MacBook Pro :: Shuts Down After Sleep When 2 Percent Battery Left
Feb 8, 2012
I have my mbp just 3 weeks old and I tried to calibrate the battery just few hrs ago. I continuously used my mbp until the battery level reached to 2% (the warning message showed when it was 6%). Just then I had to receive a phone call. When I was busy talking, I noticed that the mbp has gone to sleep mode but when I returned (2-3 mins later), I found it shut down. Well, I think it should have remained to sleep mode but it didn't.
Then after an hour I connected the power cord and switched on and noticed a progress bar which I saw for the first time. I have been charging it for 40-50 mins, now. Also the health of my battery keeps fluctuating between 95-100 %. istat shows this. Is this normal? So what I want to know is, Is this normal for mbp to shut down when the battery reach that low? OR there is some problem in my MBP?

My Macbook Pro keeps shutting down before I reach zero percent battery and often when the battery still has 25% left. I am wondering if this is a software issue that may be fixed or if there is something incompatible with my hardware. I am running 10.6.4 with a 2.16 GHz Intel Core Duo, 2 GB 667 MHz DDR2 SDRAM memory bought in April of 2007. My mac was originally running Tiger, but a few months ago I updated to Snow Leopard.
After all is said and done, and heavy Macbook Air use, there is only one thing still bugging me. Its not the slightly uneven lighting, not the 3 hours charge nor the 3:30 battery life I get constantly, nor the 6200 RPM fan. When I charge to 100% and let it sleep for 12 hours, I lose about 20% of the charge. Yesterday I was at around 25% and when I opened it this evening, 24hrs later, there was nothing left. If I leave the macbook air closed, I think that the battery would reach 0% after 3 days. This is not normal and some kind of leak.
I would like to my macbook pro to be turned off at 5% Battery power, as it doesn't turn of correctly at 0%. I'm having this issue for some years now, and want to get rid of it. Which plist needs to be changed for this? Or is there a Terminal-Command that's providing this? I don't want to buy a new battery yet, cause the one I have is quite fine still. I already reset the SMC and the Parameters. Is the battery status relevant, when resetting the SMC?†Here's what has been going on so far: [URL]

Is it strange that my MacBook now just shuts down when it runs out of battery instead of just going into sleep mode? It's about two weeks old now. It used to go into sleep mode, but now it just shuts down once the battery is down. Also, I had the most wonderful experience with Apple. My first macbook (three weeks ago) had a small chip on the screen. When I finally noticed it, I thought it was a large piece of dust so it wasn't too terrible. I tried to exchange it at the local store where I purchased it, but it had already been four days and I had cut out the UPC for the printer and ipod rebate the day before and sent it out. So they recommended that I go see a mac genius and see if I can get the screen replaced because I could no longer exchange it or return it (risk losing my rebates).
So, a bit upset that I was too prompt about getting the rebates in, I scheduled an appointment with a genius. When I spoke to him, he just went to the back and got the manager. The manager said instead fixing the screen, he'd liked to give me a new macbook and instant reimbursement for the ipod and printer! (the rebates I sent in will be rejected since the mac has been returned). The new macbook I noticed has a much louder superdrive seems to be working hard every time the computer wakes up and when I open it, but that definitely beats a chip on the screen. But now it doesn't go to sleep after the battery gets low, but instead shuts off.
Whenever my battery gets drained, my MacBook Pro turns off as if the battery was pulled out, I lose all my work when this happens.This started after I installed Snow Leopard, before, it would just go to sleep and my work is safe.
I calibrated my battery for the first time since Dec. When I plugged it in this morning, it took 3 hours to charge all the way, and now it's stuck on 99% full, 0:00 till completely charged, and I'm getting an error when I click on the battery in the menu bar that says "Service Battery". When I click on the error, it tells me that it may not be functioning properly and to take it to an authorized apple service retailer. Before I waste 2 hours by going to the Apple store and back, has anyone else had this problem, and is there a way to fix it without having it looked at?
The battery on my MBP (2007 2.33 Core 2 Duo) has started to die, just like the three others that came before it. It seems like it's only been a year or so since I got a new battery. Yesterday, I was using it unplugged and the computer shut off when the battery was around 58%. I have never seen a battery shut off that early. The worst I had seen before that was a previous battery that would die around 35%.
A couple questions:
1. Is there something I am doing that is causing my batteries to keep dying so quickly? An Apple Genius told me that keeping the computer plugged in all the time can burn out the battery. I don't really want to bother putting the computer through unnecessary charge cycles to keep up the battery life.
2. Is there any way to recoup some of the lost battery life of my current battery, or is it just dead?
3. In replacing the battery, should I buy another Apple battery from the website, or are there better quality 3rd party MBP batteries?
4. On a side bar, I am thinking about purchasing a new MBP, but I am worried that the battery will have the same problem, and it will be much more of a hassle to fix because everything is internal now. I hate having to hand my computer over to Apple Care for a whole day and be without it.
So I bought a macbook pro 13" about a month ago. I've been running coconut battery tests on it and the battery health is only at 89%. This is super upsetting to me. I went to the apple store and they ran their diagnostic test only to tell me that my battery is within specification, so they wouldn't replace it. The health they calculated was 91%.
What should I do? This seems unfair to me. Coconut battery stats: Battery capacity: 5141 mAh Original battery capacity: 5770 mAh Battery load cycles: 27 Age of your mac: 4 months
I've had my Macbook Pro for just over 2 years and recently bought one of the 2010 models. I'm about to sell my old one but when I downloaded Coconut Battery, I saw that my battery holds a lot less charge than it did when it was new: Have I been doing something wrong or is it just low because the laptop is 2 years old? If it's something I've been doing, I don't want to make the same mistake with my new one.
I usually keep my mac connected to AC power and probably once a week I try to drain the battery. It only has 28 cycles. I bought it last year on november and today when I removed the ac power, a little while after I realized that the battery health went from 88% to 77%! What can I do? I am doing everything that mac says to keep a healthy battery!
I just bought my macbook pro not long ago. around 2months? And my battery is going down really quick. 1% every 3 mins and I only have firefox on and my backlight is turn off. My brightness is turn on to the middle. I was looking at my friends macbook. Doesn't seem to be going down so quickly.

I bought a new battery for my sisters new used MacBook Pro. The instructions with the new battery was not to charge the new battery until it's was down to 2%. And, how many hours should she expect the battery to last until it needs to be charged? This is with normal web surfing with some streaming. The MacBook Pro is a 2.3 GHz Intel Core 2 Duo with a 15" screen form @ 2008.
I set the MBP to sleep in 10 min through the Energy Saver pref with the option to sleep the hdds. When it's about to sleep the screen dims, then turns black, then the sleep light comes on but does not blink no matter how long I leave it. The blinking only happens when I close the lid or when I select the Sleep option under the Apple logo. Is that normal behavior?
I'm having a strange issue with my MBP 1, 1. It's recently picked up a new habit that I find to be rather annoying. When the battery gets down to between 5 and 10%, the laptop will just shut off. No hibernation, no sleep, just a hard shutoff. The battery seems to be in good health; although it does have a high cycle count, I still get around 2 hours of usage out of a charge. I would think that a calibration would solve the problem, but with the hard shutdown, would that even be possible?
So when I bought this the guy said that Apple installed a new battery on it recently. I believe him because when I downloaded the iStat Pro widget it said only 2 or 3 cycles which is because I calibrated the battery. But I just finished charging and the light is green. But it says the charge is only at 97%. I don't see why it should be like this. Also when it's not plugged in the battery only lasts maybe 3 and half hours from just surfing on the internet. But I thought it was supposed to last like 6?(I'm thinking that since mine is an older model, that could be it.
Ok so to start off, my Macbook Pro is around 3 years old. With my original battery having been through 350+ cycles, I had to buy a replacement. So I did some research and found that the Fastmac battery was my best bet for a long-lasting, reliable battery. I would say that Ive had the Fastmac battery for a bout 6-7 months without any problems whatsoever. However, recently Ive been noticing the drastic change in battery life. I installed Coconut Battery yesterday and discovered that my current battery capacity is 2266mAh with the original capacity being 5800mAh and 213 cycles. I also should note that the battery drains 1% a minute with no programs running (besides the Activity Monitor, which showed no strange behavior). Now luckily for me, My Fastmac battery is under a 1 year warranty, however I just wanna verify that it is a fault with my battery and not anything on my Macbook's side causing the battery to drain so quick. The last thing I want is to receive my replacement and then have to go through the same process 6 months later.
Also here is the Battery Information from the System Profiler. Battery Information: Battery Installed:Yes First low level warning:No Full Charge Capacity (mAh):2266 Remaining Capacity (mAh):1414 Amperage (mA):-1449 Voltage (mV):11421 Cycle Count:213
I noticed that my battery cycle (according to istat) switches over at 15%. So as son as it switches over to the next cycle I plug in the adapter to make the battery run a cycle from 100%-0.(I know the cycle in 100%) But it still switches over at 15%, that means that the battery ran only 85% of its capacity. How can that be? Is it possible to reset (delete) battery cycle data?
I have a 5-year-old PowerBook G4. I remember I changed the battery about a year or two ago, because when I used to take it to classes in college, and use it unplugged, my laptop would shut off in less than an hour (more like ~30 min) when it reaches ~30%. After I got a new battery, it went back to normal, and lasted much longer. In the past couple of days, I noticed that within about 5-10 minutes of using my PB unplugged, battery goes from 100% --> ~85%, and then all of a sudden shuts down.
When I plug it back in to a power supply, and it starts back up, it starts recharging from 0%... this seems a little extreme. I haven't noticed this problem because I almost have it plugged in these days, as I usually use it at home or at work where I have a power supply available, and I use it for a few hour period at a time. Does this seem purely like a battery problem?! (ie. it's just time for a new battery...)
So I just got my first MBP, and I have calibrated my battery. Both iStat and Coconut Battery report my battery health is 98%. Do you think this is reason for concern, considering the MBP is supposed to be new? What is your new MBPs battery health?
My battery needed replacing for a couple of months before i dropped it from about knee level onto a sidewalk. After the drop I got the not charging icon. I thought maybe the battery had just finally died. so I did not panic about the no charge. The laptop works fine when plugged in to power with the old battery on or no battery at all. Not at all when unplugged.
When I put the brand new battery on the lap top, the computer shuts down halfway through boot up. I tried holding the power button down through boot up reset, as well as removing all power (plug and battery) and holding down the power button for 10 seconds reset.
