OS X :: Recharge The Battery Till The Battery Meter Hits Red An Counts 1 Cycle?
Apr 26, 2010i have a 13" mbp with 130 cycles an i use it extensively.its been about 6 months since i bought it and i noticed tht apple will cover my battery in warranty fr one year only if it has less than 300 cycles on it.
my problem is tht i typically use my laptop fr no longer than 4 hours at a time. which means i recharge the battery jus before the battery meter hits red an counts 1 cycle as complete.thts why i got less number of cycles on the battery
cn i continue doing this without any adverse effects to my battery and its life ??
Hardware :: Macbook Battery Won't Recharge?
Sep 4, 2009My Macbook won't recharge. I drained the battery and then accidentally turned it off. I know this was the wrong thing to do since it wasn't shut down properly. Now it won't recharge and I can't get it to start up.

Jan 1, 2009I was wondering if doing a full charge and then a discharge is a good thing when a new mac or new battery is bought? Also should it just be a simple charge and discharge or does it have to be a full calibration? Also what is the best method in maintaining a healthy battery? Should I cycle at least once a week and do a calibration every few months? Or should one cycle per month be fine? Also is it alright if the battery is fully charged and I have the plug-adaptor plugged in to my MacBook Pro while using it? Finally, is it true that over night the plug or when not in use and not charging the plug should be outside of the MacBook Pro?

Aug 5, 2010When 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.

Sep 11, 2010Ok, 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.

Oct 12, 2010Well I just scored a 15 inch 2.4 from Bestbuy for 10% off. SOmebody just returned it having never even used it, but they had to discount it because it was opened. 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??

Jul 19, 2009I 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.

Jun 21, 2010Last 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?

Jun 23, 2010I 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..................

View 5 Replies View RelatedMacBook Pro :: Battery Calibration - Unable To Properly Sleep
Dec 2, 2009I 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...

Feb 27, 2012The screen turns red striped and you can still see the desktop in the background and it freezes up. I think it may be due to over heating because after forcing it to shut down it will restart after a short period. But if you try to restart it quickly it will beep at you. The laptop is about four years old but is used quite a bit. I try to keep it from being too beat up in transport but mostly it just sits on my desk. One thing that has changed is that I have been shutting it down every night before bed where I used to leave it running near constantly. The problems have only started after the new routine.

MacBook Pro :: SSD Degradation Over An Extended Period Of Time?
May 31, 2010Hey everyone, so I keep seeing posts about how much SSDs degrade over the first week/two after using an SSD (one that comes WITH the MBP). However, how much do they degrade after...say....6 months-1 year (or even longer)? I know they are still new hardware, but I'm sure some people have an idea. Is it really THAT significant of a speed and performance decrease?
