Can I use the power supply from a 1.83GHz CD mini with a new 2.53GHz mini?

Because I'm too lazy to remove the old power supply, I just want to swap out my old mini for my new one.

I did this for a month, for the same reason as you. Both power supplies are are 110 watts -- although you can double-check that, if you like.
Eventually I did make the change, I guess because I didn't want to put "new wine in old skins".

Can I swap the power supply on my iMac G5 without any unwanted side effects?

Hi All,
I'm new and have searched related posts, but have not found an answer to this exact question.
I have a first generation US version iMac G5. The label says that the power supply is 100-120V. Can I swap the power supply using an internationally rated power supply (100-240V) from a later version iMac G5 without any unwanted side effects? Such as the iMac G5 ALS power supply?
I live China and would prefer not to rely on an external power suppressor or convertor. I would prefer to plug and go.
Thanks,
SGP

Now that I upgraded to Maverick on my Mac air, I can not use the power button to shut down the computer anymore. any suggestions?

Now that I upgraded to Maverick on my Mac air, I can not use the power button to shut down the computer anymore. I now have to go to the apple icon in the upper left corner. Any short cuts instead of going to the apple in the top left corner and hitting shut down. Doing that all the time, I feel like I am back at work using a "Windows" computer.

This a is tricky one, but you can still do it. Instead of pressing the power button, hold it down for a few seconds and then you'll see the shut down options dialog pop up.
I guess they were trying to prevent accidental touching of that button. They did something similar with the Eject button a few versions ago, where you have to hold down Eject instead of just tapping it so that you don't pop out a CD by mistake.

HT4060 Can I use the power cord (30-pin and USB) that came with iPad 2 to charge it in my car's USB port?

Can I use the power cord (30-pin and USB) that came with iPad 2 to charge it in my car's USB port? Or do I need to purchase one of those cigarette lighter charging devices? Thanks!

You'd have to read your car manual but chances are it won't put out enough power for the iPad. The car is likely set up to charge a phone, most of which typically want half the power an iPad wants.
I think your options are to get a cigarette lighter looking charger, making sure it's powerful enough for an iPad...or you can get power inverters for about $25, where they plug into the cigarette lighter/power point and have a normal household type outlet on the other end. Then you'd just plug your charger in like you would at home.
Another option would be to look for something like a Zagg Sparq, which is a battery operated charger...plug the Sparq into the outlet at home. Its battery holds a charge and you can use that to charge your device. (zagg isn't the only manufacturer of such a device, Targus has one as well). Just look for portable chargers.
The key to remember is to make sure it's rated for an iPad, which will want more power than a cell phone.

How can I replace the power supply IN the time capsule

I have a TimeCapsule that has a bad powersupply. I have opened the timecapsule to confirm this. Has anyone done this before? If so, where did the power supply come from? Cost? I took this to the Apple Igneous bar and they said there is nothing that can be done about it.They said it couldn't even be opened, but simply peeling the rubber bottom off and unscrewing a number of tiny screws and that's it. The 1 TB drive is LOOSE in there. That was a bit of a surprise. I had thought that the issue was the drive itself was bad. I had hoped that if I removed that the AP part would at least work, but after opening it up and firing it up I could hear that the power supply was buzzing thus the conclusion it was the issue.
I am going to put the SATA drive in a reader to see that it is indeed ok. If that checks out, then I know for certain it is the power supply, but I don't know what to use as a sub since the unit needs both 12V and 5V. I'd just as soon find a good supply and use that. Any help would be appreciated.
Thanks,
John A Kostelac

What version is your TC.. A1xxx from the rubber foot?
Power supplies are not available from apple. They do not consider it repairable. It is a sealed consumable.
Power supplies are available from ebay.. simply type time capsule power supply into search.
This is absolutely standard issue that has been ongoing for ages and ages.
See https://sites.google.com/site/lapastenague/a-deconstruction-of-routers-and-modem s/apple-time-capsule-repair
For a multitude of ways to fix it.
The 1 TB drive is LOOSE in there.
No, it is not loose, it has rubber mounts with pins in the bottom base plate. You cannot see the mount points with the base off. This is standard hdd mount for low noise and vibration.
I had thought that the issue was the drive itself was bad.
Drives seldom are the problem. The Gen2 WD black has been less than great though.. and later spinpoint in Gen3 not so good.

Imac G5, Can I use a power supply from a G4 Q-silver (rewired connector)?

I've got a G5 Imac with a blown PS, and I'm thinking of modifying a G4 Quicksilver power supply for use as the power source for a 20" Imac G5. Yeah, I know it sounds a bit weird, but hey, I was given this Imac G5 (1st Gen. 1.8GHz) for free. It's missing the back cover, and the PS is shot. So if I blow it up it no major loss. It's a project!
I have determined that the original PS is shot and needs to be replaced. I don't really want to drop $140 for a replacement PS, as I would also have purchase the back cover for another $40 + shipping. Go figure, right? It appears that most of those power suppies tend to fail early, anyway.
During my checks of the Imac internals, I also noted that during the "power on" tests, using the old power supply, I would get the second indicator light on the motherboard to flash for just a moment. According to Apple, this indicates that the motherboard is probably good, and that the power supply is bad as it's only providing a momentary voltage spike during the start up faze, before the power drains from the PS. Then it quits. So I thought, is it possible to use the QS power supply, only modifying (rewire) the main 22 pin connector voltages so they match the Imac's pinout? Both connectors are 22 pin and most of the pinout voltages match up the same. There would appear to be only two major connectors that would need to be rewired. So can I use a modified QS power supply to power my Imac?
A couple of extra notes about this Imac:
1) There is no back or stand with this Imac, it just the main guts. So I would need to build a suitable enclosure to maintain proper air flow, and use the QS power supply outside the Imac. That wouldn't appear to be a big problem.
2) My biggest concern is this. The QS power supply uses 28v for the start circuits, versus 24v for the G5 Imac PS. Would this make a significant difference, and if so, why? I'm assuming it will, but it an area I'm unsure of with the Imac. Any thoughts or experiance in this area here would be greatly appreciated.
3) Hey, if worse comes to worse, I can always purchase the extra parts and rebuild the Imac for around $200-$300 US, and it would still be a deal (at least I think so). However, at present this is just a pet project, and if it goes south (doesn't work), it's not like I'm out some major $$$$.
Thanks in advance!

I have no idea whether your ideas would work, but go to xlr8yourmac.com for some ideas. If you decide to purchase parts, try [http://www.synaptech.com/catalog> and also look at [http://www.jimwarholic.com/2008/07/how-to-repair-apple-imac-g5.php] for tips.
Let us know what you end up doing,

I have iPad and I touch can I use the power cord

I have an iPad and an itouch can I use the same power cord

If you only want to use the one charger for both devices (e.g. to take on holiday) then the iPad's charger would be the best one to use as that will charge the iPad quicker, and it's safe to use with iPods and iPhones (http://support.apple.com/kb/HT4327)

Can I use the power charger(85W T Connector) with MBP(17 inch 2010 mid)?

Hi I have a MBP (17 inch 2010 mid). It uses a 85W L Connector. But today, it is not working anymore. And I found a older charger 85W T Connector is work with it. But I want to make sure it will not break my batter when a long time usage. Does anyone know it?
Thanks in advance.
TO APPLE GUYS,
Why the material of your cable has so bad quality? It seem easy to aging. Not only the Power charger, also with your earphone cable and other USB cable.

Thanks. It can work. But the Apple serivce guys told me it make harm my battery. I don't know why. So I want to make sure at here.
I just wish the apple guys could read it in their free time.

Can I use the iPod Nano cable and AC power supply with the iPhone?

Just purchased my iPhone 3G. Phone was in my pocket and the AT&T clerk neglected to put the box with the computer cable in the bag with the other accessories.
Until I can pick it up, can I use my iPod Nano cable? The plug seems the same size but I don't want to break anything.
Also, there was no power supply in the box due to the recall. Can I use the iPod AC power supply I bought for the iPod? It is the white brick about 3" by 3" by 1" with a USB socket in the side.
Thank you for helping me with my start-up glitches.

Ps. When you do get the accessories, look for a green dot (on the side where the prongs of the plug come out). If there, fine; if not, your adapter is subject to the recently announced recall of ultracompact USB adapters.

Can I use the old power supply with the new unit?

I have a second generation Apple TV. When I install the new unit next week can I use the old power supply with the new one and the new power supply with the old one? This would save some messing with cords behind the units.

Hello:
I would definitely not try that..... The power supplies may be compatible - or may not be compatible. I think messing with cables is a small price to pay for not potentially frying a new device.

I had an Intel-iMac fried by lightening. UPS, surge protectors but it happened as I was reaching to unplug. Cold now. Could it just be the power supply? Can I replace that myself?

This is the full question since I couldn't get it all in the box.
I have some complex questions regarding an iMac, a Time-Machine backup, and iTunes on an iPod.
I live about halfway up an extinct volcano about 12 miles north of San Jose Costa Rica. Some months ago, we had a thunderstorm and as I reached to unplug my computers lightening struck about 50 meters from my house. I had an iMac with a 3-Tb external backup drive, a PC laptop and a laser printer on the same power strip. There was a definite surge and the light brighten and then power was lost for a few minutes.
When power was restored, the PC and the laser printer seemed to work fine but the iMac was cold.
First questions: Is is possible that the power supply was fried and not other essential parts? Would it be worthwhile to replace the power supply? Can I, with limited experience and tools do it or need I take it to a technician? My concern is that if the hard-drive is good, there is personal information on it that I don't want to risk.
Next question: Do I need to replace the hard-drive before taking it for service? How hard is that, can I do it? I have seen videos of the drive replacement on-line.
Those are my iMac questions, now the questions about backup restoration.
If there is a saving grace with this it is that the Time-Machine backup seems fine although I have only accessed the data through Finder. I replaced the iMac with a Macbook Air with significantly less mass storage and I can't just move files to the Macbook. My problem is that I have an iTunes library of some 10,000 songs on the backup and until recently on a 160 Gb iPod which was old and it crashed. I have replaced the iPod but have not tried to restore the iTunes library to it because of my confusion about how to do that. Can anyone tell me how I might do that or give me any insight into the process?
Thanks for any help you can give.

Quite possible, but working on iMacs is not easy, & PSU might be prohibitive.
Hopefully the Drive might have info on it, but even pulling that out can be a chore.

I'd get an external drive & restore the whole works to it, then boot from the External drive.

The Power Supply Fan is still working, but does not appear to respond to increased loads, and its speed cannot be increased using SMCFanControl. Any suggestions?

Hi all - My mac pro 1,1 has an enigmatic problem. It's quad-core, 3Ghz, running OS X 10.7.5. The problem began some months back, when running HD video conferences, HD streaming videos and some other graphics-moderate (I won't say intense) uses, such as slide shows in Just Looking. My machine has an ATY, RadeonX1900 card and 2 monitors - both Apple displays, one being 30 inch 2560x1600, the other being 24 inch 1920x1200.
When I start those types of graphics-moderate apps, after about 5 minutes, something would crash (the monitors making a noise as it did) and the displays would both go black. The power did not appear to be fully cut off from the monitors. I think that the underlying applications, however, did not crash. So, I could still hear and speak to people during video conferences, and I could hear the sound tracks of videos.
Attempts to restart the computer and get the monitors back did not immediately work to undo the problem, if done straight away. The only way to correct the problem (so as to have the monitors work) was to wait for a few minutes and then restart.
After a lot of puzzled looking at console logs (and I confess that I am not an expert), I ran into a blank.
But, because of the timing of the crashes (after ~5minutes use) and restarts (after some minutes wait), I reasoned that the problem might be temperature related.
Once on that path of thought, I found this article:
http://worldtv.com/blog/guides_tutorials/fixing_an_overheating_mac_pro_no_expens e_required.php
I installed both Temperature Monitor and SMCFanControl. And I experimented, and got interesting results:
Now to the puzzling bit: SMCFanControl shows that the speed of the Power Supply Fan doesn't vary much, even if I use SMCFanControl to ramp fan speeds right up. All of the other fans react to SMCFanControl, going up to and above 2500rpm when commanded. But the Power Supply Fan does not. Having watched it for a few days now, the Power Supply Fan, according to AFCFanControl, never varies outside of a range from about 600-640 rpm, regardless of what I do with AFCFanControl.
Also (and not surprisingly), whenever the graphics-moderate apps run, when I ramp all the fan speeds up using SMCFanControl, Temperature Monitor shows that the all of the temperatures within the machine plummet, except in the power supply locations. Power Supply Location 2 is the worst affected. Because the Power Supply Fan does not react as the other fans do, the "crashes" still occur.
I could post some screen shots of the read outs of SMCFanControl and Temperature Monitor, although I think I have covered the key points in this post.
It seems that the Power Supply Fan is still working, but does not respond to increased loads.
Instinctively, I'm worried that if that's right, it might be a hard problem to fix. Any suggestions? Help! I would really appreciate them!
Cheers

Thanks for your response Grant. I had already read about, and I think excluded, dust in graphics card/fan/assembly as a cause. The entire inside of the computer, including the graphics card/fan/assembly, is as clean as a whistle. It looks clean. I've cleaned the dust out every now and then (including a few days ago). Also, my undersanding (derived from the article, linked in my first post) is that I might expect to see high temperatures in the Northbridge and memory module B if the graphics card was overheating. According to Temperature Monitor, however, locations do not increase in temperature when I run the relevant apps. Finally, the graphics card/assembly does not feel too hot to touch.
It is strange that SMCFanControl lists the Power Supply Fan as being software controllable, if that fan is not. Still, your comments are consistent with my observations, as the fan simply does not respond to software control.
There are two upsides: First, I've something of a work-around. I've worked out what temperature must be achieved in Power Supply Location 2 for a crash to occur, and I can watch that location in Temperature Monitor, terminating the process before that treshold is reached. Of course, that's not ideal. Second, ramping all the other fans up does significantly delay the onset of the problem, and makes recovery time much quicker.
Is there any donwside to peridically ramping up the other fans when running the relevant apps? Given that it causes all of the other locations to cool significantly, could this lessesn the life expecancy of the mahcine? (I don't want to run the fans up all the time - that's like sitting next to a jet ready for take off!)
Also, a correction to my first post: Yesterday, with all the other fans running on full and running an HD streaming video, the Power Supply Fan did, eventually, slowly, come up to ~740rpm, which is much higher than the ~640rpm maximum I had previously seen, and this may have aided delaying the onset of the problem.
I'm not sure where this leaves me? The problem might now be able managed. Well, sort-of. But it's not eliminated.

Can I keep plugging in my iphone to the power supply despite fully charged to reduce the battery cycle?

Since an iphone battery lasts for 300-500 cycles before losing its juice, can I just continuously connect my iphone to the power supply to avoid using the battery, like how I use my macbook.

Yes, you can but best read this

Since the iOS7.0.2 update to my iPhone 4S, I can no longer choose use of my Bluetooth device if using the power cord to listen to MUSIC or answer my phone (choice of powercord as 'dock,' speaker, & phone only). Was this former-feature now an oversight?? I'd really appreciate having my Bluetooth once again listed as a choice of audio option. Especially considering the battery life is not what it was prior to this update, and requires recharging often.

Sorry to tell you but unless you have a Retail Apple Store close by, they are the only ones I have found with all the adapters and accessories. I bought an extra lightning to usb adapter the other day to use in my truck. Good luck....
