Macbook Pro on battery power

I am a brand new Mac user so please forgive me if this question is obvious. When my MacBook Pro is on battery power and I leave the computer alone for an extended period of time (with the lid still open), the battery is dead when I return. Is this normal? Under Energy Saver in System Preferences, I have it set to "Computer Sleep" at 10 minutes when on battery power. Thanks for the help!

hai all,, i've already bought mbp last year,, but i just got to know about calibration things right now,, quite a surprise for me,, i've read so many articles about it,, from many forums, and now i got confused,, cause there are too many opinions about what to do and sometimes it differs each other.. which one that i should believe in?
my 2 simple questions are
1. after the battery is fully charged, should we unplug the magsafe or let it plugged in?
2. some said that we should make cycle counts at least 1-2 times a week, is that true?
right now my cycle counts are 172,, cause everytime my battery is fully charged, i always unplug the magsafe,, lately i was thinking about that cycle count,, it's such a waste if i let it counts,, should i still plug in the magsafe? if i do,, where do the power that my mbp using come from? the AC adaptor or still from the battery (don't it make my battery bulge?) ?
that's a lot of questions,,, sorry,, i'm just too curious,, give me the right answers please,,
for addition my battery just lasts for 4-5hours everytime it has been fully charged,, not 9 hours like the web said... is that the effect of 'never calibrating my battery'?

  • Web pages won't load when MacBook Pro on battery power

    My sister bought a MacBook Pro in January. She switched from a Dell laptop. Everything was great until a few weeks ago. When she would be on battery power, she would have a hard time getting websites to load with Safari. I suggested she use Firefox and see if it made a difference. It didn't.
    She can try to open a webpage and it will try to load for a long time (3-5 minutes). If she plugs in the power adapter, the page loads immediately. She still has her Dell laptop and the same websites load with no problem when using the Dell on battery.
    I told her to call Apple since she has Applecare. Apple sent her a new battery even though they told her they didn't think it was that. It didn't make any difference. They told her it was her internet connection, but it works fine if the MacBook Pro is hooked up to the power adapter and her Dell laptop loads internet pages without any problem while on battery power. Then they tried to tell her just to use the power adapter all the time. She told them if she wanted to be tied down to a power adapter she would have bought a desktop. (Not a very good comment by Apple in my opinion.)
    She doesn't live close to an Apple Store to take it in.
    This is just the weirdest thing I have ever heard of. All of her other applications (Office, Photoshop, iTunes, etc.) run just fine on battery power. It is just the internet. At first I thought it might just be secure sites, like banking, but she couldn't get MacNN or Versiontracker to load while on battery power.
    Does anyone have any ideas?

    You'll probably find an Airport aerial issue. Does she find that Airport reception (a better guide is shown in Internet Connect) will drop dramatically when she disconnects power? If so contact AppleCare again and give them this information under the same case number she wuold have gotten when they replaced the battery.
    PS In space, no-one can hear you scream!

  • My 13.3" macbook pro will not power up.The battery indicator light does not come on.The Mag safe charging light flickers green and red dimly.I had a cell phone connected to the USB port.

    This didn't work for me, so I did a bit of searching and TONS of pages later in google, I found an answer. Here are the steps for people who also were in my situation:
    1. Take off bottom case
    2. Unplug battery - blurry image here: http://i.ytimg.com/vi/03cC79r5Dx4/0.jpg
    3. Press and hold power button for 5 seconds
    4. Plug a charger in, and it should start booting up
    5. After shutting down again, reconnect the battery and close the case up
    6. It works! (hopefully, if you guys had the same situation I did)

  • MacBook Pro - After Battery dies I'm not able to type in login window, until forcing a restart

    Hi, as mentioned in the header : MacBook Pro - After Battery dies I'm not able to type in login window, until forcing a restart
    After the battery drains to 0% the computer switches off.... *Makes sense*
    Once I put the charger power chord back in for an extended period of time I hit the power button and then see the login screen.... *Makes sense*
    However it won't let me type into the login box therefore having to force a restart and lose any saved data or data open when it died of battery. *WEIRD*
    This happens every time my computer runs out of battery. I understand that obviously not letting the laptop die is a good idea, however it seems like there is something wrong as it allows me to login yet won't let me type anything...
    Any solutions? Anyone else experience this?
    I have an early 2012 MacBook Pro - 15 Inch Screen.

    Hi s4mboy,
    Thanks for visiting Apple Support Communities.
    I'd start with resetting the SMC and PRAM on the MacBook Pro:

  • Would it be bad if i left my Macbook Pro on the power supply constantly?

    I wanted to know if there was any bad that comes out of leaving my Macbook Pro on its power supply and charging 24/7?

    Yes. Do not do that.

    If for some reason you want your MBP to be up and running all the time, plug in the charger but remove the battery. That's how they do it in the Apple Retail Stores. Before removing the battery, run the computer without the charger attached until the battery is about 50% charged. That will maximize its useful life while it remains in storage.

  • Why doesn't the Macbook Pro's battery life last?

    Why doesn't the Macbook Pro's battery life last anywhere near 5 hours, as advertised?  This is my second one and it lasts 2.  It's false advertising, and Apple doesn't seem to making a big deal or know anything about it, which i'm sure they do.  Since their general practice is to deny problems exist in all their products, i'm here to make it known that the most recent Macbook Pro has a severe battery issue and it needs to be addressed.
    I'm running OS X 10.8.3, Bluetooth is off, and haven't installed any third party software.

    My MacBook Pro is over a year old and still gets 2.5 to 5 hours, depending on how intensively my application activity is hitting the CPU and disk. Remember that battery life depends on usage and component loads. You could get 1 hour editing HD video since it would hit all cores and slam the disk constantly, or 8 hours in a cabin in the woods with wifi and Bluetooth turned off, only writing text files, and with the backlight turned down and no disc in the drive. You should check Activity Monitor to make sure you don't have some processes using unusually high amounts of CPU for long periods of time (like browser tabs running Flash ads in the background, chewing up CPU and battery power without even being seen).
    Like mende1 says, there are not huge numbers of Mac users getting only 2 hours, or the world would have heard about it by now and MacBook sales would be down. If you are only getting 2 hours there is something going on local to your machine or usage habits.

    That's not strictly true. Apple has often announced updates or repair/exchange programs to address various problems that had come up over time. Maybe not always, but it does happen. They also have often helped me and my friends when we brought in Macs that were out of warranty and had problems. They had no legal obligation to work on our Macs for free, but they did anyway.

  • Just bought a mid 2012 13 in macbook pro. Battery life is only 3 hours. Thoughts?

    Just bought a mid 2012 13 in macbook pro. Battery life is only 3 hours. I was under the impression that it would last 7 hours. This is with normal internet browsing and text editing. my brightness is not all the up and bluetooth is off. Thoughts?

    I have a MacBook pro that has power issues and will not start but the hardrive is fine.  I do not want to lose all of my files so I was wondering if it's possible to transfer my hardrive from a older Macbook pro to a new one if I were to purchase a new one?  Also, the software is not updated as the computer hasn't worked for about 2 months. 
    Also, if it is possible to transfer the hardrive, would my iTunes music transfer as well?  It is not saved in the cloud.
    Thanks for your help, it is much appreciated.

    You computer is probably perfectly repairable, but if you want a new one anyway, it is perfectly possible to transfer the data from the faulty one.
    But it would be a mistake to simply put the old HD in the new computer.
    These are the steps:
    Remove Hard drive from faulty computer. (very easy on Unibody MBPs, do-able but not so easy on older MBPs)
    Put it in a cheap enclosure
    Connect it the new computer
    Boot up new computer.
    If the new computer has never been run before the Setup Assistant will ask if you want to import your apps, data, settings etc from either another mac, another HD connected to the Mac or a Time Machine back up.
    Obviously chose the second option (another HD connected to this Mac) and follow prompts.
    If the new computer has already been run (so Setup Assistant doesn't run when you boot it up), you will need to use Migration Assistant...or run the installer again so that Setup Assistant runs again.

  • My sister spoiled water into my macbook pro and the power went off in two seconds. I took off the cover and dried the water with tissues. Still it doesnt work. What do i do?

    My sister spoiled water into my macbook pro and the power went off in two seconds. I took off the cover and dried the water with tissues. Still it doesnt work. What do i do?

    Do you mean when the water was spilled on it, it shut down?  That would indicate a major internal short occured.
    Really, I'd say you need to take it into Apple or an Apple authorized repair center and get it looked at.  Odds are you've got a significantly damaged device that will require professional repair and parts replacement to get working again.

  • Sleep light is on but MacBook pro will not power up

    Sleep light is on but MacBook pro will not power up

    Hi a,
    If the sleep light is already on when you try to start up, that means the MBP isn't shut down, so cannot start up. Hold down the power button for 5-10 seconds to shut it down, then try starting up.

  • Need to get a new MacBook Pro 17" Battery..ideas?

    Hello all,
    A few days back my MacBook Pro's battery died and I noticed it was swelled up pretty bad.
    Needless to say, I desperatley need to get a new battery (MacBook Pro 17 " battery, id A1189), but am a wee bit scared to fork out £100, plus money is a wee bit tight right now.
    I'd like to know if anyone here knows of anywhere where I could get a replacemnt battery at a good price? I'm based in London so it would have to be in the UK.
    I've googled my brains out and found that Duracell Direct to a replacement at £74.
    Any advice or directions to a trusted, decent priced vendor would be great
    Regards,
    Rik

    One thing to try is to make an appointment at the genius bar and ask them about the battery. Take both it and your Mac in. There used to be a program called "Battery Update" that replaced swollen batteries, but it is no longer in effect. However, Apple has frequently been very generous about replacing swollen batteries or selling a replacement at a discount. They should also recycle the battery for you.
    Whatever you do, remove the battery immediately and don't use it any more. It could cause permanent damage to your Mac. It may leak, so place it in a plastic bag so it can't damage anything.
    It is entirely at Apple's discretion what they might do, but they did give me a free replacement for a 3 year old battery with 265 cycles on it. You have nothing to lose by asking--the worst they can do is say no.
    If no joy, you might want to look at OWC's battery listings. I believe they ship to the UK, and they currently have some special deals along with their line of NuPower batteries. I bought a NuPower battery for my iBook, and it has performed very well. I've heard mixed reviews about other third party batteries, and have heard nothing whatsoever about anything by Duracell.
    Good luck!

  • HT3964 MacBook Pro will not power

    My MacBook Pro will not power on. It was charged and then just shut off and power cord does not even light up. How do I fix this?

    jpg8,
    which model MacBook Pro do you have, and which version of OS X is installed on it?

  • Macbook pro goes into power save mode with dell sp2208wfp monitor.

    I have a macbook pro and am trying to connect it to a dell sp2208wfp monitor, I am using a hdmi cord and it goes straight to power save mode. My mac works on my roommates monitor and his PC works on my monitor but my mac doesn't work on my monitor. I've read the other forums and have found nothing. One guy suggested plugging the mac into a power source still nothing, any solutions before I try and sell this thing on craigslist?

    Had the same issue a few months ago when I tried connecting to external monitor, it is only possible to run external displays from a Macbook Pro while the power cable is attached, if you try and connect to external display without having the charger attached the external display will flash your desk top for a second and then your Macbook Pro will go to sleep.  Hence connect your charger every time you wish to connect to external display, its not a problem with your Macbook Pro, it's just the way of Apple. Hope that helps.

  • MacBook pro won't power up! Acting asleep, black screen, fans don't fire up. Light nr catch pulsing, have taken batt out and reset but still blank screen, help!!

    MacBook pro won't power up! Acting asleep, black screen, fans don't fire up. Light nr catch pulsing, have taken batt out and reset but still blank screen, help!!

    You may want to try this.
    Solution A
    Start up your MBP while pressing Option (alt)|, Command, P, R until your hear 3 chimes rather than 2 as indicated by apple. This worked for me the first time.
    Solution B
    Start your MBP while pressing Option (alt), Command, S
    Hold until you see the computer automatic routine. When it finally stops type the following followed by "return":
    fsck -fy
    It will probably indicate some problem related to "pcscd.pub" (should be 16 instead of 17). I haven't figured out what this means but somewhere in the Internet i read it is related to scan cards...
    More importantly this routine will fix any problems with your HDD similarily to disk repair. When it ends, it will tell you if it has fixed/modified anything. If it has, run the routine again by typing again "fsck -fy"
    Lastly, reboot by typing "reboot" (followed by "return")
    Solution C
    Start up your MBP while pressing option (alt), command, S
    hold keys until you see computer commands scrolling
    when the routine stops type the following, each line followed by the "return" key:
    mount -uw /
    chmod 775 /
    chmod 1775 /
    reboot
    After which your computer should reboot on it's own.
    Each of the above has worked for me at one time or another. Once your computer has rebooted from the DVD you can reinstall OS X. If your problems started after installing 10.5.6, then I don't suggest updating until 10.5.5.
    I'm very very disappointed with my 2007 MBP, it started to give me problems after 1 year. had to change the HDD and lately when I isntalled 10.5.6 it suddenly refused to start up., My previous Mac laptop (2003 866Mhz) worked for 4 years without a hitch. Ironically I've had to use it to access the internet and find solutions for my current MBP.
    best of luck
