I have a G5 dual processor ((I think its a 2.5) running Tiger. I had it stored for several months and when I brought it out it won't start.. No response at all to pushing button..
Cord is good as it will power my display.
Something bad going on here. Dead hard drive(?)
Current status is...Cannot turn on, screen is dark. Blue light on power button stays on. Can't restart after holding it down...Red light inside box is on. Read that it might be air deflector trouble, but that's not it. Opened box removed plastic and returned it...another red light lit , then turned off. 1st red light stays on.
Before the above began, a restart would end up in a hang at the end of the progress bar. Ran Disk Util from Install CD which showed errors: "Volume Chk failed...HFS Volume needs repair". Ran FSCK whick said it fixed all. Ran Disk Warrior afterward b/c still would hang at startup. Says all now OK...but NOT! Have tried saving files thru Disk Warrior...but now, as per above, cannot get it to start up. Or turn off...
Would like to get it lit to save any additional files if drive is near the end...

I'm new here, but not new to the Mac world. I own an intel iMac and while I was attempting to restart it on Sunday night it went into a gray screen with the box asking me to shut and restart in several languages. I did and still get stuck on that page. I did a PRAM reset and that didn't work. So I used my start up disk to get to the disk utility and my HD is fine so I used an external drive to install the OS on it and reboot from and reinstalled from TimeMachine (only problem is the last time I backed up was 5 months ago)Again I checked my internal drive and everything seems okay, but I cannot reboot from it. BTW, I've OS 10.6.2,
View 1 Replies View RelatedI am using Mac 0S X Leopard, mac mini and facing the following problem:
1) System is taking too long time(10 - 15 min ) for start up and shut down.
2) It is asking every time to set up the current time as and when the system starts every time.
3) When accesing the system preferences , it gets crashed when using index Spotlight.
4) Finder gets relaunched itself for every 60-90 seconds when accessing folder Applications or Utilities etc..
5) The Spotlight is indexing itself, When i tried to stop the indexing of the spotlight using system preference, it gets crashed.
My system got its logic board replaced by the apple once.
my G4 will not power up anymore, and I have tried replacing the battery, the pushing the PRAM switch, etc. any other suggestions?
View 1 Replies View RelatedMy Mac attempts to start up and automatically shuts down on it's own. It continues to start and stop for several minutes and finally boots up. Once it's up it works OK. I've had it in to the Mac store and they tell me it's probably the power supply, but after leaving it on all weekend it seemed to work OK so they didn't do anything. After I brought it home it is still acting in the same way. It's only on trying to start up that it cycles through the start - stop action. Once I turn it off it's the same problem on trying to start again. Does this sound like a power supply problem?

I have replaced the ram with its original dimms. Still no good. I have also removed both the dvd and hard drive. Would be happy if i could atleast get the white light and mac sound... but nothing
I have a 20" Intel based iMac (model A1224) running Snow Leopard. It is just over a year old and only had the original Apple keyboard and mouse plugged into it. Today when I tried to start it I got only a blank gray screen. I tried all the keyboard combo start-up suggestions in the Apple help screens, unplugging/replugging everything, and booting with the Original disk and the Snow Leopard disk. A couple of those attempts produced a minute of the gray apple logo screen, then back to blank. While the disks were in it did sound like it was trying to read them, but spit out the disks after about 5 minutes.

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. Has it died or is it a more complicated software or OSX problem? I am running Mac OS X 10.5.8 (9L30) Kernel Version:Darwin 9.8.0 on my Mac. The DVD drive has been making some strange whirring noises occasionally as I ripped CDs to my hard drive.
The machine is in a very cold area, was on for about 10 to 15 minutes before it just shutdown (like the plug was pulled) I checked the powercord by using another , same problem. I try to push the power button but nothing happens.

View 6 Replies View RelatedOk, I know I've had 2 discussions here already but it still doesn't make sense to me. Everything says its a bad Logic Board. Ok, Power Mac A1074 2.0 DP It hangs at white screen w/ grey apple logo and no spinning wheel. I have ran the Apple hardware diagnostics disc several tims. Everything comes back that all hard ware is GOOD. I try and run the OS diagnostics on the same disc and it hangs at the white screen/grey apple logo. I have replaced the hard drive and started it holding 'option"it reads the Apple OS Install disc (just as it reads the hardware diagnostic disc just fine) when I try to boot from the install disc it again hangs at the white screen/grey apple logo with no spinning wheel.

I have a 1.8GHz G5 that will just not boot up. When I start it I get the grey screen with the Apple logo and nothing else. The fan then fires up and up. Have tried starting it in Safeboot mode. In this mode I can hear the initial chime and some activity for about 5-6 secs and then nothing. I have an extra 2GB of Kingston RAM in the machine that I put in a couple of years ago and apart from this nothing has changed apart from upgrading the OS's.

It was checked with another power cord too, no power at all. The battery has been replaced, still no luck. Who can repair it? I called a guy, he said to change the logic board that "could be" the problem is too expensive. Advice: donate to Salvation army......Nice, right.? I love this machine, even I have a brand new iMac, iPad, PowerBook, u name it! but it runs the Classic and I have all my files written by this op.. System.

I will start up my G5 and I hear the chime but at that point my CRD monitors never come on. The lights on my USB hub don't light up, either. Then my G5 fans rev up really high. I have to hold down the power button to get it to shut off, then after waiting around 10 seconds I'll try to turn it on again. After several times of repeating this process, my monitors finally kick on, the USB hub lights up and all is fine for the rest of the day. But it's really aggravating having to do this up to five times to get things going. It's like the G5 isn't communicating to the monitors or the USB hub.
Could this be a motherboard issue? It shouldn't be a power issue, as the only thing plugged into my battery backup APC is the tower itself. I'm at a loss here...

I received a semi working powerMac G4 Cube from a freecycle community, and while initially it worked fine, I had to dissemble the unit to replace the dvd drive which had a dvd stuck in it. I used one from a second unit that I was also given and I think the dvd is also bad , as placing the 'software installer', which I presume is OS9, causes dvd unit to make what sounds like spinning noise ( Does not sound to me like its reading anything ), and then after a few seconds it spits it right back out, and this happens everytime.Before I dissembled the unit, the cube at least booted into OS9 just fine, yet I am sure I put everything back properly. I might have chosen a bad setting in system perferences I suppose, and if so is there a fix short of getting a new dvd unit so I can reinstall OS 9 ? Also, I did try 'control' while startup, and it takes me to a very odd screen, with a icon for 'reload' ( browser icon similarity ) , or what looks like a right arrow. Choosing either does nothing, short of showing what looks like a watch moving in circular fashion.

My living space if very cold and quite dusty (warehouse). I notice it more on colder mornings ( inside temp 45° - 65°F ). Should I refrain from using my machine on cold mornings/nights until the heat is running?

I've got a strange issue with my PowerMac dual 1.8GhZ and I can't figure out where it's coming from.Last Saturday I experienced a Kernell Panic while using Safari and the Dictionary (MacOS 10.5.1).Since then, whenever I try to start my computer, it shuts itself down while the grey screen with the Apple logo is on screen. However, this isn't always the case:I can use my computer 'normally' if I press the option key at start-up and manually choose my startup disk.
I can boot from a Panther or Tiger installation disk, but not Leopard.If I try the hardware test the computer shuts itself down in the middle of the test.TechTool works and didn't find any issues with my computer. Nor did Disk Utility.I tried to erase both my internal hard-drives and do a clean install of Tiger, but the problem is still there (I have to press option at startup).I tried to reset the PRAM and Cuda/PMA. Doesn't resolve the issue.When I tick 'Restart automatically after power failure' in Energy Saver my Mac will indeed restart, meaning it thinks there was a power failure.Any idea what it might be? And why it only happens in certain situations?Do you think it's a hardware or a software issue?

When I start my computer up in the morning everything else starts normally. First the light comes on on the front of the computer and on the bottom of the monitor, then the start up tone rings and the computer is fully running. But my monitor is black and I do not get the apple picture or nothing on the screen. I thought my monitor was going out, but we have another work station the same and I switched the monitors (same 27" cinema screen as mine). I can actually use the other computer and network into my computer and fully use everything on my computer. But my monitor is black (no display)! I have contacted MAC and have reset the PMU button many times and sometimes this works, but most of the time it does not. I just keep restarting the computer and finally it will start up normally with the display and everything.

I am the original owner of a Power mac G5 dual 2.0 I purchased this machine in april of 2004 and it has been working nearly non stop ever since. Recently I put it into sleep mode and when I came back it had powered down and would not start up. I assume it's the power supply and I would like to know if there is anyway to tell what type of power supply and model thereof without tearing down the machine.

I have a big problem. For some months now I haven't been able to start up my Mac. It's a Mac PowerBook G4 bought back in 2002. It's a laptop. When I push the start button it shows me the grey screen with an apple. Then the screen turns blue showing the white and square icon with an apple, Mac OSX and the line for loading saying "starting Mac OS X..." When the loading sign is complete or almost complete it stops. Nothing more happens. It just stands there the blue screen with the loading line that looks pretty complete. What can be wrong? Some time ago I was asked the message: if I want to use the new way of starting up my computer, and I clicked YES, because I thought it was the normal software updating. And eversine then it hasn't been able to finish starting up. Can anyone give me suggestions of what to do? Or maybe tell me what is wrong? Maybe it has something to do with the "new starting up" message I said yes to, or maybe not.
I really hope someone out there can give me some advice, because now I haven't been able to use my Mac for months!
I have a G5 dual pro 2Ghz (June 2004), 1.5 Gb ram, Leopard
When I press the start button, the dvd drive spins, the startup disk "sparkles" (noise seems normal) but no image appears on screen (black monitor enabled), no start-music. It starts correctly after + / - 15 attempts ignition-extinction.
The various reset (pram, motherboard) have been tempted. "Cleaning" the computer with Onyx (maintenance). Battery voltage Bios = OK. The authorization of repairs were made. Repairing minor problems in head volume repaired (the install cd has booted). Tempted to start with a minimum of devices. The symptoms still persist for 2 to 3 weeks.
I have installed a new hard drive. I've installed Leopard on it.
But the problems stay. My mac starts when he wants...
Tried to wake my 24" white iMac from sleep yesterday and discovered that it was off. Pressed the button in back but no go. Unplugged and replugged, pressed the button and it fired up fine. Surfed a bit, then put it back to sleep.
Came back about 3 hours later and it was off again. Unplugged and replugged, pressed the button and nothing. Tried it a couple more times just to check, and no go.
Any ideas? I've had this computer for a little over two years. Bought it used and bought Applecare which expired on.... Nov. 16th. Beautiful timing or what.
I have a G5 Dual 2.5 and the power light on the front (white) is lit but nothing happens when I press the power button. I was trying to reset the PRAM manually by pulling the battery and inplugging the unit because my startup shortcut keys were not working. I had seen it recommended to reset it by pulling the battery and reinstalling in other threads. I put the battery back after about 15 sec and plugged in back in. Now it wont start up.
View 1 Replies View RelatedSilver front G4 won't start up. Recently replaced back up battery when this condition occured, start up fine. Computer was turned off for about 2 weeks while out of town, but now the on button lights momentarily, no boot uo. Won't even do that unless power cord is removed and re-inserted.
