  I just bought a used-like-new one for $5.50.
    The cord is made by Volex, part number APC7Q.  The Apple part number is M9573LL/A.  If the seller got it from the stereo adapter kit, they'll probably list it under MD836LL/A, which is the kit's part number.  I got the best search results on eBay using just the Volex part number.
    Best of luck!

  • Can get past the "Power adapter plugging into wall" icon

    I just got my brothers older 60gb Photo ipod and am trying to get it working on my computer. Did the whole restore thing, but now it is stuck at the Power adapter plugging into wall icon. I didn't have the original wall plug so I got a universal one at Radio Shack. Only the ipod still has the darn icon on it and I can't get past it. Any suggestions>

    Lets do a trick. Connect the iPod and the cabel. The USB connector has 2 prongs that stick out a little more than the rest the goal. is to push it in a little so it charges but does not sync. Give It A Try.

  • I have iPad and I touch can I use the power cord

    I have an iPad and an itouch can I use the same power cord

    If you only want to use the one charger for both devices (e.g. to take on holiday) then the iPad's charger would be the best one to use as that will charge the iPad quicker, and it's safe to use with iPods and iPhones (http://support.apple.com/kb/HT4327)

  • Is keeping the your macbook plugged in while battery charged ok?

    Is it harmful to your macbooks overall battery life if you keep it plugged in if the battery is fully charged?

    It is OK to leave your battery hooked to the charger most of the time. The only time I unhook mine from the charger is when I calibrate. You should calibrate your battery once a month. Li-Ion batteries prefer small charges so anytime you want to charge is fine.
    The following links have good information about the MacBook and the care of it's battery.

  • How can I keep the old version of iMovie when I add the new version?

    In the past, when I new version of iMovie came out, I kept the old working version by puttting it inito a folder, and labeled it 'Old iMovie', or some such.  When I installed the new version, it didn't recognize that folder, and left the old version alone. That way, if there were bugs/problems with the new version, I could always revert to the "old" version, without probems.
    Would that still work?
    Thanks
    Hal
    PS:  How is the new version working? 

    You don't need to move anything around. Apple has anticipated that some people may prefer to use the old version along with the new one, so when you update to iMovie 10, a script runs that puts your iMovie 9 into a folder inside your Applications folder:
    /Applications/iMovie 9.0.9
    People are having a lot of problems with the new version. You can look through this forum to find out what they are, and see if there are workarounds.
    I updated to 10, updated all my Projects and Events, and began using it; but after about 10 days decided to go back to 9. I'll try 10 again when Apple releases an update to fix the problems and add back some of the features they stripped out.

  • How can I keep the order of my photos when I synch them with my iPad

    Prior to transferring my photos to my iPad, I arrange the photos in a specific order.  Once the transfer to my iPad is complete, the sequence/ordering of the photos from the Album/Event never stays in tact.  I am using iTunes to manage the transfer process.  Is there a trick to making the photos all transfer in the order they were originally placed? 

    Thanks for the quick response.  Sorry about the lack of info.  I am using iPhoto to compile and arrange my photos.  I am using IOS 8.1.3  on my iPad.  I went as far as to include the sequence number for each photo in hopes it would sort by sequence.  But if it is by capture date etc... then I guess that won't help.  I wasn't aware that you could rearrange the order of your photos once they had transferred to the iPad.  I guess I could also create a slideshow of the photos and synch it with the iPad..  That should maintain the order...  Thanks again..

  • Why can I not play music through my headphones while the power cord is plugged in?

    When my headphones and power cord are plugged in at the same time, audio will not play through the headphones, and the volume bar goes away. Why?

    What is the other end of the power cord plugged in to? If it isn't an Apple wall adapter the phone probably sees it as an audio device.

  • HP ProBook 4530s orange blinking led, won't recognise the power cord

    Hello!
    yestarday I tried to open my laptop but it didn't start. i thought that maybe the battery was empty so i plugged the power cord, but nothing happened.
    then I noticed the led near the power cord blinking orange. After a fast googling i came to this thread ( http://h30434.www3.hp.com/t5/Notebook-Hardware/charging-light-blinking-problem-with-hp-probook-4530s... )
    using the 8-step guide I managed to boot the laptop just to realise that it won't detect the power cord!
    It was really strange, because when I noticed this, my battery was already at 2%!
    I shut down the laptop, and tried to open it without the battery, it booted normally, but it still can't detect that the power cord is plugged in!!!!!
    On the other thread some mentioned to update the bios, but in my case where it can't detect the power cord, that's impossible, because the procedure requires the laptop to be plugged in.
    Now the laptop won't start normally, I have to keep the power button pressed for 40 secs and then plug the power cord. In addition it won't work only with battery, and that is my biggest problem!!
    What should I do now?

  • G4 ibook won't turn on the power cord stays orange and won't charge the bat

    I plugged my g4 ibook in and it turned the computer
    off, I am in Ghana and used a surge protector but
    think this might be the reason. I have tried
    resetting the PMU and the orange indicator light on
    the power cord blinks green when I do this but then
    nothing happens. The battery on the bottom only one
    light lights up when pushing the battery button. Has
    anyone else had this problem.
    In addition I removed the battery and the power indicator light went to green without the battery in and the power in it, but absolutely nothing. Replaced the battery and nothing. Please help I am in Ghana, and have no way to get help!!!

    Hey Ryan,
    Can you hear drumming [I studied with a Ghanian master from the Univ. there for 5 years and have a few hand carved djembes which are awesome].
    I'm hoping that will divert you because you're not likely to find a new adapter there but that's undoubtedly the problem. I bent the prong on one slightly and it did the same thing, it's possible yours is like that. If you don't have any knowledge of it being bent it probably happened inadvertently, so you might try letting it sit out in the hot African sun until the gold is very malable then just run your fingers round the prong very lightly try to align it. I tried all night and this didn't work but it did get the thing closer so it might work for you.
    Here's a link to a very good price where I got my replacement and it's good $38: http://store.shentech.com/ap24v145wsqs.html

  • 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

  • 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!
