MacBook :: Dropped Battery Options With New Battery?
Dec 22, 2010
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.

Battery life on my MacBook Air (1.86/SSD) has dropped to less than two hours (for casual web browsing).When new, I got more than 4 hours on a full charge.Also, the battery meter seems to be way off.The machine shuts off with the meter showing 40% remaining. I've tried several full charge - discharge cycles.System information shows battery health to be good.

I bought a MacBook in late October, and it was my first, so I'm pretty new to Macs. Love it so far!
But anyway, here's my question -- my battery capacity has been at over 100% since I bought it, according to coconutBattery, and yesterday it dropped to 98%. I decided to calibrate it because I hadn't done that yet. So I let it put itself to sleep and left it that way overnight, then recharged this morning. When I first plugged it in, the capacity was at 99%. Now a few hours later, it's at 95%.
So, is it more likely that my capacity has been 95% for awhile and the calibration just helped synchronize the capacity display with the actual capacity, or did I really lose 5% in two days?!
I'm trying not to be totally crazy obsessive about this, but I really need a good battery life, and I want to keep this one going for as long as possible.

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?

I used to be able to use my macbook pro all day at school, from 8:50 till 16:00 without charging it at all, no problem. Suddenly however, over the easter holidays (about 3 weeks) It dropped significantly, barely managing 2 hours. During the holidays it was almost constantly plugged in to the mains, but this hasn't caused problems before, I've had it about 18 months and had longer holidays with no change. A few months ago I upgraded my ram from 4gb to 8, but it didn't seem to affect it at the time. (I know it still says 4gb in my info but the forums won't let me change that for some reason)
Info:
Mac OS X (10.6.5), 2.4 GHz intel core duo , 4gb 1067 Mhz ddr3

So I charged my battery to 100% and then unplugged it from the charger. Thats when the battery dipped to 97% instantaneously. It was very odd and somewhat scary. I just bought this MBP 2 days ago! Anything i might be missing? Is it supposed to do that?

A dad dropped my aluminuim Macbook 13" and the system runs fine, no issues with that, but I noticed the battery door had moved and wedged itself so there were gaps at the edges. I removed the door, and try as I might, I can't get it to line up properly.I'm really upset about this, as I've had it for a year now and really looked after it.I have the three year Apple Care plan, and I'm going to an Apple shop on Saturday about my iPhone anyway- do you think this problem is fixable?

So today I managed to drop my MacBook a short distance to the ground. I can't believe I did this. The computer was asleep at the time and, as far as I can tell, the internal HDD is perfectly fine. After I dropped the computer it wouldn't at first wake up from sleep. After removing the battery and replacing it, it booted back from the state saved to the HDD. My problem is that my optical drive makes noises now. I never use it, but whenever the machine tries to access it (waking from sleep, launching Disk Utility, etc) it makes noises as if the eject mechanism is running constantly or something else like that. The case also slightly bulges where the drive is. Now, if it doesn't work ever again I will only be slightly sad. I haven't tried to put a disc in it yet, but because of a previous spill by a previous answer the fibers around the opening are so stiff that getting a disc out of the drive when it works is a pain. Any ideas of what might be wrong and how to possibly fix it? I haven't tried resetting the drive, I don't have the time tonight.

I installed the new Lion software without any problems, everything runs great. But my battery life has dropped from 8 hours down to 2 hours.I am constantly having to charge the lap top to make it usable - I may have well purchased a desktop machine if I can only get two hours without charge?

I've got my SSD in an optibay and am using it as my boot drive. 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 just bought a 13" MBP on Monday and at first the battery was charging fully to 100% but now the battery only charges up to 99%. Even when my MBP remains connected to the wall socket the battery reads 99%. Is there anyway to fix this?

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

I'm trying to calibrate the battery of my new MBP. I need to get the battery to fully discharge and sleep for five hours or more. What are some things I can do to get my battery to discharge more quickly? Do I need to tell the MBP to not go to sleep after 10 mins of non-use, or the battery might last through the night? Or is it just the display that sleeps? I'd like to be able to use my MBP in the morning, but I'd like to make sure I get at least the recommended 5 hours of dead battery.

I recently purchased a 17" Mid-2010 MBP and put in 8GB and a OCZ Vertex 2 SSD drive. Ever since the upgrades and clean install of OS X, my system seems to not like to go to sleep when the battery gets low.Example, I was surfing the net earlier and the battery got down to 5% and I didn't get any type of warning that the battery was low. It went all the way down to 1% and then 0% and then just shut off instead of putting itself into sleep mode like it did before the harddrive and memory upgrade.

I have just completed rescuing a water damaged MB C2D which was originally a 2.16 and is now a 1.83. Fun project for a cold Sunday afternoon. 5 hrs I have one issue with the MB and that is the charging of the battery. The battery icon sometimes shows 'no battery' or if it shows a battery is recognized, it isn't charging. The LED on the mag-safe charger is always green. The battery is from the water damaged 2.16 and my thinking is that it may have suffered damage from being exposed to water. Original owner left the MB in the backyard and it started to rain!

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?

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!

If you look at apple's battery life page it states the MBA battery is removable, I thought it wasn't supposed to be?Battery Lifespan For Apple notebooks with removable batteries ? such as the MacBook, MacBook Air, and 15-inch MacBook Pro ? a properly maintained battery is designed to retain up to 80% of its original capacity at 300 full charge and discharge cycles. You may choose to replace your battery when it no longer holds sufficient charge to meet your needs.

I have an early 2008 non-unibody MacBook Pro. For about a year now, the status of the battery has been "replace soon." I was still getting a pretty good amount of time off of one charge so I wasn't too worried. This past Saturday morning, I woke up, checked the battery indicator lights on my computer (it had been sleeping since the day before) and it said it had about 60% percent so I opened it. I was on the Internet for about 10 minutes before it shut off without warning.
It wouldn't turn back on when I pressed the power button, so I plugged it in and it turned back on. When I checked, the battery status was "replace now." After using it, I turned it back off and left for NYC for the weekend and didn't bring it with me. When I got home last night, I plugged it in and tried turning it on with no luck. The battery indicator light was flashing one light, so I just assumed it would need to charge for a bit before it would turn back on. After about two hours, when I went to bed, it still was flashing just one light. I kept it plugged in over night, and this morning when I checked it, the battery indicator lights showed that it was fully charged, but it still wouldn't turn on. I still kept it plugged in throughout the day just in case, but it still won't turn on even though all the lights are lit. Is the battery just showing me false information, or should I be worried about more than just the battery?

purchased a macbook Unibody back in October 2008 when they were released and use it heavily. The battery no longer holds a nice long charge - I get about 2 to 2.5 hours out of a full charge.
The battery has 149 cycles on it, which is obviously high (and correct, I use the hell out of it). With it still being in warranty, is it worth pursuing a replacement battery? Will Apple tell me to go take a hike with the high cycle counts?

i just ordered a late 2008 macbook pro 15 with the dual GPUs (9400m and 9600m GT) and I'm a little worried about the battery life.
-What can I expect if just doing normal every day stuff (web surfing mostly?)
-does watching a movie off of the hard disk use less battery than watching it off a DVD? Is there a big difference?
I'm not a big gamer but would like to have the horsepower to play a game should one come out that I want. I'm also not a big traveler so battery times are only of average importance.
Basically, I'm asking if I made a good purchase considering I have only average concerns for both battery and game performance. They had the new 7 hour battery 15" macbook pro for the same price but it doesn't have the dual GPUs.

been using my older MBP with windows 7 for a while and have never notice oddies with the battery until now. Then recently after replacing the failed HD and re-installing Snow Leopard on my 2007 MBP, the battery panel is telling me "Service Battery"; it's battery health according to coconutBattery is fair for it's age (50%).
the unit (battery) has been replaced previously due to being considered 'under performing'. Is Snow Leopard trying to encurate it's users to replace the battery more frequently? If not, does anyone know why this appears? I'm at lost, since it appears to work fine, if not charging completely.

I'm not sure if this is SL related, but I get the service battery warning when I click on the battery status. iStat reports it at 62% health. Rev B 1.6 just 6months old. Should I bring it to apple or is it just a bug of SL?
