G4 Power Mac (MDD) - has trouble booting after shutdown
I have a Power Mac G4 MDD (1.25Ghz) that is having issues when it is shut down. The power button on the front of the machine does not start the computer every time. Sometimes it works, sometimes I need to wait a while before it will work. When the button is pressed, it does not light up or anything.
I have noticed that if I sleep the computer it always seems to wakeup when the front button is pressed. But if I shut down the G4, is does not always bootup.
I have also performed multiple restarts when performing software updates, and they always seemed to work fine.
I have changed the Saft battery inside - it was at about .4v
I have performed a CUDA/PMU reset using the button on the motherboard, and followed the Apple procedure. (disconnect power, and accesories, press reset button, wait 10 seconds, reconnect, restart) It did not restart right away, had to wait 20 minutes or so.
The G4 has a new installation of Tiger, with all of the updates.
I have identified that the PSU is dropping the standby voltage on Pin 1. It does not do it consistently, but when the 25v is missing from Pin 1, the G4 does not start. After a couple of minutes, I can see the voltage return to Pin 1, and the unit starts no problem.
Before I look for a replacement PSU (which seem pretty expensive), I was wondering if anyone knows if this is purely a PSU issue, or does the CUDA/PMU influence the standby voltages?
With the "sometimes" nature of the problem, it could be the front panel board, a much cheaper replacement than a PSU. An Apple tech told me that one way to test the front panel board was to find one of the first Apple USB keyboards for the original iMac. The early ones have a power button like the old ADB boards that overrides the internal board/button. He said that, should the Mac start reliably from the old keyboard, then there is trouble with the front panel board. The Apple model number for the USB board with power button is M2452.

You'll need a multimeter to check the voltage levels.

I have not checked the PSU, but plan on doing that soon. Just seems odd that it only has issues when the machine was shutdown. Seems to start after it sits for a while, but last night I was switching monitors, and shut it down, switched monitors, and it would not re-boot.

Power Mac G4 Won't Boot after Installing 2nd Hard Drive and Additional RAM
Hello. I am using a Power Mac G4 (PCI graphics) that I bought a few weeks ago. It was working perfectly fine until I tried to add an additional hard drive and add more RAM to the machine. After I closed the case and plugged it back in, it won't start up at all. No sound, no lights, nothing spinning, nothing. I removed the added hard drive and RAM, but it still refuses to start. I don't know what happened. Hopefully it's not a logic board failure or anything else equally bad.
Welcome to Apple Discussions!
The PowerMac G4 PCI forum is over here:
http://discussions.apple.com/forum.jspa?forumID=586
I'll ask a moderator to move your thread. Try replacing the clock battery, and hitting the CUDAS switch. -
Macbook late '08 freezing up, has trouble booting after iLife install.
A couple of days ago I installed iLife '11 on my Macbook and went to run the updates that the App Store was telling me were available, including the Mountain Lion 10.8.4 update. I shut the lid of my computer while they were downloading, without thinking and when I opened it again, the screen was dark, but the computer was on. I forced a shutdown and went to reboot but got stuck at the grey Apple logo and timer wheel. I zapped the PRAM and it booted right up but it told me that I needed to restart to install the updates. I did so and had trouble booting again. I had to do the PRAM thing a couple more times to get it to boot but when it did, the only update that installed was GarageBand. I ran it until all of the updates had downloaded and it asked me to restart. Everything went smoothly this time but when I logged back in the OS X 10.8.4 update was sitting there waiting to be installed again. I reset to install twice more but it never installed. Now whenever I'm running an application it will freeze up after a time, and when I go to quit the application the whole computer freezes, forcing me to force shutdown but putting me back to where it freezes on boot up. Freezes when I try to boot into safe mode or recovery mode often as well. I can manage to get in every once in awhile, after zapping the PRAM two or three times, but even that is starting to freeze too. Any one know what's going on? I ran iAntiVirus and it found nothing, I'm working on uninstalling iLife to see if that helps too.
I'm running Mountain Lion on a brand new Toshiba 1tb external drive connected to a Late 2008 aluminum unibody MacBook that I bought off my friend's dad back in March. No internal drive because the one that was in it failed in May.Let me start by saying do you know how easy it is to replace the hard drive in that MacBook? http://www.ifixit.com/Guide/MacBook+Unibody+Model+A1278+Hard+Drive+Replacement/8 16/1
First thought is to dump the anti virus software. It sounds to me as though your installation of OS X is hosed due to an incomplete update attempt. You need to repair the hard drive using Disk Utility and reinstall Mountian Lion completely, not just the update to 10.8.4. -
My Windows 2000 machine has trouble booting up after instaling PCI-6503 card
After I installed the card in my Dell Desktop has trouble booting up. I have to pull the power cable out and then reconnect for it to come up.
Hello;
The best way to go about that is to completely uninstall the NI-DAQ driver you have installed on that machine, turn the computer of and remove the board from it.
You then reintall NI-DAQ, and put the board back. If the same behavior shows, the best bet is to search for some other peace of Software/Hardware currently installed on the machine that might be conflictant with NI-DAQ.

Power Mac G5 won't boot with Lion?
After installing Lion, my early Intel 2010 Power Mac G5 won't boot. There were no problems for the first 2 days. The third day my G5 wouldn't boot at all. Not using Lion's recovery function, many attempts to boot from a previous system disk, and firewire target mode. The keyboard seems to be dead after attempting to boot except for the DVD eject key. All I get is a grey screen with an icon of a folder with a question mark within the folder. This icon blinks on and off continuously. Since the keyboard isn't working, I can't reset the PRAM, start in safe mode, or any other keyboard commands. The failed boot doesn't even get far enough for the Apple window to open. I replaced the hard drive and accomplished nothing except for spending even more money and time.
This is VERY frustrating! Has anyone else had a similar problem with booting after Lion't installation??
Thanks.1) you have a Mac pro Early 2009, remember this. It avoids confusion here in forum
2) you're HDD's OS cannot be found by the firmware of the Mac hence it results to a question mark
perform the following(recommended to use a USB keyboard)
a) startup manager
press and hold option on startup. Do u see your HDD?
b) if you have a back up of your data then you can boot to the install disk and perform an erase and install
repairing the permission will not work since the disc's OS is different from the HDD's OS. -
Why does my Power MAC G4 keep restarting itself after I shut it down?
Hi,
Thanks for reading this.
Why does my Power MAC G4 keep restarting itself after I shut it down?
This JUST started happening only 4 days ago.
Most recent installation was Limewire, but I removed it to see if this problem would go away.
I have 3 internal drives (See drive types below) that all have OS 10 on them in order to be able to boot up from either drive in the event of trouble.
However...
No matter WHICH drive I use as the start up drive... the computer STILL restarts itself after it is properly commanded to shut down.
Prior to the Limewire install... the ADOBE creative suite was installed.
There is a Lexmark X83 printer hooked to the computer, which, it seems doesn't matter if it is left on or off... the computer still restarts itself.
Any ideas?
Thanks!

If you still have problems, trash the following three preference files, then shut down and do a PMU reset. (PMU reset procedure for the QS is the same as is shown at the link for the Gigabit Ethernet.)

Windows XP SP2 freezes and then has trouble booting up
I've got a recent problem with my PC freezing while in use. All of a sudden it freezes with no error messages. The only resolution is to reboot the PC; however, most times the PC has trouble booting up after that. Usually at some point before it boots up I'll get a CMS checksum error, hit the F1 key to continue and Windows will load up. I'll have to restart it multiple times before I can get it to boot or I have to unplug the PC, let it sit overnight and then it tends to boot up with no problems the next morning.
I did notice that the fan to the PSU isn't running all the time. Should it be? I would have thought so, but don't know for sure.
I haven't tried reloading Windows over the current installation. I have an original Win XP disk ()non-SP2). This is a Windows CD, not a restore CD. I've updated to SP2. Will it be OK to reinstall over it with an older version of XP? I guess I can just not replace any newer files if it asks?
Thanks for any feedback.Quote from: crushert on 21-January-07, 00:20:05
Bosskiller, I just know the basics of hardware installation and such. I can put them together, but don't have much knowledge in diagnostics. The Geek Squad ran the basic diagnostic package and said everything checked out OK and that it was most likely a mobo or processor going bad.
I see you linked to an earlier post you made. However, if the memory checked out OK and it's run fine for the last 6 months without any problems, would it do any good to run another memory check on it?
"Bosskiller, I just know the basics of hardware installation and such. I can put them together, but don't have much knowledge in diagnostics. The Geek Squad ran the basic diagnostic package and said everything checked out OK and that it was most likely a mobo or processor going bad."
suggest you to ignore "The Geek Squad ran the basic diagnostic package" and to test it personally.
get memtest http://www.memtest.org/download/1.70/memtest86+-1.70.floppy.zip
extract files and make diskette bootable from installer. then reboot PC and boot from floppy, select test n5 only from there and leave it to test over 20times ensure no errors will come... step by step with memtest: https://forum-en.msi.com/index.php?topic=103598.msg760534#msg760534
other way is to try to install XP with each memory sticks separately until works.. leave only one stick into DIMM slot close to CPU socket and have a try to install OS again, if no go remove memory and replace it with other one. and retry.
or take PC to some computer repair shop to diagnose. -
I recently purchased a power mac mdd dual 1ghz processor. I'm trying to install 2 additional hard drives to no avail. I dont have the additional bay which is located under the optical drives is there away I could purchase one or some how work around not having this bay? Also I can not remove the bay which houses the original hard drive. I'm seriously stuck any suggestions
When it comes to the drive bay which houses your current hard drives, there should be a white plastic catch on one side. If you lift this the drive bay carrier should lift free.
As for your drive bay under the optical drives theres little you can do but buy a new drive carrier in think. Here is the link to purchase one though this is UK so im not usre whether it will suit your needs.
http://www.applemacparts.co.uk/store/productinfo.php?cPath=7445_7475_7601_7602&productsid=64530
The price is quite steep sadly because i think its a case of they have it and you want it so they can charge what they like. Other than that theres one going on ebay.com substantually cheaper here:
http://cgi.ebay.com/Hard-Drive-Carrier-for-PowerMac-G4-MDD_W0QQitemZ130116985516 QQihZ003QQcategoryZ51035QQrdZ1QQssPageNameZWD1VQQcmdZViewItem
When installing your drives make sure they are setup for 'cable select mode'
this is very important as if they are not it can cause all kinds of problems. This is dont by changing the pin jumpers on the drive which should have instructions on it as to what pins do what.
If your Powermac hasnt had drives in the lower bay before make sure you reset the PMU after you have installed them otherwise they wont mount, or thats the problem i found anyway. This will reset your date and clock so you will have to correct those when you power up but it more importantly resets the power management so you hard drives wil power up. Instructions on how to do this can be found here.

System disks for my power mac mdd g4 1.4 dual processor
i bought this power mac mdd g4 1.4 dual processor off from craigslist,no disks at all he didn't have them,so where can i get the installation disks?
Apple's Customer Service sometimes has OEM disk sets for older machines.
www.apple.com/contact/
Chances are slim, though, that they would have them for a machine that old.
You can find retail disk sets for older OS X versions at places like HarcoreMac, but their prices aren't cheap. EBay and CraigsList are other possibilities.
Your G4 MDD dual 1.42GHz machine is termed the "Power Mac G4 (FW800)" model by Apple. It originally came with OS X 10.2.3. It's max OS is OS X 10.5.8, the one apparently on it now.
Since the machine is running OS X 10.5.8, you should probably seek a retail OS X 10.5.x (Leopard) version. -
Power Mac g5 hangs on boot up when hot
My Power Mac G5 hangs on boot up when hot, such as after I have been using it a while. It won't get through the boot up process and I have a blank (dark) screen- no picture. Sometimes the little Mac chime sound doesn't even complete, and it quits abruptly 1/2 way through the sound.
Once the machine cools it does start... at least so far.
Any thoughts?
keithAny Extra Ram, Extra Peripherals, Aftermarket Video Card?
Will it boot with a CD?
When was the last time you checked the RAM in "About this Mac?"
Can you monitor internal temps thru software ?
Possible bad ram, bad power supply, bad video card.
Try removing an extra add-on components and see if that helps.
Also, I've found startup freezes can corrupt HD start-up files badly.
Just had similar issue in my single processor, ancient 1.6 Gig G-5.
Bad Radeon Card. Put the original back in and it works fine.
Google "G-5 Power Supplies" and check out the information....known issue.
Good Luck -
My Mac Mini does not boot, after backing the enire system onto an external drive with Carbon Copy Clone. I had switched the start-up disk back to the original of course. Now all I see is the Apple logo. What should I do? Thanks in advance.
Try disconnecting any external devices, especially hard drives
and try rebooting.
If that doesn't help, then :
If you are running Lion, boot to the Recovery HD and run a
Repair Disk on the OSX partition.
If Snow Leopard, boot to the installl DVD and run Repair Disk.

My power mac G5 won't boot up but has red flashing light and intense fan noise.
I Have a Power Mac G5 that flashes a red light that I've never seen before. There is nothing on the monitor and the fan noise is incredible.
HAs anyone ever had this problem?Hi Michael,
It's normal for the fans to go full speed if the OS won't load to handle them.
Where is this red light, on the logic board, or front panel?
Can you count the beeps or flashes?
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
5 beeps = processor is not usable
In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.
Note: In this case, a flash is considered to be 1/4 second or 250 ms or greater in length.

Power Mac G4 not turning on after clean shutdown, works otherwise.
My Power Mac G4 does not turn back on after a clean shutdown, but turns on after being disconnected from the power. If I shut it down cleanly (Apple menu -> Shutdown), it shuts down, but then the power button does not work. After unplugging the computer and plugging it back in, the computer is able to power on successfully. I have reset the PRAM and have reseated the PSU connector.
I am using Mac OS X Tiger 10.4.11, but the same problem occurs under Mac OS X Leopard 10.5.8. I don't think the operating system really matters with this type of issue though, because the power button literally will not respond until I unplug and replug the computer.
Any suggestions?

Mac mini won't boot after RAM upgrade.
Tried installing new RAM in my Mac Mini, 512MB stock to 2GB of Crucial. Followed the directions to a T, grounded myself the whole time.
Things I've tried so far:
1. Resetting the PRAM, no luck.
2. Holding option at start-up, shows no icon.
3. Holding shift, no luck.
4. Holding X, nothing.
How do I get it to accept a CD if it won't boot?Welcome to Apple Discussions!
You clearly have a problem, but you don't describe exactly what that is other than that your mini won't boot after the upgrade. What happens when it starts up? Does it attempt to start and hang up on the grey or blue screens, or does it start beeping at you almost immediately after you try and start it up, and also flash the power light?
If the former, then you may have dislodged a connector while working inside the system, in which case opening it up and checking that everything is firmly connected would be the first thing to do. If the latter, then the beeping/light flashing is the system telling you it has failed the power-on self test and the pattern of beeps/lights indicates why. In your case likely the system can't find workable memory. In that instance, opening the system and ensuring that the RAM is firmly and fully seated would be a good step, and if the mini continues to fail, then replacing the new RAM with the original to test that the system will then start.
It is not likely that anything had damaged your MacOS install in the process of upgrading, thus normally no reason to need to boot to CD as a result of a RAM issue.
