It hung tonight while trying to burn a CD using Toast 9, which I could not even Force Quit. I closed it down using the Power button but when I rebooted it wont play, burn or recognise any media in the CD/DVD Drive! I have had the original replaced a year ago.

Mar 19, 2008My 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.

Feb 10, 2008I 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.

Apr 18, 2008I had a bad power surge (USB hub that was plugged into the back of the display had the wrong power cord plugged in... very stupid mistake I know!!) take out my 23" Cinema Display. The display shows no sign of life (no power light, etc) and the brick has been tested and is OK. My local service place says that they will have to send the display back to Apple which means a minimum of $400 for repair so I'm wondering if anyone has had a similar issue that they resolved successfully? The service place suggested that Apple would replace the logic board but is there any way to test to see if this is the main issue? I have seen logic boards sold separately online but would be hesitant to buy it without know that this would fix this issue.

Nov 8, 2007I made this a new topic because I think it is important enough to do so. Probably most of those that originally complained about this have moved on to the new MacPro but I am sure there are still enough G5 owners out there that still have concerns about this topic.

Its amazing, my G5 is like a new machine; no more of the annoying power supply beep; although, I learned to live with it after a while and didn't even notice it. However, the silence is now very noticeable.

View 5 Replies View RelatedPower Mac :: What Steps Need To Take To Isolate A Graphics Card Failure In A Power Mac G5
May 29, 2012a friend recently gave me a g5 power mac that had some issues, and the failure was described as intermittant. The machine supposedly would work properly when booted and start freezing up after time, but if turned on the next day it would work properly for some time. I assumed it was an overheating issue, but apperently there is more to the picture. I have tried booting the machine quite a few times and the display always reads no signal. The machine sounds as if it were booting normally, but there is not output. At first I assumed it was my display cable, which was a DVI-D single link, however the DVI-D dual link cable leads to the same result. Is it nessicary to have a DVI-I cable? None of the error LEDs light up on the motherboard. After doing some hunting I haven't found anyone with the same issue, but I am wondering if I should assume the graphics card is dead. What steps do I need to take to isolate a graphics card failure in a power mac g5?

Power Mac G5 :: Frequent Required Power Cycling Of Dsl Modem?
Nov 18, 2007I have the problem that I need to frequently power cycle (shut off and on) my dsl modem to maintain a reasonable speed with my internet connection. It is making the internet experience pretty user unfriendly. Does any one know whether there is a way to optimize my internet connection such that this is not required so frequently (couple times a day)? I am on my second dsl modem, and the same problem has occurred with each of them. ATT simply advises me that my solution is to power cycle the modem to sync the system, whatever that means.

Power Mac G5 :: Won't Boot Up Blinking Power Button After Adding Ram
Dec 6, 2007I added 2 sticks of 512 to my power mac g5 1.6. I had ahard time getting the computer to see the new ram, but finally was able to kinda get it working after zapping the pram. However my computer only saw these 2 sticks as 256, odd. So i attempted to troubleshoot the problem. I tried just installing the new ram, but the computer wouldnt boot. I tried a few different combos with the other 4 sticks i had, but nothing. I put the old memory back in, and still nothing. The power led looks to blink once every five seconds or so. I tried pressing the pmu reset button, but still the same out come. I also tried taking out the battery, nothing.

Power Mac G5 :: Dual 1.8 Not Booting When Pressing The Power Button
Dec 13, 2007I 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.

PowerPC :: Making Power Button Shut Power Mac Off?
Oct 7, 2006I'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.

Mar 26, 2012I still have the same G4 Digital Audio which came used but with a clean OS, which I managed to up grade to reach the 10.4.11. Its works great and I love it. I can only imagine using a real Mac Pro 2012. The software is legacy and It will not support the QuarkExpress9 for example. So what if I found and upgraded to the 10.5.8 or the max OS my G4 can handle? Is it worth it?
