Computer Not Turning On w/ Power Chord

My G4 went to sleep w/o warning (the same issue as this thread post?!?!) and now WILL NOT WAKE UP?! (yes I am aware of this "defect" via other posts).
Any idea why?
Here's what I tried to troubleshoot:
1. A diff power chord
2. Taking battery out and restarting w/ power chord only
3. Taking battery out and replacing, using w/ and w/o power chord
Now I'm pretty sure my battery life was about 40% when it went to sleep - which suggests that maybe my battery is at the end of it's life ... however if that were true, it is NOT turning on with the powerchords (2) that I tried. Help!!!
Let me know ... I have a mac account "holubc" if you want to email me (or cc: me) directly, thanks! --- chris

Chris-Can't be sure it's the same thing with that information. But, to recover from the unwaking sleep mode first unplug from the power chord. Take out your battery. Wait until the pulsing sleep indicator light turns off. Now put your battery back in and plug in your power chord and start up. That should work (if not, you have bigger issues). You'll need to check your log for the overtemp warning to see if you have the narcoleptic Powerbook problem.
To everyone else, here are a couple of points to keep in mind (based on my experience and research).
1. If you see the overtemp message in your log you have this problem. If not, it's another issue.
2. Things that won't solve it: A new battery, a new motherboard, software re-install, OS upgrade (it doesn't matter what OS X version) hard drive wipe.
3. The solution: new trackpad sensor (i.e. new topcase, since they are integrated)
4. Suggestions if you don't have warranty or AppleCare coverage: Keep hounding Apple (they are among the best in service). Provide documentation of your system log error as well as what you have found from these discussions. Be persistant. Insist on talking to someone at the next "tier" of support. Apple may not issue a huge recall or similar that covera all who call with the problem, but with determination you can get them to see it is common issue they need to take care of for free. Insist on it.
4. Suggestions if you have warranty or AppleCare coverage: Get your top case replaced. That's it.

IMac G5 does not turn on after power cord knocked off

I have an iMac G5 that I recently passed on to my daughter. For the past few years it has been working fine except for one occasion that I replaced the power supply. At that time it was still covered by warranty and Apple sent me a replacement unit that I installed myself. Lately, the power cord was knocked off while the computer was on and now it will not turn on completely. It starts for about 15 seconds up to the gray Apple logo then the screen goes blank. I monitored the LEDs and all 3 do turn on then the computer shuts down. At first I thought it's the power supply that was affected with the power cord accident, and bought a replacement unit. I have just installed it but still the same problem exist. I am now asking for help from the expert souls out there to save this computer. Thanks.

No more ideas except to try starting from the install disc and see if that works. Resetting the PRAM might jolt it back to life, it's worth a try, but I am not hopeful.
If you do take it in, please let us know whether it was the logic board...

Computer not turning off

I have a friends old Tiny brand computer with a Micro Star MS-6340 Ver 1.0 mainboard in it
For some reason the computer will not turn off after windows shuts down, also then computer turns on when the mains socket switch is pushed down and not when pressing the on/ off switch on the front of the case.
Thinking it may the wiring on the switch at fault i dissconected the case wires from the on/off switch and the mainboard but the computer still powers up when the main switch is turned on!!
Any help on this problem would be much appreciated. Thanks

This line confused me, which part are you talking about?
In regards to the power up with the switch when the power switch is disconnected from the mainboard are you sure it is disconnected and you didn't disconnect something else?
As for the not shutting down this is probably a windows problem with the APCI. I usually resolve it with a reinstall of windows since it is usually due by the time this happens.

How can I make my computer not turn off (sleep mode, or hybernate)? While plugged into the wall.

I have two dogs, and i am trying to see which one is tearing up my couch while im away by recording via my built in camera and "iMovie". But after a few times trying, I relised that my computer "sleeps" or "hybernates" after only a half an hour. It is plugged in, and i went to System Prefrences > energy saver > then clicked on power adapter and moved both "computer sleep and display sleep" to never. turned off my screen saver. and still having issues with this. Am i missing somthing?
Tony

Thank you Courcoul, i appericate your help. but if you would have read my whole description, you would have noticed i already tried that. "It is plugged in, and i went to System Prefrences > energy saver > then clicked on power adapter and moved both "computer sleep and display sleep" to never." i also did check the schedule times, and it is off, both wake up times, and sleep times.

HT4061 My iPad Mini will not turn on or power up?

The other night when I was updating an app, my iPad Mini screen click and was frozen. I took a trip to the AT&T store yesterday and they tried to recharge, but the screen was frozen. As of today, I can not power up.
Please Help!
Thank you,
Sherry

Is the screen lighting up when your press the home button?. If so a restore would be the next recommended route.
To restore your device fallow the steps below. please note your computer will need internet to do this.
1. Put the device into restore mode. [ Power off Device, Then hold home button with device still powered off. then plug the Data Cable into the device. keep holding the Home button.{ please note the data cable needs to be plugged into the computer for this.} After that you should get a iTunes icon on the screen.]
When that comes on. the computer should respond to it. and iTunes will let you know there is a device detected in a Restore mode.
2. Click on the restore button on the computer. Then iTunes will start to download the new iOS for your iPad. [also note. if the download takes longer than 20 mins. You will probably have to put the device back into restore mode.]
If after this step if your device is not responding then there is a hardware problem. and not a software problem.

Computer not turning on

Hello,
I have a question. I don't know what is wrong with my computer. I was using it, and all of a sudden, all the applications started to crash. I would not let me force quit for a very long time. When it did let me force quit, I managed to turn my computer off. Now, it won't let me bootup. All I have is a grey screen with the apple emblem, and a spinning wheel. I tried to reinstall the software, but it will not let me. I tried running a diagnostic disc, but it wouldn't let me do that neither. I took my computer into the Genius Bar about a month ago, and they said that it was fine. I told them that I thought that the hard drive was going, or the fan/ pram was not working correctly. They said that both were okay. Can someone please help me? Also, I'm a boluda, and put Apple's 24hr. help number for the US on my computer. Can someone please tell me it (it's not sos-apple or my-apple, it's another number) ?
Thanks,
Laureen

Click on the Contact Us link at the bottom of this page on the right. All Apple's contact numbers are listed.
You startup volume is corrupted. I can't tell you if it's the hard drive or not. You will need the OS X Installer Disc for the current version of OS X installed on the computer. Since you have two computers and didn't mention which one has the problem I don't know which OS X discs you need to use. If it's your MacBook then you need the original discs that came with the computer.
You should insert the installer disc into the optical drive and restart the computer. After the chime press and hold down the "C" key until the spinning gear appears below the dark gray Apple logo. After the installer loads select your language and click on the Continue button. Once you get to the screen where you select a destination drive select your hard drive then click on the Options button. Select the Erase and Install option and click on the OK button. Proceed to complete the installation.

IPOD will not turn on, after power ran out and charging for two days.

Slept off while using my IPOD, noticed the next morning that the battery was flat, i charged the IPOD, for one day, try to turn it on nothing happened, charged it for the second day, same thing, it refuses to turn on. Please i will like tips and help on how to go about resolving this problem. Note a friend had same problem and had to charge hers for one days before the IPOD turned on.

If not this:
iOS: Wi-Fi or Bluetooth settings grayed out or dim
One user reported that placing the iPod in the freezer fixed the problem. A trick that works frequently with iPhones:
Settings > AirPlane Mode ON, Do Not Disturb ON
Power down and wait 5-10 minutes
Power up
Settings > AirPlane Mode OFF, Do Not Disturb OFF
If not successful, an appointment at the Genius Bar of an Apple store is usually in order.

Does the iOS device connect to other networks? If yes that tend to indicate a problem with your network.
Does the iOS device see the network?
Any error messages?
Do other devices now connect?
Did the iOS device connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on your router
.- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem and it does not connect to any networks make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

IMac not turning on after power outage

The new iMac arrived and I register at the beginning screen, etc. I'm at the end of the registering when I accidentally pulled the cord out of the iMac. Now when I try to turn it on, nothing happens. At all. I've tried taking out all devices, etc. Nothing will work.

{quote:title=jasperblunk wrote:}I've tried taking out all devices, etc{quote}

is the line cord still in tact?
the power connection, on the back of the iMac, is it loose?
Thanks,

While downloading icloud my ipad locked up at the agree screen any ideas how to unlock .it will not turn off with power button

my ipad is locked up since downloading icloud. icannot turn it off with power button.

That makes sense after re-reading the original question. I thought the OP was setting up for the first time. I must be getting old... I have misinterpreted a few questions over the past few days....Or my brain is on hiatus!

Thinkcentre m93 tiny does not turn on and power indicator led is always red.

Any ideas ? Thanks.

17" Powerbook G4 1.67 GHZ - Will not turn on after power surge !!!

This is showing no signs of life after a power surge. Here is what I have done so far:
AC Adapter - Test OK
DC IN Board - Test OK
PRAM Battery - Test OK
There is power getting to the logic board, but absolutely NO response when you press the power button. I have tried the oh so famous PMU reset and zero response. The AC adapter glows amber, and no chimes or beeps. Has anyone had the same experience or could steer me in the right direction. I am very fearful it is the logic board, any sugestions?

You might want to take it to a repair shop. Something similar happened to me, but the repair shop took care of it in a few days. (The only things I lost were all the apple loops in GarageBand, but that's fixed too.)
