Power Mac :: Dual G4 Turning On?
Jun 26, 2012
I'm working on a Mac Dual g4 desktop computer at work, and it won't turn on. We've always had troubles with a sticky button, but it usually comes on after a couple tries. Just before I had this problem, we had tried to switch to an older startup, which gave us trouble, so we went to restart the computer and that didn't work either. Have been reading through discussion posts etc to troubleshoot, tried switching out the power cord and PMU restart, no luck. Unfortunately don't have a keyboard with a power button... What now?

I've bought a dual 2Ghz powermac G5 secondhand, and bought a new drive and installed 10.4.3 and updated to 10.4.11, the fans where always on full blast so i searched the forums and ran the Thermal Calibration utility, everything seemed fine for a week. Then it started turning itself off with a click from the power supply after i left it on all night while downloading.

i have 2 LCD's hooked to the new Mini as such:
1 going mini display port to DVI adapter to DVI on 19" Monitor (standard monitor)
1 going mini DVI to DVI adapter to a DVI to HDMI on 52" LCD (Samsung TV)
i just sold me iMac and switched to the Mini not only to be able to hide the Mini which i couldn't do with the iMac but also when i watch a movie full screen on the 52 i was never able to turn off the iMac monitor and would have to cover it with a towel so that it was dark in the room except for the 52 showing the movie.
my thought was that with 2 monitors separately hooked up to the Mini that i could solve the turning off the second monitor problem as they would now both have power buttons. besides making it dark in the room i also like to have the monitor off and so that i can have Plex on the 52 always in full screen mode so my wife can just hit "Watch Plex" on the logitech remote and the TV and Stereo switch to the proper inputs and away she goes to watch whatever without having to touch the computer which when both monitors are on works perfectly.

I have a Powermac Dual G5 @2.0ghz, with 8gbs of ram, and 2 1tb drives running the latest version of 10.5. The problem I have is that I have 4 LCD monitors that I was using with my PC. I swapped that out with my mac, and while I am no novice, I didnt take into account that I cant just put any AGP and PCI video card into the system. What I need to know is if I can use two PCI video cards both with Dual Monitor outputs, and if so, which cards should I buy, and where? I found some video cards on ebay that are PCI, and it is quartz extreme compatible, but I am unable to use it with the AGP card already installed. The person selling the cards was unable to answer whether or not two of those cards could be used together. I only have about 75 per card to spend. Please help, I cant go on using this awesome machine with only one 19inch LCD. and I cant afford to buy new monitors

I had a weird issue this morning. I started computer and it did not make the chime sound, it didn't do anything at all. I disconnected it from the extension cord as well as all the peripherals attached to it and nothing. I tried a different start up disk and again there wasn't a sound. Then i unplugged it and reset the SMU on the mother board and air sprayed the computer to remove all dust. Then plugged it back and it came back on.

Why is my ADC monitor not turning on after I put my G5 to sleep? I am running an adaptor to my G5 from the ADC monitor (DVI to ADC).The screen usually runs fine when I reset the monitor or turn it off but as for when I put it to sleep, no such luck..This has happened once before and last time I just waited and randomly turned it on a couple days later and boom, the screen booted up.I have tried basic options, like resetting the computer several times, pulling the power cable out of the G5 for several minutes and even a PRAM reset but nothing seems to have made it work as of yet.I assume it's within the G5 as it has happened a few times and the monitor works fine when I test it on other computers..Also as I mentioned before this is not the first time it occured and it just randomly seems to come on whenever.

I scanned the posts and didn't see this question, but honestly I didn't read all 20K + messages.I bought in late 2005 a dual 2.3 G5, about 6 months before the Mac/Windows combination came out. Does anyone know if I can upgrade or is it too costly to do so compared to buying a new machine.

As the title asks, really. Is it safer for an iMac to be shut down from a power cut whilst turned on, or whilst sleeping? We tend to get a power cut once every couple of months.

I currently have 4 x 512 PC3200 installed. Is it possible to remove 2 of the modules and replace them with 2 1gig PC5300? I remember my old G4 used pc100 and I was able to upgrade with PC133. Not sure if the same concept applies here.

I am posting this here as well as in the Logic area, to try to get some help. I am desperate, as i can't work. In Logic Pro 7, I can't click anything in the right pane of the bounce dialog box. I CAN select PCM, Mp3 etc. on the left, but get no response from the mouse when trying to change the sample rate, interleave, dithering etc. on the right. I also can't click the flip-box to select different packages in the Loop Browser. I haven't noticed this happening in other applications. DOES ANYONE READING THIS KNOW HOW I CAN GET SOME HELP FROM APPLE? I am told i can't even buy apple care because my computer is too old. I don't know what to do. Tried trashing prefs. Not running any failed audio units. Nothing new in software update. Don't really know what else to do.

I cannot seem to get my second hard disk (lower drive bay, B) out of the machine.
I've disconnected the data and power cables from the drive, lifted the B drive swing tab out of the way...but no matter what that drive seems to be wedged in there pretty good.

I have a question about the Dual-Proc MacPro's power management:
If you are only running one or two applications, using one or two cores, is the power management smart enough to put one of the processors to sleep, or into a low-power mode?

Is there an upgrade beyond 10.4.11 to Leopard 10.5 that doesn't require an intel-based mac. I bought Snow Leopard 10.6.3 and it tells me that I need an intel based mac. Will 10.5 leopard work?

I have a G5 Power PC with Dual Ghz 2.5 processors. I have two 250 GB hard drives, my primary drive has 45 GB available and my secondary (storage drive) has 10 GB left.
My problem is that I have 6.5 GB of installed and recognized RAM, and yet I constantly hear my hard drive spinning up, as though the OS is using virtual RAM off of my hard drive(s), and ignoring my plentiful system RAM.
This happens when launching every application - big or small - and even surfing the internet. I open Activity Monitor and see that my Virtual memory is 7.2 when idle and grows to 8.5 with a couple of programs open. My page in/out is 48919/0.
This "spin up" sound happens all of the time, whether I am working on something or not, but particularly when I launch programs. No background programs (such as a virus scanner) are installed or running.
So my question is this: Is there any way that I can adjust OS X (latest version) so that it strictly reads my system RAM first before going to my drive? Some setting somewhere? I thought that OS X (as in all computers) only went to the hard drive's VM when it ran out of System RAM. Am I missing something?

I am about to sell my Dual 1.8Ghz G5 Power Mac. I bought this from somebody used, and it came with Leopard on it.How can I erase everything on it? I am used to a dell where I just pressed two buttons and it just put a clean copy of XP on. Do Macs require discsI wasn't given a disc when I purchased the Mac, so I sure hope not!

I am thinking of buying a PCI Express Power Mac G5 to run PPC apps.
It seems I should not buy a quad because of leaking.
Are the dual core reliable?

I have Dual 1.8 GHZ Power PC G5 with 1.5 GB DDR SDRAM, with OSX version 10.4.11.My computer has been getting increasingly crazy over the past couples weeks. I'm even having trouble typing this because the screen occasionally "flashes" or "jumps" when I'm in the middle of a task.I noticed the problem first when I would make a new folder. After an untitled folder was made, when I would try to give the folder a new name, the screen "jumped" and I would have to try several times before I could complete the task.
