Can batttery be bypassed? do i have to unplug and plug into wall always?
hi, im looking at buying a macbook or macbook pro.
when i plug in the power adaptor to the wall socket,
the battery gets charged right?
isnt there a way to NOT use the battery, and so just draw
power from the wall socket?
cause mostly the laptop will be stationary in my room, with
music devives connected to it............will i have to unplug the adaptor
when the battery is full? or can i leave the adaptor plugged into the wall ALL THE TIME? .........do i HAVE TO unlug and plug the adaptor in accordingly to battery level????
if i take the battery out, and just plug into the wall, will this work???
thanks
Hi,
I'll second that opinion. MacBook Pro has a lithium ion technoogy battery that tolerates charging even when not fully discharged. There is a smart charge regulator in the battery pack itself that prevents over-charge. It is safe to leave the battery in the MacBook Pro and connect to wall power when convenient.
The typical number of charge/discharge cycles for the battery pack is around 300 to 500. The battery pack will gradually lose capacity as it ages.
Also it helpful to recalibrate the battery once in a while. Calibration gets the smart charge regulator back in sync with the actual capacity of the battery. Basically, calibration is using the computer until the computer wants to shut off because the battery charge is depleted. Then, fully charge the battery. The regulator will then figure out the actual working capacity of the battery. Calibrating assures the battery indicator in the menu bar shows an accurate estimated capacity.

Why is my extreme losing power while plugged into the wall? I have to unplug and plug back in.
My extreme loses electric power while plugged in. I have to unplug and plug back in. This has happend 2 times in 1 week.
It might help to clarify the conversation here, if we knew what version of the AirPort Extreme that you were using.
Do you have the newer "tower" version of the AirPort, which uses a regular AC power cord......or......do you have a previous model that is "flat or square" shaped, that utilizes both an AC power cord and a separate, outboard power supply that plugs into the AirPort Extreme?
Approximately, how old is the AirPort Extreme? If you could look on the bottom of the AirPort Extreme. then locate and post back with the model number of your AirPort, we'll know even more. The model number starts with an "A" followed by four numbers. -
When I plug in iPhone (5.1.1) to computer, playlists show up on the iPhone (when plugged in), that do not appear when it is not plugged in. And I can't erase them. I have iTunes match, and deleted all my music on the iPhone, but that had no effect on the phantom playlist that shows up on the PC when I plug in the iPhone to the PC. I cannot manually move songs or playlists from the PC to the iPhone
Help greatly appreciated.Unplug your Iphone out of your computer and replug it back in. It took me several times before I could do this

Apple does not repair devices beyond replacing the screen on some models or a battery replacement. They replace the ENTIRE device.
For the Out of Warranty replacement cost, you could have gotten a fully functional replacement device. Instead you chose to spend less to get only the screen replaced and continue to live with additional issues.
Apple will not touch the device now. They will know that it was opened elsewhere and that the replacement screen is not original. -

You do. Your system is either Windows or Mac (or maybe a couple of other less popular choices) and a version of one or the other.
When you set up your machine, you were asked for an administrator user name and password. You need both of these to install software. -
iTunes says I have over 9GB free but when I sync it says I can't as i don't have enough storage and need another 1.3GB! it's driving me mad!! help!!
Check carefully. Perhaps you are trying to copy 9 GB plus 1.3 GB for a total of 10.3 GB. That would give you the message you see.

I have a Power Mac G4 double mirrored model and everytime I shut it off it will not go on when I hit the power on/off button again. However, if I unplug and plug in the power cord it boots fine and everything is OK. The PMU and logic board have been reset. Sometimes my Mac goes on just by pressing the power on button but most times I have to pull the power cord and put it back in. Any ideas or help out there for this? Could it be a failing power supply? Apple Care says that this model is obsolete so there is no help from there. John
<E-mail Edited by Host>Hi John,
That's often a sign of a bsad Capacitor in the Power Supply, but...
Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & can cause strange startup problems...

Woke up to my iPhone 4 being completely blank. I've tried restarting and resetting it as well as charging it and plugging into my computer. Can anyone shed some light as to what may be wrong or how to fix it? Thanks
Hello there, Kyle.Kuz.
The following Knowledge Base article that provides some helpful pointers to help resolve your issue is:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/TS2802
Specifically:
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 15 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
Thanks for reaching out to Apple Support Communities.

If I always have my MB Pro plugged into the power adapter. . . .
If I always have my MB Pro plugged into the power adapter, will my battery still wear out as it would if I were depleting and recharging it daily?
I tend to find a power outlet anywhere that I go in order to run my MB Pro on the adapter rather than using battery power. It's a habit that formed while using my 6 year old Powerbook G4 with about 5 minutes of battery life per full charge.
I understand that it shouldn't wear out to the same extent as running the battery down constantly, but is there still a significant effect?
Does the adapter bypass a full battery and power the computer directly?
I feel like an idiot asking this question, but I am really curious.
Thanks in advance for your responses.Various yes and no takes on it:

My ipad has the message-This ipad hasn't been backed up in two weeks. Backups happen when this ipad is plugged in, locked, and connected to wi-fi. I press ok and nothing happens. I have it locked, plugged into wall, and conected to wi-fi. How do I get it past ok?
Go to Settings, iCloud, and then Storage and Backup. You will then see a button to backup your iPad. It may be that you have much stuff (i.e. photos, apps) for it to do a full backup but you will be able to tell what the estimated backup should be and what it will consist of so that you can choose to prune down items. If you don't want to backup and get rid of the messages you can just turn backup off from this area as well.

I want to connect my iPod shuffle to a telephone line so when people are put on hold they can listen to music, however the battery will die after some time.
Can i charge the iPod whilst listening to music simultaneously? (Plugged into wall not computer)Thank you for using the Apple Support Communities
The iPod will support playback and charging only if you have a wire that supports it. Since both audio out and electricity flow through the 1 headphone port you would need a cord of some sorts that will allow the iPod to charge and include audio out. As far as using it on a telephone. If the telephone you are using supports and audio input using the headphone jack then you could use the iPod shuffle as telephone music. If not than the iPod Shuffle may not be the best tool for you.
