I've been looking around on a few forums, and I've tried to reset PMU, hold the programmer key, take out battery let it be, external screen,... None of it worked for me. I have tried to install Os X Jaguar without upgrading firmware, so it told me that it needed to upgrade. But I can't do that since it doesn't boot anymore. I tried disconnecting the harddrive and boot it without it, it still turns off. [URl]
View 2 RepliesIt's a G5 20" 2.0ghz machine and is 15 months old approx. He was running something or other, nothing very taxing, when the computer unexpectedly shut down. He restarted it and within a few mins it shutdown again. He restarted it again and used it fine for a couple of hours, shut it down and went to bed. Came to it the next day and nothing. No noise, no lights, nothing. He dropped it off at a local authorised dealer and they thought it was either going to be the power supply (�100 to fix) or the main board (�600 to fix). Sure enough he got the call and it's the logic board thats gone. He doesnt have applecare unfortunately but decided to try his luck and contact apple anyway. Needless to say, they weren't in the least interested and told him he'd either have to foot the bill or toss the machine in the bin. �600 to fix one of these is appauling and more than the machine itself is worth but the options are limited. Has anyone else experienced anything like this and if so are there places to get the machines fixed cheaper? I know this goes to show that it's a good idea to stump up the extra cash initially for applecare but �1200 (the price when new) seems pretty bad for 15 months computing and has really put me off recommending iMacs to anyone else. The days when I can construct my own computer with my own components and run OS X on it, and repair it myself cant come soon enough if this is how it's going.

I want to boot a G5 iMac, connected via ethernet through an AirPort Extreme, (802.11n 100Gb model).
I purchased the last generation iMac G5 when it came out a few years ago and I recently tried to sell it. I sent the item to the buyer and he said it would not start. The Apple logo or for that matter anything would not come up. He brought it to the Geek Squad at Best Buy and they said it was an issue that would most likely cost over $500 in repairs. I just got the computer back in the mail and all that happens when the power button is pressed is the white light on the front lower right hand corner comes on for a second, then the machine shuts down. You can also hear the machine begin to start for about two seconds, then it shuts down. Any ideas as to the problem and whether it is fixable without expensive repair costs?
View 6 Replies View RelatedMy system has randomly shut down twice now in the last two days. Dual G5 2.3. I checked the console log, which I know very little about, and it said this:
localhost kernel[0]: ApplePMU::PMU forced shutdown, cause = -122
Two questions-
what's the -122 code mean?
Do you think resetting the PMU would be the solution to this?
So I have a MBP C2D from early 2007 that up until recently has been running fine. The battery died long ago, so I keep it plugged into the wall which was fine until yesterday. What started happening is my MBP would shut off completely (as if the battery died) and then when I try starting it back up, it would randomly shut off at some point during the boot process (not at one specific point; sometimes it barely makes it into OSX and other times it does not).
Anyone know what could be the problem? I have not installed anything new or changed any settings that could effect the system. To me it feels like the AC Adapter isn't giving the machine enough power, but I don't know for sure.
I have an old macbook 13" (2006) thats running10.6.8 that I use from time to time and it works fine,my problem is that when I shut down or the battery runs flat it will not boot without resetting" pram" etc.and even that is very hit and miss, it wakes from sleep without any problem.

I have put a brand new hard drive in the machine. I took off the plastic bezel to the power cord, to make sure it's plugging in all the way. I turned the computer on while watching the LED's on the logic board. All 3 stayed on, and the 4th never came on.
I have unplugged it, left it unplugged for a few minutes, plugged the cord back in while holding the power, then turned it on (forgot what that was supposed to accomplish). No change.
I have reset the PVRAM (or whatever) 3 times in a row by holding command-option-p-r until I heard 3 chimes after the initial boot. No change.
I can get into open firmware, but have no idea what I could even try in there (other than ejecting the DVD).
I hold down "C" while booting, it chimes, it goes to a blank grey background, then proceeds on to the white screen with the apple. It sits there for a few seconds, then starts spinning the circle for a while, then shuts down. I hear the optical drive spin up, but it does nothing.
My iMac 27 late 2010 does not shut down when shut down in the normal way. I have to shut down with the push button. I have tried disconnecting all the usb connected hardware still no use. Can any body help.I have OS Lion 10.7.3?

I just obtained an Ibook G4, it was my cousins, and it had crashed, so weeks later he gave up and bought a IMac. Anyway, the Ibook will turn on, boot up like normal. I had it turned on for about 10-15 minutes, and it just powers off. I had it plugged in, and it obtained about 11% battery, so I don't think it dies from battery shortage. Something I did notice, the battery charger cord, from wall to brcik is a 250V wire, while the brick it self needs about 100Volts. It isn't the cord that came with the Ibook. Could this cause the Ibook to shut down?

Yesterday I installed Ice Clean and ran a few of the maintenance procedures. This morning when I tried starting my laptop, it started with grey screen and apple symbol, then black screen with white text stating:
Mar 13 08:02:44 launched: can't exec /bin/sh for single user: no such file or directory.
I tried contacting Ice Clean, they claim it is not related. I checked my system profile and I thought I had 1gb of RAM it only says 512gb. Could a RAM failure cause this problem? Have started using target disk mode with my old faithful G4 and everything on the hard disk is still intact. Ran disk utility and all ok!
I have a PowerMac G5 dual 1.8ghz running leopard. It worked flawlessly since the day I bought it.
Then as of last week whenever I booted the computer I would get the gray screen with a black box saying to reboot the computer (in 5 different languages). I would reboot the computer. Same screen.
Is there some way to check what is wrong? Is this typically a hardware issue or an operating system?
I was installing Tiger using FireWire from my Powermac G4 and it was nearly done when my Powerbook (target) died due to lack of battery... When the Powermac was rebooted, I get only a question mark and flashing smile.
I tried to test the C and T keys holding them down during boot up but only get the smiley face every single time... I even disconnected the secondary drive to no avail.
Please could you help me with this problem that i've got with my Powermac G5.

I'm trying to boot from the Mac OS cd (tried 10.4 that it came with and 10.5) and both get to the grey screen with the Apple Logo and that's as far as it gets. No spinning loading wheel.
Tried the following..
PRAM reset
Swapping Ram out
Is there anything else i can do. It's a really good machine so i hope it's not needing a Logic Board repair!
Ibook G4 shut down completely after pulling plug out of outlet. Tried to restart by holding down power button and nothing happens- no sounds, no chime, no light. Removed battery and shows all 4 lights light up. Power cord shows green light when plugged into outlet. Changed outlets etc. Several weeks ago had to get a new cord cause old cord would not keep computer charged even when plugged in. No problems after replacing cord until now. I cannot get it to restart.
View 2 Replies View RelatedI recently came into possession of an iBook G3 (Clamshell) model M6411. Unfortunately, I believe it had a cactus HDD - it shows up in Target Disk Mode on my current model 13" MBP but refuses to format or read - locks Disk Utility/Finder up when accessed. The iBook also has NO CDROM drive in it, either (removed by previous owner, reasons unsure). I'd just like to get it to boot to see that everything else works ok. I have a retail install of OS 9.2.1 as well as an iMac G3 OS X 10.1 install CD, and a 10.3 retail disc too.
I am aware that PPC Macs cannot boot from USB CDROM drives, but they can using FireWire. So, I tried plugging it in via FireWire to my MBP, put the MBP in Target Disk Mode, put the CD in it, and held Option while booting the iBook. The iBook sees the CD on the MBP, I click on it to boot it, and it shows the Happy Mac (this is with the 10.1 CD). However, after about a minute, it shows a strange "broken folder" icon (a Mac OS 9 folder with a tear down the middle) on a grey background. It gets no further. If I use the 9.2.1 CD, it shows a Happy Mac briefly then switches to a floppy disk with a question mark. The 10.3 CD refuses to boot at all. One thing I forgot to mention is if I try and boot the iBook normally, it shows a Finder icon alternating to a ? in a blue Mac OS 9 folder.
G4 won't boot. No startup chime. Power button light goes off right after I power it on. Fans go on and soon switch to high / fast mode.
Tried everything imaginable -- removing all cards, RAM swapping, PMU reset, bought a new 3.6v PMU battery... everything on this forum (I think) except buying a new power supply which I'm trying to avoid.
I've had my iBook for about a year and a half now, haven't had any trouble with it until now. For some reason it won't start up. It's plugged in and the green light is on but it's just not booting up. why my iBook isn't working all of the sudden?

I just turned it on one day & it showed the apple logo as usual, it went to the Starting up screen, and then it just disappears and i'm left with a blue screen, and the mouse sometimes appears for about 10 seconds and then it goes away. i've tried formatting, installing an earlier operating system, using a boot cd, booting from an external hard drive, everything.
View 5 Replies View RelatedMy computer, a Powermac G5, Dual 2.0Ghz, 1st Edition Released Oct 2003, will just freeze. It usually happens within 5 minutes of booting into the operating system. I am also unable to boot from the Leopard or Tiger DVD's to try and install a fresh copy of the OS as they freeze during the install. This is what I have tried so far, but to no avail:
Resetting the RAM and Graphics Card
Resetting the Power Management (PMU)
Resetting the PRAM
Now this is the even stranger thing. I installed a copy of PowerPC Ubuntu Linux 8.04 and it works fine. This makes me think that it is unlikely to be a hardware issue.
Hi I have a problem with my PowerBook
It boots to BSD (Command Line Interface) instead of OS X (GUI Aqua)

Please note that the screen on the PowerBook is broke so I can only use it connected to an external monitor
When I try to reinstall the system, the picture does not get pushed across to the external monitor meaning I can not see what I am doing and thus can not reinstall
I'm having a problem with my Powerbook G4. I kind of screwed up my drivers because I was an idiot and tried to get some Intel drivers to work on the computer through some cheat thing and now my computer won't boot up. I have an install disk but when I try to reinstall it keeps saying that I need Mac OSX Install Disk 2. I never had to use disk 2 before and I never had one to begin with.
View 3 Replies View RelatedI know very very little about computer parts and things like that, but I hope to have provided enough information. When I boot up, both plugged into the power cord, and on battery, the powerbook will reach a white screen with an apple logo in the center. There also is a rotating disk below the apple logo. It will then shortly power down. I made a visit to the genius bar, and they told me something was wrong. I was like DUH!!! They said for $320 it would all be fixed, but I was hoping to be able to find out what was going wrong with it. Sadly I don't have the start-up disk that came with the laptop .
View 24 Replies View RelatedI opened up my G5, to install more RAM, and saw that one of the hard drives was unplugged (I just got it used), and so I connected that, blew some compressed air into it, installed the RAM and closed 'er up. Then I tried to power on and it didn't work (No Chimes, just fans spinning, no video, not even the start up chime). So, I disconnected the hard drive, took out the RAM I put in, and closed it, and it still doesn't boot. Same thing. My keyboard is wireless, but the wireless dongle thing doesn't get any power when it is "powered on". The fans are spinning all the time. (Except when it's powered off, obviously)
View 23 Replies View RelatedHave searched MacRumours and am unable to find a solution to my problem, so here goes: I've recently bought a "faulty" PowerMac G4, which would not boot, however all the parts inside were sold as working.
When I try to boot the G4 the light on the front flashes and the fans begin to spin but there is no characteristic Apple "bong" and nothing appears on the screen.
I know the screen's working because I use the same one with one of my Windows PC's. I've tried pressing the CUDA button and reseating the PRAM battery but to no avail. Does anyone know what my next step should be?
We have a PowerMac G5 machine which won't boot at all. you can hear it turn on and everything (including the chime at bootup) but you won't see anything show up on the display.
Also after several minutes, you will hear a very loud noise come from the machine, the fan you can tell is extremely loud. Not knowing this stuff very well as i'm more a PC tech than Mac, what are some options to troubleshot?
I am trying to do a clean install of OSX 10.5 on my old powerbook G4 15". I am using a 10.5 image file on my external. I partitioned the external using GUID, and restored the image file onto the external. (this method works when installing on intel macs). Unfortunately, I cannot boot 10.5 using this method on my powerbook. Is it because i am using a firewire 800 cable? Should I be booting it using a firewire 400? I know that PPC macs cannot boot using usb, so i am stumped.
View 2 Replies View RelatedHad a quick question. I'm on my third 27" stock 3.06Ghz imac that was replaced yesterday. The good news is that so far it doesn't seem to have any of the problems of my previous two 27" imac's. There is one thing though. A couple of seconds after pressing the power button to bootup there is a brief mechanical sound from the dvd drive like a quick ejecting sound even though there is no cd in the drive. My first 27" imac dvd drive made the sound but the second imac 27" Imac I had didn't. Is this sound normal? Would be curious to know why two out of the three 27" Imac's I had make that noise.
