Quicksilver dual 1GHz 2002 powers off for no reason.
My Quicksilver dual 1GHz 2002 powers off for no reason. Could it be because of overheating? I can run it for an hour or 2 and then it simply powers off as if the electricity went off. No warning, no process. I can wait 30 min and power it up for maybe 10 min and the same thing. Does anyone know what may be causing this? There are some logic bd problems too. It will not shut down. I must hold the power button down until it goes off, and to start it up, I must unplug it f power then replug it into the wall to start it up. Yes it is time for a new one, but this one would be nice as a 2nd Mac.
Hello! Look in apps>utilities>console and see if it's throwing a crash log that might narrow down the problem. It could be a weak power supply that's failing when it gets warmed up or a fan that has quit. Tom

I'm listenting to my ipod nano and it shuts off automatically for no reason. I hit the play button and it starts again but shuts off 30 seconds later.
Anyone have this problem? Any thoughts on how to fix?Push the headphones ALL the way in. The plastic on the headset jack must be flush with the Nano body.

G4 Quicksilver Dual 1gig 2002 Not Booting Up
Hello
I have a Powermac G4 Quicksilver Dual 1ghz with 1.5 mb RAM running OSX 10.4.6. Problems started when a friend pulled the power cord out from the mains and realising it, immediately plugged it back to the mains whils computer was in sleep mode.
Now the Mac begins to start up, the cog spins for a short while then just freezes. I tried resetting PMU after removing the battery and leaving for 1 day, still no joy. However this Mac will boot up okay if I hold SHIFT key down.
Also it will boot up okay if the main door is fully open or almost shut with about 1cm remaining open. I have done the following:
1. Removed all the RAM memory except 1 original stick of 512mb.
2. Exchanged memory.
3. Re installed OSX software etc.
4. Ran TechTool Pro v4.1.1 diagnostics
5. Ran Disk Utility, repaired permissions etc.
6. Checked all power cables if they fit okay.
7. Checked Graphics card connections.
8. Checked IDE cable connections.
9. Rest PMU again.
10. Checked for any loose screw or cables internally.
11. Tried different power leads from mains.
12. Scratched my head.
I have been told there may be some sort of possible grounding issue with the metal of the door touching metal of the chasis/ casing, anyone able to shed light on this will be greatly appreciated. I posted this question onto someone elses thread not being aware, sorry I am new to this discussion.

Imacon Flextight 848 scanneThanks Rodney, Gary and everyone else who pointed me to investigate possible solutions to my Mac G4 Quicksilver/Dual 1gig which refused to boot up when the door was closed but booted okay when the side door was open.
Well I checked the microswitch on the top rear of the side door and cleaned contacts with Caig Deoxit with cotton buds etc, unplugged all connections and replugged them etc but still no joy.
Finally I found and used an Apple Hardware Test disk, opened the side door and booted up from it then closed the side door and started the tests (normally the Mac used to freeze when I closed the door but not this time). Well the test revealed the Airport Card to be faulty so I removed it and all appears to be okay so far.
I cannot understand why the Airport Card works okay and the Mac booted up okay from both hard drives with the side door open, this remains a mystery to me and I hope to discovere the answer one day. This is such a good forum and I appreciate everyone's input. I will try to get a more upto date Apple Hardware Test disk as mine is 1.2.1 a bit old now.
Best regards to all.

IMac 27'' keeps powering down for no reason
After about 2 hrs of editing sometimes my iMac 27'' keeps powering down for no reason and then rebooting.
If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time after you had the problem. Select the messages logged before the boot, while the system was unresponsive or was failing to shut down. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). Please include the BOOT_TIME message at the end of the log extract.
If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful. -
I had trouble upgrading my iPad2 toiOS 5.1.I have had it for about 1 year. I had never upgraded it. I tried a few times but I kept getting a message that I would loose everything on my iPad if I did. I bit the bullet andfigured that I would restore it from the back up on my laptop. Some of the backup files were corrupted. I was unable to retore my exchange email or my notes from the noted app.
Today, my iPad shut off for no reason and I couldn't get it to turn on again, even though the battery was 70% charged. I had to press the on button and home button to get it to come back on.I'm not sure what problem you are experiancing but it would be well worth contacting apple.
If you have had it for less than one year it should be covered under warrenty
All The best

my iPhone 4 has switched off for no reason, and now I am unable to switch this on again???if anybody could help about a reboot tip , he's welcome, many thanks...
1. On your iPhone 4 press and hold both the button and the Home button for about ten seconds. After ten seconds you should see the Apple logo showing up.
2. Now try to run you phone again and see if it works.
If a hard reset the still can't get the device back to a working order.
1. Plug in the device to the cumputer and start iTunes.
2. Press and hold the Sleep/Wake + Home for 10 seconds.
3. Once you see the Apple Logo appears, release the power and continue to hold down the home button for about 5-10 seconds. Look iniTunes and see if your device have shows up.
4. iTunes will notify you that you are now in Recovery mode. Click on OK to continue with the restore process.
5. Next press and hold on the SHIFT button and click on the Restore button. Select the latest IPSW file and the prompt appears.
6. iTunes should now attempt to get your device back to the manufacturer setting.
7. iTunes will later give you an opportunity to restore you content from the PC. Every time when you do a sync, iTunes makes a backup so you can choose the latest backup from the sync. -

We were on our computer and it just shut off for no reason. any suggestions?
We were on our computer and it just shut off for no reason. any suggestions?
You haven't provided any valuable data, it could have been a power problem where the computer is plugged in. Personally I use a UPS (Uninterruptible Power Supply) when I plug in my computer for just that reason.
BTW when posting please complete your profile so we know what kind of iMac you have and the version of OS X. Also what were you doing when the computer shut down. -
Powering down for no reason, HELP
My I-Mac G5 powers down for no reason. I will be sitting there staring at it and it will just shut down. Any ideas?
Hello JSug,
You have verified that the Energy Saver setting (System Preferances -> Energy Saver) are not responsable for this? Default settings are to put the computer to sleep after 15 minutes of no input to either mouse or keyboard.
If you have done that I would would try resetting the SMU (Resetting the SMU) -

My ipod turns off for no reason and the battery is fully charged
I've had my ipod for a week and have had nothing but problems with it! It turns off for no reason while listening to music and the battery is fully charged. It even does it in the car while connected to the fm transmitter/charger. Please help! Also I bought a movie from itunes and I can hear the movie playing but I can't see it play. Thanks for your help!
I've had my ipod Photo for almost a year and just had the same thing happen for the first time - it just stopped, fully charged, while playing. And, it froze up in the sleep mode. I followed the instructions to reset it ( toggling the Hold Switch on and off) but nothing happened on the first 3 tries. I let it sit for about 15 minutes while searching in the Help & Apple Discussions forum and, just now tried toggling the Hold Switch again and noticed before doing so, that it had shut off. I toggled the Hold Switch to the locked position (Hold) then to the unlocked position and it came back on!
I'm sorry I can't tell you why it happens. If anyone knows, I'd like to know, too. -

Phone turns off for no reason! Help!
Hi
I've got a Nokia 6300 phone. For some reason, all of a sudden, its been turning its self off for no reason. When i switch my phone on, it starts up like normal, but then a letter 'G' in a box appears in the top left hand corner of the screen, along with a yellow envelope which rotates and turns into a paperclip. Then the screen turns white and the phone turns itself off. This seems to happen everytime i turn my phone on now, i have restored the factory setting, but this has not solved the problem. Can anybody help??? cheers.Thanks to everyone who has had input into this problem for me. I now have my phone working again. What did I do...?
1st I got two of my smarter younger brothers to help and they proceeded to try a variety of things including:-
a) swapping batteries from their phone with mine, which didn't work
b)swapping SIM cards with mine, which also didn't work but did allow us to have a longer play around with my phone as it didn't turn off when a different SIM was in the phone
What worked? We decided to "Restore factory settings" on my phone. My phone doesn't remove Contacts, Calendar entries and one other personal item which I can't recall when you use this function but we still saved my contacts to one of my brothers SIMs and also moved a number of photos, recordings, and video over to my memory card.
Once this was done I put my SIM back in then restored the factory settings. There was just enough time to get to this function, just note that if you do this function you may need to have your "Security Code" handy.
I don't think that there is any conspiracy with the phone companies (I'm with Virgin Mobile), but what I think happened was that my Brother in Law sent me a Xmas message that had some inbuilt functionality (packet data??) that my phone needed to download to view it. I think this was the cause because when my brother's SIM was in my phone I received a msg on my phone that read "Unable to receive msg from..." and I select "OK" which I think rejected it.
Hope this help someone out in the future? Hope that I haven't been to vague. Let me know if you would like any more info.
Cheers, and I hope all get their phones working again. -
My 8820 turns off for no reason. The only way I can get it to turn back on is by taking the battery out. Has anyone else encountered this problem? What did you do?
I think a wipe with JL-cmder with a reloading the OS fresh would be in order...
