I would venture to say that your 3pin female adapter should be plugged into a 3pin male adapter on your motherboard. This allows your system to control fan speed on the power supply. I hope this helps you.

Should I check the memory cards themselves? Reseat them?
Yes.
Memtest X or Rember to test the RAM.
Reseat is also good.
The iPhone 4 doesn't like USB 1.1 much.
after the update the computer was working well, except for this freeze when ever I connect iPhone.
I'd try USB 2.0 PCI. That's how I connect my iPhone 4s, and have connected all iPhones and iPods, to my G4.
Never an issue.
Can't say the same for USB 1.1.......
The above (previous post) linked PCI card is cheap enough.
Want cheaper, try this:

The NEC chipset is the desired chipset, regardless of what OS the maker says is compatible.
OS X has native NEC chipset USB support.

Replacement power supply for Airport N base station?

I'm in need of a replacement power supply for an Airport Extreme N base station.
Is this something I can pick up at a friendly neighborhood Radio Shack, or do I need to order the OEM part from Apple?
I don't need the automatic international voltage switching, just something that can power this puppy with US AC. Thanks.

Tom welcome to the discussions.
I would probably call the Apple number.
1-800-MY APPLE
I am sure that they can point you in the right direction.
I am a little shocked that one of the Apple Retail stores can't offer you a Power Supply.
If all else fails, it sounds like you have tried an alternitve, if it works use it, until you can get a replacment.

Replaced power supply same problem

took my imac g5 to apple store where genius told me it needed a new power supply because machine would not turn on and when it did just to gray apple screen Even though the serial number was in the range for extended repair program, i was told mine was to old and did not fall under any repair program. I replaced power supply same issue of gray/white apple screen and fan kicks on loud. reset pram, reset smu, checked diagnostic led lights 1,2,3 all light as they should. Cannot start up with discs either. Anyone with any ideas it would be much appreciated.

What a bummer! If you can get hold of the reseller, go after him for legal discs, if you can't get him, call Apple at 800-767-2775 and they will send you an appropriate set for a nominal fee.

Where can I buy a replacement power supply?

Where can I buy a replacement power supply for my time capsule?

Apple do not sell parts for the TC..
And do not allow their OEM to sell parts.
So you need to bypass Apple and create your own.
Or fix the existing one.

Need step by step directions to install a replacement Power Supply for a HP Color LaserJet 1215

I have a HP Color LaserJet 1215 printer that is only a couple of years old. Had a power problem at home that burnt out the power supplies of two HP Towers, a DSL Modem, and (I think) the power supply of my printer. I have located a replacement power supply but would sure appreciate any one that would know how to replace. I need a step by step guide aas to how to perform such a task.
It would also help to have a diagram of the printer showing precisely how to get to the power supply.
Thanks in advance for any and all help. I have spent days looking for this information and can't seem to find any.

How do I start using the reciept scanner

Mac G5 dual won't start, even after replacing power supply

I was having an issue with the mac starting, getting the bong and then it would run for a while and then shut down. I tried resetting pram and then replaced the power supply. It still does the same thing. Help.

OK, good news/bad news...
We found the problem, but Disk Utility & fsck cannot repair it, it's either erase everything on the drive, or try DiskWarrior...
Your best bet is DiskWarrior, you need the CD/DVD though.

Does Creative sell replacement power supply / ac adaptors for out of warrenty produc

The part I need is the external power supply / ac adaptor. It's rated 3.5 V at 5Am
ps.
I checked every other possibility in the setup of my system and came to the conclusion that the power supply has died. I confirmed this by using a OHM-Meter which showed no power flowing through the device.
The device has a model number on it
Model: UA-450
If anyone knows if/where I can get a replacement part.
I emailed Customer service but have yet to receive any reply.
Thanks in advance,
Steve

Thanks for your note.. I am still not getting any display or Target firewire startup after
several days of off and on attempts to try every variation of reset, pram/nvram reset et.al because i hoped to have one shot at re-booting it to avoid sending it out for repair with data on the hard drive.
I've tried with and w/o battery in... (fully charged). I'm able to get through the PMU using shift-fn-ctrl-power keyboard combo but on subsequent attempts to restart,
power button with T or even power button alone, there is no power-on at all but a few times I've been able to get the PMU reset and before I go to manually restart it, it restarts (chime) itself, however the only thing indicating it is on is that the caps lock key lights and i can hear (listening with my ear to the thing that it's "on..." yet the drive never gets spinning - If there's any other idea to trick this thing into a Target FW startup or other means of accessing the HD to remove certain data i'm still hoping to get this one fixed (esp. if it is only the cost of a Logic Board replacement.
What is really curious is that a few times it has gone to a PMU reset (with the single beep) even when i have just tried to startup with the power-button alone....and then, as i say, restarted (well, powered on..but nothing else...no display, no drive recognition presumably...)

Replacing Power Supply for 20" iMac w/o the Ambient Light

I am pretty sure my power supply is dead for the second time. I've taken the back off and done the power button/reset smu test to see if led #2 momentarily blinks, etc. Taking it to the genius bar is a while to see what they say, even though out of warranty.
Anyway, depending on what Apple says at the store about the cost to replace, I may do it myself. It looks like I need part #661-3350 but I am not sure whether it is considered non-PCF or PFC. Does it matter which one I replace it with?
Thanks.

Hello Twingirlz,
I just removed my power supply and received good guidance from JimWarholic.com. who referred me to this Apple article on PSU replacement:
http://manuals.info.apple.com/en/imacg517inch_PowerSupply.pdf
Here is a suggested source for the 661-3350 power supply:
http://www.dvwarehouse.com/index.php?mainpage=advanced_search_result&search_indescription=1&keyword=661-3350
My G5 1.8 iMac (1st gen)lost it's first power supply at fourteen months. The replacement burnt out recently due to (at least) swollen (defective) capacitors.
So it's somewhat uncertain if your replacement unit will again give up the ghost prematurely. The power supplies I've researched only have a three month guarantee. You can change the PSU without any trouble. But while you have the back cover off, look carefully at the Logic board to check for abnormalities (as in swollen or leaking capacitors (of which there are 25 in plain sight):

How to replace Power Supply in Pavilion 6535

Hi,
I have an HP Pavilion 6535. I want to replace the power supply. I'm able to disconnect cables from the HDD, floppy and CDROM, but I don't know how to reach the cable connections to the motherboard and the fan cable. They seem to be tucked behind the CDROM and inaccessible.
I think I can see the very top of the motherboard connector, but it seems like I'd need to go in blind and follow the wires with my fingers to be able to get to the connectors and disconnect them. This method doesn't seem like a good approach, so I haven't tried it yet.
It makes me think I'm missing something and that there must be another opening that makes the motherboard more easily accessed.
I don't have any experience fixing PCs, but the basic instructions for replacing a power supply seem so simple that I thought I could do it (see http://h10025.www1.hp.com/ewfrf/wc/document?docname=bph05729&cc=us&lc=en&dlc=en&product=59370).
Am I mistaken and should go to a repair shop or are there instructions somewhere that make it clear how to reach the 6535's motherboard/fan connectors? (I've searched the web unsuccessfully for such instructions.)
Thanks for any help.

If there is something in the way remove the screws that hold the item that is in the way, write down how you do it or take photos, then reverse the procedure when you put it back together.
The CD ROM will probably have a couple of screws in the sides, remove them and it will slide out of the way, trained monkeys can build these, so work backwards.

How to Replace Power Supply

I'm stuck with what I thought was going to be an easy job - compared to a G5 tower or an iMac.
I need to replace the power supply in my Mac Pro (2008) but I'm stuck at getting the small cover off. I've removed the metal plate that was under the optical drives (POV when looking through the side). But it seems there's a small cover for the power supply that's similar to the big processor cover for the liquid cooled G5 towers. I can't figure out how to remove that.
Does anyone have a link to a manual or take-apart guide for the Mac Pro?
Thanks!

Before you begin, open the computer, lay it on its side with the access side facing up, and remove
the following:
• Hard drives and hard drive carriers in drive bays 3 and 4
• Optical drive carrier and optical drives
• Any PCI Express cards that block access to the power supply mounting screws
1. Using a short-handled, magnetized 2.5 mm hex screwdriver, remove the four power supply
mounting screws from the bottom of the media shelf.
2. Depress the upper right corner of the power supply and slide the power supply toward the
front of the computer.
3. Lift the power supply a short distance and rest it on the edge of the enclosure.
4. Starting with the top connector and working down, disconnect the four connectors on the
power supply cable from the four connectors on the power harness cable. Note: You must release the locking latch on each power supply cable connector before detaching the connector.
5. Remove the power supply from the enclosure.
Replacing the Power Supply:
1. Rest the power supply on the edge of the enclosure so that its cable can reach the media
shelf divider. Note: The following four steps explain how to reconnect the power supply cable connectors with the power harness connectors. When the power harness connectors are in their original position in the media shelf divider, it is not possible to see where they mate with the power
supply cable connectors. Therefore, the next step shows how to temporarily remove the power harness connectors from the divider for a better line of sight.
2. Starting with the top connector and working down, release the four power harness cable
connectors from their openings in the media shelf divider. Note: Each connector has two locking latches that hold it to the divider. To release the connector, depress the bottom latch first and then the top latch. You may find a flat-blade screwdriver useful in depressing the latches.
3. Placing a hand on either side of the media shelf divider, thread the J1 connector on the power supply cable through the top connector opening in the media shelf divider and connect it to the PS1 connector on the power harness. Repeat for the other three power supply cable connectors.
4. Important: The first three connectors on the power supply cable are marked J1, J2, and J3; the fourth connector is not marked. The four connectors on the power harness cable are marked PS1, PS2, PS3, and PS4. You must connect J1 to PS1, J2 to PS2, etc.
5. Starting at the bottom connector and working up, depress the locking latches on each power harness connector and reinsert it into its opening in the media shelf divider. Important: Test that all power supply cable connectors and power harness connectors are fully seated by tugging on the cables on both sides of each of the four paired connectors.
6. Fold the power supply cable on the bottom of the power supply bay.
7.Lift the power supply and holding the power supply at an angle, llower it into the enclosure until its
upper right corner slides under the corner lip of the enclosure.
8. Slide the power supply toward the back of the computer as far as possible.
9. Make sure the power receptacle aligns with the opening in the enclosure’s back panel and
the four screw holes in the power supply align with the screw holes in the media shelf.
10. Replace the four power supply mounting screws.

Cost to replace power supply

Does anyone have a ballpark figure on how much it would cost to have the power supply replaced in an iMac (early 2006, 20")?
I called my local Apple Store and they won't give me a price over the phone. I have to bring it to the store so they can look at it. I understand why they prefer to do it this way. I really do. However, I work 6 days a week and I don't want to spend a good chunk of my day off driving to and hanging around the Apple store (I have to wait even when I have an appointment) to get an estimate when I may or may not get it repaired (depending on cost). I'm just hoping to save myself a trip and time [possibly] wasted.
I'm positive it's the power supply. My father-in-law started the computer up the other day, heard a "pop" and the screen went blank. Now the computer won't even power up. I looked it up online and I would prefer not to do it myself as it appears to be quite involved.
Any help would be appreciated.
Thanks
Jon

Thanks. I forgot I had one nearer to me than an Apple Store. However, I checked with them and they are wanting to charge me $60 just to look at it to see what is wrong. No thanks. I'm all for supporting local businesses first, but I think I will take it to the Apple Store and let them check it out without the diagnostic charge.
