Earlier this morning, I was using battery power until the power drained quickly and unexpectedly. Once it shut down automatically, I could not turn it back on. It does not run on AC charge or battery. The mag-safe light is only a faint green, and I have reset my PMU. I'm hoping to not have to take it to Apple as it's warranty ran out about two months ago.
View 2 RepliesI was working late and let my battery drain while working. The computer shut down. I immediately plugged it in but the light on the power adapter didn't turn on (either orange or green) I tried other plugging it into other outlets. Nothing. I left it plugged in all night. Nothing. No light on the adapter and the computer isn't working.

My MacBook Pro is just under a year old.I don't do a lot of strenuous stuff... just internet, iWork documents, Sims 3, etc.The battery has been fine up until now, but on two seperate occasions it has completely drained in a matter of minutes.On the first occasion I left the MacBook open on my desk.No applications were open, just the desktop. Battery was at 98% after a full night's charge.I come back an hour later to find the computer completely unresponsive until I plug in the charger chord.It had completely drained.On the second occasion I was at 52% battery.I loaded up The Sims 3 and went to take a shower, planning to play when I got out.When I get out of the shower TEN MINUTES later, the computer was dead... once again completely drained.I know the game is a total battery hog, but I can usually get about an hour of gameplay with 52% battery.

rMBP charged overnight and I woke up at 7am and disconnected it, it is 9:30am and my battery is already at 34%. What ca I do? Only running Safari although a good portion of the morning was youtube videos. Still with some YT video playbacks here and there, should it drain this quickly?

I just popped in a brand new 15-inch MBP (square) battery into my 2008 MBP with Lion 10.7.4. It has drained to 84% in about 15 minutes. Is it a defective battery or a problem with calibration?

I have read about Macbook Pro batteries from apple.com. I use to talk to many people and ask about batteries which brought me upto this confusion. Well, my question is, should i charge macbook pro when it's battery is completely drained or it's okay to charge at any time as long as it's not at 100%? For example, I wanna start charging it while its 60% and make it to 100% or Don't charge it until battery reaches to 5 or 10 percent.

I got my first Mac last Sunday (woo!) but I was using it last night and a battery warning came up. I had been using the MBP, then turned it off and went out with battery still remaining. When I came back again a few hours later I used the Mac and after about 10 mins closed the lid for some reason. When I opened it back up it wouldn't start unless I plugged in the power outlet - the thing had completely drained. Then I checked the battery and it says to 'Service Battery'. It's now holding a charge as normal as far as I can see but the warning is still there.
A couple of other things I notice too:
- When I tilt the MBP to the right sometimes a scraping noise comes from the inside - maybe from a fan?
- When I pick it up from the bottom, the bottom of the Mac dips inwards slightly and there is a click as it makes contact with something on the inside of the case.
Are these things normal? I've made a Genius Bar reservation but I think I might just swap it for a new one.

When starting up it must be connected to the charger and when i turn it on it makes the bing noise, goes to the apple screen with the wheel turning for a second and shuts off. I have to do this multiple times until it works. Another issue that I am having is that the battery is draining very quickly. I just had it replaced a couple months ago.
I bought my Macbook Pro 13 inch last year in August. The health is on 88% with 84 cycles. Original battery capacity 5450 maH, current battery capacity 4809 mAH (Coconut and Istat Nano). I just read in another thread that there are users who have higher health capacity with many more cycles! I took it to the Mac store in Bangkok two weeks ago since I believe that my battery drains quickly. They run a test and told me that my battery is healthy. Then they also downloaded some updates for my Mac and run disk repair under disk utility. The technician told me that these are heavy programs and if they battery drains very quickly there is something wrong.
But according to him this was not the case. I have a 500 gb hdd and the technician said that since this is a big hdd (he recommended 320 gb maximum for 13 inch macbookpro), it will use more battery usage. I don't use heavy programs, only internet (Facebook, gmail, very seldom watch movies, watch news papers), Itunes and sometimes Word. I do a lot of photo processing, but this I always do with my adaptor plugged in. I think I can only use around 3 hours. Sometimes 4 hours. Screen around 80% brightness. Keyboard lights, bluetooth turned off. Do you think that there is a problem with my battery? Oh and I do calibrate my laptop monthly.
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.
View 15 Replies View RelatedMy MacBook Pro is 1 year old, almost to the day and my battery seems to be loosing all it's juice quite quickly these days. The battery cycle count is only 94. This morning I turned my computer on and I've only done emails. It's now about 4 hours since it's been on and I have 20% battery left. Bluetooth is turned off. Not doing anything any different than I used to. Seems to me the battery used to last 4 days for what I do with the computer. Now I charge it 2 or 3 times a day. I notice the underside of the laptop seems to get quite hot.

So I usually keep my UMBP plugged in at all times. It unplugged by accident and went to 99% so I left it unplugged but literally less then maybe 7 minutes my battery is already reading down to 92%. Brightness on screen is set all the way up, if that has anything to do with it.
View 1 Replies View RelatedThe last couple of days my battery has been draining extremely quickly, at full charge it indicates that I will get about 2 hours battery life when previously I was getting 6 to 7 depending on what I was doing. Also, I have noticed that the fan is running almost constantly and at high. I'm running os x lion and this is a late 2011 model MBP 13".Â

I recently was able to upgrade from a MacBook Pro Mid-2010 to a new MacBook Pro Mid-2012. I've only been using the laptop a few days, but it seems like the battery goes down from 100% very quickly. For example, right now I've only been using the computer for half an hour and the battery has gone from 100% to 71%. I haven't been watching movies, etc., just browsing the web.

I have an Apple 3-battery Wireless Keyboard, and I noticed that the battery drains out every 1-2 days. I don't own a Magic Mouse, and I know that's been the source of many AWK battery problems of late, but just to state it again, I don't own a Magic Mouse. I use Duracell rechargeables.
View 1 Replies View RelatedI own the first 'remolded' revision of the Macbook released in '08 (5,1), and have had it for over a year now. Recently though, after 10 or so minutes running off just battery power (fully charged), it shuts down unexpectedly. It doesn't say the battery is low, or near low, it just shuts down. It's really annoying, I have to use the charger wherever I go. I really need my laptop so I don't really want to take it to an Apple Store and have to wait a week to get it fixed, unless it's really necessary. My software is up to date. Any ideas on what my problem is/how to fix it?
View 2 Replies View RelatedJust wondering if anyone has ever encountered this or if any experts out there know of the issue.I have a spare White Macbook (late 2008: Core 2 Duo 2.1GHz, 1GB, 120GB) that I'd like to set up for my brother to use to introduce him to the wonderful world of Macs. The problem it is having is that when I have a battery connected to it (I tried 2 different ones included a known-good one that is brand-new just purchased from Apple) it powers on and gives me the chime, but then immediately shuts off unexpectedly giving that little "whine" sound like if it just lost power all of a sudden. However, when i take out the battery, and just plug it into the Magsafe AC charger it works fine. Also when just trying to run on battery it does not turn on at all. Here's some cliffs:
1) Macbook with just battery does not turn on
2) Macbook with battery + Magsafe AC charger connects powers on, gives the chime, but then immediately shuts off making the "whine" sound as if the power was suddenly cut off
3) Macbook with no battery connected and just the Magsafe AC charger connected works fine.Do you guys think this is either:
A) battery connector issue (the little piece with the metal wires that the battery connects to. ~$50 part)
B) Logic Board issue
I already tried resetting the PRAM and SMU to no avail.
I just turned on my 13" MBP and got this message. Apparently, this is supposed to come up when there is only like 5% charge left. My battery indicator at the top of the screen said there was 22% charge left. Also, according to IStat, my battery's health has already dropped down to 97% after only about 2 weeks and 5 cycles. Is this normal? I'm going to try recallibrating my battery by fully charging it and then letting it fully drain. Is there a good chance that this solves this problem?
View 1 Replies View RelatedI got my macbook during November of 2009 but two weeks ago it started shutting down by itself once I touch the magsafe of the macbook or remove the magsafe. All it needs is a simple touch and it shuts down. When it does shut down, the light indicator doesn't come on anymore. I have to keep removing the magsafe, and plugging it back in like 20 times until it starts charging again. So now I just let it fully charge every time I use it since any sudden movement will cause it to shut down. I will be making an appointment next week at the apple store because I had no time to go these past 2 weeks. I never dropped it and take good care of it. I am just wondering what might be the cause of this? I hope they do not take weeks to fix the mac since I have a lot of homework to do
View 4 Replies View RelatedAs I just bought a 13" MBA, I am still in my "babying" phase of the machine and want its battery power/capacity to last as long as possible. I have already done the battery calibration recommended by Apple (not even sure if its 'necessary' but I did it anyways), with charging, resting, draining, resting, and re-charging. But now I am worried about the battery cycles. Should I only plug my MBA in when the battery is close to being drained (aka use it on battery power for most of my usage?) or is it okay to drain the battery to like 80% remaining, charge, and then drain to 70% remaining, then charge again? Im not sure if Im making sense, but basically I don't want to be wasting these valuable cycles, as they seem to determine battery health and longevity. So what is the proper battery usage for the MBA, or is it basically use off power when you want and use on power supply when its available?

My girlfriend has a 12 inch Powerbook G4. She noticed that the battery life was starting to dwindle. Tonight, she tried using it. It wouldn't power up. The battery indicator showed one flickering power circle. The adaptor has the green circle on it, indicating the battery has a full charge. However, the computer won't charge up.I've read the 12 inchers don't have separate PMUs. Could that prevent the machine from starting? She was using it earlier this evening, as she e-mailed me pictures from our vacation.

I have a mid-2007 MBP. Here is my issue...it's been more than a year that when I totally discharge my battery (meaning the MBP shuts down), when I connect it back to the charge it is taking abotu 10 minutes to power up again...it was not the case before and my wife's MB is working well....meaning when it is down, just connecting the charger the MB is back on within a sec.
I have changed my battery but it did not change anything, I called Apple and they recommended me to restore snow leopard...which I did...I still have the same issue.
Does anyone experience this? Any idea what is happening (HW or SW issue) and is there a potential fix?
I have just bought a second hand MacBook laptop and it has a wierd battery issue that can't seem to find mentioned anywhere.Initally all seemed fine, but then I noticed the battery wasn't charging and the battery menu reported no battery found, also the MagSafe plug had not light; some searching instructed me to reset the SMC which I did, and everything was fixed, I could runs the computer from the battery and the power lead charged the battery. But now (just a day later) the battery won't power the computer at all - the computer will only work if the power is connected - however the light is shown on the MagSafe plug and the battery is being changed, but if I disconnected the power lead, first I see the restar/sleep/shut down dialog that you see when pressing the power button, then shortly after the computer turns off, if the power if reconnected, it boots from scratch, so it wasn't asleep!
