Power mac G5 unexpectedly goes in sleep mode or shut down.

Power mac G5 unexpectedly goes in sleep mode or shut down.

I have a very strange problem.

I was using my 2 year old G5 without any problem untill some weeks ago. Randomly it would go into sleep mode without any mesage, you could start it again by pressing any key. It would start working for a little while(minutes), but then it would freeze and either go in sleep mode again or eventually it would shut down (without any mesage). However the little light above the power button would stay on. If you don't touch the keyboard or computer it will try to start again by itself.
If in sleep mode it will just come back with the screens I was in or it will boot and try to go to login. I say try because sometime it will shutdown again before that.

It is not predictable when it will happen. Sometimes it doesn't happen for days and then suddenly two days in a row.

I thought it could have something to do with the power supply so I bought a ups power system, didn't help.

Who can help me with this?

I am having a similar problem with one of our G5s at work.

It is a final Cut Pro HD edit suite with a Kona card in it. Sometimes it will just shut down in the middle of work, no errors no nothing.

It does not happen during any specific task, or process. Sometimes starts itself up again, sometimes not.

Is there something specific I can look for in the Log files with Console, I am particularly interested to see if there is a temperature log (I dunno, something tells my brain that heat may be involved, I could be WAY off, but want to check anwyay).

Thanks

Two days ago my three year old Power Mac G5 (at work) shut down four times on it's own. Two of the times I wasn't even using it. Below is part of the Console log from the first shut down:

Feb 6 10:53:40 Brenda-Fraziers-Computer kernel[0]: USBF: 152. 68 AppleUSBEHCI[0x1702800]::Found a transaction past the completion deadline on bus 75, timing out!

This was repeated several times before it shut down. Help! I need to have an idea as to what could cause this because I can't afford to lose any of my work files.

Leo Derks-

Greetings and welcome to the Apple boards.

Have you tried a PMU or SMU reset on your Mac yet?

Which one you perform depends on the exact model of your G5.

Luck-

If DaddyPayCheck's tip doesn't do it try the following;

ENERGY SAVER
If you have issues with a Mac or display that goes to sleep at inappropriate times, you may have a problem with Energy Saver. Delete the following .plist files and restart:

-/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist

-/Users/username/Library/Preferences/com.apple.systemuiserver.plist--
(username is your name or System Administrators name)

-/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist
A restart is very important after deleting these plists. After a reboot your Mac will then generate new ones.

Some, in these forums, have had luck fixing sleep issues downloading the Combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try.
Yours would be the 10.4.8 Combo update. Others reading, download the combo update that applies to you!

Cheers!

A Mac shutting down is a different issue then a Mac sleeping by itself. I would post a new topic on your particular issue so those with that knowledge will see and post to it.

I did the reset of the PMU. I have to see over the next couple of days if the problem returns.

Thanks for the help

Hi Leo

If you find that this hasn't worked for you then I'd suggest looking in your consol.app for some clues.

find this in your utilities folder. When opened click on logs and find system.log in the list. you will need to be logged in under an admin account to view.

Look for the time of the fainting event in the log and see if you have any thing like runaway detected will go to sleep.

In any event just copy and paste the section of the log just beofre and after the event occurs to this forum.

Hopefully someone will know whats going on if it isn't down to the behaviour I've had experience of.

This sounds like a problem that has been floating around on this board before.

Check the system.log in the Console application after this happens. You might see something like this,

Feb 21 21:42:06 TKs-Power-Mac-G5 kernel[0]: PowerMac7,3 Thermal Manager: Thermal Runaway Detected: System Will Sleep
Feb 21 21:42:06 TKs-Power-Mac-G5 kernel[0]: PM73 T_cur=111 >= (T_max:88 + sleepOffset:20)

Just before the sleep command is issued, the console records a huge temp spike on one of the CPU's and puts itself to sleep as a safety precaution.

Feb 21 21:42:06 TKs-Power-Mac-G5 kernel[0]: [3] "CPU A AD7417 AMB" Type:"temperature" Id:10 CUR:31.32768 C
Feb 21 21:42:06 TKs-Power-Mac-G5 kernel[0]: [4] "CPU A AD7417 AD1" Type:"temperature" Id:11 CUR:109.16628 C
Feb 21 21:42:06 TKs-Power-Mac-G5 kernel[0]: [5] "CPU B AD7417 AMB" Type:"temperature" Id:15 CUR:30.32768 C
Feb 21 21:42:06 TKs-Power-Mac-G5 kernel[0]: [6] "CPU B AD7417 AD1" Type:"temperature" Id:16 CUR:67.40827 C

Supposedly this is caused by a miss calibraided temp sensor. Only solution is to have your motherboard replaced. Hope you bought Apple Care, 🙂

Thanks for the input

I did the PMU reset, but it didn't solve the problem. Two days later my computer had a nother episode.
I checked the console.log after that and didn't find any temperature messages.
I did find this:
Feb 18 08:16:28 LeoComputer mDNSResponder: Repeated transitions for interface en1 (10.0.1.2); delaying packets by 5 seconds
Feb 18 08:16:30 LeoComputer kernel[0]: AFPSleepWakeHandler: waking up

Feb 18 08:16:32 LeoComputer kernel[0]: AFP_TCP ASP_TCP SendSleepPkt: sending ext sleep

and later:

Hope this makes any sense to somebody

Hi Leo

You mention checking the console.log file.

what you've pasted looks like system.log material just to be sure Have a look in the system.log file rather than the console.log for the lines at the time of the fainting behaviour.

I'm afraid the material you have pasted is not familiar but I could surmise that a network attached device is trying to re boot your .local server in an attempt to reconnect.

This last is just musing & should be treated as such. Some one here will be able to read the lines you have provided more appropriately.

In the mean time it will do no harm to have another look in the system.log file.

You are right that was from the system.log. I didn't have stored the console log from that time.
This is from the console.log from last feb 28 when it happened again.
