PowerPC :: G5 Power Mac Startup Problems?
Jul 14, 2008
My Power Mac (2x2GHz G5, Late 2005 model) is acting strange since a couple of days when I want to start it up. When I press the power button the white light comes on for a short time and goes off again. When I press again and hold the button the white and the red light come on, usually also the startup chime sounds, and then the lights go off again. When I repeat the action the computer eventually starts and boots normally and then works normally. Sometimes it works already the second time, sometimes I have to try more times.
Does anybody here know or have an idea what this might be and wether I can repair it myself?

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.

My brother's iBook G4 (I think it's a 2003 model) has a problem with the screen. When the computer is turned on, the screen stays black, although the backlight is on (the apple glows). Sometimes, on start up, the screen works normally for a random amount of time before going fuzzy and then black again.
Any ideas on how to fix this? Is it likely to be a problem with the hardware in the actual computer, or just the screen? Or is it a software thing?

We own a powermac G5 that has had some problems in the past, but nothing like this. When we press the power button there is a chime and fan that shows everything is working up. A white screen appears with the apple sign showing that it is loading. After this screen has been loading for a while the computer just shuts down completely.

I recently developed a problem where my Blue and White G3 Power Mac will not start in OSX. It starts but then displays a screen that tells in four languages to restart my machine. When I restart I just get the same message.This all started when I switched from booting in OS 9 to OSX. Both had worked in the past. Now I cannot return to OS 9. Is there a short cut of keys to press to bring up the start up disk control panel during start up to try switching back to OS 9?

I have an old G5 power mac tower. The hard dives were removed and replaced with PCs ones before I was given it. I do not know if they were formatted. I have the original boot up disc and I want to start again with this tower. The tower turns on but does not recognise the keyboard (which I know works) so I am unable to boot from the CD to have a fresh tower.

We have an older model G5 Dual (no Intel Core) at the office that we tried to install CS3 on. I told them that first we would need to upgrade from 10.3.8 to 10.4.10, which they did, and then installed CS3. But they did it without running the disk utility repair permissions after the OS software installation, as I have routinely done with my Mac Mini at home, after the horror I experienced with the 10.4.9 upgrade. For a couple of days, the computer ran fine, but I noticed an increase in the fan spinning up yesterday afternoon, then quirky keyboard things -- like I'd select an item with point and click, and it would highlight everything else near it, I'd go to quit an application and it would ask if I wanted to quit all applications.
After backing up my current InDesign work files on a flash drive (but not the whole darn art folder), I rebooted and it came up in Safe Boot mode 6 times without holding any key down. Attempts to boot from disk have failed, even with holding down the "C" key. It's also not allowing us to type out full passwords at the log-in screen... you start typing and after you hit four digits, it clears, then only allows two digits. How we can:
1.) Force boot from disk, and,
2.) Hopefully fix with disk utility whatever wonkiness is occurring?

I am running a quad core G5 PPC. I updated to 10.5.1 last week when it was made available and had no problems until yesterday. I tried to empty the trash and immediately had a kernel panic. I restarted and that is when the problem became more apparent then a simple restart! The Kernel Panic continued to repeat itself on the startup screen. I called apple support and went thru all the steps with them including trying to boot from the OS X 10.5 disk, in safe mode, as a target, trying to reset the (I guess I forgot what we were resetting but I was told to hold down Apple-R and Option-P) as well as opening the case and holding down the small button underneath the RAM. Anyway, nothing worked. Even in target disk mode, it made my G4 Powerbook running as the main pop up with a kernel panic! I cant get to the finder to see what the kernel panic parameters are.

My usually stable 10 year old G4 hard drive (attached to VGA monitor) is having serious problems with it's starting up process, so I am presently nursing it along (without shutting down at the end of the day) by using sleep mode. If I shut it down, chances are it fails to power up again. When I press the power on button to startup, I hear the chime and the startup process as usual, then everything stops within seconds, before the monitor screen is due to come on. The two external devices attached are the keyboard with mouse, plus a USB hub. No recent upgrades or changes. Everything is backed up on an external firewire disk. Since this trouble started a few days ago I have replaced the lithum battery and managed to successfully start it up only once (after a number of attempts) so I can nurse it along. I have tried all the usual troublshooting - when I restart in either safe, verbose, or reboot off OSX CD, single user mode, extensions off, or try to reset the PRAM fails to chime twice - in every instance it won't get past the chime. Checking the system profiler 'power on self test' indicates 'failed', failure type is 'external cache'. As I can't reboot off the OSX10 or systemworks CD I can't run Diskwarrior on the operating system or reinstall the operating system. So, I am now at the limit of my capabilities.

My iMac 24 inch freezes on the apple startup screen, then it takes along time for the cog wheel to start turning, and then that's all you'll get untill you switch off. I've fixed permissions and erased and reinstalled but still same issues, any ideas for what to do next?

Last night I was defraging my G4 OS Tiger 10.4.11 and at about 53% the power went out. Now all I get at start up is the Kernel Panic screen. What should be my first step?

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 ?

I am having a problem getting my G5 to boot. Half the time when I turn it on I get no chime. The other half, I get the chime but the boot process does not continue. If I leave the computer on the fans begin to progressively get faster and louder after about 5 minutes. I've tried starting with various USB and Firewire components unplugged and have even gone to just a keyboard and mouse. No change. Can I get the computer to boot from an OSX CD? How do I open the tray? etc.

I have an old "vintage" Macbook with Tiger as my OS. I have all sorts of sleep issues with it, and recently after accidentally hitting the sleep button, I had to force quit the machine by holding down the power button because it was just (beachball) spinning when I tried to start it up again.
I went to start it up and I get the gray screen with the apple on it and the spinning "clock hands" this goes on until I get a darker screen without apple and more spinning. It stays there. We've tried a host of solutions including the resetting through battery removal, we've tried to "archive and reinstall", etc.

I have a G4MDD that has start up issues.
When I push the start up button, nothing happens. If I pull the power plug then reconnect it, the computer will start using the start up button on the front, but I noticed the start up chime is different (like older G4's) and the big fan doesn't start. Also icons in the dock don't bounce. If I then restart using the apple menu, the normal chime comes on, icons react normally, but the big fan still doesn't work.
Just had the big fan replaced so I wondering if I have bigger issues lurking.

I recently reinstalled a clean Tiger on my old MDD G4 with the intent on giving it to a friend of mine in Oregon. Everything was smooth here in Los Angeles. Got the OS on and running sweet... 10.4.11 combo update... all's well.
I drive up to Oregon, set it up in his office using his old CRT monitor and power it on. It chimes and manages to find the Tech Tool eDrive recovery partition, but not the OS on the boot drive. Then, seconds later, screen of death/kernel panic and no boots or startup chimes thereafter.
Steps I've taken:
I have reset the PMU
I have removed all peripherals, including viddy, SATA adapter and all but on stick of RAM
Tried every stick of RAM by itself
No startup chime -- just a fan for a few seconds then a super fan kicks in... no signal to monitor at all.
Strange symptom: at times power was making it to the drives, and other times not. (determined by me putting my hand on the drive to feel its vibration or lack thereof during boot).
Do I need a new PSU? And if so where to buy?

Dual 867 MDD G4
SATA adapter/w 300GB Tiger boot drive and 200GB data drive (w/ Panther still installed)
120GB data drive on IDE 66 bus w/Tech Tool recovery / restore partition

I have an iBook g3 running Tiger that I bought second hand almost two years ago that has been working perfectly up until yesterday. I use it for uni during the day and usually turn the machine off overnight while it charges. The other night I left it 'asleep' while charging instead of off. When I came to use it in the morning it would not wake up and was totally silent although it's pulsing 'on' light in the front part of the casing was on. The charging cable was still connected and was green, indicating a full charge, but the battery-life light display, when pressed, showed only a single light, which flashds a few times, indicating the battery wasn't fully charged.
While trying to get the thing to do something I removed the battery. This caused the ibook to turn off the pulsating light - it was completely off and apparently not drawing power from it's adapter, which was still plugged in. I have been trying since then to get the computer to turn on. No matter how long it is left charging, the battery never indicates anything other than a single light with a few flashes, the computer will not turn on and the cable of the charger stays green when plugged in. I have tried inserting an older battery - which I know worked, it just only used to hold an hour's charge or so - and it will not charge at all. I have also tried resetting the PMU, which appears to have done nothing

I have a dual 2ghz G5 and today when i started it up, it took over 45 minutes to get my home screen. I reset it and it still takes 45 minutes to turn on. A few months ago i replaced both internal hdd's to 500gb and it has 2x1gb of ram. Its running Tiger and i would not like to update to leopard because i need os9 support.What could be causing the slow startup?

My computer crashed today and hasn't been able to boot back up since. It gets to the grey screen with the Apple logo and stops. The fan then ramps itself up to overdrive.
I've started it up in target disk mode and repaired it using Diskwarrior on my macbook. It had to repair quite a bit and then it showed up on the desktop of the laptop. I can read, write and pull from it. I then ejected the powermac and started it up again to find the same problem persisting.

I have an old Titanium Powerbook that wont startup. I haven't used it in about a year.
I've tried keeping it on charge for a day with and without the main battery inserted (which was knackered before I stopped using it anyway).
Any thoughts on what could be wrong with it? An internal battery problem?

I got a powerbook G4 with a smashed LCD. I hooked it up to an external monitor, and 1 thing keeps bothering me - it lags like hell. I have had an iBook g3, now using macbook aluminum, and I have never seen anything like this on a mac before. It lags like hell - it turns on in about 20 minutes. Sometimes it even doesn't. I have tried resetting Pram, Vram, premissions repair, looking @ activity monitor(nothing exceeding 2-3%). HDD capacity - about 55% full. I cant even describe whats up with it - launching any app takes about 2-3 minutes. For instance, iTunes launching takes 3,5 minutes and none of the songs are playable. I have tried to create a new account - did not help.
So lets start with system preferences. I have :
1,5ghz PowerPC processor
256mb Ram
Tiger 10.4.11
HDD 80gb Fujitsu MHT2080AT
So at first I though it was the lack of RAM - I bought a 1Gb stick. Now I am thinking it is because of the HDD. But I am not ready to buy another component randomly.
