PPC G5 dual 2.0 Ghz go sleep and video goes off. funs run fast

Hi,
I have a PPC G5 2.0 dual model June 2004 (8 giga RAM)
My problem is as follows:
- I boot machine, I hear the "bong" sound and after few seconds (after gray screen with logo inside) funs begin to run fast and it goes in a kind of "sleeping mode".
- Power led is on and blink slowly
- if I type a key on keyboard or press power switch, machine goes on and video return. The boot seems to continue in background
- after few seconds machine goes in sleep again
- check if was dust on funs or liquid on the basement of MAC
I tried to:
- change battery inside
- reset RAM
- reset SMU
- remove RAM from slot in the right way (strange thing happened about it...when only 4 slots remain with Ram bank machine doesn't boot and power led blink fast 2 times)
- remove video card (Nvidia)
- disconnect both internal HDs leaving connected just one for time
- reinstall from DVD Osx on the other one HD. Install was successfull and during all the installation period, sleep happened 2 times
Thank you everyone

I would remove the network card. May not be related, but it eliminates it. Is the firmware for this component up to date? That is the main concern, if it has sat there dormant, while you have kept the OS up to date, but I doubt you have updated the firmware for the card to match the OS Updates.
Replace the battery with a new one, for a few £ it's a cheap elimination, if it hasn't been replaced in the life of the computer it's a realistic suspect.
I would reset the PMU again after removing the network card and replacing battery.
If it still doesn't start, try a simple trick, get a hair dryer, warm the logic board in the region of the memory controller, above and to the right of the lower RAM bank, quickly replace the cover, and try to start the computer. If that works it may indicate bad joints in the chip mount to logic board. This can be a problem area on the G5 PM.
If you do get the computer going, install 'Temperature Monitor' and keep an eye on the Memory Control chip temperatures. Avoid activity which cause it to fluctuate a lot. I found active banner adverts on some websites caused it. I believe rapidly fluctuating temperatures over time cause stress fractures in the connections to the logic board, or elsewhere.

My iPhone 4S on iOS7 is stuck on Apple Logo, and it goes off, then back to Apple Logo again for hours. Pressing home button together with sleep button does not help. Plugging the phone to Mac and restart does not help either. What do I do?

Have not backed up for months, so prefer not to lose the data.
Thank you for your help in advance.

Restore iPhone with iTunes on computer. Open iTunes on computer. Connect iPhone to computer with USB cable. Hold both Home and Power buttons until iTunes recognizes iPhone in Recovery Mode, usually about 20 seconds time of holding both buttons. Click the Update or Restore button that iTunes offers.

MDD Dual 1,25 Ghz random shutdown and false time/date

Hey,
A friend of mine has a dual 1,25 Ghz MDD and he really likes it, but for about a month now the mac behaves very strange. The Mac shuts down itself (not the standard shutdown processes, just shuts down) and sometimes there are is a wrong date/time displayed !
I think that might be the batterie, do you agree ? Or can this also be a Board or power supply failure ?

I think it prudent to find out a little more about what your friend calls a"freeze," and to post the version of the Mac OS he's running.
Some freezes are just that--nothing works and you get no notifications of a problem. The other kind is accompanied by a new screen in multiple languages saying you need to restart the computer, or you simply see a lot of code-looking text across the scene. The later is a kernel panic and can be due to either hardware or software. If it's a kernel panic, this article may prove helpful:
http://thexlab.com/faqs/kernelpanics.html
If he's getting real kernel panics, search (command-f) for the word panic and, if the search returns a file called panic.log, double-click it and see if any clues are present.
Your friend should also determine how much free space the boot volume has. Single-click on the boot volume (always the uppermost drive icon shown) and do "Get Info..." from the Finder's "file" menu or simply press command-i. The resulting window will show capacity, amount used and amount free. You want at least 20 percent of the volume to be free space so that the OSX virtual memory process has someplace to write files.

Put if i shut off the magic mouse and put the computer to sleep and turn my mouse back on and wake the computer up the wi-fi connects, this is a bit strange. This there anyone out there with same problem? is this a Mavericks thing that is not working with the apple magic mouse?
Interested in hearing from you.
Thanks

... does my iMac model... support Hibernatemode 3 alias "Safe Sleep" to protect my Mac against damages due to power outage?
You can set hibernate mode to 3, but it seems to me its only benefit could be if power were to be lost after the iMac was already sleeping. Sleepimage is written to disk prior to system sleep. If your iMac lost power while it was "awake" you would certainly lose any unsaved work no matter what hibernate mode you choose.
The problem is that an iMac without power no longer sleeps, it's dead. Upon restoring power you need to cold boot, and I seriously doubt sleepimage can be forced to load in that event. Sleepimage is loaded upon wake from "safe sleep", not from boot as far as I know.
It is simple enough for you to try, so go ahead and see if it does what you want. Other than creating a 16 GB sleepimage file it did not appear to do anything beneficial on the iMac I am using though (a later model).
The file location is /private/var/vm/sleepimage
Configure hibernatemode, verify the file is created, do some work on your Mac, don't save it to disk (and don't use Pages or similar app that saves work on its own), let it sleep, then pull the plug. I think you will see what I mean.

After recent update to airport on iMac, the wifi connection is lost when it goes to sleep and requires turning off wifi and turning it on to reestablish contact.

After recent update to OS on iMac, communication to airport is lost when computer goes to sleep. To reestablish connection, I need to turn wifi off then on.

same problem here.
i have a time capsule.
symptoms:
excessively searching for network
but more often than not, it cant find the correct netowrk that is correctly stored in keychain
if i try network assistant opened through safari not finding its page, then it can find the right network after i enter in the password again. it connects. but only for a few seconds then it loses the connection again.
the only fool proof workaround for me is:
1/ shut down time capsule. restart time capsule.
2/ restart mac with airport turned off.
3/ after restart manually select the network from the wireless icon in the menu bar
airport utility is a complete waste of time
old airport utility is still better.

IPod Touch goes to sleep and shut's off at random

Hey,
When I use the sleep/wake button the iPod responds normally by either going to sleep or awaking from it. But then when I use my iPod (Music, safari, apps) it goes back to sleep again even if I didn't touch the sleep button.
And sometimes about a minute after I used the button it asks me to turn off the iPod.
It doesn't allways hang, but it occures mostly all the time.
And sometimes it also turns to sleep mode when I press with my finger on the top of the screen (not the touchscreen but above it).
I think the sleep button hangs but I can still use it to set the iPod into sleep mode and to shut it down.
Does anyone know how I can solve this??

The same thing is happening to me. And well, my Touch is brand new! Maybe about 4 hours after using it (sleeping it and such) I left it to do some stuff only to return and found my Touch to be frozen on a White Screen.
I restarted it and it was fine. Then at night I updated it to the 2.02 software. I would leave it for about 10 minutes and it would either A) had shut down and need to be turned on again or B) freeze on the apple start up logo or a wonky looking logo for 10 seconds and then start.
This is extremely frustrating as it's completely brand new... like 12 hours new and I've restored and cleared the iPod like 4 times already trying to make it go away. But it hasn't at all both pre or post upgrading the software.

PPC G4 Tower dual 1.25 GHz: Where to find the 9.22 OS install disks

There are some old discussions of this, but by starting a new thread perhaps a solution will be obtained. I acquired two PPC G4 dual 1.25 GHz towers. They do not NOT have FW800. They have only FW400, thus OS 9.22 should install and work. Do not want 9.22 working under OS X. Just need pure 9.22.
Been working for about a month to apply 9.22 to these machines. I've obtained 9.22 install disks from eight sources, such as FTP, Internet purchase, web download links, friends, local stores, etc. Only two of the disks are acknowledged as bootable, and they do boot the machine to completion. But upon starting the installation, proclaim that the install disk cannot be used with the machine. What's the secret to installation ?
Does one install the OS 9.22 software on another G4, such as a DP or SP 800 mHz and transfer the drive to the 1.25DPs ?
Thank you.

Several of those which had and could dual boot OS X and OS 9.2, required OS X to be installed and present, first and before OS 9 could be used as a secondary boot system. The firmware versions played a large role in this and likely there also were in-chip changes beyond firmware flashing on their logicboards.
I spent some time several years ago trying to discover the problem someone out-of-country had in attempting to restore funcational OS 9.2 booting to a DP PowerMac of this vintage, and the answer came back to the actual need to have OS X (in system software package, part of the computer's included kit) installed first. And if the correct drivers were not loaded at the time, the later OS 9 system in the software kit, would not work. And the OS 9.2 could not be installed by itself.
And the detailed facts of the matter were a hard-sell to those persons afar who did not choose to believe them. Finally they posted their question in these Discussions when their computers were fairly new. And I replied to the same questions in the forum. There was controversy even then as not all believed the facts.
All that, yet you could put an OS 9.2.2 into one of these fringe machines if you did not use their install method. Even a 'classic 9' from an iBook G4 (mid-2005) 12" 1.33GHz software packet can be used to boot up an original OS9-only boot computer of an older vintage. The software would have to be extracted in OS X with a utility such as Pacifist, and the files modified very little, put on a USB drive, and dragged in. However some of the correct files for certain graphic cards or other items would be lacking unless you happened to have one of the last retail OS 9.2.2 full install discs that were not limited to specific versions of hardware. And even just these discs won't work on the PowerMac that requires OS X installed first, because OS X controls the installation. If you get past the need for the 'installer' then the actual system will work; or after the OSX prepared the original setup, it could be removed.
To think I had one & gave it away with a vintage powermac
and extras, to someone who had no clue why it was there.
Good luck & happy computing!

G5 Dual 1.8 GHz fans gradually go to full speed and stay there

My G5 Dual 1.8 GHz boots normally and quietly, with no freezes or panics. However, within a minute or so, I hear the fans begin to gradually gain speed. This continues for a couple of minutes until the fans reach maximum speed, making my room sound like a wind tunnel. This occurs with no programs running, just sitting idle at the Finder desktop.
I've checked the CPU & system temperatures using the shareware utility "Temperature Monitor 2.5" and everything is running cool, barely above room ambient, so there is no thermal reason for the fans to "take-off" like this as the heat pipes are doing their jobs to cool the CPUs.
There is no restriction on air flow around the case, and the acrylic side panel is installed. Interestingly, removing the side panel seems to have no effect on fan speed, whether installed or not ... maybe it's just the liquid cooled G5s, but isn't removing the side panel suppose to force the fans to full speed?
I was wondering if this out of control fan speed is a known issue that can be resolved with either a firmware update or software patch? Does this indicate the need for a thermal recalibration?

I've since answered my own question on this ... The reseller had installed OSX 10.3.2 as the boot OS. The (Late 2004) DP 1.8 GHz G5 requires 10.3.5 minimum, and with that update, the problem went away. The G5 now runs quietly.
This was far simpler than I had expected. Thanks.

Dual 2.5 GHz G5 keeps freezing right after startup

I'm having a huge problem with my G5. Last night I put it to sleep and accidentally turned off a peripheral right after which immediately woke the computer from sleep. I waited a minute then put it back to sleep. When I woke the computer this morning it was behaving strangely with certain applications not opening so I opted to restart the computer. This was two hours ago. At first the computer wouldn't even boot up. I was getting a steady gray with the apple logo, then a steady blue screen. I zapped the PRAM and also reset the SMU. Right now it will boot up but immediately freezes within two minutes of loading the desktop.
I'm kind of freaking out because I'm working on some very important projects. I'm really not good with troubleshooting beyond what I already did. Any fast help would be greatly appreciated!
Thanks.

Well, you can bet that shif doesn't trigger the bleep-filter.

Effect Screensaver, Sleep and Display off have on Encoding processes?

I'm trying to understand the effect screensaver, sleep and turning display off have on applications such as burning a dvd, ripping a home dvd, encoding processes, etc.
I'm assuming sleep will abort those sorts of processes?
What about screensaver and display options?
Sometimes I have to run certain encoding or converting processes for a while and I'd rather conserve energy, instead of turning the settings to Never for all.

jeffmdaemon wrote:
Correct, it seems like ANY attempt to turn the display off is putting the tablet into its low powered conncted standby mode. What is it you are doing that is effected by this?
I havn't tried this, but using the enable hibernation method , that is going to network adapter properties and turning OFF the "wake on" in the advanced tab which seems to disable the connected standby, the tablet may resume working like a regular laptop complete with seperate sleep and screen off modes.
Just keep in mind this disables connected standby for good, you will need to hybernate or shut down to turn the tablet off.

Scripting sleep and wake-up

Until Parallels gets rid of the requirement to make the MacPro sleep and be re-awakened before running Parallels to its fullest extent, has anyone put together a script that would cause the machine to automatically sleep for 10 seconds or so and then wake back up whenever the machine is started. CAN a script wake up a sleeping machine?
MacBook Pro 2.0 MacPro 2.66 Mac OS X (10.4.8)

Yes, A reminder would be simple, but I already get that when I attempt to open Parallels without first putting the machine for sleep for a while.
Thus the initial question...
Can a script wake a sleeping machine, and if so, does anyone have one that could run automatically to put the machine to sleep for about 10 seconds, then wake it back up?

Your problem has been reported many times, but causes are as varied as individuals.
Can we assume that a hard shutdown allows a normal restart?
Can I assume that you have used Disk Utility from your OS X install disc to repair the hard drive directory? The freezes and hard shutdowns require that the drive be repaired (not permissions) or soon the machine won't boot at all.
If the root issue is software related, in Console (the application) under Logs, there should be loggings around the time of sleep and logs that tell you what process went wild and froze the machine.
Network activity is also a common casue.
Other info:
http://support.apple.com/kb/ht1776
If hardware related, such as an external drive, other USB device (Wacom tablet) or USB PCI card, ejecting, disconnecting, removing, or in the case of the Wacom, updating drivers, are all potential remedies.

Random shutdown problem on G5 dual 2.3 GHz w/OS 10.4.7

Hello,
I’m using a dual 2.3 GHz G5, and it’s been working flawlessly since I bought it about a year ago. Until yesterday, I was running OS 10.4.5. Yesterday I upgraded to 10.4.7, and as soon as I booted up after the install, I started having a maddening problem with my computer randomly shutting down. (Not sleeping, but a complete power down.)
At first, the shutdown would happen immediately after powering up; my computer wouldn’t even make it to the blue progress bar. I zapped the PRAM and tried something I found online about unplugging the computer for 15 seconds, then plugging it back in. It now boots up, and I can log in, but the computer still shuts down randomly.
There seems to be no pattern to the shutdowns. I tried taxing the processor by opening and resampling huge Photoshop files while lots of other apps were open, and things were fine. Then it would conk out while I was composing an email.
I’ve heard of this random shutdown problem affecting Macbooks, but I have yet to find anything about G5 towers and OS 10.4.7. Does anyone have any info/advice?
Many thanks.

G5 dual 2.3 GHz Mac OS X (10.4.7) 2.5 GB RAM, 250 GB HD

Thanks for the advice. I did check the system.log in Console and found the following altert:
PMU FORCED SHUTDOWN, CAUSE = -122
Now, since my computer is just over a year old, and since this problem happened immediately after applying the 10.4.7 OS update, I found it hard to believe that my hardware could be responsible. After 2 days of troubleshooting, I was stumped; after a 2-hour service call, so was Apple tech support. I ended up doing an archive and install back down to 10.4.5, and all is well.
I tested this issue on other machines running 10.4.7 and had no problems. It seems that the following specific combination of elements triggered the problem:
• PowerMac G5 dual 2.3 GHz (dual 1.8 machines did not exhibit the same problem)
• OS 10.4.7
• Logging in with Open Directory/Active Directory mobile profiles
• iTunes 7
Bottom line: if you’re using a dual 2.3 GHz PowerMac with mobile OD/AD profiles, do not update to 10.4.7, and steer clear of iTunes 7, at least until there is a patch update available.
(And Apple wants to be taken seriously in the enterprise market?)

PowerMac G5 Dual 2.0 GHz Bootup issues

So, although I have much knowledge about Windows and a decent amount of knowledge about Linux Operating Systems, I know little to nothing about Mac OS X. My knowledge of iOS 8.1.2 is very good, but switching to Apple as my main provider of computer and phone systems and parts has been frustrating. I have 3 PowerMac G5's, each the dual 2.0 GHz models that I recieved as a housewarming gift to the Apple community. However, when I start up the computer, I get a flashing symbol with the "Finder" application logo, then a square with a "?" In it, then back and forth with a second between each flash. I've tried holding the option key with and turning it on (with no CD, with a copy of OSX mountain lion on a disc in the drive, and with a copy of Ubuntu 14.04.1 LTS burned to a disc in the drive). I have tried installing the Mac OSX Mountain Lion to the hard drive on a separate computer, then booting it using the PowerMac, but to no avail. Can anyone help me with this issue? I've fallen for Apple and won't revert back to windows, but don't want to buy a whole new Apple computer.
