Power Mac G5 won't go to sleep

I know this question has been around but not sure what the definitive answer really is. I cannot get my G5 to sleep (recently upgraded to 10.5.8). If you manually tell it to sleep in the apple menu, it crashes/freezes. I tried putting a blank DVD in the tray (something I saw in another post) no help. As a sidebar, when I try to put the Hardware tool in from the original disc, it says it's not compatible with my Mac-even though it is the original disc. What can I do to get it to sleep or diagnose a potential hardware problem???

Ok, working on the 2.3 DC right now. This machine has trouble going to sleep but remains asleep once it's there.
I shut it down, reset the SMU and also unplugged the outlet for about five minutes, then reboot. I changed the sleep timer for 3 minutes for testing and it went right to sleep on the first try.
Then I went and connected the mac mini and now it won't go to sleep. I then disabled wake for admin access on the 2.3 DC. Still it won't sleep. Every three minutes I can hear the HDD click or spin down but it still doesn't sleep.
Guess I'm just wondering if it's connected to another machine if it prevents it from sleeping, which could be the case on both machines.

Power mac G5 won't wake after sleeping

manual sleep start - OK for less than 5 minutes but not more than 5 min. Possibly Logitech 3-button laser mouse? I've read that it's usually a USB issue. nothing else is connected at this time and the power saver system prefs including drives are all set to never. Thanks in advance.

Printers have been known to cause some sleep problems.
Disconnecting the printer will tell you right away....
The mouse shouldn't be a problem.
Try starting in Safe Mode and see if the machine sleeps in safe Mode.
If it does, and after a restart to normal, does the problem still occur?
If so, try a new user account.
Does the problem continue?

Power Mac G5 won't boot with Lion?

After installing Lion, my early Intel 2010 Power Mac G5 won't boot. There were no problems for the first 2 days. The third day my G5 wouldn't boot at all. Not using Lion's recovery function, many attempts to boot from a previous system disk, and firewire target mode. The keyboard seems to be dead after attempting to boot except for the DVD eject key. All I get is a grey screen with an icon of a folder with a question mark within the folder. This icon blinks on and off continuously. Since the keyboard isn't working, I can't reset the PRAM, start in safe mode, or any other keyboard commands. The failed boot doesn't even get far enough for the Apple window to open. I replaced the hard drive and accomplished nothing except for spending even more money and time.
This is VERY frustrating! Has anyone else had a similar problem with booting after Lion't installation??
Thanks.

1) you have a Mac pro Early 2009, remember this. It avoids confusion here in forum
2) you're HDD's OS cannot be found by the firmware of the Mac hence it results to a question mark
perform the following(recommended to use a USB keyboard)
a) startup manager
press and hold option on startup. Do u see your HDD?
b) if you have a back up of your data then you can boot to the install disk and perform an erase and install
repairing the permission will not work since the disc's OS is different from the HDD's OS.

Power mac g5--won't boot, and I can't sleep

Hi all,
I'm hoping someone is awake and can help. My power mac g5, circa 2005, has always come with some problems, specifically, kernal panics. It's not bad RAM, but I have never tested the video card. Oddly enough, it seems to go down most often in the most in simple internet applications.
Today, it froze in Firefox and I cannot get it to reboot. It stalls/freezes in the gray apple screen. Called my IT friend, and he said to zap the PRAM. That brought it back up for a second, and then it froze again. I replaced the battery, no results.
I can't get it to boot in safe mode or even single-user- it freezes up as well. I certainly can't get it up long enough to load the boot disk.
It may be garbage...I can accept that...but it is holding hours of work. Will I be able to retrieve this??

Hi, I'm having same problem. G5 1.8 dual processor purchased March '05, won't boot. Not from cd either.
Took it to the apple geniuses and first was told it might be a bad board or processor and that I might as well just buy a new system. Well, I can't, because I still need to run some classic applications for business reasons, and because of that I'm stuck at Mac OS X 10.3.9. Anyway... I left my system with the apple geniuses and got a call 3 days later saying it was fixed @ no charge and that the 3rd party USB card was bad. They pulled it and said all was well.Great!, saving me $800 charge for a new board and over $430 for a new processor. So on the way home I buy a new USB hub get home start up and nothing! No change. Back to the Apple Store and after some testing this time I'm told it's definitely a bad hard drive. So, on the way home I buy a new hard drive. Get back, install the new HD and, you guessed it, can't format the disk, system won't boot from CD. BACK TO THE APPLE GENIUSES AGAIN! Now they tell me it's definitely the logic board. After 5 days I'm back where I started... except I have an old USB card that is most likely fine and new USB hub and a new HD I purchased because the Apple Geniuses told me they were bad! I asked them if they would apply a credit of some sort for the unnecessary purchases and my time (The closest Apple Store is 30 miles away), They politely said we appologize for the inconvenience, but no, we can't do that. I've been using Macs of all kinds since the early 1980's. And have never had one fail! Since I started looking into G5 problems, I've found many others with this startup issue. I feel there is a known issue with this series that apple is intentionally sweeping under the rug instead of issuing a recall or credit.

My Power Mac G5 won't sleep anymore

Hi there,
I have a dual-2.5Ghz G5 with 3GB RAM and a 30 inch monitor. Recently, like in the last couple of weeks, my mac won't go to sleep for good... I hit sleep, and then it takes like 30 seconds, powers down then immediately powers back up again. I'm confused by some of these other posts as to what to do... can anyone help? I have a really amazing brand new machine and this is really annoying.
I have the bluetooth turned off, and the energy saver set not to wake up for anything.

Try trashing these 2 .plist preferences and reboot. Reset your Energy Saver preferences.
HD > Library > Preferences > SystemConfiguration > com.apple.AutoWake.plist & com.apple.PowerManagement.plist
Also, try closing your mail app before sleeping.

Power Mac G5 won't start up after a security update, please help!!!

Hi all,
My Power Mac G5 version 10.4.11 keeps showing a black video, no beep, no start up chim, this occured after updating a security patch 2008-7 from Apple website, asked to reboot then I encountered this mess.
The powerlight is turn on with solid white color. My display also has its powerlight turn on with solid white. But not nothing happens, except the fan noise becomes gradually louder and louder. I wait for hours ... but ...
My system just won't start up. Although I tried to reset the SMU, reseated RAM...
I tried also to re-install the OS by CD but it's impossible to insert it to the DVD tray.
Any help is greatly appreciated, thank you for your time.
Sgmed.

Hi BDAqua,
After weeks of strugle I can use my MAC as normal, but everytime I shut it down, she cannot wake-up, I had to refer to your hints in order to start it up again. So right now I can use my MAC every day with "SLEEP" mode.
She just cannot RE-START or wake up after a SHUTDOWN.
Any suggestion is greatly appreciated, here under I pasted the log file retrieved from Disk Utilities.
(I tried also to reset PMU, SMU and PRAM but nothing helped. Perhaps she is in need of a brand new PRAM battery???

Power Mac G4 won't boot in OS X

I have a number of G4's which have been upgraded to Tiger. I am on the last machine running 9.2.2 and it refuses to boot in 10.4. I have tried the Tiger installation CDs, from a firewire drive with a good copy of Tiger on and from a new internal disk with a clean copy of tiger on (Installed via another Mac). All I get is the G4 sitting there with a blank screen with the fan running - no start up question marks or anything.
Does anyone have any idea why this mac won't recognize OS X at all?
TIA
PS Firmware update claims that it is not needed.

First let me ask you this, when you install for the first did your machine boot from the 10.4 or not.
And if you did, sounds like everything is ok if you have what you said you have
G4 350mhz, 512mb RAM, 40 gb drive with OS 9 ,80 gb drive with 10.4
(1) Have you check the Battery Type 3.6V Lithium maybe is out.
(2) did you removed the processor if is 350mhz or did you remove the video card.
Here's a link that might help you out that's if you haven't done it already.

Power Mac G5 won't start up and is beeping

Dear friends,
This morning, my Power Mac G5 started to beep. When I try to restart it, it beeps some more and also makes a clicking sound like a metronome.
The computer won't start up anymore. At startup, it displays a grey screen with a little folder in the center that flashes a question mark and a finder icon.
What is wrong with my excellent computer, and how do I fix it?
Marnie

Marnie Glickman-
Could be a variety of things, but most likely your hard drive is not happy. The flashing question mark means that the system is trying to find a working disk with a valid system on it. Should be the hard drive. Isn't.
Launch from the install DVD of the latest OSX system you have. Under the Apple Menu should be the Disk Utility. Launch it and try repairing your hard drive and see if that does the trick.
If not we dig deeper into this excellent problem.
Luck-

My Power Mac G4 shut down instead of sleeping

Is there anyone out there having this problem..?
When I put my PM to sleep it shut down instead. If I try to restart it right away it starts booting but fails after a couple of seconds and shut down again. If I wait for a longer while it starts like it should!?
I have tried to replace the backup battery with no luck.
Power Mac G4 "Quicksilver" Mac OS X (10.4.8)

Hi! - I had a similar problem with my G4 which I bought second hand. It would sleep and then when I tried to awaken it - it would then shut down. Long story short - it had a third party Airport card which I removed as I did not need it - problem solved! Seemingly third party bits and pieces can sometimes cause this problem.
Hope this helps.
G4 Power Mac Mac OS X (10.3.9)

Help!! My Power Mac G5 won't start up!!

I was working on my computer when all of a sudden everything froze. I tried all the key commands and no response. So, I held the start button until it shut down. Then when I tried to start it back up again after a few minutes, by pushing the start button, only the fan starts. No start up chime. Nothing on my screen. Then the fan starts getting louder and louder like it going to explode! I quickly held the start button again until it shut down. I read through the manual and tried everything it said and still the same thing. I read through alot of the questions and answers on this forum...found alot of similar questions, but no answers that I can use. I tried replacing the surge protector, but still nothing. My business & life is on this computer and stupid me, I didn't back up much! Help!!

If your computer won't display video but you can hear a startup chime, fans, drive noise, or you see the power light turn on, the first question is whether you have an external display attached (such as a Power Mac G4, Power Mac G5, Mac Pro or Mac mini) or if the display is built-in (such as an iMac, eMac, MacBook, MacBook Pro, iBook or PowerBook).
For external displays
Try these steps to resolve the issue:
Make sure that the monitor is turned on and has power. Make sure that the display's power cord is plugged into a working wall outlet, and that it's properly connected to the power adapter. (To check if the wall socket is working, plug in a lamp or other electrical device.)
Check that all video cable connections to the computer video port and to the monitor are properly connected.
Examine the pins on the video cable connector to make sure they are not bent or damaged in any way.
Connect a known working display (if you have an extra one available). If you see video after doing so, replace your old display.
Reset the computer's parameter RAM. (Click the link for instructions.)
On a Mac mini, reset the computer's PMU. (Click the link for instructions.) For Power Macintosh G3, Power Mac G4, or Power Mac G5 computers, check your user guide for the location of the PMU reset button on the logic board.
Next we're going to check to see if the computer has video when started up from a disc:
Find the Install or Restore disc that came with the computer. Insert the Software Install and Restore disc into your CD/DVD drive. The disc may look something like the picture below.
Shut down your computer.
Once it's off, hold down the C key on the keyboard and start up your computer. This will start up the computer from the Software Install and Restore disc instead of your hard drive.
If you see video when started up from disc, you may have corrupted software. You can use the Archive and Install feature of the Mac OS X installer to reinstall. This kind of installation gives you a fresh version of Mac OS X, but you don't lose any data from the computer as your old information is all archived.
If you tried all of the steps above and the computer still won't display video, contact Apple technical support (1-800-APL-CARE in the U.S.) or take your computer to your local Apple Store or Apple Authorized Service Provider (AASP) for diagnosis.
For built-in displays
Try these steps to resolve the issue:
Make sure that the power cord is plugged into a working wall outlet, and that it's properly connected to the power adapter. (To check if the wall socket is working, plug in a lamp or other electrical device.)
Make sure that the power adapter is properly connected to the power port on the back of the computer.
Reset the computer's parameter RAM. (Click the link for instructions.)
On an iBook or PowerBook, reset the computer's PMU. (Click the link for instructions.)
Next we're going to check to see if the computer has video when started up from a disc:

Power Mac G5 won't restart after installing 10.4.10 update

Good Morning,
Last night I finally updated my Power Mac G5 to Tiger. That went just fine and I verified that everything was still functional and I could still connect to the web via my DSL. No problems yet...
I then downloaded the 10.4.10 update from Apple and installed it. When asked for Restart or Shutdown I chose Restart. The beginning of my problem. Upon restart I got the chime and the grey screen with the apple logo followed by the spinning stopwatch icon. It just kept spinning...for like 20 minutes. Then the fans started to wind up louder and louder and the spinning stopwatch icon stopped in it's tracks. I shut it down. It happened again.
Suggestions?
Trying to start from a disc (while holding down the "C" key) didn't seem to work any differently and wound up at the same result. Ironically, it just came out of the extended Applecare warranty this past February.
Thanks for any suggestions in advance,
Jim

So you can't use Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk? It won't get there? If it does, does your drive show up, and what is it's S.M.A.R.T. status please?
You could have some directory corruption. Let us know what errors Disk Utility reports and if DU was able to repair them.
Cheers!

Power Mac G4 Won't Boot after Installing 2nd Hard Drive and Additional RAM

Hello. I am using a Power Mac G4 (PCI graphics) that I bought a few weeks ago. It was working perfectly fine until I tried to add an additional hard drive and add more RAM to the machine. After I closed the case and plugged it back in, it won't start up at all. No sound, no lights, nothing spinning, nothing. I removed the added hard drive and RAM, but it still refuses to start. I don't know what happened. Hopefully it's not a logic board failure or anything else equally bad.

Welcome to Apple Discussions!
The PowerMac G4 PCI forum is over here:

I'll ask a moderator to move your thread. Try replacing the clock battery, and hitting the CUDAS switch.

Power Mac G5 won' Start Up

Power Mac G5 (bought in 2005) won't start up. Power Cords and plugs have been checked,House fuse box is Ok because other computer on the same power strip goes on as well as my printer. Press the power button nfor the G5 and nothing happens. I was able to use it on 5/5/13 powered up and shut down normally. Need help in trouble shooting.

OOPs, you marked it answered/Solved, might repst to get more helpers looking at it.
Is there a Red LED lit on the logic board?
If not then there is no 5V DC to start up.
Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & can cause strange startup problems...
See which one your G5 has...

Power Mac G5 Won't Connect to Linsys Router via PC

Greetings, I'm running a Windows XP Professional machine that is hard wired to a cable modem and connected to a Linksys Router (the WRT54G). I have a Power Mac G5 in the basement(running Panther) that recognizes the router but won't allow me to connect to the network, claiming I'm entering an invalid password. My original problem started without having the external airport antenna, but I received that today and still, no signal. The PC also recognizes an internal IP address beginning with 192... and the Mac recognizes one beginning with 169....anyone have any suggestions? I'm pulling my hair out of my head. Thanks.

Power Mac G5 Mac OS X (10.3.7)

sorry..you do have the configuration right. i think i'm having problems with both. i've been on the phone with Mac, Linksys and Microsoft for the last two weeks and no one can seem to figure out the problem. I took my G5 to an Apple Store, had the card tested and it worked. I've also connected the internet directly into the Mac and through the Router via Ehternet and that works.
I set the PC up with the Linksys software and created a Network---though, I can't seem to locate it on the PC. My Mac recognizes the Networks there when I click on the Airport Icon in the upper right hand corner, but tells me my password is invalid-same if I use Network Setup Assistant. If I Create a New Network through Airport and choose the Router's Channel, I get an Airport Window that shows full signal strength, but there are no lines in my Airport Icon in the upper right hand corner of my desktop, but rather a small box that looks like a mini TV inside the icon. Bizarre.
That is my dilemma in a nutshell. And as I said earlier, both machines still have Internal IP addresses. If I try and configure on the Mac Automatically, I get zilch. And the maddening thing is that I was actually able to get online about two weeks ago when this nightmare started..I didn't get past my Home Page, but I got on. Hope this clears it up a bit. Thanks.
