Power Mac G5 :: No Boot After Initial Turn On - Fan Goes Haywire
Nov 27, 2007
And then open the begger up to find the Serial number, prod a few things, close up, then it starts? Anyone advise what's going on. Could it be it was too cold? My office gets cold? Could it be that I am turning the plug off at the switch when I don't use it and then it sometimes is bad to start up after a few days. Someone be strict with me and tell me what I am doing wrong (should I even be turning it off at the switch once turned off?)

My wife has a brand new MacBook (her first). During the initial boot process, the Mac took her picture (of the dog licking her face). Where is that picture stored? We need to upload it to Facebook.
I put custom icons in place of alot of my folders and other things in OSX, the problem is that after i changed the Finder icon and then booted up in safe mode to make it change like i was told to do my Safari Firefox and Garageband icons have all gone missing. and have been replace with the generic app symbol. the ICNS files with the new icons are still in the right folders, they're just not showing up...
i just got my new imac 2 days ago. I was wondering is there another to turn on the power without pressing the power from button? (cuz i remember u can power on from the keyboard b4)
I 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.
This is bad and old, and full of lessons about backing up. Anyway, internal boot drive crashed a week ago, and internal optical drive is busted. New external LaCie dvd burner works fine, but all attempts to start up from Tiger, Leopard and Diskwarrior installation disks just end up back in OS10.3 on my external LaCie FW drive. I've tried many things: unplugged everything; switched external LaCie to USB (wouldn't boot), unplugged power from internal optical drive so Mac wouldn't look there first (somebody suggested that). Attempts to start up installers from mounted DVDs result in installer screen with restart button, which, when clicked on, results in... you guessed it... boot back to dreaded 10.3 system. Night owls and westcoasters, I am up for hours yet, pulling hair.
Recently, I was using my powermac (About 1-2 weeks ago) and I went on vacation. I came back and it won't turn on. Everything's plugged in, and the power buttons and lights on the mobo light up. I can hear the HD spin up, and begin to read. But, I don't get any video. I've read that it could be the battery and so i replaced it, but it still won't turn on. I've reset the CUDA, installed different RAM, took out expansion cards, but it still won't turn on. Also, when I press the power button it immediately shuts off, which it never used to do. I usually have to wait at least 3-4 seconds of holding it down.
my old 2x2Ghz PM G5 (late2004) doesn't launch the boot sequence:
- when pushing power button, the blue led turn ON as long as I keep it pushed. If not pushed, it light off but yet the fan are running.
- no chime
- the fans turn on normally and the hard drive start a little to make noise once powered up.
- no video on display, the screen is black.
- the keyboard is not recognized anywhere I plug it.
- after a minute or two of non activity, the fans start to blow full speed (guess its a security measure for saving processor)
I ve done the reset of PMU several time (unplug the power cord then push the button at bottom of mother board)As i dont have access to keyboard, I can't start on Target mode to check if the HD is failing all.I ve removed all RAM extensions and left only one pair in slot 1 (J0), and changed the pair to avoid a faulty RAM.I only have a redlight on motherboard if I don t put back the glass panel.I ve check the voltage of the lithium battery, and yet its the original, the voltmeter says its 3,6V...
I recently purchased a Power Mac G5 Dual 2GHz from ebay. I tested the computer a couple of weeks ago when I first got it, but wasn't able to actually set it up with all of my music gear until last night. I installed Logic Studio and a driver for my firewire audio interface and started downloading all of the updates. While downloading the updates the computer just turned off. I wasn't in the room, but when I came back in it was totally off. I tried to turn it back on by using the power button in the front and it won't turn on. It clicks once then clicks again a few seconds later, but no light and no power. Everything else that is plugged into the same power strip turns on. I reset the PMU, and even the graphics card just to make sure. I still get nothing. I have exhausted apples support page, and I don't know what else to do.
I recently purchased the Bluray for "Haywire" that included a digital copy. I have followed the directions for download into iTunes included w/ the Bluray that directs me to www.lionsgatedigitalcopy.com/redeem. I have entered the code on multiple occasions w/ the same result - Session Timed Out in iTunes. Has anyone else experienced this problem? I have contacted Lionsgate support and they say they are not distributing "Haywire" in the US and therefore cannot help.

I have a PowerBook G4 1.67 that shut itself down sometime during the day yesterday, and will not power back up. It's completely unresponsive to the power button, with no signs of life whatsoever.
I've tried resetting the PMU. There has been no new hardware or software installed. This has been tried with 2 batteries, and 2 AC power supplies.
There is inconsistency with the color of the AC power supply tip, as it doesn't seem to indicate the strength of the battery. Regardless of which battery or how much charge is left, the tip is Green, and will flicker Yellow very quickly once, when plugged in. It was Green following the initial shutdown, Yellow when I placed a dead battery in it, and then eventually turned Green. Now, it seems permanently in the Green / flicker Yellow state.
Using my iMac today working away and all of a sudden the screen went black, there was no power to the computer at all. I have checked the fuse and that is ok. I am getting power to everything else. I reset the SMC as per Apple instructions on their website. Again nothing.
I then left it turned off for a good 5 mins and then turned on the power. The fans turned on and the mac then chimed, the creen came on and I thought everything was ok. Then the computer turned off, fans and hard drive sped It didnt even start booting to the Apple logo or the log on screen.
I am thinking this is a power issue within the computer and this will need to be replaced. I was wondering if anyone else has had this problem. My iMac is a 2008 21inch iMac. It is connected to a APC UPS which again all power ports are working, as I have tested that with a desk lamp. What I do normally is turn the UPS when I have shutdown my Mac in the evening and then power it up next day. While the UPS is doing is power self test I then boot the Mac, I am wondering if I should just leave the UPS turned on all the time and just unplug my iMac when I am not using it. Sometimes I do pop it to sleep last thing at night, but recently I just turn it off.
It has had heavy use so I am wondering if it is indeed curtains and I need to buy a new iMac. Maybe it is an excuse to buy a 27inch one! (Would be nice)
I have a white 2008 model MacBook. Due to some unfortunate tampering with the circuits under the right command key on the built in keyboard, a lot of the keys and the power button are now effectively dead. I'be ordered a replacement top case, but was wondering if I could, in the meanwhile, somehow turn the laptop on. I'd prefer to do this without opening it up, though I could if that's the only way.
I read in another thread, can't find the link now, that disconnecting the battery, connecting mains, then connecting the battery would turn it on, but that doesn't seem to work for me.

Does anyone know if there's anyway to turn on an aluminum powerbook without the power button? I mean is there any keystroke combination that can turn a powerbook on?
I left my iMac on overnight last night to finish downloading some stuff. I woke up and all our clocks are flashing, so we must've had a blackout. Anyway, I went to check the progress of my downloads, and the iMac was off. I pushed the power button and nothing happened. No fan noise, HDD noise, nothing. I've been trying for almost two hours now and nothing is working.
My MacBook pro (15" unibody, non-removable battery) will not turn on. The battery claims to be fully charged. The computer will not respond to the power button in any way. I had turned it on previously by draining the battery completely of any charge (draining power, then pressing and holding down power button for 60 seconds). When this occurred the computer booted up and ran fine. However, when I closed the lid, it turned off immediately, never to return. I'm wondering if this is a problem with the battery, or if it's a problem with the logic board.
my G5 was in sleep mode during 2 power outages. She will not turn back on, have tried unplgging, wait then replugging and turning powerstrip back on. Also tried holding down command,option, p & r keys along w/ powerbutton..I'm on my kindle fire rt now, but definitely need my Mac back up.
last night I was using my computer just chatting with people, then all of the sudden it shuts off. Now it won't boot past the apple grey loading screen, and the fans slowly rev up till they are full boar, and I have to shut it off for them to stop. I've reset the PRAM, the SMU/PMU, tried holding alt and selecting my drive to boot to. None of these did anything, and didn't help at all.
I've heard it's a processer or logic board failure, or a HD failure, or something else. I'm ready to buy a new computer, I'm actually kind of sick of this one, I just want to know if I can fix it or not. I will probably take it to the apple store just to make sure, but maybe I can get an answer on here to know how to fix it or just to know that it's dead.
Just got a replacement imac 27 stock C2D yesterday for a defective one I had earlier, however, I couldn't get this new one to turn on till just a few hours ago. I just figured out the power button needs quite of bit of pressure to turn on. Seemingly just pressing it until it clicks isn't enough. Should this be looked at or is this normal?
So I'm having issues with the computer not waking up in the morning. I guess it goes into a deep sleep of some sort and I have to hold the power button twice to turn it on, and get greeted with a computer experienced a problem message on login.
The most recent log in the system diagnostics is titled:
A few hours ago i tried to turn it on but it only showed the apple screen for a few seconds and turn off automatically.. i can't turn it back on anymore..
It doesn't response to the power button nothing happen after pressing the button. I am sure it is charged... what should i do..?
