I have a G5 Power Mac dual 1.8 running 10.5.8. It powers a radio stations automation system. I have it set to power on after a power failure but for some reason it will not power on. I have to come t the station and reboot the system manually.
View 1 Repliesa friend recently gave me a g5 power mac that had some issues, and the failure was described as intermittant. The machine supposedly would work properly when booted and start freezing up after time, but if turned on the next day it would work properly for some time. I assumed it was an overheating issue, but apperently there is more to the picture. I have tried booting the machine quite a few times and the display always reads no signal. The machine sounds as if it were booting normally, but there is not output. At first I assumed it was my display cable, which was a DVI-D single link, however the DVI-D dual link cable leads to the same result. Is it nessicary to have a DVI-I cable? None of the error LEDs light up on the motherboard. After doing some hunting I haven't found anyone with the same issue, but I am wondering if I should assume the graphics card is dead. What steps do I need to take to isolate a graphics card failure in a power mac g5?

G4 733 D/A , 10.4.11. This morning there was a few second power failure according to my wife. Ther G4 shut down from the power failure. I didn't have "restart after power failure" selected in the Energy Saver prefs. I restarted the G4 when zi got home and after I was done with it, selected SLEEP from the menu. The G4 wouldn't respond to sleep. I logged out and tried SLEEP from another user acc't and from the login screen. I then went into the Energy Saver prefs, made sure everything was as I wanted ( 5 min display sleep, 10 min HD sleep, and "put disk to sleep whenever possible". I then rebooted and sleep still wouldn't function.

why i have to unplug the power cable from the back of my imac after every power failure at my home to get the imac to boot up. I've tried resetting the surge protecter and unplugging there. However, the only option is to unplug the cord from the back of the monitor/imac before it will boot up.Â

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.

It has started misbehaving slightly: it usually takes two or more tries to start from off, and has to have a hard restart if I've let it go to sleep on its own.If I have made it sleep myself, by pressing the power button, it always comes back, but it refuses to do so if I let it sleep on its own.My local reseller suggests that it may be a logic board fault: I'll have to pay ?70 to diagnose this and, if that's the case, the repair is uneconomic, meaning I've also wasted
View 1 Replies View RelatedI 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.
View 4 Replies View RelatedI have a PowerMac G5 computer, running OSX Version 10.4.11. Up until yesterday, the computer performed flawlessly. Suddenly, yesterday, I get a message from Firefox (the browser I usually use), telling me that my Flash Player had been disabled because I did not have the most up-to-date version of Adobe Flash Player. When I investigated, I found out that the newest version was NOT compatible with my computer. So I tried reinstalling the most recent version of Adobe Flash Player that IS compatible and have had no success. When I go in to System Preferences and click on the Adobe Flash Player pane (under other), I get a message reading "could not load Adobe Flash Player." Someone out there must know how to handle this. I'm not in a position to purchase a new computer, and I desperately need Flash Player for some of the websites I use quite often.

I picked up an 802.11n Airport Express card for my Mac Pro last week. The installation went fine, but my Netgear router was only 802.11g. So I felt the need to get an Airport Express now that it?s been updated to ?n?. First I plugged the AE into my switch along with my networked printer, cable modem, and Tivo. My 1st gen MacBook showed me full bars and was very happy. My Mac Pro only showed 2 bars. They are side-by-side and about 20 feet from the AE. Strange. I plugged the AE into an extension cord and moved it closer to the Mac Pro. Still, after the AE completes its POST, I get full bars on the Mac Pro. As soon as I hop on the internet, it drops to 2 bars. It?s really weak and pages take forever to load. Sometimes not at all. The MacBook is still fine.
My wife being used to PC nightmares at work suggested that I reboot. ?Heresy?, I said. ?I shouldn?t have to do that. It should ?just work?.? From the Mac Pro, I turned Airport off and then on again. Full bars again. As soon as I hop on the internet, it drops. So what?s up? Much to my lament, I rebooted. Bingo! It works. Full bars, all the time. So I moved the AE back to where I initially had it. (About 5 feet away next to the cable modem and switch. One less extension cord to deal with.) The AE completed its POST, gave me a green LED and I went back to the Mac Pro. 2 bars again! ERRRR!.............
I am having lockup issues with my new Mini. I changed the RAM to 3gb and a SSD. boots fine but completely locks up after a period of use. Only way to cure it is to force reboot via power button. Anyone here has the same issue or know what I should do?
View 7 Replies View RelatedMy IMac crashes sometimes very suddenly, like in a power failure. It doesn't force quit or shut down, it just goes like somebody pulled the plug. It's usually possible to start it up again after 30minutes or an hour. The plug and lead seem to be fine. I tested it on another mac. The obvious suspicion would be overheating, but how can that be caused so suddenly (and how can I fix it)? It's an IMac Intel core duo, 20", 2 ghz, 2gb ram from 2006. I'm running Mac OS X (10.4.11) 2006.

I have a 2011 MacBook Pro 15 inch, and the Messages application has been installed and functioning well for the past year. A few hours ago, my MacBook ran out of battery and died on me. This caused a number of applications to function incorrectly, however, after a restart all of the applications EXCEPT Messages work correctly. Now whenever I start up the messages app and try to send a message to one of my contacts, their name appears in red and I receive a message that says "###-###-#### is not registered with iMessage." This occurs even though the contacts DO have iMessage and were working in the past. None of the contacts work currently.Â
I tried signing out of Messages, restarting my computer, restarting iMessage from my phone, deleting my plist file, but none of these seem to alleviate the issue.

I've had my original MBP since 2007, which was originally on 10.4 I believe. I've done upgrades up to the current 10.7.4. My original MBP was encountering end-of-life hardware issues, so 3 months ago I purchased a new MBP. I used the Migration Assistant utility to move my files and user settings.My older MBP toward the end of its life was having OS shutdown / reboot problems. The OS would never completely shut down. It would go to a light gray screen, and the twirling icon in the middle never went away. A manual shut down from the power button was the only recourse. It seems that the issue is tied to issue(s) with my user account settings, since the problem is still present, despite newer hardware.I'm comfortable with reviewing my system.log in Console and issuing Terminal commands, if that will help with any troubleshooting.

I'm going to be setting up a dedicated server on a LAN soon. It's only going to be accessed by a handful of computers, all of which will be controlled by the client. Based on cost and complexity of other options, we've decided on a normal Mini, rather than a Mini Server or an Xserve.
The one feature that concerns us, which is included with the Xserve but not on either Mini, is the redundant power supply. We would like to avoid downtime in the event of a power supply failure. Are there any third party options to this?
(A battery backup with a limited run time would not be sufficient.)
I have a 17" iMac G4 that I was rung Tiger with, then I installed Leopard 10.5. I use this as a second computer. All is fine except that my Epson scanner does not work with 10.5. I've tried the latest drivers. I'd like to reinstall Tiger. I used the 10.5 disc to reformat the drive and start from square one. When I boot from my original Tiger disc it starts opening it's windows, but when I get to the point where I can choose Install or use Disk Utility to reformat from the Tiger disc, all windows freeze and I need to hard reboot from the power switch. Am I correct to assume that 10.5 won't let 10.4 to reinstall. Is this correct?

It powers down constantly and I was advised to check the box that restarts it automatically after power failure in order begin to ascertain what the problem is.
I cannot find the darned box to check!
I looked in the "energy saver" category where my computer tells me the box is, but there's no option anywhere to be seen.
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.
View 10 Replies View RelatedI 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.

The display shows no sign of life (no power light, etc) and the brick has been tested and is OK. My local service place says that they will have to send the display back to Apple which means a minimum of $400 for repair so I'm wondering if anyone has had a similar issue that they resolved successfully? The service place suggested that Apple would replace the logic board but is there any way to test to see if this is the main issue? I have seen logic boards sold separately online but would be hesitant to buy it without know that this would fix this issue.
