G5 Dual 2.0 GHz won't turn on. Motherboard part numbers and compatibility.
The power LED will blink three times in succession indicating a memory issue. Have swapped RAM, PRAM reset, PMU so I think my m-board is bad. Would like to purchase a used one. Are original dual G5 2.0 GHz motherboards interchangeable? If so, what are part numbers I should be looking for?

Greetings and welcome to the Apple boards.
This document is to help with troubleshooting a computer that won't turn on.
My guess is that you need to do a PMU reset.

My ipod touch 8gb won't turn on, recognize a charge and when I plug everything in nothing comes p on the computer. I've had it for about 8 months and took really god care of it.
Try:

If not successful, make an appointment at the Genius Bar of an Apple store.

I have an Apple Power Mac G5 Dual 2.3 GHz/6GB RAM/500GB HDD/Superdrive PowerPC Desktop and just bought an Airport Extreme card for it. The card is recognized but will not see the in-house network. This is a pre-intel computer. Do I need an additional antennae? If so, which one because my research is confusing me about what is supposed to work with this computer.
Please check out the following Apple Support article to see if your particular Power Mac model supports an external Wi-Fi antenna.

3G still won't turn off after hitting home and sleep button at same time. Any other ways to try?
3G still won't turn off after hitting home and sleep button at same time. Any other ways to try it?
And when you held them neither the red Off slider nor the Apple logo appeared?
If not then your sleep button is broken, you will need to get it serviced. -
My white 4th generation iPod touchs turn of slide button is stuck on off but my iPod won't turn off for some reason and it only shuts off when the battery dies. It's been stuck like this for some time. Please please please help!!!!
First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
Finally, if the Restore doesn't work, let the battery drain completely. Then recharge for at least an hour and Restore again. -

Follow all the steps in the article below:

If the issue remains it would be best for you to back up your phone then book an appointment at an Apple Retail Store to be evaluated.
Hope this helps -
Macbook freezes and won't turn on after using itunes and going to standby
My macbook pro "locks up" when I am using Itunes and I let my computer go to sleep or to standby mode. It won't turn back on without manually shutting it down and restarting the computer. I have had hardware diagnostics done on it and they all report back fine. If anyone knows how to fix this issue it would be greatly appreciated!!!
The computer may think it is syncing with the iPod while you are attempting to go to sleep, thus is stuck trying to know what to do. Try dismounting the iPod first, and then disconnecting it, and then putting it to sleep.

IPad won't turn on, cvcles update bar and apple logo
Hi guys
My iPad won't turn on after I tried to charge it last night. What happens is I'll try and turn it on and it will go on to the Apple Logo, then the little bar will appear as if it is updating. The bar will get to about 2% of the way across, then the bar will disappear. Sometimes it will get to the lock screen for a brief moment before going straight back to the Apple Logo. This will just repeat persistently. I have tried holding the home button and lock button together, and all this does is get rid of the update bar, but the logo screen cycles. Any ideas on why this is happening and how to fix it?Frozen or unresponsive iPad

IPhone won't turn on after replacing LCD and Screen
My dad replaced the glass digitizer and LCD panel the screen won't turn on. what could go wrong that would cause this?
I plugged in into the wall charger and it made the charging sound but still the screen didn't turn on. The sound works and vibrator also. I held the home and power button and nothing happened. I took a snapshot and I heard the picture sound. I also hooked it up to my computer and iTunes synced it but still the screen did not turn on. What could I do to make my screen show and be able to use my phone again? Please Help!! Thanks in advance !As deggie poined out, it could be any number of things. If your dad can't fix it, you may need to find a competent repair shop or buy a new phone. Apple will not service that one.

Ipod won't turn on unless is reseted. and that takes 10-15 minutes
After a couple of months working properly, the problems started. I turn it off by pressing play/pause until screen goes off. After it's off for less than an hour, it won't turn on by pressing play or any other button. It will only come alive by reseting which takes 10 to 15 minutes before the apple comes out. Yes, I do the select menu thing properly, before I had this problem it took only 10 seconds to reset it when I had to. Any idea? Thanks
If it's taking that long to reset then it doesn't sound well. I'd recommend you check the iPod's hard drive for errors by sticking it in disk mode. Reset using *Menu & Select > 6 secs* then hold *Select & Play* as soon as the Apple logo appears. Once in disk mode connect to your PC, find the drive in Windows Explorer, right-click and open Properties, go to tools and check the drive for errors. Once you've confirmed the drive is OK or fixed any errors a restore in iTunes should correct any problems with the firmware & library on the iPod that may be causing it to behave badly. Don't forget that a reset will wipe out everything on the iPod so check you have your originals before proceeding.

Need Methods for Testing Hardware -- Dual 2.0 GHz Won't Boot
Have a Dual 2.0GHz Power Mac (M9032LL/A) that won't boot.... I'd like to know how hardware is diagnosed on these machines? I hear the Apple Hardware Test CD isn't that accurate and not really any help and there's no LED lights on the logicboard of these models, so, short of swapping stuff out, how do I tell what's bad? I'm assuming either a processor, the logic board, or maybe the video card are bad and would like to verify what may be wrong.
The computer doesn't boot reliably but once it is on, it works great. When the power button is pressed, there's no chime, but it makes the other usual appropriate noises, such as the fans and hard drive briefly kicking up and back down... then no more progress. The mouse never lights up (it's optical and flashes when the computer starts up normally), no video ever shows, and the computer just sounds like it's sitting idle-- the fans are slightly on, but the hard drive makes no noise. After several minutes, the fans begin to go into overdrive (the wind-tunnel sound) and I just have to shut it off with the power button.
This problem has become increasingly more bothersome over time-- it used to happen only occasionally. Now the computer won't start on its own at all. Booting into open firmware has tricked it into booting, but has become less and less reliable (described below).
+For those that may be able to help further than recommending hardware testing methods, here's specifics on my situation:+
Troubleshooting I've done:
- reset the PMU (can't remember if I've reset the PRAM)
- installed a new power supply
- tried a different monitor and power cord
- installed a new battery
- re-seated video card
- removed the two sticks of third party RAM... when I booted after doing this, the boot got further. This time the computer acted like it was on, but with no video... it responded to the keyboard (volume and eject) and appeared to show up on the network. I checked monitor by plugging it into laptop, and the monitor worked fine, so I assumed the computer's not outputting any video. Force-shut-down and rebooted the computer, but it went back to the same boot problem described above (fans went into overdrive).
In the past I have successfully booted it by booting into open firmware, then typed 'mac-boot' and the computer starts up and works completely fine. It's not flakey, doesn't crash, etc. However, it won't reliably boot into open firmware!
I've also successfully booted into single-user mode. Both in this mode and in open firmware, the fans will go into wind-tunnel mode after about the several minutes as it does when booting via power button alone. However, the command line is still responsive, and a boot command stops the wind-tunnel noise as the computer then boots.
I'd really like to rescue this computer, it's such a speedy, reliable machine that's given me years of excellent performance. If it's time to let it go, I'd like to know for sure, so a way to test the hardware, especially the logicboard and processors, would be nice...
Many thanks for any help,
Selena M.To those that offered help, thanks, I appreciate it and ended up finding the problem using the most basic hardware test of all-- remove one of the parts on the suspect list, so long as the computer can run with out it, and see what happens, and that resolved my issue!
To those having the same problem-- I found a fix for my machine and it's working great!!! The primary suspects were: logic board, RAM, CPUS or video card. If it was the logic board or a CPU, I'd just call it a parts machine, so tried removing the other parts to see what happened. Still crashed/didn't boot without the third party RAM, and also no difference without the Apple RAM.... but when I removed the video card and hit the power button-- there was that startup chime I hadn't heard in so long!!!!! The machine booted immediately and responded properly to the keyboard's volume and eject buttons. Since I couldn't attach a monitor, I accessed it over the network and it was working fine. I shut down and booted several more times, and it came on every time. So, if those of you that are having the same problems haven't tried this, see if your computer boots without the video card...
*Best of all*, the new video card was free! Apparently the card in my machine has known issues and they'll replace it for free if you send them your old one AND mention this article: http://docs.info.apple.com/article.html?artnum=32473. Read through it, and if your video card matches that model number they list, call the phone number they provide. Make sure you mention the article number, which is 32473, so they can reference it and so they won't charge you an over the phone tech support fee (because this is for a recall). They'll look the article up, ask you what you did and so on. Tell them you tried everything the article suggested and that your computer behaves as the article describes, and they'll send a new card.
Also, note that I'd seen this article before when trying to solve my booting issue, but my computer didn't behave exactly like they described, so I just kinda blew it off. But later, while skimming various forums for answers, I read a post from someone with similar booting problem to mine and he offered the above tip and article number. It's a good thing too, as it saved me the cost of a video card! Otherwise, I just would have bought a new one.
Anyways, I hope this can help one of you out that are having similar problems... just remove that video card (if you haven't already) and see if your computer works. If so, get a new one for free from Apple and hopefully you'll have your computer back!
Good luck! -
IPad won't turn on without power cable and when it does, it shuts down within a few minutes
This last weekend I went to visit my sister and when I came back, my iPad was turned off. I turned it on again and all seemed fine but then within a few minutes, it went straight back off. It won't start up without the power cable attached, and when it does, it says "No WiFi" in settings, not "Not connected", but it's greyed out and says "No WiFi". I did a restore which went OK, but when I was restoring it shut off too and the restore didn't carry through. I'm really worried! I can't visit an Apple Store for a week, so I just wanted to see if I could get a rough idea of what the problem is now?
Your iPad is in Recovery Mode.

HP 655 won't turn on, power light on and won't turn off.
My HP 655 laptop has apparently gone into sleep mode, permanently. It was up, went into sleep mode and now it will not come back up. I have removed the battery and unplugged the power source for an hour. As soon as I plug in the power or battery, the power button lights up but the laptop will not turn on, no matter how long I hold the power button down. I even plugged in the HDMI cord to make sure that it wasn't the screen, obviously, which it wasn't.
Hello ,
To get your issue more exposure I would suggest posting it in the commercial forums since this is a commercial product. You can do this at Commercial Forums.
Even though this is a Commercial product, try performing a hard reset. Lots of information in this document that could help.When performing a hard reset please note remove any and all USB devices. Disconnect all non-essential devices.
Here is a link to computer won't start for Windows 7. Windows 8 here.
Here is a Youtube video that might help. It shows you how to reseat the HDD, which sometimes helps.
