Battery and 3.1

I recall reading that 3.1 was going to help prolong battery life. Does 3.1 help? I also recall Apple advertising better battery life. Any truth to this?

Not sure where you read this, but I don't believe Apple released any information regarding what would be included with firmware update 3.1 before it was released.

If you have records that show that you've taken your MacBook Pro in for a year to fix the machine, I would escalate the problem to Apple Customer Relations - unfortunately I don't have a number for Spain.
It would only seem logical to me that if you've been trying to have the machine repaired during the time that the 'recall' was in effect that you should be eligible for a new logic board. But only customer relations will be able to make that call.
Good luck - take the issue as high up the food chain as you can and see what happens.

Battery and power issues in T43

Hi!
I have a 2005 Think pad T43, that for the last month won't charge the battery. It is connected and the battery indicator light is on, but the battery keeps going down when plugged in to AC adapter. It was able to charge when I reset the battery soon after I first noticed this problem, but after that was finished, the problem remains. I then proceeded to use my computer with the battery removed and connected to the AC adapter. This worked for about 2-3 weeks until it suddenly turned off without warning. I turned it back on, it started to boot, then turned off again. I tried putting the battery back in, which succeeded in booting my computer, but then the battery died. I tried taking out the battery, unpluging it, and holding down the power button, but that did not help. My computer would turn on for a few seconds each time I turned it on, then would turn off. Now, it won't turn on at all, not even an indicator light. When the battery is in and it is plugged in, the battery indicator light is on. My battery and AC adapter are about a year old.
I really don't want to buy a new computer but realize I might have to if I can't inexpensively fix this one. Any help or advice would be much appreciated.

Battery and Magsafe issues

I've had my Macbook for about 9 months and I am having issues with the magsafe and battery. If I try to run the computer without the battery installed it shuts down the first time it tries to access the HDD or requires even light use of the processor. In turn, whenever the compuer is plugged in, the battery charge hovers at about 95% and is constantly charging. As a result of this, the battery stops working at about 50% charge (The computer just dies mid-task and never goes to sleep) even though my cycle count is only 174. If I were to bring the computer in, could they replace the battery and magsafe since I am still under warranty?

Seems I failed to read your post carefully the first time - apologies!
First off, try resetting the SMC:
http://docs.info.apple.com/article.html?artnum=303319
If that fails to correct the problems, then you will need to contact AppleCare (or make a genius bar appointment and bring it into an Apple Store). It may be as "simple" as battery+charger, and they may start there, but it may also be an internal hardware issue. It's definitely a hardware issue, though, so you're covered under warranty.

My ipod 60gb classic is showing as fully charged until I connect it to my pc when it comes up with the error message, 'please wait very low battery' and the little wheel goes round and nothing happens, can anyone explain why this is and what i can do?

I have worked my way through the assistant and nothing works. I have tried connecting in disc mode but although the screen on the ipod is showing that the device is charged and that it is in disc mode as soon as I connect it to the computer it comes up with the error message 'please wait very low battery' and stays like that until I disconnect when it appears to be OK again. I have tried on both pc and mac.
BTW the ipod is an ipod video not classic if that makes any difference.
Thanks

Why is my iPhone 4s stuck on 8% battery and why will it not restart for 12 hours when it dies?

I've had my iPhone 4s for almost 2 years now and the only thing I've had done was my battery and charging port replaced about 9 months ago.About a month ago, I noticed the battery indicator was jumping around when I looked at it, then it just stayed stuck on 26% until it I accidently let it die one day. I tried to plug it in to several chargers, but it kept flashing the apple symbol and going black. I tried a charger with a 2.1amp plug in and discovered that the phone turned on, but it will only stay on for 5 minutes or so then it freezes and dies, also, every time it turns back on it shows the correct battery % for that time. So when I leave it plugged in for about 12 hours(possibly when it gets over 50% charged?), it will stay on and I've been using it like that for a month, without the proper battery indication and only able to charge on one specific charger. It's a 16gig, so it's close to full and I'm not sure if that has anything to do with it or not. People have said it may be the battery or some kind of ground that is missing, but I really don't know. Any advice?

I have this same issue... the phone was fine, then 3 days ago then I noticed it was draining itself whilst on charge. Now it charges to 1% and lasts all day on that unless I reboot, then it just says plug it in and wont reboot! I have had a 100% charge, but it drained down to 9% in under an hour and then stayed at 9% all day. This is obviously an issue, so why is Apple not sorting it out?
Also, these kind of comments (BELOW) are about as useful as, "is it plugged in?"
"diesel vdub Atlanta, GA
Basic troubleshooting from the User's Guide is reset, restart, restore.
Try each of these in order until the issue is resolved."
I have tried 3 cables, 2 wall chargers and 2 docks, so it has nothing to do with those. I have cleaned the connections, so it's not dirt. It isn't water damage as the phone has been nowhere near water.

My phone is lost. When I use "find my phone", it says that my phone is "offline". It has a charged battery and I hadn't turned it off.

My phone is lost. When I use "find my phone", it says that my phone is "offline". It has a charged battery and I hadn't turned it off. When I call my number it immediately goes to the voice mail. Does that mean someone has found it and turned it off? What should I be doing. I have used icloud to lock and send a message to my phone but if it is offline does that do anything? HELP!!

Welcome to the Apple Community.
It may be that someone has turned it off or it may be that it has been lost in an area where there is no reception. The best thing that you can do, is contact your provider and let them know that you have lost your phone, and change your iCloud password at My Apple ID

Waking from sleep with no battery and no keyboard action

Hi there,
Since this unfortunate battery recall, I'm now running my PB with no battery (as recommended) i.e. just the power supply. I have my PB configured to prompt for a password when waking from sleep, which it does. However my keyboard does not appear to be responsive for several seconds.
Here are my steps:
1. Close the lid. PB goes to sleep.
2. Open the lid. PB wakes up and prompts me for my password.
The mouse cursor via the trackpad is responsive immediately. However attemping to type in the password field does not yield anything. The PB then automatically goes back to sleep. I can then wake it again with the keyboard and start typing.
The really weird thing is that with the battery installed, I do not have this keyboard issue i.e. my keyboard input is accepted immediately on the first wake up.
I have reset PRAM but to no avail. Any ideas? I'd rather not live with this behaviour while I'm waiting for my new battery.
Kind regards,
Christopher

Hi Chris,
You will be pleased to know your not the only one experiencing this issue. Like yourself I am now running my Powerbook without the battery and have noticed that when waking from sleep both my keyboard and mouse are unresponsive for several seconds.
This also happened to my friends 867Mhz Powerbook when he was having battery problems. It would seem they just dont like being run without batteries installed.

Toshiba portege model A605-P200 won't POST bios unless I take out the battery and put it in again

toshiba portege model A605-P200 won't POST bios unless I take out the battery and put it in again
though, at times, it will, generally all i get is a flashing cursor NO toshiba splash screen. this seems to have started as an unsucessful windows update
i am getting driver freezing at crc.disk.exe when i safe boot when i get the machine to boot past the bios
thanks

Unfortunately, it sounds like it might require servicing.

My battery needs service as it is not working for long. Apple claims it is not a defective battery and that it is my fault since I had the computer for 2 1/2 years and have only run the battery down to empty 100 times. It is my fault because I did no

Con't
Apple claims that because I did not drain my battery frequently and kept it plugged in for extended periods of time, that it is my fault the battery is failing. I disagree because I was not ever told to consistently drain my battery before recharging or not to keep it on and plugs in for extended periods of time. I do keep my desktop computer on most of the time and that is why I have kept my Macbook air on for extended time periods. I feel that Applecare should cover this battey issue and not charge me for replacing the battey. I feel I should have been told to not keep my computer consistently running on with poweror the battery will fail. Has anyone had this problem? Apple should replace my battery under Apple care as my battery does not keep a charge anymore.
I'll wait to hear.

You said---Apple claims that because I did not drain my battery frequently
You said--- I was not ever told to consistently drain my battery before recharging
You should never do that on purpose, whoever told you that had it wrong or you misunderstood something
Sure you dont have that backwards? thats exactly what you DONT want to do.
Did you often drain the battery very low? that would explain a lot.
Someone might have been misinformed about "battery calibration" regarding much older Macs with removable batteries (see bottom)
You said-----I do keep my desktop computer on most of the time and that is why I have kept my Macbook air on for extended time periods.
thats a problem there, youre not supposed to do that.
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%.
http://www.apple.com/batteries/notebooks.html
"Apple does not recommend leaving your portable plugged in all the time."
*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.)
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.
And best "tip" is if its near a socket,...plug it in as long as you can (especially at home) since cycle count on the battery are the "miles that wear out the tires (battery)", however again, not plugged in all or most of 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
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.
From Apple on batteries:

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
Battery calibration, battery memory, battery overcharging, battery training, …all these concepts are mostly holdovers from much older battery technology, and on older Apple portable Macbooks ranging from early nicads, NiMh and otherwise; and these practices do not apply to your lithium battery and its smart controllers.
Calibrating the battery on older Apple portable Macbooks with removable batteries.
http://support.apple.com/kb/PH14087
There is no calibration of current Apple portable Macbooks with built-in batteries.
http://support.apple.com/ht1490
There is no battery calibration with current Apple portable Macbooks with built-in batteries. Lithium batteries have essentially a 0-‘memory’, and all such calibration involve the estimations fed to the system controller on the SOC (state of charge) of the battery over long periods of time as the battery degrades. The software based battery controller knows the battery's characteristics, or SOC and adjusts itself. This is why there is both no need and purpose to periodically deeply drain your macbook battery, since it doesn’t affect the characteristics of the battery, and further still deep discharges are something you should not do on purpose to any lithium battery.

I have a ipod mini, i upgraded my battery, and drive to 32 GB, my itunes will not see it, and the mini only shows file pic error. I have a 10.4.11 powerbook 667 so i can't upgrade to a newer itunes, which is 4.7.1, all i want is a better battery-more song

Hi,
I have a older ipod mini which needed a battery, so i also upgraded the drive to a 32 GB flash drive. When i did the upgrade, it saw the itunes fine, but it never loaded anything. When i unplug it it shows the folder with "!" icon, and i can't get my itunes to see it. I have a powerbook 667 mhz g4 with itunes 10.4.11, so i can't upgrade to leopard. All i wanted was a better battery and a bit more song volume. This older 4 GB will fit back in and works fine, but i'm upset i spent $37 to only fail. What am i doing wrong? itunes is 4.7.1 How can i over come this?

In Disk Utility, select the iPod (the device) in the sidebar. So, if you see the iPod in the sidbar with a "volume" indented below the iPod, select the "device" (not the volume).
Go to the Erase tab to the right. The choice for Format is Mac OS Extended (Journaled). Name does not matter, because iTunes will rename it during the Restore. Click Erase.
it "flashed" out of itunes.
That may be an issue with the USB connection. As a test, shut down (power off) the Mac. Disconnect other USB devices including USB hub, except for standard USB keyboard and mouse (if normally used). SInce this is a laptop, connect it to its power adapter, so that it's not running on battery power.
Connect the iPod to a direct USB port on the Mac. Note if there is any difference regarding the iPod not maintaining a connection.

i try to reset but nothing happened. & my warranty had end bcause i bought thru small dealer with a month's shop warranty only. due to problem of getting hot of the iphone's right side body, is it may cause of battery problem? how much will it cost to solve/repair this kind of problem?
thank you for ur help earlier
