Did I damage my battery by using a bad charger?

I plugged in my friends macbook pro charger to charge my MBA at his house like I have done many times before but this time around I did not know that the charger was faulty but by the time he told me it was too late. The charger is having a problem where you need to wiggle it to get it to charge the laptop but it has no visible damage on the outside. It also behaved weirdly after I plugged it into my laptop (which by the way acted normally and started charging with this malfunctioning charger) ; the LED light on the magsafe stayed on after I unplugged it from my laptop but was a dim green as if there was a short inside the plug that was making it think it was still on. I fully charged my battery at home and everything is fine just worried if I had done damage to my laptop and if there are any procedures to check if it is damaged.

Most of your computer's relevant battery condition parameters can be found in the System Profiler located in the Utilities folder of your Applications folder. You did not specify what version of the OS you have. The newer OS, (ie Mountain Lion) will call it "System Information". Open the App, look on the left side and click on "power". There you will find cuurent health, cycle counts, etc. You can also find some apps in the app store that you can download for free that will give you even more info than you need.
Hope this helps,
Paul

  • Ios 7 battery drain - using faster than charging now

    Anyone else have issues getting a full charge on iPhone 4S after updating to ios 7.0?
    It's draining noticable faster - battery drains faster than it charges now so that unless you turn off the screen you end up with less charge than when you docked it. Same goes for regular 30 pin cable to 1Amp wall charger without the dock.
    I left mine over night on the iPhone dock and it still only reached 92%
    Never had issues on ios 6.
    Even with the screen dimmed back to 50% (like I had it set for ios 6),
    Battery was at 45% before updated yesterday and even though it was docked and charging during update was at 36% after the update, and kept dropping the longer I had it connected.
    Does anyone know for sure if ios 7 is using the A5 cpu differently? maybe running it faster or using more power than on ios 6?
    Rebooted my iPhone 4S a few times after updating, nosame issue. Was able to use Safari but unable to download from itunes or app store. They asked or my password, but it said "could not connect to app store, please try again". perhaps due to so many users updating yesterday
    Then after opening a few apps (ebay, amazon) battery meter jumped to 100%
    I do have DND enabled for notice center. update retained that preference and my screen lock code.
    I noticed that even though screen lock timeout was set for 2 mins, it was prompting for code immediately. Had to change to 5 mins, since the 2 minute to lock option has been removed in ios 7.
    Thanks,
    JJ

  • Can I damage my IP by using an iPad charger

    My IP5 is dead today. I have an appointment tomorrow at the Apple store.  I'm wondering if I might have damaged the phone by charging it occasionally with my iPad charger which puts out more juice than the small block charger that came with the IP.

    Notice what Apple says the iPad charger is compatible with.

  • HT201441 hi just bought an iPhone 5s from a guy, did not have any battery , i got home i charged the phone and it had a code restored the phone and now the phone shows lost and erased! what should i do? I'm in ireland and the phone is verizon

    hi just bought an iphone 5s from a guy at the market ! the phone was dead got home charged it and had a lock gone back the guy was gone!i restored the phone and got phone was lost and erased and no other detailes what else can i do the guy said its his phone and its on verizon now but its neverlocked! how can i get this back and working?

    You can't get the phone working without the correct password, because the previous owner activated Find My iPhone and Activation Lock. In order to unlock the phone you would have to ocntact the previos owner of the phone. Unfortunately, this is the only way to get it working again.

  • Can my charger, which originally shipped with my iPod A1040 be used with any of the following models without damaging the battery?

    I know this is a complicated question, but any detailed explanation as to why or how I appreciate it as I have tested and it does actually charge the 1136, 1051 and 1236, but I have been reluctant to try it on the A1288.
    Question:
    Can my charger, which originally shipped for the iPod A1040 be used with any of the following without shortening the battery life or damaging it?
    iPod A1136 (tested, does charge)
    iPod A1051 (tested, does charge)
    iPod A1236 (tested, does charge)
    iPod A1288
    Thanks,

    Is it not charging at all? Did you try to reset? If YES to both, request for a replacement of the ipod. Battery or the unit itself is defective. Cheers!

  • Does keeping a macbook pro plugged in even when fully charged damage the battery in any way?

    Does keeping a macbook pro plugged in even when fully charged damage the battery?

    no it will not, your battery stops charging when it reaches 100%.  you can verify this if you'd like to through system report - power.
    once in a while however, it's best to use it under it's own power and charge it back up once it's down to 75% to keep the battery in optimal condition.

  • Satellite A500-1GL: Is it advisable to remove battery when using mains

    I know this is a silly question but its actually something i don't know so thought i would ask.
    I nearly always plug my notebook into the mains power supply (Sat a500 1gl)
    Just wondering do you actually have to keep the battery installed even when using mains.
    Or is it actually advisable to remove the battery when using mains?
    I did not know if the battery should always be in place.
    Thanks for your help
    torti

    I use notebooks for 10 years now and i have changed several of them. To be clear I use it daily for my business and it is always connected to the mains but I have never removed the battery.
    At the moment I use 3 years old Satellite P200. Battery was never removed but if I try to use it on battery power supply I can work almost two hours without problems. Satellite A500 is one of the newest notebook models with battery of the latest generation so it is not so sensitive as old one and I don't think you must remove it all the time. What you can is to use it from time to time on battery only to make it empty and make full load again.
    Many people here have different opinion and at least it is your decision what to do.

  • Still Having Problem with Battery Overheating with Car Dock/Charger when using Maps/Navigation

    I'm having a problem with the battery overheating when using Google Navigation in the OEM Samsung car dock and car charger.  On a trip last weekend, I started off with a fully charged battery (because posts on other sites have complained that the Charge cannot keep up with the power draw of the Google nav app while using the car charger).  About an hour into my trip, I got a message that the battery was overheating and to unplug the charger which I did.  I then had to contend with the screen going out because it was running on the battery.  I let the phone discharge to about 70% then tried the car charger again.  Within a few minutes, I got the same overheating message.  It was not an overly hot day and the car A/C was set at 68 degrees.  
    This morning (with the battery at about 85%) I tried to use the Navigation without the car dock while charging and got the same results...the phone battery overheated and I had to unplug the charger. The battery temperature reached 116 degrees. (also, the battery level was also dropping while using the Maps or Nav application even though it was hooked up to the car charger).  
    I'm very disappointed with this situation since I was hoping I could replace my old Garmin GPS with the Charge.  But between the phone dimming the screen while running on battery, and having a depleted battery in the phone at the end of the trip, its just not a viable option.  I really like this phone, but I'm running against the "return" clock.  
    Any ideas?
    Could this be a software problem that will be corrected by an update in the future?
    fyi:  other Charge problems in the last 5 days:
    - dropping audio on calls to other Verizon phones.
    - use of camera flash causing the phone to reboot.
    (I do have the 'class 4' 32gb card in my Charge)
    Thanks in advance,
    Rich

    Jerry:
    Yes, the phone is charging while in the car dock.  I confirmed it both under the "about phone-status-battery status" menu and by my battery widget.  By watching the battery widget, I also noticed that the voltage steadily increased over the ride home.  It started at about 3.90 volts and ended at 4.02 volts.  I don't know if that is significant.  This time the battery did not overheat.  The Max temp was 110 degrees, but no notice to disconnect came up.  This might be because the sun was behind me on the drive home rather than beating down on the dash like it was this weeked.
    I've ordered a cheap universal dock from Amazon for about $15.00 which clips onto the a/c vent.  I want to see if this keeps the temperature down.  If this works, I can still return the fancy-schmantzy Samsung OEM car dock. (The car-dock interface wasn't that impressive anyway).
    Please let me know if the volt change means anything.
    And thanks again for your help!

  • Can I leave my mac book air plugged in all the time at work, without damaging the battery?

    I know people may have asked this questions many times, however I intend on using my mac book air at work and would like know I I can leave it on powered on in the office and the unplugged at night?. Would it damage my MacBook?

    Yes. It will not damage the battery. You do not need to unplug it at night. If you use it from the AC charage all the time, then about once every two months you should use it on battery power until the battery drops below 20%. Then fully recharge the battery after which you should allow the battery to "rest" for about one hour. It is OK to use the computer during that time but do not yet connect the AC adaptor. Follow this practice and your battery should have a good life.

  • Running Captivate 8 on a Macbook and I am unable to import Powerpoint 2011 (which is up to date) files or slides.  I get an error saying that either the file is damaged or I am using an older version of PP....which is not the case.

    Running Captivate 8 on a Macbook and I am unable to import Powerpoint 2011 (which is up to date) files or slides.  I get an error saying that either the file is damaged or I am using an older version of PP....which is not the case.  I tried creating a very simple PP file with just a few words on one slide...ran a compatibility check and all was good.  Still could not import that simple slide into Captivate.

    OK...found out it did not like me saving as a *.pptx.  When I save it as a *.ppt file it imported in correctly.  Is this what I will need to do moving forward?  I am not sure if I am losing any functionality in the process...

  • Is anyone having problems with the battery drains quickly and the iphone4 heats up in use and in charging after upgrading to 5.1.1?

    Is anyone having problems with the battery drains quickly and the iphone4 heats up in use and in charging after upgrading to 5.1.1?

    I have had the same problem but I seem to be getting somewhere to fixing it!!! My battery was going down at 20% an an hour now its 10% with constant use and 5 in standby !!! So improvement all round
    First I did a restore then I drained the battery i started to charge it and when it came on I turned the phone off completely and let it charge to 100% I then left it for a couple of hours on charge at 100. I saw no improvement after 1st drain so I repeated the drain battery and charge steps again with the phone turned off when charging and have seen a very big improvement. I am going to do it again tonight and hopefully problem solved!!!!
    The next issue is iMessage as that's playing up and wifi drop out
    Good luck

  • MBP Battery Maintenance Using Cinema Display

    When using MBP in clamshell mode I read many report no easy way to discharge the battery monthly to preserve it as recommded.
    I find without the power supply connected I use my 2011 MBP & Cinema Display in mirror mode with the MBP cover ajar.  If wanted the MBP screen brightness can be turned down also.
    Using the MBP & Cinema Display in mirror mode without the power supply connected will run down the battery in not so many hours.

    NO,   youre NOT supposed to do that!
    There is no calibration of current Apple portable Macbooks with built-in batteries.
    http://support.apple.com/kb/ht1490
    There is no battery calibration with current Apple portable Macbooks with built-in batteries. Lithium batteries have essentially a 0-‘memory’, and all such calibration involve the estimations fed to the system controller on the SOC (state of charge) of the battery over long periods of time as the battery degrades. The software based battery controller knows the battery's characteristics, or SOC and adjusts itself. This is why there is both no need and purpose to periodically deeply drain your macbook battery, since it doesn’t affect the characteristics of the battery, and further still deep discharges are something you should not do on purpose to any lithium battery.
    Portables with built-in batteries
    Current Apple portable computer batteries are pre-calibrated and do not require the calibration procedure
    MacBook (13-inch, Late 2009) and later
    General consideration of your MacBook battery
    Contrary to popular myths about notebook batteries, there is protection circuitry in your Macbook and therefore you cannot ‘overcharge’ your notebook when plugged in and already fully charged.
    However if you do not plan on using your notebook for several hours, turn it off (plugged in or otherwise), since you do not want your Macbook ‘both always plugged in and in sleep mode’.
    A lot of battery experts call the use of Lithium-Ion cells the "80% Rule", meaning use 80% of the full charge or so, then recharge them for longer overall life. The main quantified damage done in the use of Lithium Ion batteries are instances where the internal notebook battery is “often drained very low”, this is bad general use of your notebook battery.
    All batteries in any device are a consumable meant to be replaced eventually after much time, even under perfect use conditions.
    If the massive amount of data that exists on lithium batteries were to be condensed into a simplex, helpful, and memorable bit of information it would be:
    1. While realistically a bit impractical during normal everyday use, a lithium battery's longevity and its chemistry's health is most happy swinging back and forth between 20% and 85% charge roughly.
    2. Do not purposefully drain your battery very low (10% and less), and do not keep them charged often or always high (100%).
    3. Lithium batteries do not like the following:
    A: Deep discharges, as meaning roughly 10% or less. Avoid this in all instances if you can. This is hard on your battery.
    B: Rapid discharges as referring to energy intensive gaming on battery on a frequent basis (in which case while gaming, if possible, do same on power rather than battery).
    C: Constant inflation, as meaning always or most often on charge, and certainly not both in sleep mode and on charge always or often.

  • Water damage - replace battery?

    I stupidely managed to drop my Iphone 4 into a toilet the other day, leaving it for the time being useless. I did a lot of research online surrounding the topic, and left it in a sealed bag of rice for a few days. Ensuring it was completely dry, i tried to power it on with no luck. However, when i plug it in the charger, the Apple logo appears, sometimes blinking. I also manage to get the screen where it asks to plug it into iTunes by holding down the home button. I then tried to restore it in iTunes, but an error message was shown.
    I have then unscrewed the cover on the back, and taken out the battery. Despite the battery being out, all of the above was still possible, meaning it is being powered by the charger alone.
    Does this mean that replacing the battery with a new one could solve the problem? Or should it have been able to boot up fully using only the charger if it hadn't been in the water?
    Any answers are much appreciated.

    Replacing the battery in a water soaked iPhone is worthless. The water is going to cause corrosion which will cause the iPhone to become inoperative with or without a new battery.
    Instead take it to Apple and get an out of warranty replacement for it. Expect to pay for the replacement.
