MacBook Pro Battery and CPU behavior

I realized, when i do not have the abttery inside the macbook, what i do not fotne, to save chargecycles, that my cpu wil not go above 1ghz. i observed this with the use of the coreduotemp application, wich can be free downloaded and monitors temperature and cpu speed of your macbook. i wrote to the developper, and he confirms that observation, so it is not an software bug.
First, i invite you to test this on your macs and report, and secound i would like to have a solution, i bought this mac for power, not for slow power. maybe someone knows how to disabe this PMU behavior, thx

This is not true! I use CoreDuoTemp as well and I can get the full power of my CPU on batteries.

  • Macbook pro battery and ac

    Can I use my macbook pro 15 early 2012 always with ac or this can damage battery?

    It will not damage your battery.  I do that all the time.  At least once per month use the MBP with the battery and let is discharge to about the 30% level and then recharge.

  • MacBook Pro Battery and BootCamp

    Hi.
    Does anyone have the answer about the battery life using BootCamp with a MacBook Pro? Only getting 1hour to 1.5hour using Windows Vista. Many thanks.

    Hi and welcome to Discussions,
    you might wanna try the Safe Boot options of Windows XP as described here http://support.microsoft.com/?scid=kb%3Ben-us%3B315222&x=10&y=11
    The 'Safe Mode' and/or the 'Enable Boot Logging' might show ehther this is a driver or a services problem.

  • 10.4.9 and hot macbook pro battery and fan noise

    Since upgrading -- the bottom of the macbook pro 15 is suddenly really hot...I mean, really hot...and the fan keeps coming on -- which NEVER came one with the previous version of 10.4....
    Any ideas??

    Since upgrading -- the bottom of the macbook pro 15
    is suddenly really hot...I mean, really hot...and the
    fan keeps coming on -- which NEVER came one with the
    previous version of 10.4....
    Same problem here, but replying the combo installer didn't do the trick -- before the 10.4.9 update the computer ran nice and cool, and fans only came on under heavy heavy processor load (with 'Fan Control' 1.1 at a medium setting). After the update, even with 'Fan Control' at maximum, the fans were suddenly going most of the time and computer was hot hot hot.
    I reapplied the update from the Combo installer, and reinstalled 'Fan Control' just to be sure, but I'm noticing the same problem still -- running almost no processor load and the computer is hot and the fans are whirring.
    Anyone have any other ideas? Cheers.

  • MacBook Pro - Battery and Trackpad Heat Issue

    Hi,
    I purchased my MBPro 15-inch in December of 08 (so unibody type). For the last few months, after a couple of hours, the trackpad becomes unusable. You can't "click" and navigating around the screen clicks and unclicks and is general extremely sensitive.
    When I remove the battery, it works fine (but you have to keep the power supply connected or it dies instantly). As of this week, when I replace the battery, it goes straight back to the problem. Previously, I would get 15-30 minutes of "normal" usage and then the problem would reassert itself.
    Should I just get a new battery? Is this the kind of issue that Apple had previously on non-unibody MBPros and required a mass recall and replace of batteries?
    Any suggestions would be greatly appreciated

    Welcome to Apple Discussions!
    This is likely the same issue which resulted in a recall of swollen batteries (Battery Update). Have you carefully checked your battery for any signs of swelling or leaking? If you do have a swollen battery, stop using it immediately and get a replacement. You don't want to risk permanent damage to your Mac.
    The battery doesn't even have to be in use. Some time ago, someone posted a picture of a spare battery that had never been in a machine, but which had still swelled up and come apart.
    There seems to be some question as to whether this is to be expected of all these batteries, or if it is an indication of a factory defect. For this reason, people have had mixed results trying to get the battery replaced for free from Apple. Generally, if you've been able to get 300 cycles out of your battery, your battery is just considered worn out and your chances of a free replacement are remote. If this happens on a newer battery with fewer cycles, I believe decisions are made on a case by case basis.
    I actually hope that swelling is a characteristic of a defective battery and not something expected to happen to all of them. Especially since the new Unibody Macs now have a built-in battery that is not supposed to be user replaceable.
    Good luck!

  • Macbook pro battery and service from apple

    I have just bought the MBP online on the student package where you are supposed to get a free ipod nano by sending back a form to get the refund. I phoned apple about this and no-one knew what to do I was passed to 3 different departments then I was told to go to the apple website and download the form to send it back. I did this and when I got to the site there were lots of downloadable forms and none of them specified anything to do with student packages and free ipod nano's. I have also discovered that the battery doesnt seem to last very long and overheats. This is worrying me slightly as an over heating battery could be a fire hazzard and I spent just over 1400 pounds with upgrades at that price I would expect it to be running perfectly can anyone tell me if this is normal for the battery to overheat and is it normal for the battery to last less than a day. Also will I recieve terrible aftercare from apple all the time. every time I phone no-one seems to know what to do. the last time I called the guy actually tried to pretend he couldnt hear me to get me off the phone until he realised that he was caught out and the line was fine. it seems they will go to any length not to help you.

    how does the battery overheat? the mbp can certainly get hot, but if it is only the battery getting hot then you should call technical support
    operating time on battery depends on how heavily the system is being used, editing/rendering video flattens mine in 2-3 hours, but with casual use it lasts much longer
    you must order the ipod at the same time you order the mac, then once it is all delivered you submit a claim online and apple gives you back £95
    the terms are all on the website...

  • MacBook Pro battery had accumulated more than a 1000 charges, and stopped functioning unexpectedly. Went and got the battery replaced. Just saw that SMC Firmware 1.6 update deals with this. Possible to get my money back?

    MacBook Pro battery had accumulated more than a 1000 charges, and stopped functioning unexpectedly. Went and got the battery replaced. Just saw that SMC Firmware 1.6 update deals with this. Possible to get my money back?

    The firmware update corrects an error that may occur, however the techs would have checked the condition of the battery prior to installing a new one.  If the battery was questionable, the firmware update was really not too important.
    You can check the battery condition by going to the apple, left side of the menu bar, About This Mac, More Info, System Report, Hardware, Power and see what it says about Cycle Count, Condition, Capacity: Condition anything but Normal needs to be checked and may need to be replaced.
    The cycle count of 1,000 charge cycles is the typical life of a Lithium-Ion battery, the point at which the capacity drops to 80% of the as built capacity.

    Pretty nice change for those C2D's

  • Dota 2 and Macbook pro battery

    My early 2011 15 inch macbook pro battery drains while connected with 85w charger when i am playing dota 2. Dota 2 runs faily well with very little lag in almost high setting. Shouldn't 85w charger provide adequte power for gaming. Dota 2 is not even a very demanding game. I have only played few small 2d games in my pro and this may be the first time i am playing a 3d game. And also sometimes it doesnt drain even when i play 2-3 matches but most of the other times it drains in single match. I have yet to see it drain down 90% but still. What options do i have to fix this? I am graphic designer so i sometimes do video editing in my macbook pro and i m quite sure some of those renderings are more system hungry than dota 2 and no drain while doing that. Thanks in advance.

    What do you mean it didn't work? Are you having a battery issue that the update did not fix? Need some more info. If you look at the webpage that I linked to, it advises to have affected batteries replaced.
    Identifying an affected battery
    Affected batteries will have one or more of the following symptoms:
    Battery is not recognized causing an “X” to appear in the battery icon in the Finder menu bar.

    Battery pack is visibly deformed.
    Note: If your MacBook or MacBook Pro battery does not have any of the symptoms noted above, your battery does not need to be replaced.
    If you're replacing batteries every 3 months I would take a look at how you are maintaining your battery. Are you calibrating it when it arrives and then every 6 to 8 weeks afterword? Are you running graphically intensive programs? Do you have a lot of background process in your activity monitor that are taxing the system? Most folks I have seen post here find their battery issues resolved after a replacement, not recurring every 3 months.

    I don't think you have a case.
    You can replace the logic board yourself if you are a DIY'er and save some money.

  • My MacBook Pro battery is empty and won't charge, but charger is fine

    My MacBook Pro battery is empty and won't charge. I did the PRAM reset when there was still some power left in the battery. The charger indicator light doesn't come on when I connect it to MacBook Pro, BUT it works just fine with my old white Mac book. This happened a few times before, and unplugging and plugging the adapter into the MacBook pro helped. Now nothing happens no matter how many times I reset the charger. Is there anything else I can do?

    More than likely you need a new battery.

    Reset the SMC > http://support.apple.com/kb/HT3964
    It's clear that the battery has got enough capacity to work correctly, so something happens with the MagSafe port or its charger. If you have another charger, try it, and if not, take the MacBook and the charger to an Apple Store or reseller. It's better to do this as we don't know if the problem is in the charger or in the MacBook Pro

  • Difference between Macbook Pro "13 and "15

    I was just wondering what other differnces are found in the Macbook Pro "13 and "15 Non retina other than the Screen size. Thanks

    Graphics capability.
    Besides the size, the 15" model has two GPUs, the one built into the regular Intel CPU and an extra one with way more oomph. Plus it has separate and dedicated VRAM just for the graphics, so the GPU and CPU don't do a battle royale for access to a shared memory. This really improves performance. You can also custom-order the widescreen display (essentially, half-a-Retina without the cost) and even the anti-glare option, essential for use outdoors. Plus many more configurable customization options.
    13" models just have the piddly integrated GPU and shared memory. Very graphics demanding apps fall flat on their face in this platform.
    Also, the 13" models have a single fan, vs. the two on the 15". So when used intensively, will run hotter by default. And the battery will last less since it is smaller: battery capacity is directly proportional to the volume.
    But some people still prefer the smaller size and somewhat lighter weight.

  • Macbook Pro Keyboard and Trackpad Not Working

    few days ago, my Macbook Pro keyboard and trackpad started to act very oddly.
    Basically, the keyboard doesn't work at all. I press down the keys, and all I get is that error message sound. The volume and display brightness keys seem to work, but almost all of the others just won't type anything. it-s like any key command or alt would stay pressed so when i click any key its trying to perform other function instead of just typing the letter. that-s probably the reason why the trackpad is also being very odd. When I first turn on the laptop, it seems to work as normal. I can click on an application, and it opens. But about one minute after the laptop first starts, it's like anywhere I click on the trackpad is a right-click. To open an application, I click like I normally would but instead of opening, a menu pops up as if I right-clicked. This happens in Finder and everywhere else that I've tested (for instance, I can't drag any Finder windows to different positions on the screen, because it acts as if I right-clicked instead of left-clicked), no matter whether I tap or click the trackpad.
    I have reset my permissions, but that didn't fix anything. I verified the hard drive and it said there were no problems. A big issue is that I can't do anything that requires me to type in my password, since I can't type anything. I tried to reset the PRAM, but I don't think that it even registered me pressing the Command-Option-P-R keys when I booted up, so i just removed the battery for a while, i am not sure that did anything at all.
    i tried to reinstall the os, i had mavericks and i installed a fresh mountain lion but the problem persists. i recently installed virtualbox and the keyboard seems to work right as long as i do not press any of the following keys command, alt, shift, etc.. if i press any of them same thing happens. i found that if i connect a usb keyboard everything works, but when i use the inbuilt keyboard the problem is back and a i have to connect disconnect the usb keyboard to be able to type or use the trackpad normally.
    any help would be appreciated.
    Thank you.
