Ac plugs vs ac power cord

For macboor pro 15 inch (latest 2013), I can use ac plug to charge but can't use ac power cord to change, does anyone know the problem ?
Thanks.

You should be able to use either connected to the AC transformer to charge your Mac notebook. If the cord isn't working, and you have connected it correctly and seated it all the way onto the transformer section, then you have a problem, faulty, cord. You should take your Mac, the AC charger and both wall socket parts to an Apple store to be checked out and replaced.

  • I have a Mac G4 double mirrored model and everytime I shut it off it will not go on when I hit the power off button. However, if I unplug and plug in the power cord it boots fine and everything is OK. The PMU and logic board have been reset. Any ideas?

    I have a Power Mac G4 double mirrored model and everytime I shut it off it will not go on when I hit the power on/off button again. However, if I unplug and plug in the power cord it boots fine and everything is OK. The PMU and logic board have been reset. Sometimes my Mac goes on just by pressing the power on button but most times I have to pull the power cord and put it back in. Any ideas or help out there for this? Could it be a failing power supply? Apple Care says that this model is obsolete so there is no help from there. John

    Hi John,
    That's often a sign of a bsad Capacitor in the Power Supply, but...
    Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & can cause strange startup problems...

  • My sister gave me her 1st gen iPad to see if I could solve an issue.  It won't turn on, and when it's plugged into a power cord there is a slow pulsing sort of flash that happens on the screen....any ideas?

    Try a Reset [Hold the Home and Sleep/Wake buttons down together for 10 seconds or so (until the Apple logo appears) and then release. When the screen goes blank power On again in the normal way.] It is absolutely/appsolutely safe! Now see if it charges normally and after a period try to turn it on again. If the batter has been drained it could take 20 minutes or so for it to show that it is charging.
    Also considering if the battery need replacing!

  • HT4060 Where on the iPad mini do I plug in the power cord?

    I just bought a new iPad mini and need to recharge the battery.  But I don't see where on the iPad to plug in the power cord.  The power cord has the same male connector as my iPhone 4.  Help!

    Use the cable that came with the iPad mini, not with your iPhone. Different connectors.

  • When I first plug in my power cord it lights up green and then after a few seconds changes to red.  What does this mean and how do I fix it?

    Apple systems in MBP have self-maintaining charging systems.  If the battery is less than 95%, the charger light turns orange when plugged it.  It will charge to 100% and stay green then will hold on charging until the battery drops to 95% again.

  • Have a G3 pismo, works great, but when I plug in the power cord, the light won't come on to indicate its charging. It is charging, and the battery is good, its just that the light won't come on. Could it be something with the backup battery?

    I have a G3 bronze keyboard that works, with a good battery, but when the power supply is plugged in, the charging light on the back of the laptop
    will not come on. It is charging however, and have two different apple power adapters and both will charge the main battery, it's just that the light won't come on.
    Did a reset of the pmu, but no changes. The date stays current, but wondering if the backup battery could be getting weak and affecting it , or is something else going on?

    The power connector in the G3 PowerBook is a weak link.  Removed, it looks like this:
    [image from http://microdocusa.com/specials.html ]
    The connector probably hasn't failed, but the solder joints where "legs" on  the connector  attached to the logic/power board are under a lot of stress after 10 years of use. Little bumps and tugs on the power cord eventually degrade the connection. You can check for looseness easily---see if the connector feels loose when you GENTLY wiggle it with a fingertip. It should have zero play if it's still firmly attached. You can also plug in the power adaptor and see if slight movements if the plug make the light turn on. Pretty diagnostic of a loose connector.
    The date stays current,
    Make sure you are doing this check correctly. If you have an always-on internet connection, the date/time are fed froma  network time server and will always read properly unless you test with the internet connect turned off or disconnected.

  • Will not turn on unless plugged in to power cord

    So I have had my Macbook Pro for about 9 months now. Just today, I unplugged my laptop and it immediately turned off. I tried turning it on; I could hear the optical drive spinning up for a moment, and then the computer would suddenly turn off again.
    The battery appears to be fine (I checked the charge indicator on the bottom, and it is fully charged), and my power cord seems to be ok as well.
    Any help?

    My MacBook Pro is just 4 months old and suddenly it would not operate without power adapter attached. Reset PMU and PRAM to no avail. Repaired permissions and did an fsck in single user mode, again to no avail. Even tried booting in 10.4.10 on external drive which was fine, except laptop would still not work with out being plugged in.
    Called Apple. They asked if I had a colleague with a 15" MacBook Pro from whom I might "borrow" their battery from. Luckily, I did! I replaced my battery with hers and bingo! Laptop worked without using power adapter.
    Apple is sending new replacement battery.
    Another co-worker had the same thing happen to his MacBook Pro this afternoon and his laptop and mine were purchased in the same week.
    Wonder if there is another batch of defective batteries springing up.

  • I just buy a Macbook pro, I have one question that when I use it at home, it is better to plug in AC power cord, or just use teh inernal battery withour AC power?

    I just buy a Macbook pro as a new MAC user. I conceren about internal battery life much. So I have one question that for battery life concern, it is better to use Macbook without AC poower in? or using AC power is better?
    Thanks, welcome anyone who can give me good sugegstion.

  • Kernel At 600% when plugged Into the power cord.

    Everytime my computer is at 0-9% and I plug it in to charge, my computer lags and today I contacted apple support and they told me to check my cpu usage, to my surprise the kernel was at 600% and when I unplugged my computer it went down to 2%. Why is this happening? I have ressted the SMC and PRAM, and it's still the safe. I went into safe mode but it didn't help. What can I do to fix this. I'd also like to add that somethimes my fans get really loud but the SMC reset didn't fix it.
    As of right now my temperature is 144 degrees and my fans are loud. (Is this normal?)

    Make a Genius appointment they will diagnose it for FREE. If you have Apple Care any charges would be covered.

  • Power cord on iPad has 10w adaptor but on iPhone no adaptor on plug. Are they interchangeable?

    Are power cords in UK/IRL on iPad and iPhone interchangeable?
    My iPad has a 10w adaptor on the plug of the power cord and the iPhone power cord has no adaptor. Do I have to carry both power cords when travelling or will one safely charge both devices?
    Also I have a usb charger in my car - can I charge both devices on it?

    The cord itself is interchangable. The power bricks are different. The ipad wants 10W, the iPhone 5W, however you can safely use an iPad charger to charge your iPhone.

  • 6555 Power cord plug problems

    When I plug in the power cord it does not make a solid connection. The only way I can get it to work is by canting the cord, by wrapping the cord around the phone or by taping the phone down and pulling the cord to the side.
    Is this a systematic problem? Am I the only one? If not has anyone found a solution?

    your better of getting new charger this seems to be an issue with the new smaller pins on the charger or it could be an issue with the jack in the phone try a new charger first

  • Satellite Pro U400 sometimes freezes when the power cord is plugged in

    Hello! I know this problem has been discussed here and there but I would like to open a new thread on that. Here is the scenario.
    I have recently bought a new Toshiba Satellite Pro U400-247 (PSU45E) with two batteries: (a) the original one, (b) additionally purchased Toshiba genuine PA3636U-1BRL, 7200 mAh. The notebook has the latest BIOS (4.80) and the latest drivers downloaded from Toshiba and installed (ConfigFree is not installed). I am using XP Pro SP3 (clean install done by myself). Everything is working very well, except for one thing:
    Sometimes (but not always), when the notebook is working on battery and I plug in the power cord, everything freezes and I have to restart. Some observations:
    (a) it tends to happen more frequently when the low battery alarm has already sounded;
    (b) it seems to happen more frequently with the 7200 mAh battery and less frequently with the original battery;
    (c) it seems to happen more often when a USB device (e.g. mouse) has been connected with the notebook, but that is not a rule;
    (d) it seems to happen less frequently when I move the USB mouse at the time I am plugging in the power cord;
    (e) I have experimented a lot with Toshiba PowerSaver's settings (e.g. changed the CPU levels for my profiles) but nothing I have modified seems to change the situation;
    (f) I have tried various suggestions I found on different forums, but no avail (e.g. BIOS settings);
    (g) otherwise, I can say that I really have not seen a smoother computer, everything else is really working just fine, no other problems whatsoever :)
    All this makes me think that this must be some kind of bug in the motherboard drivers, the PowerSaver driver or other drivers interacting with the battery, the CPU or possibly USB. Is there an explanation for this problem and can it be rectified somehow (e.g. by providing a driver update)?

    Hello, thanks for the reply!
    My bad, of course I meant the chipset driver. That, however, does not change the essence of the question. Also, I know that a notebook should function properly even the AC adaptor is connected or not connected. That is why I posted my question.
    As for the OS reinstall, sorry, I would not do that just on some wild guess from somebody. I recently finished the clean OS install. I have installed XP on dozens of notebooks in my life and I know what I am doing. I have been into computers and networking for 15 years and I know when I see a problem not related to how I install my OSes.
    My personal opinion: this problem has not to do with the OS install since the same problem also existed when I test-installed the XP OS image from Toshiba's own downgrade CD (that was before I did a clean install from my own slipstreamed CD). And, if you really use a properly and carefully configured OS with all the necessary software, an OS reinstall is not something you just do every day.
    As for the rest (testing the memory / adapter / motherboard etc.): as I have mentioned, similar (although not identical) topics have been raised in various other instances (e.g. at http://laptopforums.toshiba.com/t5/B...EABCA64EE6C5D9) . That means that this problem is most probably not specific to my computer or even to U400 but it may happen with other Toshiba notebooks too. Therefore a (rather standard) suggestion to spend days on reinstalling (and in my case, carefully reconfiguring) the OS, checking the memory, adapter, mobo etc. does not sound as the most plausible one in this case. FYI, I always do full tests on hardware right after I have installed an OS. In this computer, all tests (Toshiba's own; 3rd party memory diagnostics, HDD diagnostics) were passed OK. Indeed, I did not have the AC adapter tested but as it otherwise works fine, the possible problem (if there is one) would be a minor one to notice, and would require testing at a Toshiba service centre (there is no direct Toshiba agency in my country). I think testing the AC adapter is the last resort as much more probably, the problem lies somewhere else.
    Even if this problem is hardware-related, I do not expect Toshiba to replace all such hardware out there. However, on many occasions, hardware-related problems can be cured or alleviated on the software side (e.g. by a driver or BIOS update). Since it seems that other people are having similar problems with Toshiba hardware/software, I thought that maybe someone has found an actual solution or maybe there are Toshiba employees reading these forums who could look into it.

  • Odd problem using mini display cord and power cord at the same time

    When i connect my mbp to a monitor/tv while running on ac the macbook freezes totally. As soon as i plug in the power cord while running an external monitor the cpu usage goes crazy. Kernal task reporting 100.1 % cpu usage and also high cpu usage (powered, syslogd and configd). The only way to unfreeze the macbook is to unplug the power cord. When i do this the laptop runs perfectly fine again while connected to my monitor.
    The odd thing is that it was running totally fine a few hours ago. but after waking up my mac its showing this issue.
    Would love to get feedback.
    Thanks

    I use a KVM switch with a Dell monitor that has DVI and VGA inputs. I only route the K an M portions (keyboard and mouse) through the switch. The computers connect directly via VGA and DVI to the Monitor, and then I use the monitor's switch to make the video switch. Works fine. Don't worry about taxing the monitor.
    I'd suggest buying the KVM switch from a vendor with easy return policies, since it can take a few tries to find a model you like.

  • IBook screen goes black after unplugging power cord

    I originally posted this topic in the wrong discussion group for iMac G4, the computer is actually an iBook G4.
    My wife's iBook bought about 2 years ago shows battery 100 percent charged. But when she unplugs the power cord the screen goes black. Can not be restarted until she plugs in the power cord. It seems like it might be the battery. She got extra batteries when she bought it. Is there a way to tell if it is the battery before having to replace it?

    Did you check on the status of your battery using "About this Mac" under the Apple on the menu bar? Click on "More Info..." and select Power under Hardware. It will tell you capacity and cycle count.
    You may have a dead battery.

  • Dark screen using power cord after Tiger 10.4.3 update

    My update from 10.3.9 to 10.4.3 on a Powerbook G4 went fine until I realized that plugging in the power cord caused the screen to go dark. I can get it to come back on by shutting it and opening again, but it stays on for only one minute (exactly). Only other way it works is when the battery is charged and I can unplug the power cord.
    I have run Repair Permissions a couple of times, and restarted, to no avail.
    Anyone have a simple answer to this one?
    Thanks.

    See there are separate Energy Saver settings for with power cord and without in Apple menu -> System Preferences -> Energy Saver. If indeed the Energy Saver is set to put the display to sleep after one minute while the power cord is plugged in, that would explain your behavior.
    If that is not what the settings are set for, then I suggest trying to reset the power manager as this article describes:
