Power Mac G4 Dead?

I own a Power Mac G4 MDD, and recently i had to adjust the usb ports as they were tilted, so i removed the heatsink and accidentally touched the processor when putting the heatsink back on and now when i turn it on there are a couple things that happen:
1. Fans and Red light on logicboard start up, display does not
2. After a while the fans kick up their speed
3. Does not shut off automatically, but power button fades
Help would be appreciated very much.

If you pulled the AC power cord out while you worked on it, your Mac may be suffering from a dead battery. It will tend to forget where the display is and what its resolution should be. It can also cause additional problems. I suggest you do a PMU Reset, and since your battery may be dead, to do it with the AC power cord installed.
From completely off:
Press and hold the tiny button on the motherboard nearest the battery for a quarter minute. Avoid momentary presses.
Wait at least five seconds.
Try to start up again.
If this fixes the problem, you should suspect battery problems with the 3.6 Volt 1/2 AA-size non-recharging battery. if you have not changed it in years (or ever) it could be time.

  • Power Mac G4 dead battery ?

    I am wondering if my battery is dead.
    I had stored my G4 Dual 1.25 GHz MDD for about 5 months while I moved to a new location and built my new recording studio. Upon powering it up it ran fine the first day (only had it powered up for about 10 minutes). The second time (a few days later), it was fine for 10 minutes, then the displays went off on their own (they weren't set to sleep). They would come off and on intermittently. When they were on, sometimes I had use of the mouse and keyboard and sometimes I wouldn't. After a few minutes of this they would stay off. Once they were off, the power button did not respond like it usually does. If I held it down or 5 seconds trying to power off, it would not respond. It didn't matter how long I held it, it would never power off. The only way I could power off was to pull the plug. After doing that, I restarted and reset the PRAM. It powered up and I had to reset the date and time. It seemed like it was ok for a minute, then the monitors went dark again, went on and off 3 or 4 times, then stayed off. The power button again did not respond normally.
    Is this all due to a dead battery, or is there another problem ?
    In the new studio, I did set up the G4 on it's side.
    I'm wondering if this had anything to do with it.
    any help would be appreciated.
    thanks

    Thanks or your help, Tom.
    I tried reseting the PRAM, and I also reset the PMU button.
    I think there is something wrong with the logic board.
    I will re-post with a new title.
    The heat sync is extremely hot, and the larger fan that is directed at the heat sync is not working.
    I just found this article when I did a search for power mac G4 fan: http://docs.info.apple.com/article.html?artnum=95038
    in that article, it mentions 2 LED's that should be either both on or both off, and there is only one of these LED's that is light
    <1. Power Macintosh G4 (PCI Graphics): Check LEDs DS7 and DS8 on the logic board. In a working unit, these LEDs should be in sync with each other: both on or both off. If one LED is on and the other is off, there is a problem.>
    any idea what this means ?

  • Dual G4 Power Mac is Dead??? Need HELP!

    Dual 1.25 G4 will turn on, fans amps up loud, screen stays black and no startup tone. I was on vacation and left it on by accident for 4 days with the monitor on. My brother turned it off for me using the monitor power button when he saw it.
    I am having issues very similar to this post: http://discussions.apple.com/thread.jspa?threadID=469582&tstart=0
    I have tried a deep reset, reset the PRam, battery voltage is 3.6 volts, reseated the Ram, processor, and video card, unplugged anything extra and just left it as stock. (by the way the processor heat sink is cold when it usually gets quite warm)
    But still no progress or response from the two displays (20" and 17" studios)
    I was thinking that I killed the video card by leaving it on for that long, but wouldn't I get a startup tone if the computer was still working?
    I don't want to spend $400 to replace the processor or logic board. I might as well spend that towards a new computer if this can't be fixed more easily.
    Thanks for your help.
    -Jake

    AirTahoe,
    As you see from my post it turned out to be the processor, however plenty of users have been able to solve the similiar problem with different techniques. Most of those issues are posted in my thread. Do you have access to another mac that you can swap parts with to test your processor, or perhaps an authorized repair location? Unfortunately I did not and ended up ebaying some parts (I recently seen a dual 1.25 on ebay that went for about $200) and ended up solving my issue. Let us know what happened.
    Did you try removing the battery, reset pmu, wait, start with no battery?

  • Power Mac G5 Hard Drive Dead?

    So the other day I tried to format my internal hard drive using my leopard server install disk that I bought for my power mac but I got the error Resource Busy. Then I used my Tiger install disk to format the drive and got the error Input/Output error. I ended up putting the hard drive into a PC I had and used it to format it to FAT. After that I put the hard drive back in my Power Mac G5 and it showed up as FAT and I formatted it to Mac OS Extended (Journaled). I took a 250GB drive I found and also stuck it into the G5. Formatted it into Mac OS Extended (Journaled) and tried RAIDing them together using a Concatenated Disk Set so I could get the full usage of my 250GB and my 1TB drives. The raid failed with a error I can't remember. Now the 1 TB drive won't show up at all. The PC says it is a unknown device and needs drivers. What do I do. I have tried everything I know. Do I need to buy a new drive (why couldn't it be the 250 GB drive )

    That drive series has had a bunch of issues.

  • "Dead" G5 Power Mac

    Looks like my faithful G5 Power Mac (2004, Dual 1.8GGHz) has called it a day! It does not start up and after a few minutes the fans rev up. I have tried all the recommendations made in this forum, to no avail.
    Please could any community members tell me if I can remove the hard drive from the Power Mac (Western Digital WD740GD) & place it in an empty drive bay of an Mac Pro (Early 2009) to access data on the hard drive, or will the presence of an Operating System on the removed hard drive cause a problem with my Mac Pro booting up?
    Thank you for your advise.

    Good news on that.
    Do you have another thread on the G5 problem?
    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...

  • G5 Power Mac Dead

    It's a G5, 2.0 dual processor Power Mac (2005 model year). One day recently it just wouldn't turn on. Nothing, nadda, zip, zilch! Looking for an easy solution I bought another power supply from ebay and still nothing (could also be a bad supply of course). I need to find a pinout diagram for this type of 600 watt power supply so I can do some tests. Any help in this regard would be appreciated.
    I'd be glad to receive recommendations for other forums where this question might be better addressed if this is not the best venue. -- Matt

  • Power Mac G5 Dual 2.5 freezes up, Power Mac G5 Dual 2.5 freezes up

    Hello
    I inherited a Dual 2.5 PPC Power Mac G5 from my sister. She was having problems with it suddenly freezing up. She replaced the hard drive but that didn't fix it, and sicne she had a newer Macbook Pro she gave up on it. When I got it I replaced the video card on it with an ATI Radeon, and it seemed to run fine for a while, and then the problem returned. It seemed to have returned after I did all the Apple software upgrades on it (It's running Leopard), but that might be a coincidence. I noticed under Diagnostics on the power up test that some RAM had failed. I also noticed that it was running on 1 gb of RAM even though 2 gb were installed. I removed the faulty Ram (4 256 mb dimms) and hoped that that was the problem. Unfortunately it wasn't. I also installed a temperture reading program. It showed that CPU A is running around 80 C at times and is usually about 10C hotter than CPU B. I'm not sure though if 80C is normal for a G5 or not. I noticed that when it was unplugged that it wouldn't retain the time and date, and took a look at the battery, and sure enough it was starting to leak (but hadn't leaked on to any components). I've ordered a new bttery for it.
    I ran a check with Disk Utility and found the HD was ok, but permissions were a bit messed up. Disk Utility wasn't able to fix some of the permissions, but i don't think this is the underlying problem.
    I've also opened it and gave everything a thourough vacuuming and cleaning and reseated any removable parts. I took the cover off the liquid cooling unit and vacuumed out the dust. There didn;t seem to be any coolant leaks I could see.
    Any suggestions on where I should go from here? I unfortuantely don't have any of the disks for it, so I can't run the AHT until I find one for it (the one for my Macbook Pro wouldn't work).
    Sometimes it just freezes. Other times it freezes and the computer fans go on high. It will finally get to a point where it shows the grey multi-language restart screen (where it says to hold down the button to shut it off and the restart).
    It was frustrating because on my workbench it was running fine after I switched the video card, and it didn't freeze at all. When I moved it to our computer desk though, the problems returned. Tonight it was to the point where it didn't last 5 minutes.
    My thoughts are:
    1. Maybe All the RAM is bad
    2. Maybe the dead battery is messing it up?
    3. When it is heating up with use, something is expanding and not connecting any longer.
    What are your thoughts?

    Hi Curtis,
    I'm not sure though if 80C is normal for a G5 or not. I noticed that when it was unplugged that it wouldn't retain the time
    Nope, not normal, way too hot, above 70°C... If you have any temps in the 70°C/160°F range, that's likely it.
    Have you blown the dust out of everything with high pressure air?\
    1. Maybe All the RAM is bad

  • Power Mac G4 Quicksilver Won't Wake From Sleep

    I have a Power Mac G4 Quicksilver 933MHz that will not wake up after it goes to sleep. It is currently running OS X 10.3, has had its hard drive replaced, system reinstalled, and been DiskWarrior'd. Haven't tried replacing the PRAM battery yet but get no indication its dead (clock keeps time wen off). It always connected to an Apple 17" Cinema Display--could that be the source of the problem?

    Hi, Toolshed4!
    Third Party USB devices and USB PCI cards are notorious potential culprits for no wake from sleep issues so please follow japamac's lead and look at them as potential culprits. Disconnect the external peripherals and test sleep/wake. Swap a third party keyboard and/or mouse with your Apple one(s) and test. Remove any PCI cards, and test. (It's perhaps good practice to reset the PMU after you add or remove an internal component.)
    A Cinema Display, especially one with a built-in USB port or hub problem, could create an issue, though it would more likely to be one of not sleeping, rather than not waking. You might quickly check your system log for possible indicators of USB issues with the Display, if you have reason to suspect that its ports may not be functioning properly.
    Resetting NVRAM in Open Firmware sometimes resolves the issue. Resetting your PMU as japamac suggested will take care of the NVRAM reset for you.
    If the above didn't resolve things, please continue on...
    Corrupt Energy Saver preferences are sometimes the cause. Quit System Preferences if it's opened and navigate to /Library/Preferences/System Configuration (folder) and delete the following preference files:
    com.apple.PowerManagement.plist
    com.apple.AutoWake.plist
    (The AutoWake plist file may or may not be present, depending on whether or not you have/had scheduled sleep settings.)
    Then navigate to ~/Library/Preferences and delete the com.apple.systemuiserver.plist preference file. Restart and test sleep again.
    If your battery is old, it's a good idea to just get a new one. The worst that can happen is that you'll have a spare when you need it. They're about $5 online. If you go to Radio Shack with the one you have, they'll test it for you. Alternately, put a voltmeter on it and insure that you're reading at least 3.3 volts DC. New ones read 3.6 - 3.9 volts.

  • Power Mac G5 Dual 2.5 - Move Hard Drive to another G5??

    Hi,
    I'm using a Power Mac G5 Dual 2.5 w/ OS 10.5.8 with my Pro Tools 7.4.2 HD3 rig, 2 internal hard drives and tons of external FW hard drives.  It's being hinky with me (every time I reboot/restart the Mac, I have to take the side cover off or it won't boot; wierdest problem ever), and being that I don't want to plunk down thousands of dollars on a new Mac and all new Pro Tools equipment, I'm hunting E-Bay for an exact duplicate of my Mac, of which there are plenty.  Since PowerPC architecture is long dead, they are dirt cheap.  No reason not to have a spare.
    My questions are:
    If I buy another Power Mac G5 Dual 2.5 machine, and swap the hard drive it comes with, and use my already functional hard drive (with the OS, Pro Tools and all related plug-ins installed), and move over my Pro Tools cards and 8 GB of RAM to the new(er) machine, will it boot up and work without me having to reformat/reinstall everything? 
    I also see numerous Power Mac G5 Dual 2.7 machines out there as well.  What are the chances of doing the same as question 1 with this?  I know the processor is different, but would my already formatted and functional hard drive care?  I don't think this will work, but I have to ask.
    If Question 2 is even possible, would upgrading to a Dual 2.7 even be worth it as far as noticeable speed improvement?  Superior Drummer, EZ Drummer and EZ Keys are all real time plug-ins that need the Mac's processor/memory to work. They don't use the Pro Tools cards to work.  So, would getting that extra 200 Mhz of processor power even matter?
    The reason I ask is that reinstalling the OS and Pro Tools is not the issue; 4 hours and it's done.  BUT, reinstalling Superior Drummer, EZ Drummer,and EZ Keys, along with the mountain of expansion packs, will literally take several days of work.  If I could just plop my old hard drives and 8GB of RAM into a newly purchased G5 Dual 2.5 or 2.7, and not go through that, it would be AWESOME.
    Thanks for any feedback on this.

    Just got done making the transfer to the "new" Dual 2.7 G5 I bought off E-Bay.  (yes, on Christmas Eve, because....well.... I have no life).  Worked dead, solid perfect!!!  I'm grinning from ear to ear right now.
    I had to reset some pref's in Pro Tools (not an issue),  Just got done running Pro Tools through its paces, and it works perfectly.  All plug ins run (had to re-authorize Superior Drummer and some related plugins because it detected the change in system serial #, again not an issue).  Other than that, it worked like it always has. I loaded every third party plug-in I could find, and every third party program I could find, and so far everything works without any issues.  Only exception is Team Viewer locks up when I try to close it (have to Force Quit), but I couldn't care less right now. I use that twice a year if that, and just to have someone help me remotely.
    Thanks for the info and help.  This made my Holidays.

  • Power Mac G5 wont boot.

    Hey everyone!
    This is my first time posting here, but I get all my technical problems solved here, so thank you to everyone!
    Anyway, getting on to my problem (which I cannot find a answer to)
    My Power Mac decided the other day it wasnt going to boot up. All that would happen when I pressed the power button would be the red light (on the logic board) would flash while I can the button pressed it, I would hear 2 clicks like a relay, and that was it. Nothing, it would never boot.
    So I switched the computer off at the wall, left it for 2/3 minutes, and all was fine, would boot and restart. But, if I shut down the computer, I would not be able to get it to turn back on, unless I switched it off at the wall again.
    I do know that turning it off at the wall resets the SMU? So would there be a problem with my SMU or something? No idea if that is even possible!!
    Can anyone shed some light on the problem? Just to let you know the computer was never droppped/banged/hit etc etc. I was on it, turn it off to pop out for a hour, came back and its been like that ever since
    Any help will be much appriciated!
    James

    Hi James, and a warm welcome to the forums!
    Not sure which Mac it is you have with the l essuseful new forums, but it sounds like the classic case of either a bad/low,/dead PRAM battery, or a leaking Capacitor.
    Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & if weak can cause really strange problems...

  • I have a Power MAC G5 dual 2ghz that has a peculiar problem.  The monitor will not report until the machine is stopped and started 5 or 6 times.  Once booted it will restart without problem if done so from the apple menu.  Swapped out all hardware

    My Power MAC G5 has a peculiar problem.  The monitor fails to report until the machine is started and shut down 5 or 6 times.  Once it has booted it can be restarted without incident from the Apple menu.  I have swapped out all of the hardware.  Monitor, Memmory,Video Card and reset the PRAM.  After resetting the PRAM it booted on the first attempt and I thought it was solved.  But the next day it was back to starting and stopping until the Monitor came on.  Does anyone have a suggestion?  Thanks

    It could be a bad PRAM battery corrupting your PRAM.  Typically when I have monitor issues on startup it is a bad PRAM battery.
    Texas Mac Man's PRAM, battery, PMU tutorial - https://sites.google.com/site/macpram/mac-pram-nvram-cuda-pmu-battery-tutorial
    Apple's PRAM reset directions - http://docs.info.apple.com/article.html?artnum=2238
    If you have a digital multimeter you can check the condition of your present battery.  It should read at least 3.2V if it is the 3.6V half-AA battery type.  A new battery provides 3.67 Volts DC. A bad battery provides under 3.2 Volts DC.  Ideally this should be measured while the battery is under load; added recommendation from Hans777:
    >I have recently found out that an exhausted battery will still indicate >3.6 V with a high internal resistance VM.
    >
    >Checking incircuit: powercord disconnected press PMU reset button for >about 5 sec before measuring.
    >
    >Checking outside: load the battery with a 1500 Ohm resistor when measuring.
    Alternatively, test the battery while it is still in the computer.
    If the battery is more than 5 years old, especially if you totally disconnect the computer from the power regularly, or have left it unplugged for several months at one time, it is likely the battery is dead.
    Sometimes you have to do a more intensive reset of hardware management:

  • Where can I get rid of an old Power Mac G3 Beige?

    Where is the best place to get rid of an old Power Mac G3 Beige? Are there sites out there where Mac enthusiasts would buy it or its part? It has no hard drive. Also have the Multiple Scan 720 Display Monitor.

    Glen.. I'm looking for some 256 sticks of RAM - PC-66 or 100 will do.. and if you want to move that CPU card - is it a Sonnet ZIF?
    I have a Yosemite blue and white G3 that's living here while it's owner gets his living situation sorted out.. it was in rough shape as it sat in a few inches of water and is a bit corroded but not so much it's dead.
    I'm cobbling it into a bit more stable, modern state for him so his 11 year old daughter can use it with her iPod. So far I have an 80GB hard drive and a Lite-on CD burner installed. I don't have much in the way of $$ right now, but can pay postage, if you want to part bits out. I can mail you a G3/266 processor to swap it out if you still want to have a working machine to part with.
    I was going to use the bits from my beige for the Yosemite, but the Quicksilver that landed on my door turned out to be a boat anchor, so I bit the bullet and swapped out a power supply and got the G3 working again as a music server.
    Am still on the hunt for freebie, useable parts..

  • Power Mac 5260/100 Won't Start

    I just noticed recently that my Power Mac 5260/100 won't startup anymore. I just recently replaced the PRAM battery since according to my dad's mulit-meter it was dead. The Power Mac 5260/100 doesn't even get as far as the bonging stage in the startup process. Does this mean I have a dead logic board or bad RAM? I'd be willing to replace the logic board since I have a brand new Apple TV/Video System installed that I payed a lot of money on eBay for (it came unopened when I got it so I know those components didn't fail). I also use it for old games and would like to know if I'll be able to in the future too.

    I wouldn't give up yet. The CUDA reset and PRAM battery are "first responders" when it comes to "mostly dead" Macs, so we always start there.
    When you attempt a start, can you hear anything? Fans? Hard drive?
    Have you tried booting from a CD with a valid system? Utility CDs allow this if they are bootable. My TechTools 3 CD boots into the highest OS the computer will support (up to 9.2.2). It's amusing to see a 6100 or 6200 display the OS9 logo. I had to run utilities every few days on my 6200/75 to keep it limping along.
    Checked everything inside for solid connections?
    I think that one has the "tray type" logic board with scores of connectors along one edge. Those must be clean and seated.
    Some in this series have a plastic bridle arrangement for the rear of the CD-ROM that can flex and lose contact. Check/clean it if present.
    I believe this computer uses "soft power." Have you tried a different keyboard, or tried using the backup power button?
    There were "known hardware issues" with this and similar Mac models. Review that article and this one (includes a logic board diagram). The second link has links to hardware testers if you get it running. The extended warranty period ended in July 2003(?), however.

  • QuickSilver G4 (M8360LL/A) Power Supply W/Dead Fan, Would Like To Discuss

    Hey Everyone,
    I recently discovered my Power Mac QuickSilver G4 (M8360LL/A -- http://support.apple.com/specs/powermac/PowerMac_G4Quicksilver.html) has a dead fan within the power supply. Running an open-case test shows all other fans are working fine. Currently I have a high RPM floor fan blowing A/C air directly into/against the rear of the chassis.
    I've done some research on my options, but would like some help making the best choice:
    (1) Purchase a replacement power supply.
    (2) Install a replacement fan directly into the power supply since it still appears to be functioning normally.
    (3) Purchase a cheaper alternative, but compatible power supply?
    I'll discuss my research into each possibility in order:
    (1) I've found a small number of sites selling replacement power supplies for the QuickSilver G4 systems (shipping not factored into the prices I'm listing):
    (a) $174.00 from DV Warehouse (http://www.dvwarehouse.com/Power-Supply-344-W-PM-G4-Quick-Silver(733-800-867-933-1ghz/Dual)-p-20361.html)
    (b) $179.99 from Mac-Resource (http://www.mac-resource.com/store.php?item=6612513.PART)
    (c) $219.95 from WeLoveMacs (http://www.welovemacs.com/posu344wapog.html)
    (d) At the time I searched, I didn't see anyone selling the same model power supply on eBay.
    If I choose to purchase a replacement, I'll most likely go with the cheapest vendor since it's listing the part as new.
    (2) I'm not confident enough to attempt a fan replacement, and since the power supply fan has been dead for an unknown length of time, I'm not entirely confident it hasn't been damaged from excessive heat. If anyone has a link or useful document that explains how to replace the power supply fan safely, I'd be open to the option. Right now, the most information I currently have is the physical specifications of the original fan (correct me if I'm wrong!):
    Protechnic 80x80x25mm MAGIC (made by Sechang Micro)
    12 Volt, 0.24 Amp
    38.27 CFM, 3000 RPM (max), 29 dBA
    P/N: MGA8012HS
    I would probably want a better alternative if I went this route, since I didn't expect the fan to die quite this soon (although I generally run my system 24/x7).
    (3) I found this other post where another G4 QuickSilver user had the same problem: http://discussions.apple.com/thread.jspa?messageID=2198292
    That thread has a link to the following site with recommendation for purchasing power supplies:
    http://www.Performance-PCs.com/
    However, I've limited experience with voltage requirements and I don't know anything about the physical connector or dimensions of the power supply itself. At best, I know the model of my power supply is 614-0157 and can max out at 344 W.
    If anyone has input and suggestions to help me fully explore my options, I'd really appreciate it. Otherwise I'll land on safe ground by buying an entire replacement of the same model, swap it out, and be done with it.

    I decided to purchase a replacement power supply from DV Warehouse, since it was the cheapest vendor I could find selling the part as new.
    When time permits, I intend to open the original power supply cover to see how challenging it would be to replace the fan. When I do, I'll add more about it to this thread.
    One thing I'm noticing with this power supply fan while it's still in use with my system: If I push on a fan blade with a plastic stick while the system is powered up, I'll see the fan revolve a little (very slowly) before stopping. Not sure if that can be a useful clue as to which component within the power supply could have failed.
    PB PM - About your earlier comment to blowing A/C air against the back of the case being more of a hinderance than helpful, is that true even when the component has no assisted airflow at all? In other words, my logic in using a floor fan to force colder air into the power supply is to help cool the components within it since there is otherwise only natural airflow to help keep the PS from overheating.
    Thanks!

  • 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.
