MDD G4 (Dual 1.0ghz) Won't go to sleep...

Hey all,
I've got a weird problem where all of a sudden, my G4 MDD won't go to sleep! it's been working fine, and I haven't changed or installed anything in the last few weeks. Selecting sleep from the apple menu doens't do anything.
I thought it might be a pram problem, since my clock was always getting messed up lately, when I rebooted, it would always say it was out of synch and at a really old date. This problem is now fixed, but I still can't put the computer to sleep.
Could this be a battery problem? Is there any way to check?
I'm running 10.4.8.
Any thoughts would be appreciated.
Thanks!

This is for a Mac that won't sleep.
First, read things in Apple doc.#25801 on sleep settings.
USB devices and hubs often cause Macs to not sleep or wake quickly from sleep (notably HP printers and scanners, HP all in ones, and Cannon scanners). Disconnect all USB except for keyboard and mouse and try. If it sleeps, add one back at a time testing after each one to find the culprit.
If you've set your Mac to recieve faxes, it may not be able to sleep. It might also have a damaged preferences file.
If you use your Mac for faxing, open System Preferences. click Print & Fax, click the Faxing tab, and uncheck the Recieve Faxes On This Computer box.
If that does'nt work or you've never faxed on your Mac, go to Finder/Hard Drive /Library/Preferences/SystemConfiguration and delete the com.apple.PowerManagement.plist and com..apple.AutoWake.plist files (if your Mac asks, type your admin. password).
If the latter file isn't present in the folder, go to user name(probably your name)/Library/Preferences, delete the com.apple.systemuiserver.plist file, and reboot your Mac.
Hope this helps!
P.S. One member here reported this (Michael Gleason);
"I have had this problem with my IMac G5. It is surprisingly irritating. LaCie's Silverkeeper backup software was the cause. By default it gave itself permission to wake up the computer to check if a backup was needed. Do you have this or a similar program installed which has scheduled activities including wake-up permissions as an option?"
Dave Hamilton provided this link, xlr8yourmac.com, to a member, which addresses failure of deep sleep with some users that updated and added new FireWire and USB cards.
tomhorvat adds this; After few days of messing around I found out that I had desktop background (wallpaper) set to change every 1 minute.
After unchecking "Change picture..." in system preferences (under Desktop/Screen saver), my powerbook went to sleep all by itself.
Cheers!

G5 dual 2.5 won't go to sleep

Won't go to sleep. I have to shut it down and reboot everytime. It becomes unresponsive and the fans run. I've reset the SMU and PRAM, no good. Any suggestions??

Dual 2.0GHZ won't boot, help?

I have a Power Mac G5 Dual 2GHZ, I believe the first late 2004 model. It had 3.5GB's of RAM and an older model Apple Cinema display.
The problem is, is it just wont boot up. I turn the power on, the screen remains blank and the light flashes on the computer 3 times. I consulted the manual and it says that if the light flashes 3 times, the RAM is incompatible. However I took out all 8 sticks of RAM and tried each pair for a boot, but none of the pairs would but and I received the same 3 flashes. I should also add I tried resetting the PMU and it didn't solve the issue. It doesn't boot so resetting the PRAM also is a no go.
Everything powers on properly, so I'm don't think its the PSU, unless you know different. I'm not sure if all my RAM has died, if its the Power Supply or Perhaps the logical board has failed? Or maybe something else?
Any help would be greatly appreciated, thanks.

Any idea what might be charged to have someone to replace motherboard?
I'm having the above problems starting shortly after I installed Leopard. The Mac is unusable now and in the shop. I became concerned though after the Apple authorized Tech guy gave my machine a 20 minute lookover and didn't have a clue. Talk of motherboards and power supplies came up. I know both are expensive not counting labor.
I bought a used 2.7 ghz. G5 this morning. Maybe it's premature but at least I get a better machine that will be working, here in a few days.
I'm out cash but I struggled for days trying to figure my Macs problems out. The nightmare is over. For now...

Sick dual 1.0Ghz MDD

I inherited a snazzy dual 1.0ghz G4 MDD and am having trouble diagnosing it's ailment. It chimes when powered on, I can hear the HD spin up, but after about 8-10 seconds the fans spin up to full speed, nothing comes on the screen at all and the fans just continue to spin at full RPM.
One of the processors has a small amount of brown goo caked on near the die (not on the surface, just next to it - similar to the goo that oozes from a capacitor that's blown) and I was able to remove all of the crusty thermal paste and reapply new paste but the same thing happens when I try to start it up. I know little of the machine's history except that the person who owned it was attempting to install the OS at the time it crapped out.
If anyone has had a similar experience or knows what might be wrong please lend a hand. I'd like to be sure of the problem before I rush out and but a replacement MB or CPU.
Thanks!
Dual 1.0Ghz MDD Mac OS X (10.4.8)

Ewww...sounds bad. I've had that happen once. You see, the fans are controlled by the CPU's temperature, and the faster they move, that means the hotter the chip is. Also, that dried out thermal paste was either caused by, or the cause of your problem, as it is either a sign of excessive heat or non adequate heat protection. Sorry to say this, but I think the CPU is fried. That explains the rapid acceleration of the fans. I COULD be wrong, but that is normally what the syptoms describe. I'd have it checked out by a mac genius, as he can give you a more definate answer. If that's the case, you're gonna need a new CPU, or maybe a new logic board.

G4 Quicksilver Dual 1.0Ghz...Louder then MDD Dual 1.25???

Hey Guys,
I have an odd question. I have a MDD G4 Dual 1.25Ghz and 2 QuickSilver G4s one a 733 and one a Dual 1Ghz.
The MDD G4 I was always told and remembered that they where loud wind tunnel machines, and made lots of fan noise. My MDD however barely is audible its great (Im sure it has the revised fan and PSU)
My 733 is also quiet, makes barely a noise. Now my Dual 1Ghz, thats a loud machine, its not really a pitch, it just the sheer speed the fans are moving, as if the machine wasnt designed for dual 1ghz processors to sit in it.
I even swapped the processors since the 733s case was in better shape, and still the fans are always loud.
Any fixes for QS cooling VS MDD which is all the stuff I can find?
Thanks all

Hi-
Replacement of the thermal pads with MX-3 or MX-4 thermal compound will increase the cooling efficiency and help reduce fan noise.
My DP 1 GHz QS quieted noticeably after thermal compound application.
http://www.jcsenterprises.com/Japamacs_Page/Blog/9AE7FE0E-0CF2-4A7C-8003-489B282 582BC.html
The PSU fan in the QS can be a major noise maker, and replacing that fan with a quieter fan can really help.
A 4,000 RPM Verax (Globe Fan, distributed by Zaward) cools much better and is much quieter.
The 80 mm Vantec (TF8025) is also a very good option:

Use the Vantec TF6025 to replace the CPU fan for help there.

It will not run on Mac OSX 10.5.8, on a G% dual 2.0ghz, now my older version of Firefox is gone...

I downloaded Firefox 4.0 and It will not run on Mac OSX 10.5.8, on a Mac G5 dual 2.0ghz. Now my older version of Firefox is gone...Why won't it work, the download page says it is for OSX and does not say it will not work on any particular OSX. Can your clarify. And can I get the old Firefox 3 back or should I continue using Safari....?

Yes I've read every one of them, none of them provide solutions whatsoever, I have spent about ten hours on this site in the past two days to no avail, none of the "resolved" threads provided any sort of solution for me, I have tried everything suggested on this website so far, multiple times, to no avail.

Mac Pro Dual Quad Core won't boot OS/X, but plays fine with Linux/Windows

I've got a Mac Pro Dual Quad Core won't boot OS/X, but plays fine with Linux/Windows. I've tried all of the following initial tests as suggested on forums:
-Ram swaps
-Alternating video card in PCIe slots
-Trying alternate video card
-resetting pram and smc
-Multiple tests with memtest86+ over 26hrs and no failed ram
-Multiple tests (8-12 cycles) with apple HW diagnostics and no problems
-Firmware is approved firmware for early 2008 model...no new updates.
Gentoo livecd works fine and I even installed to hard drive and it boots fine with it. In addition to above tests I also ran a linux stress test putting all 8 cores at a load of 22 for 2.5hrs with no problems.
Memtest86+ for 24hrs+ yields no problems.
Where problems occur:
Booting off hard drive, DVD or firewire yields an immediate curtain of death and booting off a new snow leopard DVD dies about 25% into the install.
Looking at error log and a quick dmesg shows "Package 0 didn't get an HPET" and complains about AppleIntelCPUPowerManagement.kext. Google turns up illegal uses of this, so doesn't apply to my use case.
I'm a bit stumped since all was working well until one day it was non-stop curtains of death and can't get them to go away.
A logic board replacement at $1100 is not a feasible option for something that works on linux and windows, but not OS/X, is a bit disappointing and somewhat surprising.
Thanks for your help and advice.
Regards,
Marcos

Someone here once thought they knew EFI and Open Firmware a little, and used some commands from OF library that an Intel EFI Apple system didn't like. New logicboard.
Of course to run or boot OS X and see video you need EFI based card. The presence of some PC cards can block OS X from booting.
The fact you get part way through SL DVD, pull all the drives, put in a new drive and format it from SL DVD.
Most of the things you tried are what are more common with PC hardware. Including where people have tried and failed to install OS X on unsupported hardware.
I suppose it is possible something tried and failed to modify the Mac's firmware.
If you have Windows running, and you have WD drives, WD just posted new Lifeguard utility which is what I use to do a good job of stripping a drive down and recertify it for reuse, works wonders. Maybe same for other makes with vendor utility.

G5 dual 2.0Ghz bought in 2003+ 30" cinema display?

Hi all.
I bought the first generation G5 dual 2.0Ghz in 2003 and am sure that I have Radeon 9600 pro video card installed in the computer. Currently, I am thinking of buying 30" cinema display and did some research on it's specification.
I found that Radeon 9600 pro: pc/mac edition is compatible with the monitor, but I am wondering if the 9600 pro version can support the monitor.
If it can't, would anyone like to recommend a good graphic card except 9600 pro:pc/mac edition? Ugrading from original 9600 to 9600-pc/mac edition just sounds like a waste of money because of their similarity of specifications.
Any responce would be greatly appreciated,
Thanks..
KYE

To find out if your Mac already supports a 30" 2560x1600 resolution, go to the monitor resolution icon at the top of your Finder/menu bar on your desktop. Click on the icon and explore the various resolution possibilities. If they go all the way to 2560x1600 your good to go. No need to buy another card.
Unfortunately, I purchased a similar model in '04 and it does NOT include a sufficiently good enough graphics card to power the 30" [I was told by the apple dealer in '04 that it did. It doesn't.]
My research in to graphics card options for 'our' situation is as follows:
Low End: Radeon 9600 Pro Mac & PC Edition [$199]
Mid Range: Radeon 9800 Pro Mac Edition* [$250]
High End: Redeon x800 [$399]
I don't think the Rad9800 can drive more than 2048x1536. This might be satisfactory for you, it's not quite the maximum of 2560x1600, but your menus will be a little bigger at 2048x1536
Good luck.
My question to no one in particular is: did all early PowerMac G5 towers ship with AGP 8x slots? or 4x slots? or what?

Jumper Settings for Second SATA-II drive Installed Into Dual 2.0Ghz G5

I have installed a second SATA-II 500GB Maxtor drive into a brand new (purchased as re-furbished computer from Apple) dual 2.0Ghz PowerMac G5. The drive has four connector pins with a jumper slide over the last pin on the right. Before I power up the computer I want to verify the correct jumper settings. According to the Maxtor website, no jumpers are required since the "serial ATA host automatically determines the master and slave hard drive." And according to a MacSales tech (this is the vendor where I purchased the Maxtor drive) I should pull off the existing jumper. Can anyone verify if this is, in fact, the correct jumper setting (no jumpers on the connector pins) for this drive on this system?

Hello! From the Maxtor web site.
"PLEASE NOTE: Unlike standard ATA drives, Serial ATA drives DO NOT require the use of jumpers to configure the drive. Please disregard any references to jumper settings and Master, Slave and Cable Select configurations in the Maxtor Installation Guide."
I'd leave the jumper as is came when you got it. tom

1.8Ghz & Dual 2.0Ghz Logic Boards/Power Supply

I have a perfectly fine working 1.8ghz G5. I also have a dual 2.0Ghz G5. However, the dual doesn't power up. I'm pretty sure it's the power supply. But, I'm not positive.
My question is. Is it possible to put the dual 2.0 logic board into my 1.8ghz machine? The inside of the cases look very similar. Or is there a way to test the logic board of the 2.0 before I take everything apart?
Thanks..

The CPU speed of a PowerMac G5 is always 2x the bus speed or less. Thus, with the 900 MHz bus speed of the 1.8 GHz motherboard, your 2.0 GHz CPUs would clock down to 1.8 GHz at best.

Is there much difference btwn dual 1.8ghz and dual 2.0ghz

Hi,
I have seen a dual 1.8ghz (M9454LL/A) second hand with this spec:
Machine Type: Power Mac G5
Machine Model: PowerMac 7,3
CPU Type: PowerPC G5 (2.2)
Number of CPUs: 2
CPU Speed 1.8GHz
L2 cache (per CPU): 512KB
Memory: 1.25 GB
Bus speed: 900MHz
Graphics Card: GeForce FX 5200
ATA Bus (DVD): Pioneer DVD-RW DVR-117D
Serial-ATA (hard-drive): Maxtor 80GB
for a good price around £800 which would leave me with money to buy a monitor.
This model already has airport built in and additional ram added.
I am a music producer (running digidesign protools LE) and need a studio computer to see me through the next couple of years. I have been looking at getting a dual 2.0ghz machine but these are invariably more expensive and I would have to pay to add the features this model already has, as well as purchasing a flatscreen.
Basically I want to know how much of a performance difference i will see between a dual 1.8ghz machine and a dual 2.0ghz machine.
cheers guys

Ok that dual 1.8 is not much difference from a dual 2
Your dual 1.8 has a 900 Mhz front-side bus per processor
The dual 2 has 400 more Mhz total in CPU speed (not much really) and a 1000 Mhz frontside bus per processor.
So the difference is minimal.
You could upgrade that video card to a AGP ATI X800 and 3D game all the latest ones with no problem. (I would before they are all gone)
If you get yourself another internal hard drive, something large like a 250-300GB SATA and keep your user files in there instead of on the 80GB Maxtor, your performance "feel" would be pretty good as well. (no Western Digital, they upgraded their SATA specs)
And you got a Superdrive, so you can burn dvds.
If time doesn't equal money, and your not constantly pushing your CPU's day and night, this machine is a good buy IMO. You should get a good 3-4 years out of it, especially if you know when to stop upgrading the OS/apps.
Yes I say you got yourself a good buy there.

Bluetooth in Dual 2.0ghz

i have a dual 2.0ghz powermac g5, the one with 4 ram slots. i want to get bluetooth in it and i wish i would have just had it installed when i first purchased the computer. Well hindsight being 20/20 what is the best, not easiest way, to get reliable bluetooth in the powermac. I don't mind installing an internal card or anything i just can't find any howto information. thanks in advance.

Restart with the Option key held down and see if the internal drive appears.
If it does, click on it, press Enter, and then change the setting in the Startup Disk pane of System Preferences or the Startup Disk control panel.
If it doesn't, insert a Mac OS install CD or DVD and use the Disk Utility or Disk First Aid to repair the internal drive. If there aren't any problems, install an OS onto it.

Dual 867mhz MDD G4 & Dual 1Ghz G4 Quicksilver: Near Perfect Installation

I installed the family pack on both my desktop G4 towers (Dual 867mhz MDD G4 & Dual 1Ghz G4 Quicksilver) and had almost ZERO problems.
I opted to upgrade my OS X 10.4.10 systems.
Both installations (upgrades) were without a problem, except for one minor keychain glitch:
MDD Dual 867mhz G4: After installation and restart, the keychain seemed to have forgotten my passwords for my POP email and my iChat (AIM) accounts. I simply cleared the keychain (as prompted) and re-entered the passwords (opted to save them) and all is well.
Quicksilver Dual 1ghz G4: No keychain issue. Passwords were retained just fine.
Every piece of email, settings, music, files, folders, apps, etc were all retained just fine on both computers.
All my Adobe CS2 suite apps, MS Apps are just fine.....as does my Final Cut Pro software.
The only software that "broke" was GOOGLE EARTH. I simply just downloaded the latest version and all is well again.
Approx. Install time: 1hr.
Note: If your computer stalls on a blue screen (my computers did this on TIGER install), let them go. More than likely it's "finishing" the installation and probably cataloging the hard drive for Spotlight.
This Leopard OS Rocks! I can't wait til they fine tune it with a 10.5.1 update release

I put Leopard on a Dual 800 and a Dual 400.
Leopard pushes the limits of the 400. The 800 runs pretty well.
I mean it is slower in some places, but I assume that will be fixed in updates.
(for instance... my cursor is sticking to links in firefox and it kills my CPU usage)
Everything else works great.

Whats the Largest Drive and/or Partition on G4 MDD/Fw800 dual 1.25?

Whats the Largest Drive and/or Partition on G4 MDD/Fw800 dual 1.25?
Hi, Protools user here, using my G4MDD/Fw800 and Macbookpro, i like of course to have interchangability, if i can.
1- Whats the maximum size internal partition my G4 can read? one drive of 750gig?
2- Whats the maximum size Fw800 Drive my G4 can read? one drive of 750gig?
2a is it the same for fw400?
3- Are there 2 separate internal buses on my G4 MDD?
I just bought a 500 gig hitachi, IDE, popped it in an OWC fw800 case and was having errors dragging huge folders from my g4's internal 233gb drive to the Fw800 on the external bus
Hope everybody understands my questions. Appreciate some help.
