My iMac wont power on either

I have a G3 iMac 400mhz DV that has run with no problem ever. Had a power outage today and now will not power up at all. No lights no static no anything. Pulled battery, put in new battery. Pushed "cuda" button, still nada. Any ideas where to go from here? Is this common?

Try things in Texas Mac Mans tutorial, including what to try if all else fails at the end.
I'll post it here in case you miss it;
-I found this on a Mac site. Sometimes computers lose their mind. Don't ask me why or how it happens but it does. Sometimes you simply have to totally discharge the computer. One thing I have learned about the Blue and white and the Gray G4 Macs is that sometimes pushing the PMU is not enough. If your machine is dead, then try the following.
* Unplug the unit.
* Remove the battery
* Push the PMU switch (count to 5 slow)
* Push the start button on the front of the Mac (count to 5 slow)
* Let the unit sit for 15-30 minutes
* Replace the battery
* Plug it back in, and push the start button
If it doesn't work I usually repeat the steps above, pull the RAM, and let it sit longer. If it doesn't work after this, it is take it to the shop time.
Cheers!

IMac wont power up now!

Hello,
I just back from the apple store with snow leopard excited to install it on my iMac about 2 hours ago to find my iMac frozen and it wouldnt let me hit the shut down button. So i just hit the power button on the mac and now it wont turn on. I tried to reinstall the OS but when i go to install it, it doesnt even show a hard drive to install it on.
I still have apple care for it, so does anyone have any suggestions? And, if it is a failed HD will the apple care replace that or would i be better off just buying a new iMac? My iMac is almost 2 years old, i bought it refurbished from apple.com
Thanks for any help in advance.

If you have AppleCare, use what you paid extra for...
if it is a failed HD will the apple care replace that or would i be better off just buying a new iMac?
If it's covered, it will not cost you anything to get it repaired. So even if you decide to get a new iMac, you should get this one fixed.
You can try resetting PRAM
http://support.apple.com/kb/HT1379
and if that does not help, resetting SMC
http://support.apple.com/kb/HT1543
which is unplugging the iMac from power and reconnecting it following a precise procedure. When you reconnect it, try connecting it by itself to a wall outlet directly, instead of to a power strip with other devices. Disconnect all of your peripheral devices, except for your standard USB mouse and keyboard.
If that does not get the hard drive to be recognized and working properly, use that AppleCare.

IMac wont Power Up

My iMac has an issue, if all users are logged off after a designated amount of time my iMac powers off but the only way I can restart it is to unplug the power cord from the unit wait a few seconds then reinsert the power cord, only then will it power up.

My imac wont power up

My iMac froze, so i held the power button on the back to restart it, now it wont restart properly. It makes the chime sound and the fans are working, the apple logo appears and also a loading bar on the bottom of the screen, which i am pretty sure it doesn't normally do that. After around 30 seconds it just powers itself off again before the login screen can appear. How can i fix this?

Carefully read and then methodically follow each of the steps in Gray screen appears during startup

New twist:iMac wont power on

Ok, I've read the other posts regarding this but my symptoms seem a bit different. For about two weeks my iMac has been turning itself off after sitting idle for abou 15 minutes (it's normally on 24/7, although I let it sleep alot). As of this evening, i won't turn on. I press the power button and it goes orange for about 5 seconds (which is norma) then, when it flips to green (this is when it powers up the CRT) it dies.
Help! I need my emal and contact lists!

Robby,
By your description of the problem, it sounds like a classic analog board failure. You must have a tray loading imac judging by how the orange power light turns green then the computer turns off. The problem with the computer turning off after 15 minutes was just the beginning of your problem leading to the end result of not being able to turn on the machine.
I hope this helps in fixing your problem and makes your decision easier to purchase a new mac or purchase a replacement part.

2006 imac wont boot ! g5 cord ok to try?

My late 2006 imac wont power up after a power outage. I did have it plugged into a surge protector tho that is over a decade old by now, didnt think of that earlier. I just get a black screen, no change when i press the power button after it being unplugged.
I Wanted to try the hardware test but the cd drive wont pull the cd in like it normally does when i place it in there.
I have tried an smc reset, no change.
I have an old g5 that no longer works. Im thinking of trying to use the power cord from that to see if its the cord that is the problem. would that be ok to try?

You should be fine trying the G5 power cord.

Why is that whenever there's a power outage or whenever I restart my computer sometimes my iMac wont completely load up? It will just show a blank white screen. It will do that for a few days until it decides to fully load up.

First step would be a PRAM reset.

Post back if that does not work.
The next step would be to try "Repair Disk".

I want to upgrade my ( iMAC 800Mhz Power PC G4 & iBOOK 700Mhz PC G3)

Hello!
I want to upgrade if possible over 1GB ? my now slow computer ( iMAC 800Mhz Power PC G4 ) and a ( iBOOK 700Mhz Power PC G3 ) which I don't think I'm confident enough to change the internal memory but the user memory I think I can attempt!
So I'd like to know what type of ram or "model numbers" I should be looking for if I what to upgrade my empty DIMMO /J22 slot to a 1GB ?
Keeping in mind I still have a 256GB factory standard ram in place (256 SDRAM PC133U-333)
i.e. how many pins "184 0r 200" do I need for for my model?
I seen lots off ram types like "Kingston PC2700, 333MHZ DDR 1GB memory "
PC2700 333MHZ is this the model number I should be looking for to upgrade to 1.256?
and for my ( iBOOK 700Mhz Power PC G3 ) is this also able to be upgraded to beyond the the original ibook specs just like it is suggested for the iMAC? which I also have only the original 256 SDRAM and a empty ram slot! again I not sure what model or type of ram I should be looking for here? or what is the max. it can be upgraded to with the new high density ram everyone is talking about!
I know you guy's must seem to answer these by now simple question for you! am sorry I don't have something more challenging for you but I do need your help with this one please!
since you've already done this and seem to know what your doing! I would like to ask for your help or anyone who know the answers to my questions ?
Thank you in advance!
Millenniumbug

Unfortunatley, only imac models above 1ghz can take module of 1GB. your model can accomadate 512mb bringing it up to 768Mb which will make a decent improvement.
go to crucial.com and input your imac model to get the right type for your system. it's also best to buy from mac friendly companies as some cheaper modules wont work
best of luck

1st gen. iMac G5 power supply failure

Hi, all!
My 20" iMac G5 here at work collapsed and died on me about a week ago. The computer just deactivated abruptly; I actually had thought that I had kicked the plug or stepped on the power bar by mistake. I restarted it, and it worked for twenty minutes before dying again. Now it's entirely unresponsive. Having read up on the matter here and in the Mac support pages, I'm quite sure the power supply has failed. I'm in the process of finding out whether the computer is still covered under Apple's Repair Extension Program. (http://www.apple.com/support/imac/repairextensionprogram/ - I know the iMac model is correct, my serial number matches the range, I'm just not sure if the computer is less than three years old.)
Anyway, the important thing for me is the hard drive, not the machine itself. We're entirely Mac-based here at work, so there is no shortage of machines for me to work on (I've already replaced my old machine with a much newer Intel-based iMac), but I would very much like to retrieve my data from my old hard disk. I've downloaded the DIY guide for opening the 20" iMac G5 and removing the hard drive, but I need some advice on the best plan of action. Should I then open another, working G5, remove its hard drive, insert my old hard drive and transfer my files off to my new iMac through our company server? Or is there another way to approach it? Is the hard drive on my 20" first gen G5 compatible with newer mac models, or am I going to run into problems with connectors, physical disk size, etc.? Or, should I just leave well enough alone and leave the entire operation to a Mac Genius?
This will be my first time opening an iMac. I believe that I can open the machines and remove-replace the hard drives without voiding any warranties, correct?
Thanks so much in advance for your help and advice!

I am on the phone right now with a product specialist about my iMac G5 power supply issues. Kind of ***** because he has, in so many words, said that the Genius is the Alpha and Omega and can extend the 3 year coverage. For me that is great except that the Apple store is over an hour away. I don't understand why the dude on the phone can't pull the switch and make it happen as well.
Factor in:
Unplugging iMac G5 and all peripherals
Loading it in the car
Driving an hour
Carrying it into the Mall (apple store)
Waiting for my Genius appointment
More than likely getting it fixed for free (from the sounds of things)
Driving back after it is fixed
Doing everything listed in reverse.
Would it just be easier to pay the $108 for a new power supply, wait a few days, undo some screws, and BAM! it works again?
Update. Off the phone now. The product specialist flexed his muscles, back handed the Genius to gain authority, and basically stated that they WILL DEFINITELY repair either the power supply or the logic board or both if needed. I have already had them replace the logic board once. BUT, I still have to load it up and take it to the Apple Store. Boo.

Iphone 4s wont power on, im just getting a blank screen with battery charging on front screen

iphone 4s wont power on, im just getting a blank screen with battery charging on front screen>>>>becouse it is after damage water

At Apple Store, if you have AppleCare +, replacement iPhone 4S costs $50, if no +, then it will cost $199. Either your battery is faulty, the power management is faulty, or the charging port is faulty, or all three. Start with battery replacement. If still problem, then try charging port with flex cable replacement. If still problem, then it is very complex fix or no fix at all possible.

Imac wont boot, stuck loading, all i see is apple logo and spinning cycle

My 27 inch iMac wont boot, i am runnign snow leopard. I just see the apple sign and the cycle spinning meaning its still loading. I cant use disk utility because leopard install disc wont boot, also i cant run any commands in single user mode, doing /sbin/fsck -fy does nothing, i dont see a # sign or anything, whatever i type it doesnt matter whenever i hit return the cursor just goes to the line below.

Power down (assume you have already tried the SMC reset) and insert the Applications DVD that came with your new iMac. Boot up while holding the "D" key down (may be best with a wired keyboard) to run the Apple Hardware Test according to these instructions:

IMac wont boot up

My IMac wont boot up! I installed the Mac OSX system disk and ran disk utility this is the results:
invalid node structure
The volume Macintosh HD needs to be repaired.
Error: Filesystem verify or repair failed.
What do I do to get this up and running again, I would appreciate any help.
Thanks,

I called applecare and they were able to get my iMac up and running. Apparently there is an issue with updating software. I just had to do an update today and ended up with the same problem. So I re did what the applecare rep told me and I got it going again myself. I am hoping this will not continue. So anyway, I am going to provide the steps on how my I got iMac going.
1. unplug the computer for approx 17 seconds.
2. unplug everything from the computer except the mouse and keyboard.
3. plug in the computer
4. turn on the iMac and hold down the option key at the SAME TIME
5. when the iMac comes on, it will make a loud beep noise, CONTINUE to hold the power and option key until a small the Mac HD icon displays.
5. When the Mac HD icon shows on the screen, release the power button and option key. Then click on the arrow below the Mac HD icon.
5. The iMac will boot and take you to the desktop. Then click applications
6. choose the utility folder
7 then choose disk utility
8 a screen will appear that states first aid. At the bottom, there will be an option to repair disk. Click on that then choose Mac HD.
9 When this is finished, you are good to go. These steps will repair what ever the software updates are doing to the hard drive.
Hope this helps.

Imac wont boot

My late 2008 iMac wont boot. I have tried everything that i understand but cannot accesss harddisk.
I cannot boot fron dvd -cd or usb. I would like to run diskutil from terminal to repair and verify. System hangs/ stops running, when i try command+v ,message that (vmcl: Module initialized.)
Command + s puts me in single user mode and i cannot run diskutil.

Imac 2008 24" 3.06GHZ/2GB/500GB/SD8X/GF8800GS/512.
Downloaded and installed Lion recently, all software is ligitimate.
Running vmware / Vista, occasionally.
Machine just stopped, froze up.

Hei, just to let you know. I gave up and delivered my machine to mac repair. It turned out that a module error was the cause of my problems. They have since replaced the defective part and my machine works like a dream. No reinstalling either, all existing files and software are intact.

My computer wont power up. I have unplugged it for 30 min and replugged but it will still not power up. Can I try something else? cant get an appt until Tuesday.

Until Tuesday, the only thing you might try, if you already have and didn't state that you did, if this is the same outlet that you have used, and suddenly you lost power, try plugging your computer into another outlet and see if that works. If it works, either try another appliance in the outlet you are having trouble with, or check to see if a breaker has tripped.
If that doesn't work, well...you will just have tro wait until Tuesday.
Wish you the best of luck

Nx6325 charging led solid amber with no battery and wont power.which motherbrd component is faulty?

I have 2 nx6325s.one has developed a fault where with the charger plugged in the charging led flashs once green then goes solid amber with or without the battery connected.The laptop wont power on.The charger and battery are both good as tested on the other laptop.I suspect a component in the charging circuit has gone faulty.Would any one know which component I should look at and what to measure.
Thanks

>If I remove the battery the laptop will not power on either and only when using a fully charged battery will the laptop power up. The battery icon shows it to be charging only briefly when I plug in. I've even tried another AC charger even though mine is good (tested) and also tested with another battery to no avail.
Indeed, it sounds like something wrong on the motherboard it could be related to power supply electronic which is placed on the board power problems can be related to faulty RAM modules too so maybe you should check the RAM firstly remove one single module and try to power up the unit using one module in different slots
Otherwise you would need help from a notebook technician... ;(
