MacBook Pro :: 17 I5 - Battery Calibration - Shut Off Rather Than Going Into Sleep?

Jun 23, 2010

I 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..................

MacBook Pro :: During Battery Calibration - Turned Off Instead Of Sleep?

Sep 11, 2010

Ok, 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.

MacBook Pro :: Battery Calibration - Unable To Properly Sleep

Dec 2, 2009

I 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...

MacBook Pro :: Last Step In Battery Calibration?

Aug 5, 2010

When 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.

MacBook Pro :: Battery Calibration - Power Cord

Oct 12, 2010

Well 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??

MacBook Pro :: Weird Battery Behavior After Calibration?

Nov 11, 2010

I'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.

MacBook Pro :: Battery Calibration / Unplugged While Recharging

Jul 19, 2009

I 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.

MacBook Pro :: Battery Heath Dropped 10% After Calibration?

Jun 21, 2010

Last 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?

OS X :: Oddities With Battery Calibration?

your battery drain in your laptop to 0, and then charge it to full? I am under this assumption. Please let me know if this is wrong.Anywho, so today I decided to let my battery drain to 0, and then normally it would sleep and I'd wake it up after plugging it in.. but this time I had to actually press the power button, and a gray screen appeared with a meter-like thing to illustrate it "waking up" I guess?

MacBook Air :: Battery Drains Extremely Fast In Sleep Mode / Battery Down To 16% From 29%

Jan 6, 2009

I get the whole part about that I set my laptop to go to sleep in 5 minutes, and if I close the lid it'll go to sleep, and the little light at the bottom starts to pulse, etc. But in sleep mode, my battery seems to drain extremely fast!

For my old Gateway M275 laptop while in sleep mode, it would probably lose about 5-7% of it's battery in a day's duration. With my MacBook Air, I just came back to it tonight after a day's worth of sleeping, and my battery was down to 16% from 29%. And to check, it was indeed sleeping!

MacBook Pro :: Shut Down Instead Of Going To Sleep?

Jun 16, 2012

I had some weird issue with my MBP last night. I let it running when I went to sleep so it could finish a download for me. The battery was fully charged, and I've done it in the past, and MBP would just go to stand by after it finished the download. But this time when I woke up it was turned off completey. I thought it was the battery, so I connected it to power to charge it again, and all of a sudden my MBP turned back on without me pushing any buttons or so. I than had to sign on again and when I checked the battery it wasn't empty, so MBP should have gone to sleep instead of shutting down.

After I signed on I was told that date and time had been set back to the original settings and I had troubles connecting to the internet. When it finally worked again after about 45 minutes I was asked to allow configd and mDNSresponder access, that also never happened before... 

Is there anyone who could explain to me what happened or what might have caused this?

MacBook Pro :: Will Battery Eventually Shut Down?

Jun 16, 2010

Lets say the battery been use extensively to the point where full charge will only last like an hour. Does it mean in time, the battery will weaken to the point to where you can't even turn on the macbook pro anymore? I was hoping that since the places I am traveling will have an electrical outlet. I wouldn't think I would need battery life for over 3 hours.
