Macbook pro discharging batteries

I have two Macbook pros (2,2) both work fine from ac and charge the batteries, however one was losing the charge much faster when not connected to ac. Battery %age dropped from 100% to 74% in 30mins. The other one takes nearly an hour for the same.
To test it I swapped the batteries - however the original behaviour is still happening with the different battery. Any hints as to what I can try next?
thanks,

MacBook Pro discharges whilst off?

Hi folks,
New MacBook Pro retina, 4 charge cycles on the clock. Have noticed that if I charge the MacBook then leave it turned off and don't touch it (fully off, not asleep), I lose 2-3% of battery every 24 hrs or so. I know batteries discharge naturally when not in use, but is this rate of discharge normal? This is my first MacBook, I can't recall ever seeing this rate of discharge on a PC laptop before...?
Cheers, Gopha

Keep it plugged in when near a socket so you keep the charging cycles down on your LiPo (lithium polymer) cells / battery, but not plugged in all the time. When not being used for several hours, turn it off.
http://www.apple.com/batteries/notebooks.html
"Apple does not recommend leaving your portable plugged in all the time."
General rule to remember of Lithium batteries is:
Never drain them LOW & dont always/often store them HIGH
While cycle count is commonly seen to be the “miles” on your Lithium Ion pack cell in your Macbook, which they are, this distinction is not a fine line at all, and it is a big misconception to “count charge cycles”
*A person who has, for example, 300 charge cycles on their battery and is recharging at say 50-60% remaining of a 100% charge has better battery usage and care than another person who has 300 charge cycles at say 15% remaining on a 100% charge.
DoD (depth of discharge) is far more important on the wear and tear on your Macbook battery than any mere charge cycle count. *There is no set “mile” or wear from a charge cycle in general OR in specific.    As such, contrary to popular conception, counting cycles is not conclusive whatsoever, rather the amount of deep DoD on an averaged scale of its use and charging conditions.
                          (as a very rough analogy would be 20,000 hard miles put on a car vs. 80,000 good miles being something similar)
*Contrary to some myths out there, there is protection circuitry in your Macbook and therefore you cannot overcharge it when plugged in and already fully charged
*However if you don’t plan on using it for a few hours, turn it OFF (plugged in or otherwise) ..*You don’t want your Macbook both always plugged in AND in sleep mode       (When portable devices are charging and in the on or sleep position, the current that is drawn through the device is called the parasitic load and will alter the dynamics of charge cycle. Battery manufacturers advise against parasitic loading because it induces mini-cycles.)
Keeping batteries connected to a charger ensures that periodic "top-ups" do very minor but continuous damage to individual cells, hence Apples recommendation above:   “Apple does not recommend leaving your portable plugged in all the time”, …this is because “Li-ion degrades fastest at high state-of-charge”.
                    This is also the same reason new Apple notebooks are packaged with 50% charges and not 100%.
LiPo (lithium polymer, same as in your Macbook) batteries do not need conditioning. However...
A lot of battery experts call the use of Lithium cells the "80% Rule" ...meaning use 80% of the charge or so, then recharge them for longer overall life.
Never let your Macbook go into shutdown and safe mode from loss of power, you can corrupt files that way, and the batteries do not like it.
The only quantified abuse seen to Lithium cells are instances when often the cells are repeatedly drained very low…. key word being "often"
Contrary to what some might say, Lithium batteries have an "ideal" break in period. First ten cycles or so, don't discharge down past 40% of the battery's capacity. Same way you don’t take a new car out and speed and rev the engine hard first 100 or so miles.
Proper treatment is still important. Just because LiPo batteries don’t need conditioning in general, does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesn’t need conditioning.

Storing your MacBook
If you are going to store your MacBook away for an extended period of time, keep it in a cool location (room temperature roughly 22° C or about 72° F). Make certain you have at least a 50% charge on the internal battery of your Macbook if you plan on storing it away for a few months; recharge your battery to 50% or so every six months roughly if being stored away. If you live in a humid environment, keep your Macbook stored in its zippered case to prevent infiltration of humidity on the internals of your Macbook which could lead to corrosion.
Considerations:
Your battery is subject to chemical aging even if not in use. A Lithium battery is aging as soon as its made, regardless.
In a perfect (although impractical) situation, your lithium battery is best idealized swinging back and forth between 20 and 85% SOC (state of charge) roughly.
Further still how you discharge the battery is far more important than how it is either charged or stored short term, and more important long term that cycle counts.
Ultimately counting charge cycles is of little importance. Abuse in discharging (foremost), charging, and storing the battery and how it affects battery chemistry is important and not the ‘odometer’ reading, or cycle counts on the battery.
Everything boils down to battery chemistry long term, and not an arbitrary number, or cycle count.
Keep your macbook plugged in when near a socket since in the near end of long-term life, this is beneficial to the battery.
Peace
General consideration of your MacBook battery
Contrary to popular myths about notebook batteries, there is protection circuitry in your Macbook and therefore you cannot ‘overcharge’ your notebook when plugged in and already fully charged.
However if you do not plan on using your notebook for several hours, turn it off (plugged in or otherwise), since you do not want your Macbook ‘both always plugged in and in sleep mode’.
A lot of battery experts call the use of Lithium-Ion cells the "80% Rule", meaning use 80% of the full charge or so, then recharge them for longer overall life. The only quantified damage done in the use of Lithium Ion batteries are instances where the internal notebook battery is “often drained very low”, this is bad general use of your notebook battery.
A person who has, for example, 300 charge cycles on their battery and is recharging at say 40% remaining of a 100% charge has a better battery condition state than, say, another person who has 300 charge cycles on their battery and is recharging at say 10-15% remaining on a 100% charge. DoD (depth of discharge) is much more important on the wear and tear on your Macbook’s battery than the count of charge cycles. There is no set “mile” or wear from a charge cycle in specific. Frequent high depth of discharge rates (draining the battery very low) on a Lithium battery will hasten the lowering of maximum battery capacity.
All batteries in any device are a consumable meant to be replaced eventually after much time, even under perfect use conditions.
If the massive amount of data that exists on lithium batteries were to be condensed into a simplex, helpful, and memorable bit of information it would be:
1. While realistically a bit impractical during normal everyday use, a lithium battery's longevity and its chemistry's health is most happy swinging back and forth between 20% and 85% charge roughly.
2. Do not purposefully drain your battery very low (10% and less), and do not keep them charged often or always high (100%).
3. Lithium batteries do not like the following:
A: Deep discharges, as meaning roughly 10% or less on a frequent basis.
B: Rapid discharges as referring to energy intensive gaming on battery on a frequent basis (in which case while gaming, if possible, do same on power rather than battery). This is a minor consideration.
C: Constant inflation, as meaning always or most often on charge, and certainly not both in sleep mode and on charge always or often.

Iphone ruined my macbook pro retina batterie? is this possible?

Hello,
I have a macbook pro retina 15" and sudenly the batterie stoped charging.
A few nights before i left my iphone 4 conected to it because i had no charge on it. Later in that morning the iphone was charged (and the laptop wasnt connected to the ac charger)
I went away for a week without the laptop and when i returned and tryed to charge the computer. So i pluged the charger. 6 hours after, the red light in the charger was still on. (The charger is brand new, bought online in november 2013)
I found it strange and pressed the power button on the laptop.
it started normally while connected and the battery icon said it has 28% of battery, but it also has the info that its not charging and to replace the batery. A few minutes after using the laptop it sudenly turns off. I unplug the charger and it doenst power on hen i press the power button, but when i connect the charger he assumes it and powers on automaticly. I also made the SMC reset but with no positive result.
The one year warranty expired two months ago, and since it was bought on the USA and i live in Portugal im having some issues trying to solve this.
I went today to a mac premium store here in Lisbon, Portugal and they sayd i have to replace the top bottom (?) where the battery is located. They just asked for 530€ (aprox 750 dollars) just for the replacement part.
The guy from the store said that you should never leave your macbook pro stored with 100% battery, always between 40 and 60%, is this true?
Im having a huge trouble in acepting this because i dont use the laptop while charging, i always let it almost empty before charging again. and i dont use it a daily basis.
Is it possible a computer so expensive has so many problems?
Someone has an opinion or idea?
Thanks
Pedro

Start by calling Apple Support at the country number from http://support.apple.com/kb/HE57 as the info from the person you talked with is incorrect.
You can leave the MBP with a full charge with no problems, in fact that is the best thing to do.
The iPhone charging did not damage the MBP battery, the failure of that battery is another issue.
When you say you bought the MBP charger on-line, is it an Apple charger or third-party charger? Many thiord-party chargers do not output the correct power (voltage and current) for the computer and do cause damage to the battery and charging circuitry.
Talk with the Apple Support people and see what they recommend and how to proceed.

MacBook Pro destroying batteries

Ok guys...I have an issue with my MBP. Ive had it for a long time now and it has had a few trips to the apple store to see what the problem was. Im posting this to share with you, my crazy experience that im still not out of. Maybe some of you have had this problem, but whatever info I can get would be helpful.
My problem will be best put into a little timeline.
My MBP was purchased in July of last year (06). It came out of the box working wonderfully and without one single problem..no whine, no screen issues, Nothing. It served me well from the start, and continued to untill about 5 months ago.
The first incident took place in school when my computer was plugged into the AC power connector. Someone unplugged it for a second to connect my plug to a power strip, and "poof" my computer went dead. Out of nowhere.
I didnt really think there was a problem until I pushed the charge indicator on the battery and found out that the battery was fully charged! Through experimenting with it, I found out that the only way my computer stayed on was to be hooked up to the AC power into the wall. This is a problem considering my laptop's main purpose is to be portable.
I scheduled an appointment that week and took it down and got it checked out. The guy was really cool about it and explained that some batteries are just bad, or go bad over time. I was pleased to hear that, and remembered reading something about a battery recall. So he placed a new battery in and like magic, the MBP came on and worked on its own! I was happy that it wasnt my computer, and that it was just a defective battery.
The new battery he gave me worked wonderfully, for about, 3 months. Then, one day, out of nowhere, "poof" , It just died again after being removed from the wall on full charge. Like I said before, It would power on, and work fine while plugged in, and the battery read as fully charged.
I still wasnt too concerned because I saw how easily it was fixed before and just thought, maybe there are a lot of faulty batteries out there.
Took it back to the store 2 weeks ago, and told them of my previous visit for the same issue. He told me that it could be the logic board or the battery. Then, he put a new battery in and it worked again perfectly, so he said it was the battery and not the logic board. Once again, my computer worked and I was satisfied.
One day soon after, my AC power connector was plugged into the magsafe slot on my computer, I was just working on the computer normally, when smoke began to rise from the magsafe connector. I quickly unplugged it and looked at it closer...The wires had actually gotten hot enough to melt the cable almost half way through! so I have this melted magsafe cord now that cannot be used. Luckily, my girlfriend also has a mac and let me share hers for all this time. So I was planning on getting down to the apple store this week...
Then, last night, I was working on my computer while plugged into AC power again. I moved from where I was sitting and bumped the magsafe connector off of its slot on my computer and once again, I hear that awful sound of your hard drive spinning to a halt when your computer completely dies!
Yeah...three times this has happened. Im concerned now and worried.
So basically, Im worried what can be done about this. I dont understand it, Im pretty sure that ALL 3 batteries were not defected. That would be too crazy considering almost everyone else I know that has one has an ok battery. So Is my Macbook Pro destroying the batteries? Did It destroy the magsafe?
Im not sure what to do...Has anyone ever had a magsafe replaced due to the same situation? and if anyone has a clue, what could be causing my computer to kill batteries completely over the course of 3 months?
Let me just clear a few points up so that you understand some things that I have already ruled out...
1. I understand that a magsafe is not meant to be pulled out by the cord and never once removed it like that. I tried to educate myself in the right way to preserve my computer. I read about them breaking because people pull on them hard, but I can assure you that never happened.
2. My computer only does this on batteries that it has for long periods of time. In other words, at any given moment, I can grab my friend's MBP battery and put it in my computer and it will work just fine. So I ruled out that maybe my computer isnt able to recieve the battery power. If it was a problem like that, then why do other batteries work fine?
therefore, it has to be the batteries, but something that happens over a few months use.
3. I understand that batteries eventually die out. But I also know that it takes a while for that to happen normally. Im not one of those people who leave my computer charging all day, or on all day for that matter. My computer use is what I would call very normal and average. Average enough that a brand new battery loses capacity in two weeks. Not to mention, the batteries are fully charged.
4. last thing.....my "defective" batteries wont power any other MBP's either. So its not just my computer being funny about connecting. But maybe that its ruining the batteries.
I dont know what to think. I cant explain it. I love Macs and understand that there are problems that can happen with any technology, but I just dont want to end up spending a complete fortune fixing this thing and Im worried that is the road im headed down.
I realize this post is extremely long. I thank whoever made it this far. Im just trying to include everything so that you completely understand as best as you can.
anything you can tell me would be so helpful. I have another term of school coming on tuesday and this huge problem on my hands.
Thanks!

Lithium ION and lithium polymer batteries have a built-in microprocessor to control the charge rate of the battery. A lithium battery that is overcharged can overheat and catch fire or explode. If the microprocessor determines that the battery is in danger, it can permanently disconnect the battery cells from the outside world. Coupled with the fact that you have had a magsafe connector fail from overheating, I think the charging circuit in your MBP needs to be replaced.

A few questions about Macbook Pro 13inch batteries.

Hey, my Macbook Pro just arrived today, and I was wondering about general battery care:
Is it okay to leave it plugged in while using it?
How come there's a longer power cord and a shorter one? Is it just for convenience?
How long does a Macbook usually take to charge to 100%?
Is it okay to leave it plugged in all night?
Sorry if I sound stupid, but I'm not very tech-savvy. Thanks for any help!
xx

Yes, you can leave it plugged in. Once in a while however, you have to use it under it's own power, at least till it reaches 80% to keep your battery in optimal condition.
As for the power cord, you answered that one yourself " for convenience "
How long does it take long to charge all depends on how low the battery was when you charged it.
Yes, it's ok to leave your Macbook plugged in all night. Just make sure you use it under it's own power once in a while. You don't have to fully discharge it which might do more harm than good.

TS3048 The keypad is not registering with my macbook pro - changed batteries but still not working. Bluetooth says it is connected. Suggestions please.

My bluetooth numeric keypad is not registering with my macbook pro - changed the batteries when the light started blinking - but won't work. Bluetooth says it is connected.
Suggestions please.

Your MBP sees the Bluetooth keyboard but won't pair with it probably because the keyboard is pairing with another computer or device nearby. If you had previously paired the same keyboard with another device, go to the other computer or device and either unpair it or have the device "forget" the keyboard. Then you will be able to pair the keyboard with your MBP.

Macbook Pro discharges battery when turned off

I've had my Macbook Pro 15" for close to a year now (Mid-2010 revision), and this issue has only happened a couple of times, where when after shutting down the machine at night (full shut-down, not sleep), I turn it back on in the morning to find that the battery has been completely discharged. I thought that the first time, which happened some time ago, probably a few months back, had been me accidentally leaving the computer on running a program which drained the battery, but the most recent incident I am fairly certain that the machine was powered down fully before unplugging the power cord and any other attachments for the night.
I was wondering if this has happened to anyone else, and if it is a major problem? I don't have AppleCare, but may consider getting it before my warranty is up if needed (in about a month) to diagnose/fix the problem with the least trouble/cost. Not afraid to open up my machine if the forum members suggest it, but because the problem is impossible for me to replicate, any solutions (baseless or not) may or may not help and I won't be able to confirm it.
Any help is appreciated!
Steve

Battery health is normal, 97-100% when fully charged and discharges normally when under regular use with the power cord unplugged (about 5-6 hours of usage when under moderate load, can sleep for 6-7 hours and only see a 2-4% drop). WIll post info from the system profiler in case it helps.

Can you charge Macbook pro A1297 batteries externally?

I hav a Macbook 17" Core i5 Unibody A1297 which doesnt charge due to a motherboard fault - The battery ISNT removable without unscrewing it .... but is ther a way to charge it externally?
cheers,

I Thought this might be the case with nothing commercially available....and not being able to afford the mac repair to the logic board (it may not be fixable ... and too expensive to replace) - I may have to try and see if I can build something - I will have to try and get the pin-out for the battery and the charge circuit

MacBook Pro discharges partially while sleeping, why?

Hello here,
I noticed that, unlike earlier when I started to use this Mac, if I leave it sleeping in my bag during half of the day only to wake it up later, the battery only holds a charge of anywhere between 75 and 90%.
Of course, the Console doesn't record anything between the time I put it to sleep and the time it is woken up.
How to correct this bug and revert to the standard behavior, i.e. sleeping soundly until needed, without losing more than 1% every 48 hour?

Well, if I am to leave my MBP unused for 2 days, I would leave it plugged in and fully turned on so as to allow for automated backups to be made, especially remote ones (back when SpiderOak worked anyway) as I can't expect a multi-gig upload to complete in a matter of minutes.
Sure, no problem. No harm done in keeping it plugged in and no overcharge will occur. Sugggest you set Energy Saver to turn the display OFF after a reasonable interval, rather than have the screensaver burning the LEDs unnecessarily.
This still doesn't really answer my questionas to why this Mac seems to be burning through the battery when sleeping.
RAM's gotta keep alive, especially if sleeping rather than hibernating. And I suppose faster RAM will need more juice, even if in low power quiesced mode. Back in the days of 667MHz DIMMs would need less than today's 1600MHz SO-DIMMs. Have noted direct correlation with RAM usage: low drain of no apps are running - high drain if everything + kitchen sink is left going prior to sleep.
How can it be compared to the boasted capability of other Macs to retain their charge for up to 30 days while sleeping?
Where would that boast be found? Have read Apple boasting that modern batteries last IN USE throughout a working day (~8-10 hours), but never seen anything about "sleeping beauty" Macs....

MacBook Pro Late 2008 - Batterie almost down - is this correct ?

Hi there,
I got a 15" MacBook Pro which I bought in May 2009. I have always done my best to keep the battery in good condition. Running it until the computer shuts off, charging it all the way, calibrating it twice a month and so on. Now it has 208 charging cycles and only 60% of the original capacity are left
Is the OK ? Apple says it´s supposed to have 80% after 300 cycles.
Thanks for your answers.

While a lot of talk about Li batteries makes it sound like a cycle is a cycle, not all cycles are truly the same.
Most Li batteries will actually decay more slowly with frequent partial discharge/charge cycles. Repeated or very frequent single use, full cycles will actually speed up the decline in your battery.
That's why it is unwise, and completely unneccesary to calibrate more than once a month (or, in my personal opinion, more then once very 2-3 months).
So, honestly, given what you wrote about your useage, and with 208 cycles, I would guess that you are seeing not unusual decline in battery performance.
Note too that heat also plays into it - if you use your machine a lot in hot and/or humid environments - that can accelerate the decay of a Li battery.
The 80% after 300 cycles information is really just an average, and certainly based on optimal conditions at all times. I have had heavily used Apple laptop batteries (i.e. used much as you've done with yours) die after 12-18 months of such use and at less then 300 cycles, they were useless. Others that I have, have gone well past 300 cycles and still been quite useable, but they were used differently (partial cycles, only calibrated a few times per year, only used indoors in climate controlled buildings).

New Macbook Pro Wont turn after discharge

Hello everyone,
I just purchased my 3rd mac in the past 2 years, yeah that's how hooked I am, now windows free 99% and love it...
My brand new macbook pro has a very annoying issue.. if I use it on battery power and it discharges completely I have to wait up to 15 minutes after connecting it to power to be able to turn it back on again. this is so frustrating as I am sometimes doing some work and have to get away from the computer for a few minutes.. If it discharges within that time and I come back to continue my work guess what.. I need to wait all this time even after connecting it to power to resume my work...
Does anyone has the same problem? is this normal? I've searched google and haven't found the same problem on anyone else unless they are OK with that and just don't report it... I've never had this problem with any other laptop I own and is extremely annoying, my wife's macbook doesn't do that, if it discharges and goes to sleep you can just connect the magsafe adapter and it will come right back up.
your comments will be greatly appreciated.

My MBP has always come back immediately. So has my old iBook. I rarely discharge my battery completely, but will do so on occasion to calibrate it. But I have never had the problem you describe. My personal opinion is that the long delay is definitely not normal.
Out of curiosity, next time your Mac shuts down like this, remove the battery and see if it will start up immediately. If it does, you could possibly have a faulty battery. If it still takes a lot of time to start up with the battery removed, there is something else wrong. I have never heard of anything quite like this. Since you didn't mention excessive heat, that wouldn't be a factor.
Be sure you can reproduce the condition for the Apple genius. They have to see it to be able to do anything. Go in a bit early with a low battery and run it out in the store, so you can show them exactly what it is doing.
Good luck!

Why does my MacBook Pro battery discharge even when the charger is plugged in?

I've been having a myriad of problems with my MacBook Pro's battery. The main problem is that when in use, the battery steadily discharges often at a very quick rate even when I have the charger plugged in, the only way I can get it to recharge is to close the lid or turn the computer off, however, it has recently started to take a very long time to recharge (I left it for 12 hours and it charged from 0% to 60%). I also noticed that while off, the charger light occassionaly goes green and then back to orange every few minutes. When I manage to get the battery up to 100% charge, it usually stays at 'Charged' for around 5 or 10 minutes and then it just comes up with 'Calculating...' as it slowly discharges, it also occassionaly claims that it is recharging and that it will take around 6 to 8 hours but it only charges about 1% of the battery and switches to 'Not charging'. Also, sometimes the charger light wont come on when it is plugged in and the Mac refuses to acknowledge it is plugged in for some time.
I took it to the Apple Store a few months ago and one of the Geniuses reset the System Management controller and did a quick hardware test which seemed to fix it but the problems returned soon after, I cannot enter the hardware test screen and subsequent attempts to reset the SMC have done nothing, he also tested the charger and tried it with another charger but it did not help. Hope you guys can help me as I am completely stumped by this and its beginning to annoy me as my Mac is becoming almost unusable.

Battery condition says normal but cycle count is on the high side.
May be better off with a new battery.
Hope everything turns out right.

After a year of no use and a fully discharged battery, my MacBook Pro refuses to accept the administrator name and the password. How can I reset these?

After a year of no use and a resulting fully discharged battery, the MacBook Pro refuses to recognize the administrator name and password (both). It has system OS X 10.6 which can not be upgraded without the information. How can I reset or reistall the administrator name and password?

Thanks to all who responded. You are all absolutely correct. However, this Ipad was a gift to my wife who was dying of cancer in the hospital and wanted some entertainment. So I started it out with her Apple ID. After she passed away I moved from Sacramento to Austin and eventually proceeded to get the Apple ID changed from my wife's to mine. Meanwhile when she was in the hospital I opened an Itunes account in my name to buy movies for her. That was the first mistake.
Then during the move to Austin I lost track of the IPAD and later found it and tried to use support but could not remember the proper ID. Later the folks at the Apple store helped me create a new and novel Apple ID that was unfortunately unlike any other.
The botom line is that I am stuck with three Apple IDs and three passwords. I am told by Apple there is nothing they can do about this as IDs cannot be changed or destroyed. I can quit using them or start a new account but when I try to do that the system keeps remembering too many things from the past and resists.
Even if I sold this Ipad and bought a new one, the system memory is still there.
I think the real problem is that destop and laptop computers are totally owned by an individual and that individual can control logins and passwords to his liking. IPADs and similar Apple products are different in that the corporation has built in their own intrusion detection schemes because of the relation to Itunes.
One thing I thought about is to open a new Itunes account pretendding to be a new customer with my regular Apple ID. Perhaps I could do the same with Apple Support.
Thanks for your comments.

Macbook Pro Retina display says "No batteries available" after legitimate system software update

Issue Description
On July 26, 2012 I placed an order with Apple store for the 15-inch MacBook Pro with Retina display with the following configuration (Order # W269108641 Serial# C02J52S9DKQ5):
Processor 2.6GHz Quad-core Intel Core i7, Memory 16GB 1600MHz DDR3L SDRAM, Flash Storage 512GB Flash Storage
It was delivered August 8, 2012. It cost me $3,265.16
I have since equipped it with accessories like a wireless apple keyboard ($69), wireless mouse ($69), USB super drive ($79), VGA display adapter ($29), Ethernet Adapter ($29) and the excellent sleeve/pouch from Pack & Smooch GmbH (GBP60))
It's so heavily configured because it’s my main workstation. I additionally bought and installed Parallels 8 so I can run Windows 8 in a Virtual Machine because I have a few things on Windows that I need to be productive. This setup has been a dream machine until a little over a week ago.
In the one year since I bought it, I have had only 2 issues;
• A case of display flickering that resulted after a system software update on August 28, 2013
(Case ID 498560320 - not much help came from Apple Support but fortunately the problem went away a week later after another system software update)
• A case of battery failure that resulted after a system software update on October 11, 2013
(Case ID 516534003 - I have gone through all recommendations from Apple support as I will detail below)
Symptoms after system software update
• Battery Icon on status bar disabled with a message "No batteries available"
• Battery not charging
• LED on the Magsafe power adapter no longer show
• Keyboard backlights no longer show
• Notebook fan loud/noisy and permanently at high speed
• Date and time reset to a date in the past at each restart
• Notebook starts up the moment the Magsafe adapter is connected without waiting for power button to be pressed
• An update for "MacBook Pro Retina Display SMC Update 1.2" keeps appearing in Software Update
Recommendations from Apple Support
• Perform SMC Reset (http://support.apple.com/kb/HT3964)
(Done - no change in status)
• Run Disk Utility
(Done - no errors found)
• Run Apple Hardware test (http://support.apple.com/kb/HT1509)
(Done - no errors found, no change in status)
• Visit Apple Store
(Done - they confirmed no issue with Magsafe adapter. For a fee they are happy to change the battery if confirmed faulty and re-install the OS if the battery is not the issue but am uncertain that the OS re-install will resolve the issue because I have read online about a similar case where a re-install did not resolve the issue)
• Check System Report/Hardware/Power
(Done - Health Information/Cycle count:0, Battery installed: No)
• Perform NVRAM Reset (http://support.apple.com/kb/HT1379?viewlocale=en_US)
(Done - no change in status)
Comments and additional Observations
Please note the following;
• All of the symptoms above appeared after a system software update on October 11, 2013
• This update first appeared on October 10, 2013 but I was too busy to apply it especially because it required a system restart
• The battery was fully charged when I decided to apply the update on October 11 morning after I got to work
• Normally on full charge, the battery will typically deliver 3 - 4 hours depending on usage and up to 6 hours when idle
• The said update was not interrupted or anything of the sort
• On the day the symptoms were first observed when I first logged the case with apple, the system ran on battery while it performed the Apple Hardware Test while I was driving to the Apple support store on my way home even though the status bar was indicating "No battery available"
I make the following deductions solely based on my observations
• An apple authorized system software update broke the system
• The nature of the failure is communication related - the battery charging circuit and related systems are not getting the necessary instructions to function as they should (It's a known fact that rechargeable batteries do NOT die instantaneously, the total hours they run on full charge will gradually reduce over time as they degrade on use)
• It’s possible the update is not being applied correctly because the item “MacBook Pro Retina Display SMC Update 1.2” is still in Software update after subsequent attempts to apply it
• The high fan speed is nothing to do with high temperature or high processor load, according to the Activity Monitor utility the highest CPU utilization 1.9 – 4.7% is by kernel_task (PID 0) followed by activitymonitord at 1.8 – 2.2% (PID 481)
• The symptoms match what an SMC reset should resolve according to Apple documentation
• This is a known problem within Apple based on the documentation provided and the numerous similar cases reported online
Summary;
The system is running OS X 10.8.5
I have provided this detailed documentation in the hope that someone who understands this system can say exactly what is going on. It's meant to be a dream machine but now you can hear the fan from across a large room, the battery doesn't charge and is in fact not recognized so I lose data if the Magsafe adapter gets unplugged, and I have to reset the system date each time I restart the notebook.
I've used this notebook with utmost care for a little more than a year, this investment of over $3,500 could have bought 3 high end notebooks from DELL or HP but I chose Apple.
I have suffered untold loss in productivity in the last 10 days since this issue occurred, I respectfully request Apple to fix my notebook.

Macbook Pro Batterie suddenly dies !

Hey,
as others reported my Macbook Pro 17" also died yesterday !
I just worked like I normally do and had about 80 % batterie life and then suddenly the Macbook Pro was off. No shutdown, no warning just stopped working ! I pressed the power button, the start sound came I saw the Apple and again it turned itself of, just like if you run on power cord only and suddenly remove the power cord. I tried again and it also turned itself of even before the grey apple appears. So I removed the batterie for about 10 sec. put it back in and ... now it is working for the moment. But what the **** was that ? Any explanation ? It happened between 92 % and 83 %.
About my Macbook Pro:
I have it for about 15 month and use it everyday and really like it cause of the ability to run workstation tasks on the street, but this batterie issue really argues with me.
Battery Information:
Model Information:
Serial Number: SMP-ASMB014-XXXX-XXX //I changed that !
Manufacturer: SMP
Device name: ASMB014
Pack Lot Code: 0001
PCB Lot Code: 0000
Firmware Version: 0102
Hardware Revision: 0202
Cell Revision: 0100
Charge Information:
Charge remaining (mAh): 4427
Fully charged: No
Charging: No
Full charge capacity (mAh): 5696
Health Information:
Cycle count: 505
Battery health: Good
Battery Installed: Yes
Amperage (mA): -2499
Voltage (mV): 11451
Any idea ? I am not sure if similar things happen again if I reach about 85 % of batterie, but I guess so. Therefore please help and tell me what to do, I have no idea. I am going to run to 0 % to re-calibrate the battery and hope that works but other ways ... . Never saw a battery stop working that suddenly.

I did the power management reset and now the numbers changed:
Model Information:
Serial Number: SMP-ASMB014-XXXX-XXX // I changed that !
Manufacturer: SMP
Device name: ASMB014
Pack Lot Code: 0001
PCB Lot Code: 0000
Firmware Version: 0102
Hardware Revision: 0202

Charge Information:

Full charge capacity (mAh): 3858
Health Information:
Cycle count: 506
Battery health: Good
Battery Installed: Yes
Amperage (mA): 3320
Voltage (mV): 11905
And istat also say only 61 % health left, that seems to be more realistic. I hope the battery now stops shuting down my Macbook Pro.
