PowerPC :: Cube Will Not Power On
Oct 31, 2006
I just bought a used cube from a local computer shop. It was abandoned by its owner. I saw the computer running last week when it was in the shop. I went to pick it up today and got it home. I can't get it to power on. The power "button" pulses when I push it but nothing happens. The ACD display that it came with gets power. I have tried reseating ram, reseating the DC to DC board and the graphics card riser.

I know I can get the bulk of it here: [URL:..] But is there a controller board? I can't find any documentation on this thing. I want to use it for a PC. Making an acrylic top is no problem. Just looking for pin-outs, dimensions, and maybe some pictures of someone else dissecting one.

I have two macs(one is macbook, another one is G4 cube). On my G4 Cube OS 9.2 is running and it is up to date. (last firmware update installed) I want to install mac os x tiger on it but i can not. I tried almost everything but i couldn't install yet.
Firstly I downloaded tiger.dmg and burned into a dvd, then inserted to the Cube. It can read the DVD but couldn't run the tiger dmg file. so i could not install in this way.
Then i connect the macbook to my Cube via firewire and I inserted the installation dvd to the macbook but the result was same. cube can read the DVD but couldn't run the tiger dmg file.
Then I changed the host and target. I saw G4's harddisk as an external harddisk on my macbook's screen and i found the OSInstall.mpkg after I mounted Tiger dmg file on desktop. I choosed as installation destination G4's harddisk and installed the tiger on it. Then i open the Cube and I opened startup disc on os9 to choose os x as startup system. Though Tiger's system files are on the G4's harddisk there is no choise as os x in the startup disc menu so i couldn't start tiger.
What can i do for install the tiger on my Cube?

I recently acquired a G4 cube with no os. It came with the original disks, but the only problem is instead of booting from them a flashing question mark on a floppy drive is shown. I have tried resetting the PRAM and NVRAM which hasn't worked.

I just recieved the G4 Cube from Flyinace2000, MR member of vast integrity and great packing skills.
I want to try to put a new hard drive in it before I boot it up to see if that will help things.
Where would I find a photo guide for Cubes and switching the HD?

I just picked up my second G4 Cube. This one falls out of the enclosure when sitting upright, though, not a good thing.

My grand dad found some old g4 cube speakers. You know the round ballish ones. They used to connect to a cube with usb. You could just plug it in and they would work. My granddad now has a imac g5. He wants to connect his cube speakers to his IMac.

I currently have a 450MHz Cube with a standard CD-ROM. I would like to add a CD burner, but I'm debating whether to buy an internal burner, perhaps one that originally came with the Cube, or a faster external version.

Just got a cube and a 17" ADC studio monitor off ebay from different sellers and there is a problem with one of them... when i connect everything and I switch everything on the cube turns on and automatically switches the monitor on but I get no picture. I get the tune that the thing started up but no picture at all
i tried the cube with a very old compaq monitor i had running around that uses vga and still no picture...
I guess it is the cube that is the bad thing... Am I guessing right?
what can I do to solve the problem (apart from getting another cube)

I'm looking to replace my current failing speakers and I'm thinking of getting the old Apple Pro Speakers (with that fancy connector) or the USB ones that came with the G4 Cube. Griffin had their PowerWave thing a while ago that could amplify the USB speakers because the USB port didn't have enough juice to power the speakers like it did on the Cube. My question is, does anyone know of an alternative USB amplifier that could get the job done? Or a way to convert the Apple Pro Speakers into a usable form? I have the unibody MacBook, is this even an issue anymore, or are the USB ports the same power as the Cube's?

My girlfriend has a 12 inch Powerbook G4. She noticed that the battery life was starting to dwindle. Tonight, she tried using it. It wouldn't power up. The battery indicator showed one flickering power circle. The adaptor has the green circle on it, indicating the battery has a full charge. However, the computer won't charge up.I've read the 12 inchers don't have separate PMUs. Could that prevent the machine from starting? She was using it earlier this evening, as she e-mailed me pictures from our vacation.

I have a iBook G4 laptop and there seems to be something very wrong with it. It started a few days ago just randomly. I was reading something on the internet and the screen went black on me, but the power was still on (I clicked CAPS LOCK to see if there was power). I then proceeded to push the power button and the power went off. When I pressed the power button again to turn it on, it made that internal noise it always makes and then the fan came on, and wouldn't turn off. There was no picture on the screen at all. Completely dead. But there was power, because when I clicked on the CAPS LOCK, the light came on). I tried pressing on the power button for at least 15 seconds and even went as long as a minute, and the power didn't go off.

I'm using a B&W Power Mac G3 with 512MB RAM and OS X Tiger for a SMB file server (with 5 users) and a USB printer server. Everything is working good, but I have a problem.
It doesn't have a monitor or keyboard/mouse attached normally (I can configure it via VNC). The problem is that I would like to be able to turn the machine off when it's not needed (like at night sometimes, days when I won't be home, etc.). I would like to just hit the power button and have it turn off, however it puts it to sleep instead.
Normally, sleep would be fine, except on the B&W, the fans still run, just the HDs shut off, so it's still noisy as heck.
Is there a way to make the power button shut it off? If not, any other easy methods of shutting it off you can think of? Via VNC won't cut it, as my dad needs to be able to turn it on (not a problem) or off as well.

I have a PowerMac G5 with the first motherboard that is out of order, and another PowerMac
G5 Late 2005
with 2x2.0GHZ
Mounting the powersupply from the 2004 on the 2005 is the powersuply compatible or not?
EDIT: I looked on Mactracker and compared the two:
Max Watts in the first is 604W and 450W on the late 2005.
I want to put a powersuply from a G5 2004 (604W ) on a G5 2005 that had a 450W powersuply is this possible ?

While poking around on youtube I found Steve Jobs presenting the Cube in 2000. Seems like it was the mid level headless Mac people call for on the Internet. I wonder is there any interest macrumors? I like the Cube design and the way you were able to access the guts was very cool. Some have written that the Mini IS the natural progression of the Cube but I think the Mini is too locked down. It would be nice to make drive swapping a little more user friendly and maybe have a PCI slot (or two) available. Maybe even the ability to upgrade CPU/GPU. Think of it as a Mac for people who can't leave well enough alone but can't afford a Pro.

Finally got around to reinstall Ubuntu 9.10 x64 natively on my MBP, since I accidentally deleted the partition that was already on there. Anyway, got it all perfectly working, then I played around with the 3D cube. I was freaking blown away how neat it was! Does anyone know of something like it for Mac OS X? I searched, but couldn't find anything.

My G4 Powerbook 17" 1.5mhz stays on most of the time. Only thing that really gets any rest is the screen once in a while. For this reason, is it better to just power it off the powersupply and take out the battery? Any harm done in having the battery there and charging for extended periods?

I am getting ready to install a second (500 GB) hard drive in my Power Mac G5, and I was wondering how it will show up. I want to install OS X and all of my Apps on my 250 GB HD, that is already in the computer, and put all media and documents on the 500 GB. Will the additional HD mount on the desktop, light an external HD does?
How would I go about doing this?

During last 6 months I saw at least 5 PowerMac G5 that shows the same malfunction symptom, hangups, no video, fans running at full speed. It seems to be the main board, and many of them are 2.0 dual version (different models) and today I have a 2.3 Dual processor with the same problem. Anyone has other experience like me?

My mother just had her G4 Mac die on her. She bought it four years ago! She got the last MDD Power Mac G4 with dual 1.42 GHz PowerPC 7455 processors, running on OS 9!
Photoshop, Illustrator, Quark, Flash, Office, GoLive, InDesign, Image ready, Dreamweaver and so on, is the programs she use the most.
She has been quite satisfied thus far with the performance of the G4, until now(DEAD...)
She now considers getting an Mac Mini, with 2,0 Core 2 Duo Processor, 2 GB Ram running on Lepoard with a 160 GB Harddrive.
My question is - Is the Mac Mini powerful enough for the programs that she uses mostly(mentioned above)
Will the Mac Mini be more powerful or equal to the G4?
The Mini has a integrated Intel 950 GPU - Would it be enough to run does programs decently?
I know that the buyers guide suggests not purchasing a mini, but we are short on money, and she needs the computer to do her job as a web designer/art director!
An alternative would be to purchase a refurbed G4 similiar to the one she had before!
I dont know what to advice to her. When money is an factor, and considering that she has been happy with the G4 for the past for years, I just dont know...

Currently it is almost entirely unresponsive. I came to wake it from sleep a few days ago and it refused to wake. It is totally unresponsive to the power button on the Apple Cinema display and when the power button on the front of the tower is used the button lights up blue and then goes out. There is no fan activity or other sign of life. There is no burned oder or evidence of anything charred.It is a dual 1.42 MDD FW800 machine with AGP graphics. Model: M8570So far I have:
-Removed and reseated the graphics card, RAM and other PCI cards.
-Removed battery and let it sit unplugged over night.
-Performed PMU reset. (once)
At this point I have come to believe the power supply needs to be replaced. it is model: 614-0224 (360w). After looking online they are stupidly expensive, from $180 to over $500 each. I will be ordering a new MB (PRAM?) battery (Saft 3.6v LS14250C) and replacing that as well.
Questions:
- Have I missed anything here? Is there any other explanation or method of troubleshooting I should try?
- Is there any cheaper source for the power supplies? Why are they so absurdly expensive? Does anyone here want to give me a sweetheart deal on one?
- Can anyone recommend a source for the LS14250C battery locally in Manhattan? Radioshack has it as an online only item and wants $15 for it.

Yesterday it would not power on, the day before it was working perfectly. I tried switching out the power cord, and also holding down the power on button for a few minutes. Purchased in August 2005 never had a problem. It is 1.8 GHz 20-in integrated flat panel.
