Use power adaptor or battery

When to use which (Macbook Pro)?  Use the battery at all times and drain then recharge or just when an outlet is not available? 

That was copied and pasted from the article named above under the sub heading "Standard Maintenance".  I did read that.  But that does not really describe how I use the computer.  I do not travel with it much.  I use it more like a desktop.  I purchased the notebook because of it's small footprint and portability.  I use it in various places around the home on a daily basis.  Wherever I am there is an electrical outlet handy.  If I follow the principal of discharging and recharging once per month then I would be using the power adaptor almost constantly.  Is this truly recommended?

  • Power adaptor and battery HOT!

    This is the message I sent to Apple a few minutes ago. Maybe some of you can have some answers as well. Thanks!
    "Dear Apple,
    First of all, I would like to kindly express my apologies for using the feedback form to send you some thoughts about my MAC. I did not know who else to address to.
    I have bought my MAC in September 2009, through the Apple Store online. It has been delivered in Norway, where I am living in the present.
    Unfortunately, I have never been very satisfied with it, due to two main issues.
    First, I have noticed a problem with the battery and power adaptor since the very first day. They are both heating up very fast, after just some minutes, and then the mac is really, really slow (even if I have just one open application). I have tried a few times to go to a service provider in Oslo, but they said it's working fine. The first time I had a visit with a service was in the first week after I bought it. Then, when I had this screen problem, so I took advantage and I asked them to check again the battery (they had it for a week or two). They said it was fine. A few weeks ago I visited 3 different services with the same issue - no problems found.
    Of course one could say that this is the proper way of working of a mac, but how can a mac work so slow when they all say it is so fast? I have asked around and none of my friends had a similar problem, since they've purchased it.
    I decided to write you now due to the fact that a few days ago I had to use a friend's mac for some hours (which is older than mine, a simple MacBook; plus, he uses it much often than me). It was working perfectly! Not at all slow, no heating.
    Then yesterday I had my power adaptor plugged in for half an hour - then I saw that the mac was not charging (how come?). When I touched the power adaptor, I literally burned my finger. Of course I got scared as well. I tried to change the power adaptor with another one - it did not get so heat up, but the battery of the mac was still burning, as usual. I used to keep my old PC in my lap, with the mac it was always impossible, unfortunately.
    With lots of regrets I am writing this message. I have never felt that I had a 'real mac', like the other friends of mine, although I was so excited in the beginning. I sincerely hope that I am a unique user.
    Now I am planning to sell it to someone (I don't think I can get even half of the price now, since it is pretty old) and get back to some usual PC. With all the regrets in the world, again, because some of the features were indeed really cool (like the trackpad, for eg).
    Thank you for reading this! Good luck with your future products! And may God rest in peace Steve Jobs, I hope the business will not be affected.
    Best regards,
    Cristina Moldovan"

    45W is definitely not correct for any 15" model. Here are the correct model power adapters:
    http://docs.info.apple.com/article.html?artnum=75448
    Yes it can hurt and potentially create a fire hazard if you use the wrong adapter. Get the correct one.
    As for the display resolution the 867 Mhz TiBook was released on this release as a:
    http://support.apple.com/specs/powerbook/PowerBookG41GHz-867MHz.html
    1280 x 854, 1152 by 768 supporting display. Check the inside of the machine's battery bay to verify it is an M8858LL/A. If it isn't then this might be a bit of a Frankenmac.

  • Using power adaptor charger while playing iPod

    I have a charger for my iPod Mini. I think it's called a "USB-based power adaptor." When I got it about a year ago it cost about $20. Uses a cable for the iPod into it and then plugs into a standard outlet.
    I am also able to run my iPod through one of my more high-end stereo systems. A great advantage, particularly for "home recording," to listen and get full stereo sound.
    The question is:
    Can I use the charger adaptor while the iPod is playing? Either through the stereo system or using the iPod just by itself?
    It would seem that should be no problem. Wouldn't it be the same principle as using an iPod "dock?"
    If I can do this, the nice thing would be that I could keep my iPod fully charged while playing. Either through the stereo system or playing just the iPod alone.
    Could any harm be done by doing this?
    Thanks in advance.

    In theory, it shouldn't do any harm. The reason I added the qualifier is that its possible that a non-Apple charger could in some way, not be quite up to spec and could behave oddly. Of course, Apple chargers can go bad, too. iPods will stop accepting a charger once they are fully charged. I have used chargers while my iPod has been connected to speakers with no difficulty and no harm to the iPod.

  • Track pad very irratic while using power adaptor

    Using a 65 watt power adaptor on my Macbook Air, which requires only 45 watts. Charges the batter fine, but I cannot use the trackpad while it's plugged in, unplug it and it works fine. Extrememly annoying.

    Does the trackpad operate correctly using the MBA 45W power adapter?

  • Using power adaptor plugs with iBook charger

    I bought the iPod USB Power adaptor from Singapore and it came with a power adaptor plug that is used in the States. Can I use that plug and slot it into my iBook charger? Will it work? I've tried putting it in and the connection's fine but it doesn't look like a perfect fit externally.

    967/3413
    Hi Ernest,
    Three criteria must be respected:
    1) Voltage and Power compatibility:
    The electrical specs on the iPod USB Power adaptor must match the ones that come out of the iBook charger. (you may need a magnifying glass, but they read somewhere, it's the law) Most probably all this stuff is International 100-240V/50-60Hz, but you must make sure.
    However the Amperes (or the Watts) values often differ, so watch this carefully.
    2) No loose contact:
    Although shapes can look weird, if at least contacts are always touching tightly, that's fine.
    3) Security:
    If you can see enough metal for the cat to put her nose on it... ... ...
    Another solution is to warn the cat
    --> Find a shape adapter if electrical specs match:
    Adapters are not all multiple, expensive devices. Find a cheap one that fits only between Singapore and the US.
    Hope this helps.

  • Using power adaptors interchangeably

    Is it Ok to use the same power adaptor/power brick with i books and powerbooks. I have several laptops, can I just interchange the power adaptors?
    thank you joanlvh

    You can do it, but it's not recommended.

  • Trouble using Power Adaptor to charge iPad2

    The 10W USB Adaptor supplied with my iPad2 doesn't seem to work  When I plug it in (using a UK plug which it slots into) it does not charge the iPad.  I have another plug which the USB cable slots into, and when the iPad is connected to a power socket via this plug, it charges but the plug gets hot very quickly.  Is this OK?  I don't like to leave it plugged in this way for too long, so it will take ages to charge it fully.  Do you have to use the USB Adaptor supplied - is it the best way to charge?

    The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
    Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
    At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night. Also look at The iPad's charging challenge explained http://www.macworld.com/article/1150356/ipadcharging.html

  • Using ac adaptor with battery

    just wondered- if ac adaptor is plugged in, once battery is fulluy charged, does the battery cut out and all power is received from the ac adaptor

    Based on my experience no. However, you can remove the battery anytime the machine is plugged in without ill effects (other than if the A/C should suddenly lose power). You will though find that cycling the battery charge and draining it following these directions can prolong its life:
    http://www.apple.com/batteries/
    Consider having power via A/C and battery a sort of backup. If the power should be lost when a file is being created, you may not be able to recover it.
    If the power should be lost while the operating system is running the directory may get damaged*:
    http://www.macmaps.com/directoryfaq.html
    So is it good to have both plugged in at the same time? Some would argue one way or the other based on both of the above being true.

  • Battery charging and power adaptor issues

    I'm having slight issues with both my power adaptor and the battery itself.
    First I think I have cord issues as the light status can change from dim green to red or bright green if I move the cord around.
    Second, my MBP is having trouble recognising if power is going to the battery or if it's charging etc. It can recognise if there's no adaptor connected at all, but if there's an adaptor connected, it has trouble seeing if there's power coming from the adaptor even if the light is on. I.e. it can stay at 100% and supply comes from the power adaptor and then suddenly drop to 80% power and start charging agan. One issue that happened earlier today was the adaptor was connected, and the battery indicator was at 100% with supply from the adaptor. Suddenly the MBP shutdown, and when I rebooted it was at 17% (I've tried repeating that in case of a dodgy battery but I couldn't)

    If that doesn't help, the problem could be the adapter, the battery, or the I/O board (or a couple of less likely things). If you can borrow another adapter and/or battery, try them to see where the problem is. Or, if you're near an Apple Store, take it in and they'll diagnose it for you (for free, but they will charge for repairs if you need them and don't have AppleCare).

  • How to use power not battery?

    Just got new Mac Book Pro--my first laptop.  I am confused about the power cord and the power adapter.  How do I run the laptop using power connection instead of battery?  The power cord only plugs into the adapter, not the machine.  I'm off to a great start--can't seem to figure this out.

    Yes, in fact it's a good idea to use the AC adaptor whenever it's convenient. There's no harm done to the computer or to the battery. See more:

  • Using ac power adapter vs. battery on MacBook Pro

    I purchased a 15 inch MacBook Pro with retina display a couple months ago.  Most of the time I use it with the ac power adapter.  Is there any harm to the battery life if I never left the battery drain down some and then recharge it? I have come to understand that when the battery is fully charged and plugged in to an outlet the battery is basically on standby.
    Thanks

    If you use it mostly on AC, then once every one or two months you should use it on the battery until the battery runs down to about 20%. Then reconnect the AC so the battery can recharge.

  • Can I use a Macbook power adaptor for MacBook Pro ?

    Hi,
    Is its safe to use a power adaptor from a Macbook (white), to charge my Macbook Pro.
    The difference is in the output of the adaptors: 3.65A (Macbook) vs. 4.56A (Macbook Pro).
    Thanks,
    Ori

    In the past, I had an IBM Thinkpad laptop, when my adapter broke, I borrowed an adapter from a colleague. This adapter also had a lower capacity than the original adapter (I don't remember by how much).
    It ran really hot but the Thinkpad would run fine on it, though it would only charge the battery if I turned it off... So either charging the battery or working with the laptop...
    I'd say use it until you get the chance to buy a new one...

  • Charging battery: usb-computer vs usb-iphone power adaptor

    My new 3GS charged from shutdown to full using the Apple power adaptor that came with the iPhone, in only a few hours. Seems fast. And I read that the computer gives a trickle charge. In general, a slow trickle charge is preferable, if one is not in a hurry.
    Does this imply that the wall adaptor does NOT give a trickle charge, and might be harsher on the battery, even though faster?
    IF there is a difference between the computer and wall adaptor, then, I will use the computer (when it's not sleeping) to charge, rather than the power adaptor.
    Thanks,
    Sonny

    This link provides info on how the iPhone's battery is charged, regardless if connected to the wall charger or to a USB port on your computer, or to a vehicle charger.

  • Using the Power Adaptor

    Greetings,
    When using the power adaptor should I take out the battery?
    The reason why I ask this is that I use to have a Sony laptop running Windows 2000 and had continual problems with the battery not holding its charge. I was eventually told by the Sony technicians that once the battery was fully charged I should remove it from the laptop whilst running from the mains.
    Thanks in advance

    Hello!
    You might try posting this in the appropriate Powerbook Forum. We don't know much about laptops here in the G4 Tower forum.
    If you have a G4 iBook post here.
