Plugging and unplugging power supply

Can anyone tell me if there is a risk to the hard drive by plugging and unplugging the power supply while the compter is on- like if, let's say, I unplug from the power supply in my office to use my laptop in another room?

None at all.

My battery will not charge when plugged in to power supply. What's up??

I recently purchased a new MacBook Pro from my college, and have barely had it two months. One morning I started it up and it would not hold a charge. It will not remain on unless it is plugged into the power supply. If I unplug it while it's on it immediately shuts down.
Sometimes if it's plugged into the power supply for a while it will shut itself down un-announced.
I'm very frustrated, mostly because I just bought it and had Snow Leopard installed and everything. The message on my battery status simply says (Not Charging), though the icon says it's fully charged, and the light on the power supply is green. I'm very confused.
Any idea what's going on and how I can fix it? Is the battery simply not connecting, or is it shot already?

As the original post stated, "One morning I started it up and it would not hold a charge. It will not remain on unless it is plugged into the power supply. If I unplug it while it's on it immediately shuts down."
This is exactly what's happened to mine this morning. Last night everything is fine, remember seeing about 5 hrs remaining on the battery, plug it up but this morning will not remain on unless its plugged in. If I unplug it, it immediately shuts down.
My first thought was somehow I didn't plug it up or there was something wrong with the plug itself and the battery was drained but then I realized its working with the power cord so that's not the problem, only when on the battery.
How can a battery just crap out overnight???

If plugged into the power supply, should the Cinema Display A1081 standby light come on without being plugged into a mac

I was given an old Cinema Display A1081 a few years ago. I am trying to test it and want to know if plugged into the power supply, should the standby light come on without being plugged into a mac? I don't want to buy a DVI to mini display adapter if it isn't working. One thing I did do was plug Monitor power in and then the USB plulg into my PC laptop and my iPhone charger USB plug into the back of the monitor. I am able to charge my iPhone this way so I know that the power supply is working. But I can't tell if the monitor itself is workign as no ligths are on. (PS: I am purchasing my first Mac so I am a complete newb but very proficient with PCs) Thanks so much for your help.

Just a final question about Sleep mode - does this have any negative effects on the life or performance of the laptop? I'm so used to Shutting down the laptop each day that I worry about Sleep mode having some sort of drain on the components or something.
There are only two practical differences between Sleep and Shut Down:
1. Sleep will wake instantly, so you don't have to wait for startup.
2. Sleep will drain a new, fully charged battery after several days without being woken or plugged in. If you shut down, the battery charge lasts much longer. Obviously, if you only sleep it overnight, you'll still have plenty of battery left in the morning.
Don't sleep it more frequently than necessary, though. Frequently turning the backlight and hard drive off and on can shorten their life. Just do what's reasonable. I usually leave mine awake until I have to transport it in a bag, along with sleeping it overnight. On battery, I'll sleep it more often to preserve battery.

The light on my apple tv is blinking furiously. i've held down the menu button, plugged and unplugged it, and just tried restoring it via micro usb. but the restore downloads then says it can't finish because it can't write to the disc. lost lost

Hi lostinmedford,
Welcome to the Apple Support Communities!
I understand that the light is quickly flashing on your Apple TV and you are unable to restore it. According to the attached article, you are working through the correct steps by trying to reset and restore the Apple TV. In this situation, if the restore did not resolve the issue, it may be necessary to have the Apple TV evaluated for service by using the link in the attached article.
Apple TV: About the status light - Apple Support
Flashes quickly
Having issues. Try restarting or waking your Apple TV. If your Apple TV does not start up properly, you might need to reset the Apple TV or restore it to factory settings.

HOW TO GET MY IPHONE 4S OUT OF BEING STUCK IN HEADPHONES MODE? I TRIED BLOWING IT, I TRIED SUCKING IT AND I TRIED THE QU TIP, ALSO FREEZING AND PLUGGING AND UNPLUGGING THE HEADPHONES. I ALSO RESTORED IT AND PUT IT IN DFU MODE AND STILL NOTHING.

How do i get my iphone 4s out of being stuck in headphones mode. When i dont even have headphones plugged in, it says headphones ringer. I've tried blowing and sucking in the jack, didnt work. I tried using a blowdrier in the jack, didn't work. I also tried putting it in the freezer while in a plastic bag, trying to clean it with a qu tip, and plugging and unplugging the headphones more than 100 times, still nothing and i also restored, reset, and put my iphone in DFU mode, and still nothing seems to work. DOES ANYONE KNOW ANY OTHER WAY I NEED HELP PLEASEEEEEEEE!!!!!!!!!!! ANYONE ANY OTHER WAYS TO FIX IT?!?!??!? That would be very helpful

I had the same problem. I squirted a drop of WD40 in the headphone hole and then used a plastic dental toothpick and twisted it around in the hole. It amazingly worked.
Good luck

Why do I have to have my phone plugged into a power supply to sync wirelessly?

What is the point in being able to sync wirelessly if I still have to have my phone plugged into a power supply? If I have to plug it into the wall, I may as well plug it into my Mac. That's pointless.

Yes, I realize that, but that pretty much makes the wireless sync pointless. You know what I mean? If I have to plug it in to anything I might as well plug it into my Mac

TS1574 you should mention that the audio output jack is fleaky, try plugging and unplugging until red light goes off !!!

It should be mentionned in the Apple help that the audio output jack is sometimes fleaky, as it does not reclose the speakers contacts correctly when an earphone jack is removed. This can be checked by looking into the computer audio jack and seeing a red light, which confirms the optic output is active. Plugging and unplugging the jack until the red light disapears is the cure, unless you are unfortunate enough to have a broken audio jack. Good luck !

Same here. I don't remember doing anything out of the ordinary. I was working in Parallels on getting a AM station to stream via some web interface. Next time I went to play sound on the internal speakers, no go.
I've tried zapping the PRAM, toggling the headphone jack and the toothpick thing. Nothing seems to work.
I've also noticed that I get sound in my headphones in iTunes but not in Garageband (someone had suggested that starting up Garageband would reset things.
Any other ideas out there?
Is there a file that could get corrupted that I could switch out of my back up?

Macbook stuck in headphone (optical digital-out port) mode. Plugging and unplugging headphone jack no help.

Stuck in headphone (optical digital-out port) mode. What do I do? Plugging and unplugging headphone jack no help.

Do you see a red light in the headphone jack?? If you do, then the microswitch is stuck and you need to turn it off. Try poking it with a toothpick.
If you don't see a red light, then try resetting the SMC and PRAM and see if these helps. Here are the links.

Plugging and unplugging earbuds with car bluetooth

I just bought a new iPhone 5C running 7.0.4 and paired it with my Honda's bluetooth for handsfree calling. The problem is that if I start the car while listening to itunes with my earbuds as soon as the car pairs I can't hear my music anymore. I have to plug and unplug my ear buds to get audio back through the buds. The handsfree phone works great. Are there any settings I'm missing? Unplugging is a bit of a pain. Any help would be appreciated.

That's because the car supports A2DP audio streaming. As soon as it makes the connection, it switches to the bluetooth audio streaming. Turn your stereo on and switch to the proper input. You should hear the music on your stereo.

I just bought an ipod touch 4th generation recently,found that it is very difficult to plug and unplug the USB cable from my ipod.Does anyone have this problem?

I just bought an ipod touch 4th generation recently, found that it is very difficult to plug and unplug the USB cable from my ipod. Does anyone have this problem?

Some of the Dock connector cables have very small buttons on the rounded adge of the plug, which need to be pushed in to release the plug from the iPod. Look at the picture below, do you notice the "button" on the white connector edge? There's one on the other edge too and they both need to be pressed in to release the "evil looking spike" sticking out of the grey edge.
The shorter plugs (that I've seen) do not have the release mechanism, the plug simply pulls out.

Is it safe to plug and unplug USB and Firewire cables with the computer on?

Is it safe to plug and unplug USB and Firewire cables with the computers on? I have a Mac G4 and a newly purchased IMac and I use one printer for both computers. Should I shut down the computers when I unplug the printer and connect to the other computer? How about when switching firewire drives.
Is there an easy way to have both computers connected to the same printer? I have an Epson 1280 printer.

Yes, you can unplug a printer without shutting down the computer, but if you are switching the printer to another computer then you should first turn off the printer, unplug it, re-connect to the other computer, then turn on the printer. This will assure that the printer will be properly recognized.
If you have your computers networked via Ethernet then you can leave the printer connected to one computer and share it with the other via the network connection. Printer sharing is turned on using the Sharing preference in System Preferences. You will need to Add the printer on both computers so you will need the appropriate printer driver installed on both computers.

USB/Firewire ports were designed to be "hot" plugged. You can safely plug and unplug devices without usually having to shut down the computer or the device. Some devices, such as external HDs, digital cameras and iPods need to be "ejected" first, so as not to damage their formatting or data.
You can network your Macs wirelessly or with an ethernet cable and then set the printer connected to one computer to be shared with the other computer.

I have an iPhone 4S that won't charge. I have tried with 5 different cords and 2 wall plug but it won't connect. It will work if I plug and unplug my phone for 20 minutes. Please help me!

Clean out the charging port--make sure there's no dust or debris in there. If that fails to solve the issue, bring the phone to Apple for evaluation.
