Resetting PMU in June 2004 G5

I've got the dual 2.0 G5, June 2004 edition. I'm trying to find the proper procedure to reset the PMU. The Apple support pages show resetting the SMU in Late 2004 models, but I can't find anything for the June 2004 edition of G5.
Thanks,

Well - the practical test tends to be - has it got a reset button as shown in the photo here

If so, use the second procedure.
If not, use the first.

Reset PMU/SMU on June 2004 Power Mac G5

Hello!
Does anyone know if the June 2004 Power Macs qualify as "early 2004" or "late 2004"? Specifically, does it have a PMU system or an SMU system? The Apple docs only seem to address the early/late 2004s when talking about resetting power management . . .and I don't know whether I have to open my Mac up!
Thanks for your help.

Hi. Well - strictly speaking, there isn't an "Early 2004"
http://support.apple.com/specs/powermac/
just the "Original" (no date in brackets)
But, as it's not a "Late 2004", it should have a PMU button as shown in the photo

But best to have a quick look, really.
Good Luck.

Dual G5 2.0 Power Mac (June 2004) referb - booting problem

Hi all - my dual G5 2.0 Power Mac (June 2004) decided to rev its fans and boot no more. When I push the power button in front, the white light comes on while pushing it, then goes off, yet I hear the fans starting, the hard drive spinning etc. The key board isn't getting power (the caps light doesn't go on) and after a few minutes the fans rev like a jet engine...starting slow then gaining speed. I can't open the DVD from the key board (have tried all usb ports). Have also looked through this discussion area and tried many of the solutions provided (reset the PMU, unplug, try different outlets etc.) Any help would be appreciated. I do have Applecare but they are closed for the night.
Thanks for you help
Dual G5 2.0 (June 2004) referb from Apple Mac OS X (10.4.6)

Your OS is not loading and the fans default into a speed up mode.
Power up and hold down the mouse button, the cd tray will spit. Insert Tiger/install disk and power boot holding c. (note: use a wired keyboard/mouse directly to the machine and nothing else for now)
In the Installer, select Disk Utility from the menu>Repair disk/permissions. note any errors you see.
If you can't access the drive, it might be dead. I hope you backed up files.
All you need to do is get a new drive and reinstall Tiger etc.
If you can get a 6 pin firewire 400 cable to each Mac and t boot the problem Mac. the hard drive should appear on the other which you can recover files.
If the OS is fried you can do a archive and install too.

Power Mac G5 dual 2.0ghz (late june 2004) - trouble upgrading video card

Hi, I'd really appreciate any help. I have a PowerPC G5 Tower, dual 2.0 GHz, DVI/AGP version (June 2004 model) with 8gb ram. I recently got the Apple 30" monitor and wanted to run it along side my 20" apple monitor, so I bought the ATI Radeon 9650 dual dvi video card (ATI-G5-9650 Power Mac G5 ATI Radeon 9650 Supports 30" Display 256MB (DVI/DVI) (8X AGP) Video Card). I pulled out my previous video card from the AGP slot and inserted this one into the same slot. I turned on the machine and plugged in both monitors to the dvi ports and both screens were blank when I booted. I tried plugging in only one of the monitors, but again, just blank. Does this mean the card is bad? Did I put it in the right slot?
Any advice would be helpful. Thanks

I'm installed an update, not 100% if it was the correc thing to update, but it was all I could find. I went to the ATI site and downloaded the ATI Displays 4.5.7.dmg and installed that as well as the ATI 10.3.6 SW Update.dmg. This was from the ATI site at: http://ati.amd.com/support/driver.HTML
Is there another place or something specific for the 9650 that I need to download?
thanks

Powermac G5 1.8Ghz June 2004 won't boot anymore

Hi all,
Past week i've bought a second hand PM G5. At first it seems to be all ok, but right now its not working anymore.
I've managed to install the OSX on the first evening i've had the PM G5. After installing evrything seemed to be fine. But after 30 minutes surfing on the internet, it froze. I had to give it an hard reset by holding down the power button.
After turning it of, it won't boot anymore. after a few times trying with 10 secconds between it, i unpluged the powercabel for 2 minutes. Wile turning it on after 2 minutes, it was booting , but it stopped booting after 1,5 minute and froze.. after hard resetting it, i've managed to boot it right. The OS seemed to be ok again, but after 5 till 10 minutes it froze again.
Right now it won't boot anymore... it starts (without the front light, this light only blinks fast once i turn it on, but after that no more. Sometimes it won''t even flash.
I've been buzzy replacing some components to get to know if it was a hardware fail. I've first replaced the PSU with two other PSU's from the PM G5, but won't do a thing.
The i've replaced the memory with 4 kind of difrent pairs, but won't do a thing either. At last i replaced the Logic Board, this won't even do a thing about it.
Of course i replaced the PRAM battery first, but also this won't help me.
I've tested it in AHT, but evrything was working well, according to AHT. I've managed to get the system log, but nothing scarry though here also, only some 122 errors some times. (download the system log here: http://www.mijnbestand.nl/Bestand-F4DDN66WLRCI.log )
I've reset al things possible like PRAM reset, PMU reset. Nothing seem to be working.
What can i do next to get this thing work?? I'm getting nut's here..
Please help..
Thanks a Lot

Hi martijnsnoek, and a warm welcome to the forums!
Can you count the beeps or flashes?
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
5 beeps = processor is not usable
In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.
Note: In this case, a flash is considered to be 1/4 second or 250 ms or greater in length.
http://support.apple.com/kb/HT1547
So, with the info you given, two things come to mind...
Bad solder joints around the RAM slots, try heating that area with a Hair Dryer for 3 to 5 minutes, then see if it starts.
If you can get it running, Get Temperature Monitor to see if it's heat related...
http://www.macupdate.com/info.php/id/12381/temperature-monitor
And/or iStat Pro...
http://www.islayer.com/apps/istatpro/
If you have any temps in the 70°C/160°F range, that's likely it.
BTW, have you blown the dust out of it since you got it?

ISight camera can't be recognized. Do I have to reset PMU?

Can anyone help me...?

nieyihemu wrote: ... iSight camera can't be recognized. Do I have to reset PMU？
Perhaps.
• If you have not already done so, restart Mac and
    try again. If the iSight still does not work, continue.
• If Apple's http://support.apple.com/kb/HT2090
   suggestions do not help you, (be certain that you
   use the correct PMU/SMC "reset" procedure for your
   Mac model), yours may be a hardware problem
   that will require a professional fix.
• Test more than one Apple app in more than one
   user account. If the problem persists with all,
   Unless you have a current backup, make one now.
Then use the final "Troubleshooting" suggestion:
"... contact Apple or an Apple-Authorized Service Provider for service."
• If you want to try one more thing on your own first,
use Disk Utility to repair permissions. Then
download and apply the latest Combo Update for
your OS. Currently, the latest SL Combo is here:
    http://support.apple.com/kb/DL1399
• Repair permissions again immediately following the system restart
   that completes the Combo update.
Properly applying the Combo version of updates can sometimes correct software problems, but, if your trouble is caused by a hardware problem, there are no user serviceable parts of iSight so see your AASP if the Troubleshooting suggestions don't work.

I NEED TO RESET PMU & RESET PRAM...HOW??

hello all...i was on the phone with applecare and i was told i have to reset pmu and rest pram...somehow last night i lost safari, deleted it, and tryed to download again and when i tryed it said "you can not install safari 1.2 on this volume. This system can not use this software"...i am new to apple so i have no idea what i'm doing..anyones help would be GREATLY appreciated!
thanks!

Hi,
Safari 1.2 is for OS X 10.3 (the previous version of the operating system according to your profile). If you are using 10.4.2, try installing the 10.4.2 combo update which should re-update your Safari to the correct version.

Blue screen, reset pmu, booted up, now no cursor

hello all...i have received a ibook g4 with some issues. i rebooted it, terminal blue screen, decided to reset pmu, came up after power up, and now no cursor. i tried to plug in a mouse. still nothing! any ideas? just trying to get the ibook back up to get the hard drive emptied off. thanks in advance.

Hi.
Two things to try for starters:
First , try a Starting up in Safe Mode
Safe Boot takes longer than normal startup
What is Safe Boot, Safe Mode.
Then re-boot normally.
If the above doesn't fix things so that you can "...get the ibook back up to get the hard drive emptied off" try booting into Target Disk Mode by holding the 'T' key down at start-up and connect it to your Pro with a firewire cable. The iBook's HD should show on the Pro. Run DU from the Pro to erase the iBook's HD. Use the zero out option (once will be enough) to map out any bad blocks. If you are re-installing you can run the install from the Pro too while the iBook is still in TDM.
Have fun,
Adrian

Reset PMU Xserve

Got an XServe intel version. Trying to reset the PMU as the fans have gone crazy. Had an engineer look at it, given the all clear but the instructions we've found are not at all clear and don't actually make sense.
*+1. In order to enter the headless command mode, hold the identifier button while you power the Xserve on.+*
*+2. Keep pressing the identifier until you see the top row of blue lights on the Xserve blinking.+*
*+3. Stop pressing the identifier button. You'll notice that the right-most blue LED on the bottom row is lit up - this indicates that the system will start from the system disk.+*
*+4. At this point you can press the system identifier button in order to cycle through the boot options. They are as follows (right to left)+*
*+- System Disk+*
*+- Network Boot+*
*+- Start from leftmost drive+*
*+- Boot next disk (other than startup disk)+*
*+- Target Boot Mode+*
*+- Reset PMU+*
*+5. Release the button once again and the system will boot into your desired mode.+*
We can get it to the 4th step and light up the PMU reset light but we would have already released the button to select that option! It then just sists there and doesn't reboot. If you power down and restart it starts normally again!
Any ideas? (Can't reset on MB as we can't access the server without serious surgery in the cabinet, it's not on rails)
Thanks.

Hey Ken,
If you are looking to reset the pram or nvram you can do so with sever monitor on a remote machine.
In server monitor you can click on the restart button and then select "on the next restart" Reset NVRAM and then select the first bootable drive.
It sounds more the like the system management controller is what you are looking for though as it controls the fans.
Follow these instructions for tha
1. Shut down the computer.
2. Unplug the computer's power cord.
3. Press and hold the power button for 5 seconds.
4. Release the power button.
5. Attach the computers power cable.
6. Press the power button to turn on the computer.

Reset PMU worked.... but....

The screen has darkened again. I will try resetting PMU again, however, I am concerned that at some point this won't work.
How do I determine the cause of my monitor going dark (hard drive is running but monitor remains dark)? This computer suits our needs just fine, so I'd like to keep it going as long as possible.
If fixing is cost-prohibitive, can we hook it up to an external monitor?

Unfortunately the troubleshooting in the Apple Service Manual is basically willy-nilly board changing until it works. I don't even think Apple is sure what the cause is and I believe the problems and expense of fixing was a driving factor for the iMac G5 not having such a complex neck arrangement.
You can connect an external display.
For a 700/800MHz iMac you can connect a VGA display of either 1024x768 (15" iMac G4 models) or 1440x900 (17" iMac G4 models) other resolution displays are not recommended as Apple crippled the video card.
For a 1GHz, 1.25GHz iMac you can connect either a VGA display or any video device (like a TV) via S-Video or Composite Video. Again 15" iMacs should have 1024x768 external display, 17" iMac G4s a 1440x900 external display or 20" iMac G4s a 1680x1050 external display.
There is a hack to remove Apple's deliberate crippling of the graphics, but it is risky (although I've never heard of a failure). This would allow an external display of pretty much any resolution up to about 23"/24" models.
iMac G4 (Flat Panel) 1GHz/1.25GHz:
Mini VGA - VGA
Mini VGA - Composite/S-Video
iMac G4 (Flat Panel) 700/800MHz models:
Mini VGA - VGA

Reset PMU... mouse still stuck..now what?

Hi,
I fixed logic board problem and graphics
Tried to fix mouse by resetting PMU
Now the computer (when you start it) grey screen with apple comes up and locks when the whell at the bottom comes up. Any suggestions?

I'm wondering if you inadvertently disconnected the trackpad somehow? Is it still not working? If it isn't, here is a link to Michael Baker's detailed instructions on how to reconnect it (in case that is the problem):
http://discussions.apple.com/thread.jspa?messageID=1034519#1034519
Does it work okay with a USB mouse?
Will it start up from the Panther Install CD by putting the Install CD into the tray and holding down the c key at the end of the startup chime? If so, then choose Installer > Open Disk Utility and select the hard drive in the left column. Choose the First Aid tab. Click Repair Disk to test and repair the hard drive.
Once you have repaired the hard drive with the Install disc's Disk Utility, then try to start up normally and repair permissions from Disk Utility in the Utilities folder on the hard drive.

Can I use 970fx cpu (June 2004 G5) in an original 2003 G5?

I have a functional 2003 G5 dual 2GHZ (970)(missing one CPU, so really a Single 2.0GHZ).
I also have a June 2004 G5 dual 2GHZ (970fx) with the dreaded logic board issue.
Can I install the two 970fx CPU's from the 2004 unit into the 2003 unit?
Thanks

Hi GMcIntyre, and a warm welcome to the forums!
I'm betting not since G5s are so special in CPU to Logic board combo,s one uses the 970, the other the 970fx...

3d card options for June 2004 Dual 2.0mhz G5: Redux

Hi! Back in March, I posted an inquiry in this archived thread and got some good responses...
http://discussions.apple.com/thread.jspa?threadID=893370&tstart=0
Except that the recommended card I have since then waited and waited to order, without any sign of it ever being released! Is there now a better answer to this question, or perhaps does someone know anything else about this card's shipping delay? Original inquiry was:
Hi; I have a June 2004 Dual 2.0mhz G5, and I'd really like to upgrade its graphics card, to get the most I can out of the now-aging machine. I really have little idea what my options are, so I'm throwing myself on the expertise and advice of any here who may have a thought.
Currently it's got a Chipset Model: GeForce FX 5200 (64mb) on the 8x AGP bus. I know I have PCI slots, but my hunch is that I will get better options for the DVI out if I stick with AGP. I don't even know if a standard-issue AGP card for the PC will work. I don't know whether to try for ATI or nVidia (ATI looks like it only has 'special edition' cards for the Macs and I don't know that I trust the drivers). So I guess I'm looking for subjective, biased advice from someone who knows the lay of the land. I'd like to get as much RAM in the new card as I can. I use it for gaming, though I do some 3d work with program s such as SketchUp or ZBrush.
Sorry this is so vague. Any advice is appreciated, though.
Thanks,
Heath

Hm; if no word on that card [the ATI X800], does anyone have a recommended alternative?

Heath, not vague at all. AGP is your best option by far. That said I'll be honest and tell you that you're going to have a hard time finding one of the better cards. I'll rank the options from lowest to best.
1 Radeon 9800
2. nvidea 6800
3. Radeon X800 - the best
you need a mac specific card. I would stay away from flashed pc cards because of possible compatibility issues.
I would keep an eye on http://eshop.macsales.com/shop/video/hardware/ for cards. Be very careful if you decide to go the ebay route...many sellers are selling flashed pc cards.
