Power Mac G5 :: Blank CDs Not Mounting -trying To Reset PRAM
Nov 30, 2007I have tried two different brands of blank CDR in my drive and both times, they fail to mount and in Disk Utility, show up as Sony DVDs (neither of them is a Sony or a DVD), but not writable. I have no problem with media that already has content. I've tried resetting PRAM, but nothing else yet.

Power Mac :: Unable To Reset Admin Password
Apr 21, 2012On my old iMac with OS X 10.4.11 I forgot my admin password. I have the installation DVD, but it doesn't work like the Mac Support instructions seem to indicate. When I install the Mac OSX 10.4 DVD and choose utilities to change password, the only change password option is for the DVD itself...no icon for the associated iMac hard drive. I believe I'd be changing/using a root password rather than the Account Admin Password that I need to change. How can I get out of this situation and identify a replacement for the forgotten admin password on my Admin Account?

OS X Yosemite :: Power Reset Required After Sleep
Dec 9, 2014Often when I put my iMac to sleep in the evening I find the system unresponsive when I come to use it the next day. I can see instantly that the system has an issue because I see that the screen backlight is on. The system does not react to any mouse or keyboard input and requires a power off reset to restart.
I thought that the issue may involve Parallels which is often running when I have this issue , however, I have spoken with Parallels support who recommended removing parallels, repairing the disk permissions and reinstalling Parallels which appears to have had no effect.
The iMac is very new and was purchased in November 2014 and is configured with a 3.5GHz i7 processor, 16GB or RAM 3TB HD and NVIDEA 980 graphics card.

IMac :: Can I Reset Power Saver Settings In A System
Jul 28, 2009I have this iMac for slightly over two years and when I forst got it I thought it would be a good idea to have it start up a 6:55am each weeday. After about a week I changed my mind and went back into Power Saver and turned off the settings. Since then, I can't tget the machine to quit auto-starting at 6:55, 7:55 and even sometime 8:55. I have called Apple, taken it in to an Apple store, they even claim to have replaced the computer

Dec 11, 2007I installed Leopard about 3 weeks ago and have been very pleased with it; however, since then every so often and when booting up my G5, it shuts off again. I boot again and a small window appears asking me to reset the date and time. Each time this happens I am able to reset the time and date correctly in System Preferences. The computer is about 3 years old so it may be the internal battery and nothing to do with Leopard. Or, could it be a bug in Leopard?

Power Mac G5 :: Loud Wild Fans - Hang Ups And Hard Reset
Dec 7, 2007I have a DP 2.7 G5 Tower and lately I come into my office to find it with dark screens (dual monitor setup), and I am unable to in any way control it by the mouse or keyboard. I imagine it's "hung?" The fans are on full blast and it sounds like it's planning to take off at any moment. I've awakened in the middle of the night by the sound of it and it's in that same state. What to do? I restart it at the power button. I then have to run Disk Utility to verify all the disks and RAID setups.
Anyway, I read about the coolant leaks issues. I started running a temperature monitoring program for the past few months, and its been doing about the same type of pattern since I started monitoring it. Doesn't appear to be unusual. Everything appears to be working fairly well, except for this issue. System is OS X.4.11, and checks out fine with Disk Utility. So far the hard reboots haven't done any damage to my disks, but it worries me greatly. Also the "liquid cooled" aspect worries me greatly.

PowerPC :: Powerbook G4 Won't Power Up - Battery Indicator Showed One Flickering Power Circle?
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.

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.

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.
