Is it ok to continue plugging in a rMBP to ac when its sleeping? (When the battery is already 100%.)
Using my rmpb mainly as a desktop. Been searching around online and found that it is ok to plug in to ac constantly (with occasinal cycles). But what about when it is sleeping? Does that make a difference? Have read somewhere that says its not good to plug in to ac when sleeping ._.
Thanks!
The computer isn't harmed by being plugged in while asleep. However Apple does recommend that you take the computer off the power adaptor at least once a month. You don't want to drain the battery. When your battery is about 80% depleted you should get a warning that you are on reserve power. At that point plug it back in.
Since my office MBP sometimes sits on my desk for weeks, I've set a repeating monthly reminder so at least once a month it gets used on battery. This is a 2009 MBP and the health is excellent.

Should I disconnect the charger once the battery is 100% full. Or can I use the laptop plugged even when the battery is full., Should I disconnect the charger once the battery is 100% full. Or can I use the laptop plugged even when the battery is full.
You can leave the charger plugged in, as you cannot overcharge...charging automatically stops when your battery is full. Once every 2 ~ 3 months, its a good idea to drain the battery to about ~ 40%, then recharge to full. Otherwise, you can charge whenever you like & leave connected whenever you like.
Try to avoid full battery discharges, Lithium batteries don't like that & frequent full discharge/recharge cycles will eventually kill your battery. -
i dropped my ipod in water ... the backlight will come on when the battery is dead and i plug it in .. but when it is on the home screen it won't come on
After drying the iPod in a sealed container od uncooked rice for a week with changing the rice daily, try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that indicates a hardware problem likely caused by the water. -
My iPhone 5 with iOS 6.1.3 keeps crashing at 45%!when my iPhone nears 45% from a full charge it suddenly says the phone is 20% then 10% then 1% and then it goes dead.when I plug in the charger instead of waitin a few minutes for it to turn on,it instantly turns on and says the battery is 45%!this is OK at home where I can keep the charger plugged in but what about when im on the go?PLEASE HELP!!!
This is most likely faulty battery. Make Genius reservation or set up service and take or send to Apple for resolution under Warranty.

will it be possible to save the data when getting repaired???Hello there stidhambr15,
I was researching the issue you are having and recommend a couple of things. First it might be a good idea to reset the device following iPhone, iPad, iPod touch: Turning off and on (restarting) and resetting found here http://support.apple.com/kb/ht1430
Resetting your device
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
If that doesn't quite get the device going again, I recommend restoring the device.

Might even be a good idea to turn off the phone, reseat the SIM card, and turn it back on.

HT4060 I have my iPad plugged into the wall, how come its not charging the battery?
How come my battery is not charging even though the iPad is plugged in?
The possible reasons could be....
1. Bad connector cable
2. Faulty power adapter/charger
3. Problem with the wall socket
4. Faulty dock connector opening
5. Something impeding the charge getting through - debris in the connector end of the iPad
6. Faulty iPad/corrupt software
Try another cable, another power adapter, another wall socket, and go from there. Nobody can just guess what the reason is, start eliminating some of the possible causes and go from there. -
So for about 3 weeks, I have been forcing my macbook to close because whenever I wake it from sleeping to use it, I try to put in my password but it blacks out. I finally figured out that this only happens when its plugged in and near full battery life. Does anyone else have an issue similar to this?

The battery drained while using the computor so we pluged it in but computor will still not fully turn on.
Welcome to the Apple Support Communities
Hold the Power button for about 5 seconds to turn off the Mac (it may be turned on), and then, press it again. If it doesn't work, reset the SMC > http://support.apple.com/kb/HT3964
If nothing works, take the Mac to an Apple Store or reseller to get your computer repaired. Also, if you have its charger connected to the computer, is the charger light turned on? -
HT3205 My adapter plug light is orange - won't stay green to charge the battery. What is the cause?
My adapter light does not stay green to indicate the macbook is charging. The light turns from green to orange after about 5 seconds. Why is my battery not charging?
1. SMC reset
>>Instructions to reset SMC
Problems solved: Fans blowing with no activity, machine is not booting, power button pressed and nothing happens, problems with indicators, Magsafe has wrong lights, battery is not charging, monitor and graphics issues etc. If the battery is not charged (from like letting it sleep too long), let the Mac charge up awhile afterwards.
Will not hurt the machine resetting if it's not broken.
Other related hardware problems (optional):
Check battery status: Hold option/alt key down while clicking on the battery icon in the menu bar, top right corner.
Magsafe: Use the correct/matching power supply charger with your Mac, not a less powered one from another Mac.

Why does my macbook only turn on when the power adapter is plugged in?
The battery life says its at 73% and climbing but whenever I unplug my power adapter the mac automatically shuts down and if I try to turn on the macbook without my power adapter plugged in, it wont turn on. How do I make it go back to where I can turn the mac on without it being plugged in? Thank you for your help!
I would try two things the first being resetting the System Management Controller:
1) If the computer is on, turn it off.
2) Disconnect the AC Adapter and remove the computer's battery.
3) Press and hold down the power button for 5 seconds and then release the button.
4) Reconnect the battery and AC Adapter.
5) Press the Power button to restart the computer.
If that doesn't work I would recalibrate the battery.
To calibrate the battery:
1) Plug in the MagSafe power adapter and fully charge the MacBook or MacBook Pro battery until the light on the MagSafe connector changes to green and the Battery icon in the menu bar indicates that the battery is fully charged.
2) Allow the battery to rest in the fully charged state for two hours or longer. You may use your computer during this time as long as the power adapter is plugged in.
3) Disconnect the power adapter with the computer on and start using it with battery power. When the battery's charge gets low, you’ll see the low battery warning dialog on the screen.
4) Continue to keep your computer turned on until it goes to sleep. Save your work and close all applications when the battery's charge gets low and before the computer goes to sleep.
5) Turn off the computer or allow it to sleep for five hours or longer.
6) Reconnect the power adapter and leave it connected until the battery is fully charged. You may use your computer during this time. -
Is it advisable to use your i Pad plugged into an electrical outlet rather than the Battery in use?
Is it advisable to use your iPad plugged into and electrical outlet rather than using the battery all the time?
I use my iPad while it is plugged in and I use it on battery power as well.
I use my iPad all day long at work on battery power and then come home and plug it to recharge. Typically I will use it the rest of the night while its plugged in. When the battery is fully charged, the charging process stops and you can continue to use it while it is plugged in and it will not overcharge.
It will not hurt to use it while it is plugged in, but the beauty of having a better powered device is that it is mobile and you don't have to plug it in to be able to use it virtually all day long. -
Headphones only work if already plugged in when the Mac is turned on
I have a 13” mid-2012 MacBook Air running Mountain Lion. I recently noticed this problem with headphones. If I plug them in when the laptop is already running, they don’t work at all. Sound continues to play through the speakers, and the OS doesn’t recognize that headphones were plugged in. If I go to Sound on the System Preferences, the headphones don’t show up at all on the list of output devices; only the integrated speakers show up. If I alt-click on the sound icon on the top bar, there are no headphones listed under output devices either. The sound continues to play normally through the speakers as if the headphones weren’t plugged in. However, if I plug in the headphones when the machine is turned off, and then turn it on, they work perfectly (well, sound quality isn’t great, but they work). If I then unplug the headphones and plug them back in, they don’t work anymore as described above. I tested this with multiple headphones, all of which work normally on other devices like my PC, iPod and Android phone. I tried resetting PRAM and that other thing (SNC?), didn’t work either. I don’t think it’s a hardware problem, since it works normally under specific conditions. Sounds more like a software bug, but I’m no expert.. I searched around for issues like this, but only found generic answers which didn’t solve the problem, as well as unanswered posts
Since this is a consistant and repeatable issue, take it in to your nearest Apple store genius bar for evaluation. If you are still under warranty, they should fix the problem.

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.
