Replacing a power supply on a 20" PPC iMac (iSight) - easy?

I'm pretty sure this is the problem - iMac is dead - nothing happening at all, apart from a VERY feint clicking deep inside somewhere, only heard with ear pressed up against the case.
I can see lots of info on how to inside an Intel iMac, but scant detail on opening a PPC G5 iMac. Is this because it's difficult? I see some folk use a bent credit card to release the 'fingers'... looks like fun
Otherwise, as this is my spare machine, it may be time to buy a new machine and recover the files of the old G5

All things are possible; judge for yourself if it's worth the hassle.

My 27" Imac (A1312/EMC2390) keeps shutting down unexpectedly with no warning or "screen of death". I replaced the power supply, reset the SMC, and zapped the PRAM, but the problem continues. Can anyone help me?

My 27" Imac (A1312/EMC2390) keeps shutting down unexpectedly with no warning or "screen of death". So far I reset the SMC, and zapped the PRAM. I even replaced the power supply but the problem continues. My error and system logs seem unhelpful too. Can anyone help me out?

You can get a shutdown like that if the computer gets too hot. Make sure the air intakes on the bottom and the exhaust vent on the top are clean and are not blocked by something in your workspace like papers or the back of the computer being too close to part of the furniture. You need a good six inches (15cm) of clearance between the exhaust slot and other objects or surfaces.
Anti-virus/internet security software, especially the "pay for" kinds, can increase operating temps. So can third-party backup software furnished with many "name-brand" external hard drives.
Fan motors and/or temperature sensors can fail. If you have the original grey disks that shipped with your iMac, find the on that has Apple Hardware Test (AHT) and run it. If you have a failed heat sensor or fan motor, it will detect it with an error code containing "SNS" if it's a bad sensor or "MOT" if its a bad fan motor.

I have a 1st Gen Time Capsule 1tb. It turns on, boots up and turns green for 5-10 mins, but then turns solid orange and then blinks orange. I have removed the hard drive and replaced the power supply . . . still the same problem. Suggestions?

I purchased a used 1st Gen Time Capsule with a 1 tb hard drive.
When I plugged it in and did the initial setup, it worked fine, but gave me a hard drive error. A few minutes later the green light turned solid orange, then blinking orange, then the status light went off. The lights in back stayed on.
I removed the hard drive and rebooted, it turned green for 5-10 minutes then reverted back to a solid orange, blinking orange, then went off.
Next I purchased a remanufactured internal power supply, and installed it (without the hard drive in). It turned green almost immediately. After about 15-20 minutes, I decided to try to install the hard drive again, booted it up, and tried to erase the hard drive with was working properly according to the software. It stopped erasing the disc after about 20 minutes and turned solid orange again, then blinking, then no status light (but back lights were still lit).
I'm a bit flabbergasted at this point, any suggestions on what to do next? I think i've pretty much replaced everything except the logic board, but can't seem to find any information on the symptoms of a logic board malfunction.
Thanks!!!!!!!

A Gen3 is identical board to a Gen4 although they have some differences in firmware and wireless card was updated on every model.. but a Gen3 is substantially faster than Gen1, Gen2 which also have identical boards.
You can with careful shopping get a Gen3 pretty cheap.
Most use a delta power supply which I think is a lot better than the flextronics used in most Gen1/2
You can sell back the parts to ebay.. people still would buy the power supply etc. Even just the case can be useful to a repairer.
But if the board is gone.. it is hard to repair.. not impossible.. but hard.
Gen 3 and Gen 4 are not without faults.
See this page.

I have fixed it a different way.. by using the small converters you can buy in bulk from ebay for $1 each.. KIS3R33 .. they produce 3.3V at 2A peaking at 3A.. amazing.. I keep using them to replace onboard power converters by removing the inductor and simply power directly.. the end result has worked great. You can simply change the resistors around and get any output from 1v to 20v depending on input.
Is it worth doing it .. no of course not.. it will waste many more hours than $50 is worth.. but it is kind of fun that you can actually make things work again.
Here is a pic of the Gen 3 totally powered by me. All onboard power removed.
This was to track down the fault in the Gen3.. but I am kind of pleased that it ended up neat enough and reliable enough to work for more than a year.. the Gen3 still serves as a way to get Netflix via network for a friend running 24/7.
The units supply (from left to right)
1v, 1.1v, 3.3v, 5v, 1.8v
It is feed by 12v supply which is also directly connected to the hard disk.
So it is possible to fix.. !! Only got to be a bit crazy.

I just replaced the power supply in my Intel imac and now the screen is really really dark and I see the missing folder icon, what do I do?

The power supply in my Intel iMac went out (and smelled pretty burned) so I replced it and now when I start it up the display is so dark I can hardly see it and it shows the missing folder icon. Is it the inverter? Or if shine a flashlight on it and re-install the OS will changing the display settings maybe fix it?

Thanks for ur quick reply to my problem. I tried all of that with no results... I did notice tho that the lights next to and above my caps lock key and my num lk key are now flashing. They flash in unison three times then there is a two second pause then they flash three more times and this repeats. They may have been doing this before I tried this solution but I did not take notice until now... I was also wondering how I am supposed to know, after pressing f10 to enter bios, how I can tell if my new drive is being detected when my monitor will not function? Was pressing f10 supposed to possibly make the monitor turn on? In a last ditch effort to try and further identify the problem, I re installed my old drive. Before replacing it my computer would begin to boot then display a hard error that would not allow me to continue booting and run Windows. My display would still work but I could not run Windows. After re installing the drive the monitor will not turn on. I'm beginning to think that I have a bad monitor. Is there a way of testing this with out buying one? Where does the monitor connect to the mother board? I wonder if maybe its been jarred loose, although I highly doubt it, it may still be worth looking at. Thanks again for your advice.

To replace a power supply

Hello All.
Hard drives and Ram upgrades/replacements are pretty easy to come by but i wanted to ask if anyone can advise me on where to get a replacement power supply from (if i have no applecare) please. I wanted to see the costs involved. Im guessing that its not that hard a job swapping over the power supplies on i macs?
Thanks for your time
W

The costs of getting any one of the items you describe would far exceed the cost of purchasing AppleCare. IMHO it is wise to get it because with just one problem it would pay for itself not to mention the piece of mind you have for 3 years.
It can be purchased for less than Apple Charges (at least here in US) so that would extend the savings even further.

Replacement upgrade power supply hp e9140f

I have a HP e9140f that has a Bestec ATX0300D5WC power supply that needs replaced. I would like to upgrade to a higher watt power supply. What would be a compatible replacement?

I prefer the Rosewill 630W, but I would never disregard the CorsairCX 600W. Both are exact fit.

Trouble replacing the power supply for a 20" imac g5

I have purchased a new power supply and going through the replacement instructions but I cannot get the cable to disconnect. In the instructions it says
4. Disconnect the power supply cable by pressing the connector release tab and using a
wide, flat blade screwdriver to pry apart the connector.
5. With your fingers, pry the cable off the connector.
But the parts simply will not come apart and the plastic is just getting all mangled and making it more difficult. Is there some sort of trick to this?

Don't keep forcing anything or you'll end up having to replace those cables/connectors.
This is what I might try, however, I have to say I have never had to do this and maybe someone who has will have a better idea: You might try dribbling an extremely tiny amount of silicone spray downwards into the connector. Don't allow it to get on the outside of the connector where you need to grip it. And don't spray the silicone directly; first accumulate a little in a small container (one of those small cough syrup measuring cups would do), then try to get some on something that will hold only one or two drops and feed it in from there. I don't think it will reduce the conductivity of the contacts, but try to keep it only on the plastic, if possible. Shake the can of silicone spray well before using.
You might also try using a small piece of a non-slide rubber mesh pad, the kind used under rugs, to help grip the connector better. And jiggle it a little from side to side while pulling it out.

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.

I need help to replace my power supply for the hp pavilion elite m9510f

This computer has given me many problems since I bought it in '09. From graphic card fan issues, a hard drive crash, and now the power supply has failed.
I did the blow dryer trick but it still ends up breaking a week later. I want to know what new power supply should I buy. One that will be able to fit in the hp pavilion elite m9510f and is an upgrade to the 350w that it has. Maybe somthing under 60-70 dollars if possible. Thanks for any help.

It appears to be a normal case and motherboard. A normal ATX supply should work: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=50001333&IsNodeId=1&Description=Computer...
Just an example of what is availble, but most any should work as long the physical dimensions match the one installed now.

Replacing the power supply

Hi,
My old PowerMac G4 (Gbit Ethernet) does not power up anymore. When I press the power button nothing happens at all. I suspect a recent power outage might be to blame - when the power returned the power supply to my router was dead and two fuses popped in the fusebox during the following weeks.
Luckily I bought a new Mac Mini 6 months ago and most of the data has already been copied to the new harddrive.
If it's possible I'd like to try and repair the G4 myself. I was hoping I could use a power supply I had salvaged from an old PC. The dimensions are the same but it seems some of the connectors are a bit different. For example the power connector to the motherboard has 2x11 pins instead of 2x10 and the one for the fan looks different too.
I've tested the voltage of the lithium battery and it's still working. Same goes for the PC power supply. The G4 is supposed to get 28 V of 'trickle' power through the two extra pins; here however I get nothing.
Is it possible to buy/get hold of a new power supply that suits the G4 or is this another one of Apple's crafty non-standard solutions?
So, what are your thoughts?

Hi-
You have a few options-
1- A used PSU
2- Using a wall wart to provide the 28v trickle, along with an ATX(PC) PSU, or,
3- An aftermarket PSU already to go in, from Nextro.
For modifying, and using an ATX PSU, check Out of Spec and Xlr8yourMac.

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.
If you don't know the model, find the Serial# & use it on one of these sites, but don't post the Serial# here...
