Replacing Power button dual 1G MDD

The front panel power button on my Dual 1Ghz G4 MDD is getting "flaky". I have to push it a bit sideways and to the right for it to work. Any words of wisdom on how to replace the assembly and where to buy it? The local Apple store is only "allowed" to do trades. I bring them the bad assembly and leave it with them, then they will order me a replacement. That could take "a few weeks". When I pointed out the obvious (that I would then have a computer without a power switch) they obviously understood but couldn't do anything about "policy".
Thanks,
Tom

Hi
Instructions for replacing the front panel board can be found here:
http://www.info.apple.com/usen/cip/pdf/g4mdd/g4mdd-fpb.pdf
Unfortunately it's a bit involved as the optical drive carrier and optical drive bezel have to be removed first.
I've never used them before, but the following is one company that seems to have the part for around $50:

I'd double check the problem is with the front panel board and not the button itself in the bezel before you buy anything though. I guess it's possible it's just gunked up and needs a clean.

Replacement Motherboard for Dual 1ghz MDD G4

My original motherboard for my G4 is toast.
What replacement Motherboards are compatible with my dual 1ghz
mdd G4?
The white sticker on board reads: 630T3984/630-4256
Thanks
Eric

Ouch, I was hoping it wouldn't be one of those.
I think it has to be the same. My info comes from an Apple document discussing CPU upgrades.
Wait ... quoted -
Before Replacing the Processor
Important:
Apple has determined a compatibility issue between the processor and certain
fabrication levels of the logic board on some Power Mac Server G4 (Mirrored Drive Doors)
and Power Mac G4 (Mirrored Drive Doors) products. Before ordering a replacement
processor for those models, follow these steps:
1. Open the computer and check the fabrication number that is printed on the logic
board. The fabrication number is easily visible at the edge of the board near PCI card
slot 5.
2. If the logic board fabrication number is 820-1308, 820-1440, or 820-1445, do
not
order the processor module. Instead, you must replace both the logic board and the
processor by ordering the combined module: Module Set, Logic and Processor (Apple
part number 661-3654).
Replacement Warning:
When ordering this combined module set, a returned logic
board must match one of the three fabrication numbers (820-1308, 820-1440, or 820-
1445). If the logic board does not match one of these fabrication numbers, it will be
rejected.
3. If the logic board fabrication number is any other number (
not
820-1308, 820-1440, or
820-1445), order only the multiprocessor module (Apple part number 661-2730).
So make of it what you will. If your email address is in your profile, I'll email the whole document - it's a bible for MDD owners - shows you how to remove and replace everything, with photos. It's only 3.3MB.

How to replace power button

I have a PPC mac mini and a matching La Cie HD which stacks on top. This serves as my home music station. BUT obviously we want all the cables out of sight and this means they all face to the back as does the power buttons for the mac and the HD. And this means I'm the only one in the house who can fiddle blindly round the back of both drives to turn them on. Even I am getting fed up trying to 'feel' for both of them, they are the same 'dimple' style.
What can I do to replace them with more visible and positive switches. I don't much care if they aren't aesthetically pleasing just that they are visible and positive, possibly even mounted on top of the stack with extended wiring if you get my drift.

Why not just sleep the Mac and wake it up with a mouse click or key stroke instead of shutting it down. Not only is it easier on the hardware than numerous cold boots, but you can start working enjoying it in seconds instead of minutes.
FWIW' I sleep my Mac's 24-7 and never fully shut down any of them unless I going to be away for several days.

Out of Warranty Replacement - Power Button Not Working

Well this is fun. A month and a half ago I paid the $229 to have an out-of-warranty replacement iPhone 4 shipped to me. Now, the power button is malfunctioning on it. When I press it, it does nothing, and at random times when I'm not even using the phone it'll prompt me wiht the "slide to power off" screen. Do I have any options to fix this without paying Apple another absorbitent amount of money?
I don't have luck with iPhones, apparently.

Definitely call in to AppleCare (800-APL-CARE) and refer to the repair number if you happen to have it, otherwise simply give them the serial number and explain the situation.
It's very likely they'll want you to restore the phone, so you may consider doing that before calling.
I'd agree that it sounds like it's hardware, however the phone rep will decide how to troubleshoot appropriately.
You should be good though with the 90 day warranty.

Iphone 5 power button not working!! They have replacement program for months but why they dont email you and say it??

I have had iphone 5 and have never been happy and i think apple is not leading the technology and future of market anymore as they are lowering quality of their products(even hardware). I had to change first iphone 5 i had because of wireless issues and then i had battery problem and had to charge 3 times a day and finally after 2 years i bought they decided that its faulty and they decide to change it. Luckily enough i read it on an online tech magazine and after googling i see that they have had replacement for power button as well which i am eligible for as well!! i go to genius bar and they replace battery but they dont replace power button cause they examine it and passes till the audio dock test! It connects to charder dock or cable but it doest to audio test dock and he says one off the pins inside is not right but it charges perfectly with every cable in the store!! And i tell him that they have to change power button not the charging pin cause it doesnt make sense!! Its a faulty product and maybe if they emailed and said it nearly a year ago my pin was right then!! so i think they found a silly reason not to change it and so i am struggling with that phone and brand that i hate(once i used to love)!

Compaq presario sr5404f power button

Does anyone know where I can find a replacement power button for my compaq presario sr5404f case? The original button is broken.

Power buttons rarely fail, but it can be replaced with a momentarily closed push button ( closed only when being pushed ). Other than a physical break, what makes you ask?

Acer Aspire 7750g Power button board compatibility

Hey guys! First post here on the Acer community forum. I have a question regarding my Acer Aspire 7750g. I bought & installed a new motherboard but I've been dealing with a major issue concerning the power button board. It seems to either have stopped working or the ribbon has shorted out, I don't have the means to test which part is defective, but no power is running to the power button board so I can't turn it on. I've been searching all over the place for a replacement power button board to no avail, but came across one for an Acer Aspire 5750. I know that certain components are interchangeable between both laptops but I don't know about this particular piece.
Are there any experts out here that can verify if getting a 5750 power button board would work? Or could this cause some potential problems to the new motherboard? I'm desperate to get this machine back running so that I can work again. Oh, and if anyone knows where I can get a 7750 power button board for a decent price in case the 5750 board doesn't work I would be greatly appreciative.
Thank you

G4 MDD power button going bad?

Hi all -
I'm using a g4 MDD dual 1gig machine. Has been working great for the past few months, till just now. When I power down, the computer won't restart, unless I unplug it. (what?) That's right, the computer works fine, I turn it off and the power button will not turn the computer on unless I physically unplug the machine for a split second. After that it powers right up (at least for now). Prior to unplugging, the power switch does nothing, no lights, no chimes, nothing. It's like there is no power going to the compuer at all.
Does this sound like the power button is going bad or maybe something else? A few months ago I had PRAM/ PMU issues - could they be coming back?
Any advice is much appreciated. Thanks in advance!

I took care of my power-up issue tonight by working on my power supply. Here is the posting I made in another thread:
Here is what I did to troubleshoot my power issue. Your power supply can be serviced and this post offers a couple thoughts and some troubleshooting suggestions. Please read it through to the end. This isn't a cure-all for all G4 Macs, but the steps I followed seem to cover a number of bases and might prove helpful to those who are really frustrated.
I've owned a Mac every year all the way back to 1987 and have never had an issue until now and I am convinced my problem may have been triggered by a power surge or brown-out, which we seem to have experienced a lot of around here lately. This post refers to the Samsung power supply with Apple Part Number 614-0224.
I have a G4 Dual 1.25 MDD I purchased in 2003. I have had a brief issue with powering up my CPU. It wouldn't power up last weekend. I unplugged the power cord, then reconnected it to the machine and it powered up. I reasoned the power cord had become loose, but then last night I couldn't get it to come up at all. Not even a click. No lights.
So I tried all the easiest possible solutions: resetting the PRAM (pulling the battery from the logic board) and resetting the PMU (Power Management Unit). The switch, by the way, is located near where the ATA drives plug in to the logic board. Neither of those two things solved my problem. The CPU would still not power up.
I checked the lithium battery voltage with a voltmeter. It was at 3.6v, so it was still good.
I then decided my issue was probably with the power supply. With the power cord disconnected from the back of the CPU, I pulled the black power connection from the logic board and performed a power supply voltage test following the pin schematic found in this thread:
http://docs.info.apple.com/article.html?artnum=58561
The +5v trickle voltage found at Pin 9 was not present. I had no other voltage readings on any of the other pins. My issue HAD to be with the power supply.
Tonight I removed the power supply by disconnecting all of the optical drives (I have two DVD burners in this unit), all of the hard drives (three) and all of the logic board connections.
I removed all of the screws from the outer casing of the power supply, including the fat screws attaching the two black fans to the unit and the one long screw in the middle and near the edge of where the two fans are. The casing came right off.
There have been a lot of questions as to whether there are fuses in these power supplies. There has to be some protection for them and I have yet to see any power supply that did not have a fuse or resettable circuit breaker. This power supply was no different...it has a 250W, 8A fuse that is easily accessible and is located on the same side as the male power socket, near the edge of the circuit board. It is hiding under a yellow shield and is right next to a plastic connector.
Bingo! My fuse was blown. Many glass fuses will show some sort of blackness and mine did, as well as being able to see the actual glob of metal where the fuse burst.
What caused a fuse to blow will be different for each machine. I believe in my case it suffered from a power surge. There were no visible signs of burns from arcing, popped capacitors, shorts or bad chips. The board was completely clean, which tells me the issue was near the power source. The fuse may also have been on the verge of popping when I unplugged and reconnected the power cord.
Everything's speculation, but replacing the fuse did the trick in my case and I saved myself time and about $150 (on average for a used PS on eBay). I picked up a second fuse to tape to the inside of the CPU, near the power supply, so I will have a backup fuse if I need it in the future. I may also have a drive that is going bad, or I may have too many drives operating off one supply. My Mac's been configured like this for about five years now. I will replace at least two drives with new, larger capacity drives. I keep my video and digital image files on separate drives, but have a third drive I can blow out. That surely will help prolong the life of my power supply.
While I had the computer apart I gave it a good vacuum and a little air can action. Dust can aid overheating and defeat the purpose of good airflow from fans.
Hope this helps.

No Chime, display or illuminated power button QS Dual 1 Ghz

Hi. I have a PM G4 Dual 1 Ghz. It was a great computer until about 2 years ago when it sadly stopped working. I found a broken capacitor on the motherboard (No. 820-1342-B) , so figured it was a bad MB. I replaced the board with a (No. 820-1276-A) board and had no luck. The symptoms-the same as on the new board. I purchased a tested and working board (No. 820-1342-B) and still had no luck. I am beginning to suspect a problem with my processor card or my power supply but I don't want to put any more money into it. I have tried to reset PRAM but the keyboard isn't recieving power. The symptoms: Power light when pressed in, red light on logic board, fans, hd, and optical drive work. No keyboard, display, or chime. Please help- I want to donate this computer and can't bear throwing it away

You never said if you replaced the PRAM battery.
I would check it first. When mine went, I had no response from my Mac at all; just a light on my power button; absolutely no boot at all.
For G4's and earlier models, check out things in Texas Mac Man's Battery, PRAM, PMU tutorial on the subject.
There are other tips in there too.

G4 1.42 dualie still won't start after replacing power supply.

This Machine was turning off randomly for about a week when it just stopped working. The power light would go on when pressed, but nothing happens.
Tried plugging into a wall socket instead of power strip. Nothing. Reset PMU. Nothing. Battery is good.
Read though many reports and determined the culprit was the Power Supply. The power supply was replaced with original Apple part. The problem remains. Press the power button and the light goes on, release it and the light goes off. Nothing spins up, no chimes, nothing.
Now I'm reading it may be the power button - someone solved the problem by attaching an older keyboard with a start button. I don't have one to test.
I don't want to keep shooting in the dark on this one.
Thanks for any help.

Hi wagsfx, and a warm welcome to the forums!
Good research so far!
Now I'm reading it may be the power button - someone solved the problem by attaching an older keyboard with a start button. I don't have one to test.
Too bad you're not closer, I have 5 I don't need, because buying 8 was cheaper than buying on on eBay!
Anyway, my suspicion is that if that KB thing works it is the Power Button assembly, but that other things will start going wrong shortly there after.
It's likely not any consolation, but I think the MDDs are the worst G4 ever turned out, I wish I could have my $20+K back from buying, repairing, & upgrading them, since all 3 are now dead as a doornail.
Hang on though, there's many far greater experts here than I, & I hope they can drop in with some better ideas for you!

Dual G4 won't turn on. Power button just blinks

Hi everyone, first off I'd like to say that I know there are a number of similar posts to this but I read many of them and I think mine is a little different.
Earlier today my Dual 1.42 G4 powermac was on and was in the screen saver. I pressed the sleep button on my Apple 23" display and nothing happened. I waited about ten seconds and, needing to leave, pressed it again and left. Well, I returned now and found the computer was off. I pressed the power button on the display and nothing happened. It just blinked. I then pressed the power button the computer and it did the same, just blinked for a second.
I just followed Texas Mac Man's directions from other post by unplugging the power cable and removing the battery. Waited ten mins and tried power it up and nothing happened. Same issue. There are no start up chimes/beeps and the fans do not spin up.
I also found a link that showed how some powermac's power button go bad and that a usb keyboard with a power button can start it up. My display has a power button and it couldn't turn the computer on so this isn't my issue, right?
Some info about the comp: Dual 1.42, OS 10.5, everything stock except a ram stick I added three years ago. Thanks for your help in advance and can't wait to get this old champ running again.

I debated starting yet another "my G4 won't start" thread since my problem is more similar to Tammy in MO's.
My Dual 1 Ghz G4 (Mirrored Door) won't start up when I press the power button. The power button usually does not light up upon touch. The computer does not shut down on me when I am working on it.
The only way to get it to start up again is to unplug the power cord from the back of the computer for a minute or two (not long at all) and then plug it back in again. If I do this, I can run the computer all day without any problems. Once it goes to sleep or shuts down, then I have to unplug it again and start over.
I have done the following:
Replaced the battery.
Reset the PRAM:
http://support.apple.com/kb/HT1379
Reset the PMU:
http://support.apple.com/kb/HT1939?viewlocale=en_US
as well as done the PSU test:
http://discussions.apple.com/thread.jspa?messageID=9301520&#9301520
This last test yielded no voltage results, best I can tell.
Truth be told, I don't think I did the PSU test properly since the ends of my voltage tester are probably a bit too large to properly test the pins.
http://img244.imageshack.us/img244/4280/fw800pinout.png
I even tried to discharge the power from the logic board:
http://discussions.apple.com/message.jspa?messageID=582223#582223
BTW: The red led on the logic board does come on and stay on when the unit is powered up and running.
I was wondering if this has happened to anyone else, and if anyone knew how to solve the problem.
At this point since this machine is relegated to my wife and kids so for me it's more annoying than anything else. Any other suggestions or advice would be appreciated.
Thanks in advance.

I have an iphone 5 that was originally with verizon but has been unlocked now by them and the phone is still under the apple warranty, if I go to replace for power button malfunctioning, will they give replace it with an unlocked phone as well?

I currently have an iphone 5 that was verizon locked but has been unlocked by them because of my contract, the phone is still under the apple warranty but the power button is not working, if it was the case that apple has to replace it with another phone, will they replace with an unlocked phone now?
thanks

The SIM Lock is stored on the Apple Activation Server - if it has been correctly unlocked by a network then this would have been done on the Activation Server.
When you get your replacement handset through Apple they mirror the activation server details of your existing handset and the current SIM LOCK status is mirror'd onto the new device.
(100% Accurate - done mine 2 weeks before christmas due to original 5 sleep button stopped working)

IPhone 4 Power button no longer works. 2 Months out of warranty, I haven't got $179 to replace it, any ideas? I have attempted self repairs, made the situation worse.
