Macbook Battery Calibration Questions

Greetings!
I just bought a MacBook today (the mid-range white model) but I am a complete tyro in the Apple world. I have a few questions with respect to the calibration process. The manual is lucid with respect to everything except for three issues:
1. The instructions make no mention of whether or not I can turn on my MacBook and use it during the first charge cycle (that is, the charging cycle before the two hour normal use stage).
2. The instructions do not indicate whether or not I have to wait until the battery is completely dead during the "die-down" stage (the supposed five hour sleep stage) before I plug in the charger and fully charge the battery again. Is it all right to plug in the power adapter after the computer has slept for five hours while the computer is still in sleep mode?
3. If for some reason I screwed up my first calibration (perhaps due to mishandling the process in (1) or (2) above), is it detrimental to immediately run another calibration process (i.e. treat the second "power up" cycle as step one of the calibration process)?
The reason why I raise these issues is because I am currently calibrating my MacBook as I speak. I plugged my adapter into the computer, turned it on, and ran programs (iTunes, CD ripping, Wifi) while the initial charge cycle was running. I have let the computer fully charge and have left it fully charged for a little over two hours. I am about to disconnect it and move to the "die-down" stage (that is, I will let it die down into sleep mode). I am concerned about whether or not I have faulted at any point in the calibration process. Any help regarding my questions would be much appreciated. Thank you for your time and consideration.

And yes, it is ok the plug the adaptor while the computer is in sleep mode. The battery will charge as normal.
No, I think this is wrong. You need to let it sleep without the power adapter. This causes the battery to deplete most of the remaining reserve charge. If you look in the manual on pages 23-24, steps 4-6 are critical. Basically it says to drain your battery till it goes to sleep (step 4). Then let it sleep for 5 hours (step 5). Then plug in the ac adapter and leave it in till it is fully charged (step 6).
So do not plug in the AC adapter until it has either been off for 5 hours or in sleep mode for 5 hours.
Personally I don't see how you can shut it off instead of sleep mode for the 5 hours, as once it goes to sleep mode, from low battery, you cannot wake it to turn it off unless you plug in the AC and that defeats the whole purpose...

  • Mid 2010 15" i5 Battery Calibration Questions

    Hi, I have a mid 2010 15" MacBook Pro 2.4GHz i5.
    Question 1: I didn't calibrate my battery when I first got my MacBook Pro (it didn't say in the manual that I had to). I've had it for about a month and am doing a calibration today, is that okay? I hope I haven't damaged my battery? The calibration is only to help the battery meter provide an accurate reading of how much life it has remaining, right?
    Question 2: After reading Apple's calibration guide, I decided to set the MacBook Pro to never go to sleep (in Energy Saver System Preference) and leave it on overnight so it would run out of power and go to sleep, then I'd leave it in that state for at least 5 hours before charging it. When I woke up, the light on the front wasn't illuminated. It usually pulsates when in Sleep. Expectedly, it wouldn't wake when pressing buttons on the keyboard. So, what's happened? Is this Safe Sleep? I didn't see any "Your Mac is on reserve battery and will shut down" dialogues or anything similar, as I was asleep! I've left it in this state while I'm at work and will charge it this afternoon. Was my described method okay for calibration or should I have done something different?
    Question 3: Does it matter how quickly you drain your battery when doing a calibration? i.e is it okay to drain it quickly (by running HD video, Photo Booth with effects etc) or slowly (by leaving it idle or running light apps)?
    Thanks.

    Fresh J:
    A1. You're fine calibrating the battery now. You might have gotten more accurate readings during the first month if you'd done it sooner, but no harm has been done.
    A2. Your machine has NOT shut down; it has done exactly what it was supposed to do. When the power became critically low, it first wrote the contents of RAM to the hard drive, then went to sleep. When the battery was completely drained some time later, the MBP went into hibernation and the slepp light stopped pulsing and turned off. In that state the machine was using no power at all, but the contents of your RAM were still saved. Once the AC adapter was connected, a press of the power button would cause those contents to be reloaded, and the machine would pick up again exactly where you left off. It is not necessary to wait for the battery to be fully charged before using the machine on AC power, but do leave the AC adapter connected for at least two hours after the battery is fully charged. Nothing that you say you've done was wrong, and nothing that you say has happened was wrong.
    A3. No, it does not matter.

  • PB 15" aluminum double-layer SD battery calibration question

    The instructions for calibrating a battery on the double-layer SD Aluminum 15" powerbook (visible here: http://support.apple.com/kb/HT1490) say to fully charge the battery, let it rest charged for at least two hours, then use the computer to discharge the battery, and let it rest fully discharged for at least five hours)
    What is not clear is whether or not it's OK, during the "rest five hours discharged" phase, to remove the fully discharged battery from the computer, put in a different battery, and continue using the computer. In other words, does the discharged battery need to remain in the computer during the five hour rest period? I'm completely unclear as to what (if anything) is active in the computer during sleep, and whether or not the battery processor and the computer are talking to each other at all during this period.

    I always assumed the "rest five hours discharged" phase is actually to completely drain any residual power in the battery, to trigger some sort of reset within it.
    (But it's not an easy procedure to follow is it? Clearly something significant was changed for this very last set of PowerBook models, and now four years later some of us seem to be having lots of power-related, battery-charging, problems. I still think that calibration should have been done in conjunction with the OS managing it, and suggesting it be done on a suitable, scheduled basis.)

  • Black MacBook battery charger question.

    Can I use the charger from a 2009 MacBook Pro on a 2006 Black MacBook Pro?  I'm having trouble charging the battery on the MacBook and now think it might be the charger (I've already replaced the battery, reset the SMC, and run he battery update).  The specs on the chargers themselves are very nearly, but not quite identical.

    but my battery is still working fine
    I'll be you anything it's not. With that many cycles it's not uncommon for weird things to start happening regardless of how well it performs. I would look into getting a new battery as well.
    Have you reset the SMC?

  • Battery calibrating question

    Hi,
    Today, I wanted to calibrate the battery in my new MBP. I just wanted to know if restarting the MBP would ''affect'' the calibration process. Because I was installing some apps and I didn't remember I was calibrating my battery so I accepted to restart.
    So now I would like to know if I need to restart the whole process all over ? Let's admit it, the calibrating process is quite long.

    As long as you didn't connect the power adaptor at the time I suspect the calibration will proceed normally, slitcher.

  • KB article 1490 on battery calibration needs work

    http://support.apple.com/kb/HT1490 says:
    "Disconnect the power adapter while the computer still on and start running the computer off battery power. You may use your computer during this time."
    Does “running” mean something different than “use”? Does this instruction mean the computer should not be allowed to sleep?
    [And fix the typo: "still on" should be "still is on".]

    Assuming that, then -- do both terms mean the computer 1) can or 2) cannot be put to sleep?
    The context here is the instructions are for "Apple Portables: Calibrating your computer's battery for best performance". The instruction in question is #3 for
    PowerBook G4 (15-inch Double-Layer SD), MacBook (all models), MacBook Pro (all models), MacBook Pro (17-inch) (all models) and MacBook Air
    The battery calibration for the PowerBook G4 (15-inch Double-Layer SD) and any model of MacBook or MacBook Pro has been updated because of a new battery released with this computer. With these computers, follow these steps to calibrate your battery:
    1. Plug in the power adapter and fully charge your PowerBook's battery until the light ring or LED on the power adapter plug changes to green and the onscreen meter in the menu bar indicates that the battery is fully charged.
    2. Allow the battery to rest in the fully charged state for at least two hours. You may use your computer during this time as long as the adapter is plugged in.
    3. Disconnect the power adapter while the computer still on and start running the computer off battery power. You may use your computer during this time. When your battery gets low, the low battery warning dialog appears on the screen.
    4. At this point, save your work.  Continue to use your computer; when the battery gets very low, the computer will automatically go to sleep.
    5. Turn off the computer or allow it to sleep for five hours or more.
    6. Connect the power adapter and leave it connected until the battery is fully charged again.
    Does the calibration process require, in step 3, that the computer be kept awake? It seems likely, given step 4, that step 3 allows the computer to be in either the wake state or sleep state.
    My interest is in clarifying whether the calibration process requires that battery draw-down be relatively quick (as when the computer is awake) or does speed not matter (i.e., the computer can be either awake or asleep).

  • Another calibration question

    hey all,
    when calibrating my MacBook battery, once the battery is fully charged and i've let it set for at least two hours with the adapter plugged in, i unplug it and let the battery start to drain. Question: At this point in the process, does it disrupt the calibration process if i shut it down or let it go to sleep, so long as i don't plug it back into the power adapter? sometimes, while in the "discharging phase" of the process, i have no choice but to take my computer with me somewhere, which inevitably means putting it to sleep or shutting it down. i don't think it would interupt the calibration process but i want to be sure. thanx very much!
    David

    It is ok to put your MB in to sleep in this step of the process. See your MacBook User's Guide on pade 24, step #3.

  • Can MacBook battery life be as longer as MacBookPro

    Hello
    I had watched the new add about MacBookPro' s battery life and thought if I could use my MacBook up to 8 hours and if I could charge my MacBook up to 1000 times, which is also extremely a big number for charging cycles, it would be really great for my education. During some long meetings or presentations (like Apple Keynotes) I need some charging equipment and sometimes the electrical sysytem of the meeting rooms don't let me to recharge my MacBooks battery. So my question is "Can a kind of powerfull battery, like MacBookPro's, seperately sold for also other Apple remote products?"

    Nope not available for anything except the 17" MBP.
    If you want to maximize your battery life turn off bluetooth, IR in the security prefs unless you are using a remote device, wifi, and turn down your brightness a bit. Also make sure you are calibrating your battery to keep it in shape every 2-3 months. by charging to full and letting it charge for two more hours, letting it drain all the way, and then letting it sit discharged for at least 5 hours. Last, charge it fully.

  • Macbook Battery Problem

    Hi all, this is my first post, but something weird happened to my macbook that I have to share with you.
    Ok, my Macbook Core Duo 2.0GHz (1st generation) have had no problem during its first and half year. Then I left the notebook sitting at home for one month as I was away on business. Came back, the machine won't start, used AC adaptor and showed the battery not charging, "x" and everything. My warranty expired, so I bought a new battery. Once I got that, it worked fine for almost 7 months.
    Another business trip left my macbook for 1 month, I came back, the battery is dead again!!! So I went to apple support and bought another new battery. This time I installed it at home, and it doesn't charge what-so-ever. I tried everything from SMU reset, PMU reset, P-RAM reset. NOTHING WORKED.
    So I took a friend's macbook battery to try, and it worked! I can charge that battery with my macbook, and my battery won't charge on his macbook. So scientifically I thought its the battery defect. I went to Apple Care and they say they will replace it for me, but think that it should be my macbook's problem. Must be the Logic Board, I explained why I disagree, and that the battery came with only one LED blinking when I got home to charge, the current was already too low to charge.
    Anyways, I was able to buy a second-hand battery really cheap but with limited life-span and use it until my replacement battery returns. Everything seem fine and I can charge it up to 100% although it will only last me 50-mins, still not bad, right?
    I was reluctant to completely drain this battery now since I am afraid it will drop to zero and won't recharge like the other ones.
    I am using Boot Camp, and Vista as well as OS X. Suddenly today, two days after I bought the 2nd hand battery, I was using Vista to show my friend the battery problem is fixed. But suddenly out of nowhere the battery dropped from 95% charged to 0% in seconds. It shuts down automatically, and the battery was flashing one LED indicating it's dying.
    I started back in Mac OS X and found the charger able to recharge, but it fixed at 0% for 20 minutes. I thought I am screwed and went out for a smoke. I came back to see the battery charging back to 5% and then slowly to 10%, and 20%, suddenly it went back to 85% in seconds, and then 100%. I try to unplug it and it seemed fine. I left it on without the adapter for 20 minutes, the battery drain normally, to 70% (it's fine considering the battery was 2nd hand) My friend thought I should try to switch back to Vista to see if the same thing will occur. So I did, and before the Vista screen came up, the macbook blacked out. I checked the battery indicator and it's flashing one LED again!!!
    So I switched back to Mac side and re-do the charging, this time it took longer to get back to +90%, I thought this is normal, 'cause I did use the battery longer on the Mac side before switching to Vista for the test.
    I thought to myself, why Vista drained my battery, and then I remember the first battery that died on me was about the time I switched the PC side to Vista. Prior to that, the PC side was using XP. The second time it died it was in Vista as well. I also remember I wanted to reduce the size of my PC partition, so I trimmed off unnecessary features like hibernation by (Powercfg -h off). It saved 2G in size but it may be causing some problem to the charging circuit for the Mac-hardware??? Don't know for sure.
    So I erased my Vista partition, and re-installed XP. Since then I tried both sides without adaptor, usually for 10-minutes or less, and no sudden dropped to 0% occurred since.
    Everything else is working fine with my macbook, except the power features. Right now at least I can charge the battery, but I am always worried about when or IF the battery will dropped off and kill itself.
    I am waiting for the replacement battery to return from APPLE, and hopefully when it returns, my Macbook will be able to recognize the DEFAULT low-charge of a new battery. I'm still not sure if my macbook is defective, and if it did killed the first battery replacement they gave me a few days ago. If it did kill a decent battery, will it kill this new replacement as well??
    I know for a fact that the reason why the machine won't charge the battery is because the current of the battery has become too low for the machine to be able to charge it. If the current becomes lower, the "X" will occur suggesting that the machine doesn't even recognize it's a battery. But what I want to know is what caused the battery to drop to such a low current if I turned off the macbook during storage.
    Sorry for the length of this post, but I have to be clear on all the details if I want help, I suppose. Right now my question is (1) Why is this occuring?? (2) Am I right in assuming that by removing Vista with XP, the problem will not repeat?? (3) Is it likely for any new or 2nd hand functioning battery to drop to the state of the other battery any time soon?? (4) Am I doing proper care for my Macbook, and what should I do in the future to avoid the same problem from occuring??

    gpotts,
    Thanks again, here's my battery profile: (keep in mind this is the 2nd hand battery I am profiling) BTW, something happened when I was doing this message, I left the notebook on for about 20 minutes, it dropped from +90% to 48%, macbook prompted me that the battery is running low. I plugged the adaptor and it went back to +95% within minutes...
    Good thing is, I haven't seen the sudden drop to 0% ever since I removed Vista, and also I am able to charge my battery everytime I try now, no more "NOT CHARGING" or "X" indication.
    Any clues??? Thanks in advance.

  • Do I need to run my Macbook battery flat?

    Will I prolong the life of my Macbook battery if I occasionally allow it to run flat?

    Running it flat doesn't do anything special, but as Mort mentions Apple recommends that you calibrate your battery every few months as shown HERE.
    Calibrating your battery really means calibrating the battery meter. It just resets the meter so that it gives a better estimate of the charge remaining.

  • Kernel panic after battery calibration

    My aluminium macbook was working nice until I did a battery calibration. Now all the applications are crashing: Safari, itunes, skype... Safari always crashes when I right click on a link and after some minutes the all system just crashed: kernel panic. How can I fix this. Is it a software issue or a hardware one? Does the kernel panic has something to do with the kernel panic?
    Thanks for your help

    Kernal panics are usually caused by hardware.

  • Q on battery calibration after reading KBs

    I have a late model unibody Macbook Pro 17" with the 1000 cycle battery; and I've read the Apple information regarding battery calibration, (along with http://discussions.apple.com/thread.jspa?threadID=1764220), as well as comments by Mac users,
    The confusing part to me is that in the article I sited below, it states:
    +Failure to do so for a long period of time can result in the microchip "fuel gauge" in the battery losing the ability to accurately determine the remaining charge, and it will report that there is more charge in the battery than is actually present. As a result, the computer will not initiate Safe Sleep at the proper time, and instead undergo a hard shut down, one of the main causes of hard drive directory damage. Once the battery is in the state resulting from a failure to calibrate, it is not possible to calibrate the battery, and it will need to be replaced.+
    First of all, this sounds like if you fail to calibrate frequently enough, then if you do calibrate, you ruin the battery and it has to be replaced. Is that correct?
    If it is correct, then it seems fantastically irresponsible to tell people that recalibration really isn't necessary if you use your battery regularly, because if the "fuel gauge" gets off, your screwed.
    So, if I am using my UMBP in the on-the-train scenario Apple states as ideal (which sounds like the first hour of the day w/o the charger, then on the charger), calibrate or no, and every one month or every three?
    Also, how can running the battery to 0% be bad for it, but calibration (running it to 0% every once in a while) not be bad for it?
    And isn't it nerve wracking to calibrate and not really know if the battery will survive the calibration if you forgot to do it for a while? That is what the quote above implies.
    Just as little confused is all.

    If you don't use the battery now and then and re-calibrate every couple of months then you won't get the best performance and life span from it. It's unlikely a single re-calibration would render it dead but that's not impossible if it's not been looked after.
    Re-calibration does not run the battery down to 0% simply below 5% - you're taking it from a state of maximum charge to minimum charge and back again - rather like a bungie rope.
    It's not going to die if you forget and don't re-calibrate for three months, but if you never re-calibrate for years it's not the best use of the battery.

  • How fast does a macbook battery usualy drain?

    I'm just curious how fast is typical for a macbook battery to drain each time you use it. I got a replacement batter b/c my old one was a dud. This one has drained 10% (100% to 90%) in about 35-40 minutes (constant use). I'm not saying that's abnormal, I'm just curious what normal is.
    Gracias!
    P.S. Screen is turned on medium light and bluetooth is off (however, wireless is on).

    That sounds good. If your battery drains like that you could get 4 or 5 Hours out of it. If you take good care of it you should have no problems. 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. Have you calibrated your batteryyet? You should calibrate every two months or so to keep the battery fully functioning. If you use your MacBook infrequently, it’s best to re-calibrate the battery at least once a month.

  • Keeping macbook battery plugged in

    so you guys leave your macbook battery plugged in all the times(i.e. even when you go to sleep the light on the magsafe adapted is still green?) or do you unplug it when you go to sleep. and when you keep it plugged in do you remove the battery? im using my macbook at home, so its plugged it all the time to reduce battery charge cycles. but, i noticed that the battery still drains when the macbook battery is plugged in. the day before it was at 100%, then i unplugged it when i went to sleep, yesterday it was at 99%, did the same thing, and today its at 98%. i know that anything above a 95(?)% charged will not get the battery charged, so following this patter, my battery will prolly reach 95% 5 days later or so, and this will get the battery to start charging. my question is if i keep charging the battery at 95%-100%, will it decrease the battery life? and after 20 times of 95%-100% will it accumulate 1 charge cycle? if so, do i decrease the battery to 50% charge and then store it until i need to use the battery, so i doesnt keep on going through the above mentioned cycle.

    This answers some of your questions.
    http://www.apple.com/batteries/notebooks.html
    All batteries have a self discharge rate even if they aren't being used. This accounts for the drop you see. I have mine plugged in 24/7 most of the time. I calibrate it every few months and once in a while I just run on batterys to let the electrons flow. Then when it gets below 90 % I let it charge. Short cycle charges are not bad for it. Most of the data says this is better than running your battery flat everytime you use it.

  • GS70 - Battery Calibration utility does not work (any longer)

    Hi folks
    Just got myself a brand new GS70 Stealth notebook. I got the pre-installed battery calibration utility to run OK once, but a few days laters it just quickly flashes 2 windows one after the other and is gone / crashed.
    Of course it might be something I did (upgraded BIOS, drivers, installed some apps), but I still need to find out what, otherwise it might happen again even after I reset to factory settings.
    I scanned all 33 threads of this forum found with the search "battery calibration", and found only one which describes something similar:
      https://forum-en.msi.com/index.php?topic=165389.0;nowap
    However the symptoms are not the same (I have Windows 8 and my other utilities KLM & SCM are working fine), and that thread is too old anyway. So a couple of questions to the community:
    1) does anybody experience the same failed start issue, with GS70 or other?
    2) can anybody advise on how to debug the battery calibration utility to try and find out where it crashed? (found no logfile)
    (note: I also tried to upgrade .NET to 4.5.1 as it seems to be used, no change)
    I will eventually contact MSI about this, but I thought that I would ask around first. Thanks for any help...

    Okay, just found the answer by myself: The battery calibration utility depends on a service "Micro Star SCM" (MSIService.exe), which I had disabled.
    Setting the service start mode to "manual" was enough to solve the problem, the utility starts again.
    Hope this can help someone else.
