When using power adapter, what to do with the battery?

Hi,
I own a macbook (mid july 07 model). Most of the time (99%) my macbook is on my desktop and the power adapter is plugged in. I am wondering in my senario, is it better to leave the battery in or out? I understand that there will be performances differences but I can live with the fall in performance when the battery is out, as I don't run heavy apps. Would't it be battery for the battery if I leave it 50% charged and tucked away? I read it from the apple website that if you don't intend to use the battery for 6 mths, its better to do it this way. However, I read the other post in this forum (http://discussions.apple.com/thread.jspa?messageID=4883352&#4883352) and people suggested to leave the battery in as it doesn't make much of a difference. This kind of left me hanging, in or out? What do you guys do with your batteries? Care to share some experiences? or advise? Thanks.

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.

  • Noise when using power adapter

    I've got a 1.25Ghz Powerbook 15 inch. It's been pretty noisy lately and sounded like a high pitch type mosquito sound. I just unplugged it to use battery power and the sound stopped. Now it's quiet as it should be. Does anyone know what may be causing this noise?
    Also, what happens when I reset the power management on a powerbook? Do I lose any settings?

    I had the same irritating 'mosquito' buzzing sound when plugged into my new 65 W AC power adapter (my previous one died) and the charging was intermittent and would require plugging & unplugging to get it to start charging again. I reset the PMU (power management unit) -- see BGreg's link above -- and it now working well. I hope it works for you!
    cheers

  • My Macbook Pro display flickers when using power adapter

    I purchased a new power adapter for my Macbook Pro (late 2011 17 inch) from Other World Computing and now the display flickers intermittently when attached to the new power adapter. There is no flickering when not attached to the power adapter or when attached to the old power adapter.
    Any ideas on fixing the new power adapter? I would rather fix the problem if it is simple.
    Thanks for the help.

    It doesn't affect the battery. You can use your MacBook Pro plugged in all the time without damaging the battery. You only have to be sure that you unplug it and run a battery cycle (drain the battery without letting the Mac turn off and charge it fully) at least once a month to keep the battery life.

  • Remove battery when using power adapter?

    Just picked up a 12" PowerBook G4 on eBay. Is it best to remove the battery as I use the power adapter exclusively?

    Whether you remove the battery or not, the battery will die an early death if it is never used.
    Removing the battery deprives you of its value as an uninterruptible power supply if the AC power should fail. In a power outage, if the battery is removed the computer instantly shuts down, and whatever you were working on but hadn't yet saved is irretrievably lost. If the battery is in place and charged and the power goes out, the machine instantly and automatically switches over to battery power, and you continue to work as if nothing had happened.
    Even if you never need to work away from AC power, it's worth unplugging the AC adapter cord from your computer for an hour every day or two, just to give the battery the exercise it needs to keep on functioning. That way you'll continue to benefit from its uninterruptible-power-supply services as long as possible.

  • When using Firefox today a strange page with the title wonderhowto showing video instruction appears and all other open pages are closed. I have minimalised this stranger to the screen base and it now shows there with a mini firefox attached!

    Please bear with me as I am quite new to computers. Early today on start up I was asked to upgrade an Apple app. I declined as I did not have time.
    I opened Firefox as usual and went into several sites mail news etc and all seemed fine. Late morning this strange and quite professional looking video instruction page appeared full of photo's and instructions etc, the page took over the whole screen I thought it was strange so I closed it and all my open Firefox sites had gone. This has now happened several times. I have now noticed that when it is up there is a website address at the bottom of the screen. I tried to copy and paste this but it would not let me. There is a name scorecardresearch.com. Does this strike a bell with anyone?

    Hello,
    My name is Bryan Crow, and I am the CEO of WonderHowTo.com. This problem was brought to my attention this morning by others who have reported the same problem to our contact address: [email protected] I'm very sorry to hear this is happening.
    I assure you this is not something our website created or installed on your computer. Most likely it is some form of spyware or virus that is opening our website in order to hide it's true purpose. We are a large and trusted source for how-to articles and videos, so there is no reason we would choose to annoy people with such an obnoxious and intrusive behavior. Frankly it's very upsetting that someone would create malware that directed people to our website.
    Naturally, our team would like to do whatever we can to try and find the culprit behind this so we can report them. If any of you can provide me with additional information by emailing [email protected], it could help us get to the bottom of this.
    Specifically:
    * Have you installed or updated any Firefox Add-Ons recently (go to Firefox -> Add Ons to see the list of add-ons you have installed)?
    * What Firefox Add-Ons do you have installed?
    * Have you tried running a virus or spyware scan on your system? If so, which software did you use and did it help?
    * What URL is opening up when you see WonderHowTo, and what exact time of day (and in what time-zone) did you see it?
    Thank you for your help.

  • HT3743 got a new iphone 5 what is up with the battery it drains quicker than my bath

  • Is this power adapter (12W) really compatible with iPod shuffle?

    Hello,
    I'm just wondering if the 12W power adapter is really compatible with the iPod shuffle 4th generation.
    (http://store.apple.com/us/product/MD836LL/A/apple-12w-usb-power-adapter?fnode=74)
    It says it is compatible, but it doesn't make sense to me. Because iPod shuffle is so tiny, I fear that it would burn out if I plug it into a 12W. I understand that the 5W version is compatible but 12W seems interesting.
    What do you think? Do you use 12W for the iPod shuffle, too?

    It works fine and will not damage the Shuffle. The Shuffle will draw only the power it requires.

    When using compressor voice is not sync with video. What causes this and how to fix it, please?

    Although you say you have let the battery drain, was it for long enough? Since nothing else that you've tried so far has worked, I suggest that you leave the iPod unplugged for at least four days, preferably a week. That way, if something is stopping the iPod from turning the screen on, then whatever it is will drain the battrey. However, since the screen isn't on, that may take longer than if the screen was on.
    Then, after that time, plug the iPod into a power source and leave it alone for at least thirty minutes. Only after thirty minutes will it show any signs of life, but you should leave it until it is fully charged before trying to use it.
    If you get to this stage, the fact that the battery has drained will cause the iPod to reset when it springs back to life.
    Let us know how you get on.

  • HT201263 When my Ipod touch is in autolock I can only restart the device holding the sleep/wake button and home button at the same time for 10 seconds.  While in auto-lock it is using battery power and will do so until the battery is drained.  Whats wrong

    When my Ipod touch is in autolock I can only restart the device holding the sleep/wake button and home button at the same time for 10 seconds.  While in auto-lock it is using battery power and will do so until the battery is drained.  Whats wrong?

    - Try a reset. Nothing is lost:
    Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears
    - Connect the iPod to your computer and try to restore via iTunes. Try placing in Recovery mode if necessary to restore.
    - If you can't turn the iPod completely off, let the batter fully drain. After charging for at lerast anhour try again
    - If still not successful time for an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

    Hey aries35,
    I found the following that goes over troubleshooting the same issue for the iPhone. I know you have an iPad, but the steps should still apply:
    Perform the following steps:
    Restart the iPhone.
    Try another means of reaching the activation server and attempt to activate.
    Try connecting to a known-good Wi-Fi network if you're unable to activate using a cellular data connection.
    Try connecting to iTunes if you're unable to activate using Wi-Fi.
    Restore the iPhone.
    If you receive an alert message when you attempt to activate your iPhone, try to place the iPhone in recovery mode and perform a restore. If you're still unable to complete the setup assistant due to an activation error, contact Apple for assistance.

    I just wanted to leave a note that it's working now. I'm not sure if it was the latest iTunes update that got it working or that i decided to start a new library instead of using the one i had backed up on Windows 8 (it didn't occur to me to check using the old library when i re-installed iTunes). But if anyone is having this problem, it might be worth trying again with a new installation of iTunes to see if the latest update works for you, and if not, try using a fresh library instead of a backup (by fresh library i mean discard your old library completely and start a new library, not just restore as new iPhone, a whole new library).
