My MacBook Pro is only 3 months old with 37 battery loadcycles. I calibrate my notebook monthly and the battery capacity stays the same. I have also tried resetting the SMC and nothing happened I do not have my laptop continuously charging, the most would probably 4 or 5 days straight. My current battery capacity is 91%. What should I do?
View 1 RepliesI have a MacbookPro mid 2009 and have some problems with my battery. This morning I noticed that the battery was empty through it was supposed to be in sleep mode during the night. My battery has 97 cycles and has 99% of its original capacity. What could be the cause of this problem ?
When calibrating the battery, is it better to do a quick drain with a dvd or cd burning or a slow drain with the brightness all the way down or does it not matter?

As such, I've disabled hibernation on my MBP.I am wondering about battery calibration, as you need to drain the battery down fully and have the MBP enter the hibernation state to properly calibrate the battery.

I plan to baby this thing, and I am always very conscious of battery life for all of my devices, so do any of you have any advice for how to best handle the first charge/discharge cycle?The machine almost fully charged out of the box. Should I run it down to zero and then fully charge it? Should I fully charge it first and then run it down?

View 4 Replies View RelatedWhen you see the low battery warning, save your work and close all applications. Keep your computer turned on until it goes to sleep.
After your computer goes to sleep, turn it off or allow it to sleep for five hours or longer.
Connect the power adapter and leave it connected until the battery is fully charged.
I just got my first Mac yesterday, 13" MacBook Pro. I LOVE IT! I've been trying to find out some info on the battery calibration that I can't find anywhere. I have tried Apple's website, Google and MRoogle before I made a new thread about it
View 1 Replies View RelatedOk, so I just did a battery calibration and once the battery got really low, it shut off, but didn't go to sleep like it has done before. It completely turned off; the battery light indicator is not indicating it is asleep. I've never seen it do this, has anyone else had this happen? I have a 2006 MacBook Pro, 2.33 C2D, non-unibody.

I love it love this thing!We did migration from our imac and everything came over. AmazingOne question about calibration. I charged it fully and let the power cord be in it for an extra 2 or so hours. I then used it unplugged until it basically shut off due to no power. Cant I just plug it in and let it charge all the way without letting it sit for 5 hours. Its not sleeping I dont think. It actually shut off suddenly as it was at zero percent. There is no power to it at all that I can tell. Will charging it now without leaving it unplugged for 5 hours ruin the calibration??

View 1 Replies View RelatedI've just calibrated my battery on my 2.4GHz MBP (let it run out until it slept, then woke it up, then used it till it shut down, then charged it) and it's stuck on "finishing charge". Additionally, the battery health has gone down to 23% from 37% since I have done this.
View 10 Replies View RelatedI was sick of the battery life I was getting on my 15" Macbook Pro 3,1 (early 2008 model), so I went to the apple store yesterday to get a new one. I was over 400 cycles, so I had to just buy it, they wouldn't replace it for me. I expected that, so no big deal. But I wanted to treat this battery right. I got home, charged it up to 100%, let it sit at that for a few hours, and then let it drain overnight and rest at empty for a few hours. This afternoon, I plugged it back in with the intention of letting it fully charge and thus complete my battery calibration, but at around 40% charged, the cat yanked the charger cable out from my laptop. And then a little bit later, my girlfriend did it again. So, has my time been wasted here? Battery calibration is such a pain in my rear. i hate it. I use my laptop often and expect it to be available to me whenever I need it, regardless of how many other computers i own. I really don't want to deal with it again in the near future. And I may not.

View 3 Replies View RelatedLast night I calibrated my battery. Let it fully charge for 2hrs, took it off the charger, turned up the screen brightness and keyboard backlight all the way, then proceeded to run the battery down watching videos and whatnot. It went to sleep and I went to bed to let it sit for 5 or more hours. Woke up, charged it up, turned it on and noticed that I went from 97% to 87% (coconut battery says 86%) and I only have 54 cycles. Should I go to the genius bar or something? Or try re-calibrating the battery? Did I do something wrong when I did it? Does it matter how long it takes to run down the battery after it's fully charged?
View 10 Replies View RelatedI just bought MBP 17 i5 model a couple days ago from a local apple store(Keystone Mall). and I calibrated my battery yesterday. The thing is I know MBP should sleep when the battery is really low(running off reserve) then when the battery drains out, MBP should do the "safesleep" thing where it stores the current state of the machine so that upon turning the machine back on by supplying the power to it or after charging, MBP returns to the stored state.
But, when i was calibrating my battery, I did get the low battery warning(reserve battery blah blah) but then it drained down to 0 then the screen flickered(literally made a flicking sound) and went dead. When I got up in the morning I plug the adapter on and turned the MBP on and MBP just freshly boots.. rather than restoring the previous state..................
calibrating my battery for the first time this morning. i just opened my macbook pro to see that the time left icon jumps every minute. it goes from 8:50 to 12:38 to 6:54 to 11:37 to 7:40! and now it went from 8:45 to 9:19! the percentage remaining is consistent and correct but the time left is way out of whack! sorry for the slang! now it went from 9:19 to 9:11 then 8:47. i have the screen at the lowest brightness, no backlit keyboard, nothing else running except firefox. i wasnt aware that i was supposed to calibrate my battery and its been about 3 months since i bought this. now its at 8:37 now 8:18. this is quite
View 5 Replies View RelatedI have a 30 month old MacBook Pro (the SantaRosa line from June 2007)... And was still using the original battery up until 3 days ago. Its capacity suddenly dropped from 83% down to 45%, so I took it to an Apple store, they did a diagnostic, and without question told me the battery was defective, and just gave me a brand new battery with only 1 loadcycle on it. So today I decided to calibrate it, had it charged up, unpulgged it and let it run until it was 'supposed' to go to sleep... It had 0% left on it, the screen shut off, and the sleep light was just starting to dim, when I heard the hard drive go . (As if one pushed and held the power button, aka hard shutdown).
It seems it didn't have enough reserve capacity to let it go to sleep, so instead of waiting the 5 hours (as it wasn't sleeping, and pressing the button on the battery showed no lights at all), I decided to plug it in right away. Would it be a good idea to calibrate again, or simply wait a month or so and do it again then?
When I turned the computer back on, it didn't even resume at my desktop, so not only did it not get to sleep properly, it didn't even have a chance to write the memory to the hard drive, and now the actual battery capacity in Coconut battery is showing up 95%, 5253mAh
Just curious, as 30 months ago when I first got my original one, it calibrated properly and didn't completely die when it got to reserve capacity...
I just got a Mac Pro Octo 2.93. It has a 4870 card and 4 1tb drives. I also have a Sonnet E4P e-SATA card installed. Would a 780 Watt 1200 VA surge suppressor be enough?
The other question is about waking the computer up. My old G5 Quad (7800 GT card, E4P card, 2 500gb drives and 8gb RAM) would wake up and while the afore mentioned surge suppressor would beep, the room electrical breaker wouldn't be tripped. Using that same suppressor for the Mac Pro results in the breaker being tripped when the computer wakes up. Would getting a bigger suppressor help with this? In other words, does a unit with a bigger battery capacity allow the battery to take the extra load when the computer wakes up preventing the breaker from tripping?
I have a 2008 Macbook and when the power is plugged in, the light is green, however my battery will not charge, and it even says at the top "battery is not charging" If I remove the power cord from the computer it will still run off the remaining % of the battery, but If I reconnect the cord it lights up green and I never see the amber charging color. I traded out my battery as well as a different cord and still the same results. My battery will charge up on a friends macbook, but not on my own. I want to take it to the apple store but I'm at school and there is no store near me.
View 1 Replies View RelatedMy AppleCare expires on Monday September 6th, and I am wondering if my 87% capacity at 51 battery cycles suggests I should visit an Apple Store this weekend? The closest store is around 25 miles away, so if I would be wasting my time, I would rather not take the trip. My concern is mostly based on my warranty ending. This is a 2009 13" MBP.
View 24 Replies View RelatedI used an app on my MBP called Coconut battery. it said that my current battery capacity was 94% of what it was since I bought it. I assumed that means those 6% are never coming back and I should start using it more responsibly to make it last longer. I read a lot of forums on how to use your notebook effectively, when to plug it in, how much I should let it discharge etc. After 2 weeks of my new habits, I checked my battery life again and now it says 96%. Is it even possible for it to go back up?
View 5 Replies View RelatedI have MacBook Pro about 17 months old (bought new Summer 2008). According to Coconut Battery, my current battery capacity is 96% after 185 cycles (see below). This was taken just after I re-calibrated the battery last night. I usually work the laptop from the battery ... I rarely leave the laptop plugged in unless charging, and when fully charged I always unplug and run the battery down before plugging in again. So, is 96% battery capacity good or bad for a 17 month old MacBook with 185 charge cycles? Is the way I'm charging ok, or is it better to have the MacBook plugged in continuously and have less charge cycles (would this give me a better battery health %)?

Got a question about the battery in my wife's white Macbook. I just downloaded (and ran for the first time) Coconut Battery and it reports the following info:
Current Battery Charge: 5281 mAh
Maximum Battery Charge: 5281 mAh
Current Battery Capacity: 5281 mAh
Original Battery Capactiy: 5020 mAh
Battery-LoadCycles: 60
Age of your Mac: 8 months
Now, I'm no rocket scientist, and I'm definitely not complaining, but how in the world does my battery have More capacity now than it did when it was new? Is this an error in Coconut? System Profiler reports the same capacity and my research online seems to concur that 5020 mAh was the original capacity.
I've got a 4 month old Macbook Aluminum 2.4 ghz. I was getting great battery life for the first couple of months. But I'm now getting 3:10 with screen half light, and wifi on, bt off, doing a bit of downloading, etc. I've recalibrated the battery a number of times. According to activity monitor my cpu is hovering under 10% when I'm doing my battery test. This is at least 2 hours less than I was originally getting. Coconut Battery tells me that the original capacity was 4100, but its currently at 4052. Battery load-cycles are at 97 and it says the Mac is 5 months old. Should I take it in to the Apple store under AppleCare?

View 3 Replies View RelatedI get ready for the next disappointment tomorrow (maybe no MBP update) and looking out for a MBP at eBay. I've found a good one (August 2009) 2.53 GHz, 4 GB RAM, 500GB HDD etc. for round about 900� (1.200$) (in Germany we pay 1533� for this model so round about 2088$). The guy sent me a screenshot of the battery capacity which is 87% (4762mAh) after 56 loadcycles. Is that acceptable? IMO it's a bit too low - what do you think? Maybe I'm going to buy a AppleCare Protection Plan afterwards ... would the battery be covered?
