Is the Power Adaptor required?

I'm getting a 4gb nano and since you can update the firmware on it, is the poweer adaptor required to finish the update? The Adaptor is not included in the box and this worries me.

No, it's not required for the Nano.

Yes. You can use one of a higher wattage, just not a lower wattage.

What does the power adaptor look like?

Did Apple make any changes to the power adaptor? Is it thinner too? I am waiting a month or two for the 1.6 MBA regardless of changes.

The Mag-safe connector is physically the same. A MBP or MB adapter will physically and electronically work with the MBA. However, since the MBA's port is facing down, you will need to account for this when using an MBp or MB adapter, either by charging the MBA upside down or some other fashion.
the physical size of the MBA adapter looks smaller than the MB adapter, but this will still be unanswered until someone can compare them in person.
The power output for the different adapters are:
MBA: 45 watt
MB: 60 watt
MBP: 85 watt
You can use an MB adapter to charge an MBP, but the battery will charge very slowly.
You can use the MBP adapter to charge a MB. It will not send the full 85 watts.
Apple can not warrant or guarantee no problems when using a different adapter than intended so do this at your own risk.

The Power Adaptor's Prongs

Okay, I just bought the power adaptor you plug into the wall and then use it to power up your iPod (mine is iPod nano 4GB White English). The thing is, the "prongs" you snap out do not snap out all the way-about 45 degrees.
Now, I may be too paranoid, and not pushing hard enough, but I pushed pretty hard, and they stayed put (I do not want to break this expensive thing!).
Any tips, telling me I should just push, et cetera?
Thanks in advance.

Never mind, it was paranoia, I found out long ago. Just posting to make sure none of you get all excited.

DVD+R DL - "failed to calibrate the power level required for this media"

For the first time since owning our MBP (almost a year) I have tried to burn DVD dual layer discs. I get the error message that says the "device failed to calibrate the power level required for this media"
I have searched the web and this discussion forum and see many people have the same situation.
I am simply trying to burn 7GB of data in the finder onto my disc.
I am running 10.5.2, and have tried both Fuji and Memorex discs with no success. I am a little ****** off since the discs aren't cheap...
Do I need to get my DVD burner replaced or is this a software / media issue?
Any help very much appreciated. (& the international settings tweak that worked for some did not work in my case.)

I found the fix to this problem. I tried the trick with changing the languages and it didn't work for me. After hearing the success stories from other people using the language trick I realized that calling apple and getting my superdrive replaced won't do the trick. My superdrive burns CD and 4.7Gb DVD without any problems but when I try to burn DL it shows the message "failed to calibrate". Here's the temporary solution to the problem (it worked for me)
Create a new account
Change the language to something other than English (I speak Russian so Russian worked for me).
I know that it may not work for some of you guys but give it a shot. Hopefully Apple will fix this software bug in the next update.

Is there away around the Power adaptor icon for my ipod?

I did a factory reset on my iPod today b.c i have been having trouble syncing up the ipod using iTunes. I used the latest firmware updater from Apple btw.
So when the factory reset was complete the app told me to plug the iPod into it's power supply, but I don't have one!
Now the ipod has the Power adaptor Icon on it because it's waiting to be pluged in, is there a way around this? I'm using an Apple USB cable if that makes any difference.
Thanks, Tim

Connect the iPod to your computer with a FireWire cable if your computer has a 6-pin FireWire port, or use a car adaptor, or try the option on this page.

I unplugged the power adaptor and suddenly, my mac started beeping repeatedly like an alarm. What does this mean?

I unplugged the power adaptor and suddenly, my mac started beeping repeatedly like an alarm. My mac was fully charged and would not start up. I pressed down on the restart button to reboot it and the noise stopped.
What does this mean?

Hi, it indicates a RAM problem, (or Logic Board around the RAM).
The power on self-test resides in the ROM of the computer. This test runs whenever the computer is turned on after being fully shut down (the power-on self-test does not run if the computer is only restarted).
If a fault is detected during the test, you will not hear a normal startup chime. Instead, the system will beep as explained below. If you experience one of these beeps, you may call your Apple Authorized Service Provider for additional troubleshooting assistance.
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
5 beeps = processor is not usable
In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.
Note: In this case, a flash is considered to be 1/4 second or 250 ms or greater in length.

Using the Power Adaptor

Greetings,
When using the power adaptor should I take out the battery?
The reason why I ask this is that I use to have a Sony laptop running Windows 2000 and had continual problems with the battery not holding its charge. I was eventually told by the Sony technicians that once the battery was fully charged I should remove it from the laptop whilst running from the mains.
Thanks in advance

Hello!
You might try posting this in the appropriate Powerbook Forum. We don't know much about laptops here in the G4 Tower forum.
If you have a G4 iBook post here.

My MacBook Pro is plugged in and running on power from the power adaptor, but the battery isn't charging - what do I do?

The magnetic charger and port are clear and clean and clicking into place smoothly.
My Mac has had 2% power for the past few hours but is running on power from the power adaptor.
But the battery isn't charging - what do I do?
Thanks!

Depending on the model of MBP, buy a new battery or take it in for servicing to get a new battery. You could also try an SMC reset to see if that helps, but your symptoms don't sound like the ones normally solved by a SMC reset.

Is there suppose to be a charging light when using the power adaptor?

I just bought the power adaptor for my ipod shuffle 2nd generation. I plugged the adaptor in the wall, connected my usb line , plugged in my ipod and there is no charging light to indicated if the ipod is charging. Should there still be an amber light to let me know if the ipod is charging with the power adaptor or not?

YES! There certainly should... I have an older version Apple Power Adapter (for the iPod Photo) and it lights up my Shuffle's status light.

Fan running constant at 6200rpm only when connected to the Power Adaptor!

My fans are runing constant at at 6200 rpm, the temperature is around 50 degrees Celsius.
No other processes running in the background Activity Monitor shows around 2-3 usage after reboot.
I did a reset of the SMC.
Funny thing is, if the MacBook is not connected to the Power Adaptor, running with the battery, the fan is running at normal speed between 1500 and 3000 (depending on what programs i use) and has the same temperature at around 50 degrees.
I am sure that it is not the Power Adaptor, i have two, one at the office and one at home, and the MacBook is only loud, connected to the Power Adaptor.
3 Year Extended Waranty just run out 3 weeks ago...
Any hints or ideas which part could be broken and should be replaced?
Is there some sort of Power Management Unit?

I did a reset of the SMC (see my first post). Did not help.
Actually i did everthing you can do, including a fresh install (10.5.6) and not updating to 10.5.7 (some had problems with their fans updating to 10.5.7), also a Harware check, safe boot, etc. Did not help at all. Now running again with 10.5.7.
I was wondering if there is a actual hardware part i can replace.
My stoneaged Powerbook had some sort of a circuit board that managed the chareging of the battery, etc. This board could be replaced.
Or do i have to accept it, that my MacBook believes to be a helicopter now.

G3 iBook wakes up as soon as the power adaptor is plugged in

My sleeping iBook will wake up (even with lid closed) as soon as I plugged in the power adaptor. Also, if the power adaptor is plugged in, closing the lid won't put the iBook to sleep. Instead, the sleep light will come on for a few seconds, and then disappears and I can hear the hard disk spinning up, then the sleep light will appear again and the cycle repeats...But when I then open the lid, the iBook will then go to sleep!!!
This only happens if the iBook is in power adaptor mode. In battery mode, the iBook will sleep just fine by just closing the lid.
I repaired permissions and reset the PRAM, but to no avail. What could be wrong?

Hi Missy L,
I don't know wether reinstalling Tiger would help. It might very well be a hardware problem. Did your iBook come with a hardware test CD? In that case, start from CD (insert CD and restart while holding down the "C" key) and run the Hardware Test. Maybe it will show something. Re-installing should only be your last resort.

Is anyone else having troubles with the power adaptors going from green charge light to amber?

I have had to replace my power adaptor once before as there appeared to be a broken wire inside ..the replacement had been working fine but just recently noticed the light changing from green to amber within seconds of being connected

The light changes from green to amber whenever the System Management controller determines that the battery needs charging. The light is green, indicating a fully-charged battery, until it is determined that the battery is less than 94% charged. That determination can take a few seconds after the adapter is connected. If the charge level is found to be below 94%, charging begins, and the light turns orange (amber) to indicate that charging is taking place. None of this signifies a problem of any kind.

Wich is the best? remove the batt. when you plug the power adaptor?

what is the best procedement when you connect the macbook pro with power adaptor for long periods?
remove the battery ?
or
leave it after total charging ?
thnaks for the help

There's no reason to remove the battery. The charger stops charging the battery once the battery is fully charged. Recharging won't occur until the battery's charge level drops below 95 percent. This protects the battery from constant recharging and from overcharging.
Removing the battery also results in the CPU automatically throttling down to half-speed.

Power adaptor requirement

If I decided to buy the new iMac from the States, what power requirement would I need so it works here? Do I just need a special adaptor that connects to the male (american) power cord and my house power wall plug?
Where could I easily get one of these?

I made it from SFO to Dulles to Frankfurt on a single battery and a Xantrex pocket inverter 175. I flew United business class on a 747 with seat power.
In XP/Boot Camp
the inverter did not work while using the computer. However with the computer asleep or turned off the inverter worked to charge the battery.
In Mac OS
The inverter also worked to charge the computer while asleep or off. When in light use the inverter was flickering off and on. I can imagine that under some conditions, and with some luck it might actually work.
I used the computer for the whole trip. I recharged the computer during meal and bathroom breaks and during my Dulles layover. I mostly ran Civ4 on XP and some iTunes on MacOS. The total travel time was about 15 hrs and I arrived with about 20% power left.
