My G4 MDD Dual 1.25 wont do ANYTHING AT ALL

It was behaving normally and I powered it down last night before I went to sleep. When I woke up this morning expecting to be productive I tried turning on the computer and NOTHING happened at all. No fans, no hard drives, no nothing. I tried turning it on using the power button on the system and the button lights up for a second and goes right back out. Can anyone suggest what may be wrong? Is it the power supply? Wouldn't I have had warning signs? Any help would be greatly appreciated, I am a freelance designer that works from home and my computer is my livelihood.

Fix for a Mac that won't power up
Mirrored Doors G4. When you pressed the power button, the button would light up, but the computer would not turn on. The fans on the power supply wouldn't turn on.
FIX: unplug the machine, pull the clock battery, hit the power button to discharge. Then plug it in without the clock battery. The machine should boot perfectly. Shut down, reinstall the clock battery, and now the system is fully functional. Macosxhints
Even if off there could be a power "event" that knocked your Mac out. Get a UPS. An APC RS1500 should be able to handle what you have easily and offers a battery pack add-on for a couple more hours run time.
After the above fix, if that doesn't work, boot into Open Firmware and type
reset-nvram
set-defaults
reset-all
Then do a Safe Boot or boot into Single User Mode and run "/sbin/fsck -fy"
Or, you could option boot or "C" boot to Tiger DVD, but your best bet is to OPTION boot probably to a clone of your system, or an emergency system disk just for repairs and emergencies (or eDisk if you use TechTool Pro 4).
I think the above hint from Macosxhints will do the trick (hopefully!).

  • PLEASE HELP!! ipod wont do anything at all

    Well, my computer crashed some time ago with my itunes, but I was successfully able to restore them. However, about an hour after my ipod finished updating, it froze. It wouldnt do anything, and as it was frozen while playing, it ran out of batteries a few hours later. I wasn't too worried, this happens to me alot, I just recharge the Ipod and it works. But after charging the ipod for about four hours, it was even worse. Although the screen was not frozen, all it would display is an apple and then a folder with an exclamation point. I found out that that means i need to update my Ipod. So I downloaded the Ipod Updating software and plugged my iPod in. But the program just read "Error" and kept disconnecting my iPod without stopping it. Now my ipod is still completely useless, only showing that folder, and making really loud buzzing and clicking noises. Does anyone have any suggestions?!?!?

    Haley,
    You didn't say if you use a Mac or a PC. If you use a Mac fire up Disk Utilities and do a Disk Repair. if that doesn't do it then do an erase and reload the iPod software into the iPod.
    If you're on a PC I haven't got a clue.

    MY Ipad has become locked and is giving an error message . 'This Ipad hasnt been backed up in 2 weeks. Backups happen when this Ipad is plugged in, locked and connected to WiFi''  How can I connect it to WiFi when I cannot even unlock it?

    Press and hold the power and home buttons until the device shuts down. After a short while the apple will appear and the device will boot up.  Things should work then.

  • Recommendations? USB 2.0 & Firewire PCI card for MDD Dual Boot G4 (1.25 Ghz

    Can anyone recommend a good USB 2.0 and Firewire combo PCI card? (at least 3 USB 2.0 ports and 2 FW) for my G4 MDD Dual Boot- 1.25 Ghz)?
    I have an Orangelink+ Micro USB 2.0/FW PCI card from the days of OS 9- that's supposed to be USB 2.0 under OS X, but isn't (it shows up as max 12/mbps in System Profiler). I'd like to get an external Hard Drive and most of them are USB 2.0 now.
    Another question:
    Under system profiler, it shows that I have one USB 2.0 port. I'm assuming it's an internal port, because all of the external ports show transfer rates of 12mbps. Is this a correct assumption?
    Thanks in advance for any help!

  • ATI X800 XT 512MB  on MDD dual boot dual 1.25Ghz.... possible?

    Hi,
    Just looking to see if I can install a Mac version of the ATI X800 XT 512MB on G4 MDD dual boot dual 1.25Ghz machine?
    If so... great... I'll go pick it up straight away.
    thanks
    PS. I know it won't accelerate 9.2.2, but I already have the 9200 PCI card to accomodate that.

    Just following up on japamac's excellent response.
    ADC presents a seriously limitation on cards since the only two retail cards (no flashing, no fuss) on the market are the ATI 9600 and 9800, both without ADC.
    I use a modified 9600 Pro from a G5, which has an unpowered ADC. Unpowered because the the ADC tab doesn't align, although some people have modified the card further to get power to the ADC port. For info on both of those mods, see:
    http://www.pistolerapost2.com/viewing/96002g4.html
    There is one last card -- extremely -- I can think of with ADC and more oomph than the retail 9600: the Apple OEM 9700. That was a BTO option for the MDD. Here's some info on that card:
    http://www.xlr8yourmac.com/Graphics/Radeon9700PROOEM/index.html
    Again it's really rare because it wasn't available even as a BTO option for very long. They fetch a premium on the used market when you find them.
    What ADC monitor do you have? I hope an LCD. In which case, something to consider is the Apple ADC-DVI adapter which will set you back $100. It's basically a kind of splitter, with a brink supplying power to ADC monitor while passing the signal from the DVI port. Yeah this adds to your costs, but gives you more options in terms of cards.
    Oh more thing about 9.x acceleration which you mentioned. With ATI cards, you might need to pull an extension or library from the Extensions folder to keep 9.x from stalling at boot. I had to do that with my 9600. Sorry, I'm on my MBP now, so I can't tell you which ones. Let me know if you need/want to know which ones I pulled.

  • PowerMac G4 MDD Dual 1.42 not recognizing hard drives

    I have a PowerMac G4 MDD Dual 1.42 GHz, and I just moved across country, and it was working before the move, now it won't start up. It goes right to a grey screen with a blinking question mark and finder icon. I have 2 hard drives in it. One with Leopard, and the other with Tiger, and it won't recognize either. I reset the PRAM, I checked all the connections inside, started it up holding the option key and it doesn't show either hard drive. I also started it up with the Leopard install disc and using Disk Utility it still couldn't find the drives! Next thing I am going to try is resetting the PMU and see if that works...otherwise both hard drives went bad or possibly the cable for both of them went bad??

    ... I checked all the connections inside...
    When you checked the cable connections, did you check both ends of all cables? For example, if the moving loosened the ATA cable at the logicboard/controller end, checking the drives' connectors won't reveal much.
    Do the drives spin up when you power the machine on (you may need to open the side panel and gently touch the drives while booting to test this)? If not, suspect a power cable connection issue. If they do, suspect an ATA cable connection issue.
    Best way to confirm a cable connection is sound is to undo it and redo it - they can look okay when they are not okay. Do this with the machine shut down, of course.

  • Convert from a 15 pin to work on a G4 MDD Dual Processor

    I just purchased a Powermac G4 MDD Dual Processor. I have an Acer AL1916WAB monitor. The monitor is a 15 pin. What do I need to purchase to connect it to the G4? I haven't a clue.
    All help is appreciated.

    I found my answer with a little research and I'm set! So I don't need help after all lol!

  • Best Video Card for my MDD Dual 1.25 and Video Editing?

    I know that this has been discussed several times before. I just never saw any real answers. I was planning to a little more intensive video editing so I got the Motion 2.1 Trial. Well, doens't allow me to install saying that my video card doesn't meet the specs. I'm confused, I read the requirements and read me files and my ATI Radeon 9800 Pro seems to meet the basic requirements. However, the About this Mac says that it doens't support Core Image.
    I guess my question is what would be my best and least expensive video card upgrade? Or is mine set up incorrectly or something? I've read elsewhere that this card should work. I'm just a little confused why it doesn't support Core Image....I may go all the way to Final Cut...Will this card work with that application?
    Any info would be great.
    Thanks.
    Robert

    Thanks and sorry for the confusion...I just realized
    that mine is only a 64mb card. It's the stock that
    came originally in the MDD dual 1.25 I believe. I
    had no idea that the same model card can have
    different amounts of memory. It still says that it's
    the ATI Radeon 9800 Pro...just 64mb and no core image
    support
    It sounds like you may be mistaken and have an Apple OEM ATI RADEON 9000 Pro. That had 64MB, was stock with the MDD, and does not support core image.
    There was also an Apple OEM ATI RADEON 9700 Pro with 128MB available as a BTO option with the MDD Dual 1.42GHz. Sometimes they pop up on eBay, although they are sought-after because they support core image and have both an ACD and DVI connection allowing for two digitally-connected LCD flat-panel monitors.
    To my knowledge there have only been 128MB and 256MB versions of the ATI RADEON 9800 Pro Mac Edition.

  • Powermac G4 MDD Dual 867 vs Powermac G4 Single 1.0 FW800

    Hello, I have been a mac user since 2004. I had an iMac G5 1.8 that crashed and I want a replacement for the next year until I can save for a Mac Pro. I saw a great deal for the above Powermac G4's: MDD Dual 867 for $200 and Single 1.0 FW800 for $150. My friend was going to give me his 23" Apple Cinema HD ADC. I will be doing email, internet, about 90% of the time, and sometimes use Photoshop and Lightroom the rest of the time. I will max out the RAM at 2.0Gb, upgrade the Video to 9700 or 9800, and install 10.5 Leopard. What do you guys think?

    C24, welcome to Apple Discussions.
    A great price for both. Several considerations. Here's a link to the specs on both. http://www.everymac.com/systems/apple/powermac_g4/index-powermac-g4.html
    1. Are you currently using OS 9 in classic mode. If so, you can use either Mac in Tiger. (same as your G5).
    2. Do you want to be able to boot into OS 9. Only the MDD will do this.
    3. The MDD Dual might be slightly faster if you use multiple applications at the same time and if you do extensive graphics/audio.
    Unless you want to boot into OS 9, I would choose the 1GHz. Note: If you upgrade to Leopard, you won't be able to use classic mode.
     Cheers, Tom
