MacBook Pro :: 13" Battery Draining While On AC Power?
Jun 24, 2010
The title says it all, basically my MBP's battery drains even if the computer is plugged. When I sat at my desk to use my MBP earlier today I noticed the battery was charging. That seemed very weired, I was sure it was at 98% last night. I decided to switch my computer off and let it charge all the way up.
When I turnt on my computer again i checked the battery and everything seemed normal, but after half an hour or so I noticed that my battery status icon had chaged from charged to not charging. I loaded up Coconut battery and the battery was slightly over 90%...and it's still draining out while tipyng... The AC socket is fine and I have an HDTV connected to the same power source. Needless to say the tv is working normally... I do not have an Apple shop nearby, the closest is over 200 km (approximately 140 miles) away.

Recently I've been noticing that my MacBook Pro's battery has been draining really fast. It's draining about 5% every 7 minutes. The battery condition is normal and it only has about 290 cycles on it. My brightness is turned all the way down, bluetooth is off and the only application I have open is Google Chrome, and I'm only using it to do some light browsing. Does anyone have this same problem? I have a MacBook Pro (mid-2010) running the latest version of Lion?

-Processor Speed: 2.8 GHz
-Memory: 4 GB
-OS X Version 10.9.3Â
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 have recently started using iTunes to listen to music while surfing the web or using other non intensive programs such as Inkscape. It appears that iTunes decreases my battery life considerably more than any other program that I use, even if I have a song on pause. While using iTunes my fully charged battery will display 4 to 3.5 hours of life remaining. When I have iTunes closed my computer will display a battery life of 7 to 9 hours, often with usage times the exceed that. Has anyone had similar experiences with iTunes and poor battery life, or am I doing something wrong here?
P.S. I have already calibrated my battery.

This morning I set to work on my laptop as usual. I typically leave it plugged in while not moving around, and today was no exception. I h ave a 15" macbook I purchased in December of 2010, and it's currently running OS X 10.6.8, if that makes a difference.
Anyhow, when I started up my Macbook and set to work, the battery was fully charged (indicator read that it was fully charge, and that the power source was the power adapter). The power adapter light was green. I then stood up and did some work for roughly 2 hours away from the laptop. When Ieft, I put the display to sleep - In the background the machine was still running a webbrowser (reading an all-text page) and preview (a PDF was open). This is nothing out of the oridinary, and I do it all the time usually.
What was unusual was when I returned to my machine after 2 hours of idling (with the display asleep)Â to find that my battery had been almost completely drained. The power adapter light was now orange, and the indicator showed that the battery was only 4% charged. The power source was still displayed as the power adapter.
I understand that during intense processses the Macbook will draw from the battery AND the power adapter - But my Macbook was simply idling! I can't fathom that a webbrowser and Preview would require THAT much draw for power. In fact, I've run my Macbook MUCH more intensely for much longer periods of time when running Final Cut and Adobe After Effects and NEVER seen this issue before.
Is this an indication of a failing battery? Ever since I noticed this, the charging time indicated has held steady at ~1:13 (that's been about a half an hour now). I don't know if the Macbook will discharge the battery completely every so often by itself, or if the battery is just failing and that's why it went from 100% to 4% in just under two hours while idle.

The 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

After installing the update for Mac OS (10.7.4) my battery starts too drain too fast. As usual after 100% charge my laptop showing me time near 5 or 6 hours. Of course I understand that this number is relevant, but i always get this numbers when using not so heavy apps (Safari, Mail, Pages, Twitter and iTunes), but now i can see only 2 or 3 hours. After long searches i found the problem. My MacBook Pro 15 inch have problem with graphic-card changing, it always changes to AMD Radeon card when I start Twitter or Reader! I think that Twtitter is not so heavy app that must use diskrete grpahic-card. And because I always run Twitter in background my MacBook Pro's battery drains in a few hours.

It shows a battery capacity of 5393 mAh out of 5770 mAh with a condition of "normal" at 93% health. The issue is that the battery has been draining MUCH faster than usual. Yeah I know it depends on what I'm doing/Youtube/Flash blah blah blah. I get it. What usually took 6-8 hours of normal time to drain is now taking 2 hours, max. I reset the PRAM, etc --- not much different. Now, here's the BIG issue. I have NEVER been able to recalibrate my battery because after it hits 10-15%, the computer just shuts off. It never goes into sleep. This has happened every single time. Has this ever happened to anyone before? The Apple Store is ways away, and I don't want to waste time going if they're just going to tell me my battery is "normal" since I haven't hit my 80% health indicator.

Several weeks ago I upgraded my mother's MacBook to Lion. I had also intended to buy lion for myself but my iMac's hard drive died.Since Lion was installed the MacBook's battery life has been very, very poor - even booting up can cost 5%. A lot of people gave been discussing this. I have googled this issue and emailed Apple, but there seems to be no solution on the horizon. So I am going to reinstall Snow Leopard on the MacBook.  I had intended to contact Apple to see if a refund would be possible. However, just yesterday I replaced the hard drive in my iMac and it is working fine now. So I was wondering since I paid for the Lion OS, is okay for me to install it on my iMac rather than attempt to get a refund. Is that legal? And would it work? Would the fact that it was bought using my mother's AppleID (my money though ;)) mean that if I install it on my iMac it will make my computer my morher's computer - meaning my morher's login and details will overwrite mine?Â

I installed the hard drive with no problem and have experienced greater performance, no clicking nor vibration, and no freezeup or rainbow wheel. I also did a clean install of Snow Leopard. I did a PRAM reset at the beginning and calibrated my battery. However, now I noticed my battery is draining FAST, only lasting 2 hours. I looked a little online and discovered I may still need to reset the SMC (shift-control-option + power key), which I will do shortly. The battery lasted 6-7 hours before with my old hdd and is at 96% capacity.

Just 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?

As 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?

I recently discovered my computer had died while it was sleeping. I tried charging it but am recieving the "Battery not charging, power source: power adapter" status.My power cord light is green, always. and the computer dies instantly when I remove the magsafe.
I've tried the "remove the battery, press the power button, plug in the magsafe" troubleshooting process, but it doesn't work.I've noticed that even with the battery out, the charger reads a green light.I've tried several outlets with the same results.Here are my battery statsÂ

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!
