G4 startup chime=ok, video=no, keyboard commands=no

Hi everyone.
I have a dual 1ghz mirror door G4 that stays on most of the time. Last night it was working fine but this morning it wouldn't wake from sleep so I shut it off by holding down the power button. It will occasionally freeze at night, so this didn't seem to strange. Now though, it makes the startup chime and the fans (and maybe HD) makes some noise, but no video displays. Startup key commands are also not working and I cannot get the cd drive open (it is empty now), but even if I could get a disk in there I couldn't get it to boot up without the keyboard working.
So far I have tried:
unplugging all peripherals
leaving everything unplugged except the keyboard and monitor
removing the battery
resetting the pmu
removing non apple ram
resetting pram doesn't work
Does anyone have any suggestions? I really appreciate your help.
Thanks,
Rob

Well, no luck with inserting the Tiger install cd and disconnecting the hard drives. Like I said, everything sounds normal when starting up the computer, the fans go on and you can hear the hard drives and cd spinning.
I have tested the keyboard on another computer and it is working, but when starting up the G4 eject, resetting PRAM, cmd-c, and cmd-t don't work. The monitor as well sits idle (with the LED yellow) when you disconnect the monitor cable it turns green and says no signal and check cable. Once you reconnect it it goes black again with the LED changing back to yellow.
The startup process is initiated by the firmware and therefore regardless of having a functioning OS, hard drive, or cd drive, something should come up on the screen and key commands should work.
Hopefully this isn't something major like the motherboard going out or something similar. I am certainly no hardware expert, but it seems like something along those lines.

TS1367 My PowerMac G5 will not start up. There is no startup chime, no display and the fans speed up and sound like and airplane after about 30 seconds. Can someone help?

I push the power button, and it turns on, but there is no startup chime, no video display, and after 30 seconds, the fans spin up. Any ideas?

G5 has these hardware issues:
-- bad capacitors on logic board
-- bad capacitors in power supply
-- badly soldered video chip
-- "There were several Mac models with flat panel displays that had bad displays.
     Most had serial numbers beginning with "W8"---the code for one specific factory.
     This affected PowerBooks as well. If that's the case, the rest of the computer
     is probably fine." by Allan Jones in

Startup with CD - keyboard command?

Hi,
I need to do regular maintenance on my Macbook. However, I cannot start it with the CD (Disk Warrior) the way I do with my other Macs. I use the keyboard command Command C on startup. How do I do this on my Macbook?
Thanks,
Jeanie

If you're not having problems, you don't need to do any real maintenance; your machine should be taking care of itself.
Are you holding down the C key as soon as you turn on the computer? Does holding down the D key do anything? That's supposed to bring up the hardware test.

Mac mini won't boot, shows no video, no startup chime, startup light is on

Hello everybody,
I have a strange boot up problem with my Intel Mac mini. I think, the problem appeared after the 10.4.7 update and I believe I installed the first installer, which has some missing graphics drivers.
Anyway, the problem is that when I want to start the mini, the light at the front goes on and that's it. No startup sound, no video, just a little sound from the fan (very calm). I already resettet the NVRam, used a different monitor, resetted the PMU and the SMC. Between all these resets, sometimes the mini changes its behaviour. It then turns on the fan on full speed, the light stays off and still no video and sound.
Has anybody any tip for me? Every tip is greatly appreciated.
Mac mini Core Solo Mac OS X (10.4.6)

Ahem...Don't know how to say that but to make it fast I had the very same problem with my core duo after 3 weeks of use, and in my case it had nothing to do with 10.4.7 update (not published at the time). It ended up taking back the mini to the Apple Center for service : motherboard had to be changed.
The mini has been fine since, very happy with 10.4.7 update !

Why is the startup chime so loud on my iMac?

I just bought it yesterday from the Apple store, so it's brand new.
I find that the volume control does not influence the startup chime.
I've looked on-line for solutions, it seems others have this same problem. I've tried "zapping the PRAM" to no success.
Keeping an audio plug installed in the headphone jack does not disable the internal speakers from booming the startup chime.
Does anyone have a solution to this please? It seems silly that such an expensive computer should have such an uncorrected problem.
Thank you,
geo

Well, my volume control certainly does influence the start up chime and I cannot see why yours shouldn't. Use keyboard buttons F11 and F12 to adjust your sound level last thing at night and if your machine auto starts in the morning it will not wake the household.
True, if volume control is turned down to a lower level, you would have to adjust it for other sound output that you do want later, iTunes and videos on browsers etc, but it requires little effort.

Startup Chime Missing

H, Since I installed Snow Leopard my computer hasn't chimed when turning it on. It's a small thing I know, and the computer is fine in every other way but I just wondered if anyone else had seen this.
Thanks
Weenie

I had this problem recently. If you have the system volume up and you're still not hearing the chime. Try resetting the PRAM.
1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need them in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys before the gray screen appears.
5. Hold the keys down until the computer restarts and hopefully you should hear the startup sound.
6. Release the keys.

Startup Chime and volume

Since upgrading to Snow Leopard, whenever my computer is turned on the chime is very loud as well as volume once logged in. I deleted the soundpref plist, however the problem still persists. Any suggestions?

Ok.. try resetting the PRAM/NVRAM, instructions here.
Restore PRAM and NVRAM to Defaults :
1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6. Release the keys.
7. Your computer’s PRAM and the NVRAM are reset to the default values.
It corrects ...

Problem with overwrite and insert keyboard commands

I'm a new user, switching from FCP. I edited one project successfully with no trouble a couple of weeks ago. Now I'm in a second project and having a weird difficulty. Using a pretty new Mac 8 core tower.
The insert and overlay keyboard commands (comma and period keys) don't work. They still work in the old project but not this one. If I start a new sequence and copy my timeline to it, the commands will work for awhile but ONLY with video, not with the audio tracks. Drag and drop works fine but that really slows me down.
The clips I'm using are all the same format (H.264 from Canon 5DII and some still photos) as the first project. Only difference in this project is lots of chroma keying and some resizing of background still photos. Nothing unrendered.
I started a new project just now and imported the problem project into it, started a new sequence, copied old sequence, and I get the same problem. I can drop in video with a keyboard command but not audio. Earlier it was not even doing video. Yesterday when I'd start a new sequence and do the same thing, it would give me video on the keyboard command but then eventually that would stop and it would do nothing. At one point the cursor would move over the width of the clip, as if it had been dropped into the timeline, but then that stopped as well.
I've trashed preferences and that didn't work. I did that according to a procedure I found online. It said open up PP while holding down the Shift and Option keys. I did that twice. Nothing.
To summarize: Keyboard commands for overwrite and insert edit do not work in this project but do in an older project.
Any ideas?
Thanks.

Well, thanks to an email from another person who was having the same problem, it's all solved not.
Operator error. Dang. Who knew--in FCP you select a track by clicking on the V or A buttons to the far left. In Premiere Pro you have to make sure BOTH the far left button and the one to the right that says Video 1, Audio 1, etc. are also clicked. They BOTH have to be light gray. In my first project, everything was properly activated but in the next project apparently they were not and that carried over to succeeding projects (even though I didn't change anything...at least consciously).
So all as well now. No glitch, no bug. Just good ol' fashioned operator error. I will wear the dunce hat today.

Mac Mini won't boot, distorted startup chime, gray screen

Hi all --
I've seen similar posts (http://discussions.apple.com/thread.jspa?messageID=12170891&#12170891) but thought I'd start a new one, mainly because I haven't heard anyone mention the startup chime.
I woke up my 2007 stock Mac Mini Friday morning and the cursor was frozen. Unplugged and replugged the mouse to no avail. Couldn't force quit, so I had to power down. Restarted with a badly distored startup chime (not "speaker breakup" from excessive volume, just distortion, and some "stuttering") and a gray screen that didn't go away. Restarted many, many times. Inserted Snow Leopard DVD to run Disc Utility but it wasn't recognized -- just a gray screen. Tried resetting the PMU and SMC with no results. Tried booting into single-user mode (with a wired USB keyboard) to eject the DVD, but no luck. Tried open firmware, but nothing. Once in an while I would get the Apple icon and a spinning progress bar that never went away.
Took it to the Genius Bar, where they tried to boot from a Firewire drive, with no success. The best they could do was tell me my 17-month old Mac was out of warranty. That confirmed, I took it home, cracked it open and removed the Snow Leopard DVD (with a credit card) to insert the install disc it shipped with. That didn't work. A couple of times it looked like it would, but then after the spinning bar I got the multilingual system bomb message. Tried to run Hardware Test, but nothing. Put in original Disc 2... and that gave me a flashing folder! Progress! Forced the DVD out and slipped in Disc 1. That started to read, and then I got some kernel-panic looking text and a shutdown. My last attempt was to create a USB boot drive from the original install discs, but my old Sawtooth won't let me run the installer.
Is there any hope at this point? I just bought the thing last May, so I've had it less than a year and a half. The distorted startup chime makes me think the logic board is fried and no amount of fooling with the startup drive will make a difference. The only thing out of the ordinary in this case was that it went to sleep last Thursday night with a DV camera hooked up via Firewire.
I'm not thrilled about giving Apple any more money for another Mini, but I'm heavily invested in Logic Studio so I don't have much of a choice of platform.
I'm pretty sure I'm doomed, but I thought I'd post anyway. A quick internet search shows I'm not the only one with the gray screen of death on a fairly new Mini. Thanks in advance for any pointers.

Thanks.
The Genius was able to get to the Apple logo and spinning... thing (what used to be the beachball). His theory was that as long as the Snow Leopard disc was in there, the boot process would never get to the Firewire port. Once I got home I literally pried the Snow Leopard disc out and put in the original install disc. But any progress whatsoever ends in the system bomb message.
Thing is, I had tried to eject the disc by booting with the mouse button down. But on restarting, the laser in the optical mouse flashes quickly, once. I don't think the USB ports are going "live" at all... so I can't get into single user mode, safe mode, hardware test, anything. The Genius' keyboard was no help in that regard. So yeah, I suspect a hardware problem.
A search of "gray screen of death" shows this happening to a lot of models.

Mac Mini won't boot, repeating startup chime

This afternoon I noticed that my Mac Mini (1.5 GHz Intel Core Solo) was acting sluggish. I opened up activity monitor and saw that the process 0 (kernel_task ?) was using about 50% of the CPU. Assuming that it was in the middle of something, I left it alone for another 10 minutes. Still 50% red in the CPU Usage graph in Activity Monitor. I then turned the computer off. When I turn it back on, I get a gray screen, one normal startup chime, followed by somewhat quieter startup chimes about 1 -2 seconds apart. I've tried resetting the PMU, starting up with no USB connections, safe mode, by CD, etc. I don't think the keyboard is even recognized. I know that works, because I tested it on my laptop.
Any suggestions?
Thanks!

OK, well it would not make any difference that the install disk was already inserted - as long as the Option key was being held down at the right moment, the system would go into the boot loader screen even if there were no bootable volumes.
Make sure the Option key is down immediately you hear the first chime. If you've been doing that, it would be an indication of a more serious fault.
Try an SMC reset to make sure the system hasn't just corrupted the management controller, then try again.
An SMC reset can be accomplished as follows:
-From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
-Unplug all cables from the computer, including the power cord and any display cables.
-Wait at least 15 seconds.
-Plug the power cord back in, making sure the power button is not being pressed at the time.
-Then reconnect your keyboard and mouse to the computer.
-Press the power button on the back to start up your computer.
If that doesn't work, there's a hardware fault. In which case the nature and pattern of sounds you hear after the initial chime may be the clue, since these may be the system giving an audible report from the power-on self test. Are these regularly repeating beeps? rather than chimes? If so, you should hear a pattern of 1, 2 3 or 4 of them followed by a second pause, then repeating.

No startup chime, red light, fans running loud...

yeah, I know that there are other threads with the same topic, but I just wanted to know how common this problem is?
How many people have experienced this?
What are the common disturbances?
What is going on?
Why is such an expensive, powerhouse computer become such a puny electronic product because of power issues?
I posted this in another thread but,
Here's my story:
I am having the same problem.
Now before you start taking advice to back up all your data, reformat your hard drive, and reinstall all the software; please take note of a few things:
first off, I'm ****** that this is happening to me. I spend $5000+ for a "reliable" Apple computer. Then it doesn't want to turn on because its not safe. Sorry if I drown this post with bitter sarcasm but I am coming to the end of the line with my patience.
I called Apple Care, read a bunch of posts (here and elsewhere), and yes I do know about the SMU Reset button (like that really does anything?).
My problem happened a few weeks ago and I thought nothing of it at first. There was a power outage for a quick second and it turned everything off. When I went to turn on my computer, there was no chime, the red light was on, and the fans were running and eventually began running very loud. After letting it run like that in hopes of the screen lighting up, I turned it off by holding the power button. By the way, there's nothing on the screen and the keyboard doesn't work (I use a wireless keyboard, but I plugged in the OG cord keyboard to push whatever series of buttons recommended by these "geniuses") Trust me, the computer doesn't make it to that part of the boot process, so stop with commandoption+PR or F12 to get the CD out. It doesn't work! What's up with this computer! It can handle all these intense calculations,etc. but a power surge is going to shut it down indefinitely.
So I left the computer came back the next day, turned it on and its fine. Cool, I'm happy. It's Working!! I go on a few weeks, then I go to turn it on this Monday, same problem. But actually a worse situation. I had a client come over and the computer wouldn't work. I looked like a idiot. Couldn't do anything cause my computer didn't want to turn on. I do music production/editing. I use my G5 for running ProTools LE. I have other programs but that is the main one I use. There's nothing wrong with it. It's optimized for use with the mac. So those people who are going to advise me to uninstall all my software and all that - I appreciate your concern but don't give advice when you don't know anything!
So I am getting frustrated. My client left a little disappointed, but what can you do? I tried to call AppleCare on Mon. but it was Memorial Day. So I waited for Tues.
Tues morning, my computer turns on like everything is fine.
I'm happy but cautious. I talk to AppleCare rep. He tells me that it is a common problem they have heard about with the G5's. Wherever blackouts, brownouts, spikes, sags, dips, and other electricity inconsistencies occur, the Power Mac G5 has a breaker in it which flips so it doesn't receive uneven power supply and damage internal components.
I like that feature. Good thinking Apple. Protecting my investment from bad electrical grids. But I don't like the fact my computer has a mind of its own where it decides when it wants to boot or when it wants to sit there and run its fans all loud.
I shut down Tues morn to go to work. I come back in the evening, it doesn't want to boot up. Instead of getting angry trying a bunch of times to turn on/turn off the computer, I leave my house all together and go and have a few drinks. I come home ,don't even look at my computer, and go to bed.
I wake up Wed. morning. Go to turn on my computer. Successful boot. It's running. Okay, I think, I'm going to get down to the problem. I read all the logs, not like I know every piece of info, but just to see what's happening. Everything looks fine. I decide to run the AppleCare CD Tech Tool. It says restart holding down C. I do that. When the gray Apple Logo comes up, all this writing about kernals comes up and it tells me to restart or shutdown. I shutdown and attempt to restart, same problem: no chime, red light on, and fans eventually spin loud. Now the CD is stuck in there. I'm going to take it to the Apple Store tomorrow to if these "geniuses" can figure it out.
(Just a side note: Apple calls them geniuses, but its hard for me to think some disconnected college kid with a bad haircut and questionable social skills knows what's up with the power supply issues of a computer; maybe I'm wrong, but you can run your diagnostics and look at the chart of what to do and all that BUT Apple needs to listen to the people)
I am going to get a UPS (uninteruptable power supply) with a clean sine wave output to curb the issue at my end. It's not my fault I live in a area that receives uneven power output. I live in Los Angeles. Summer is starting up and I think its going to be hot, so blackouts, power dips and sags are inevitable. I just don't understand why Apple hasn't considered this problem and fixed it with something:
A recall to change the power supply, Is it something on the logic board?, are they going to reimburse me for lost income (Ha, yeah right)
I really want to know how many people are having this problem?
From what I've heard, it is a common problem.
So I think we need a common solution.
If its so common, it must be the computer. We are all going to live in different areas where the power may vary. Not all of us have the consistent power flow of 1 Infinite Loop in Cupertino, CA. So if it is such a common problem, Apple needs to fix it.
I can't spend more than five grand on a super duper computer and have it wuss out on some power issues.
Its a loss of income and productivity to me.
I can't have that anymore.
Sometimes my computer turns on, sometimes it doesn't.
I bought my PowerMac G5 in April 2006, its been about a month and a half and I'm having these problems.
Thank you for your time.
If anyone else has been having this problem, I feel for you.
It was been very difficult for me not to curse in this post, but I have tried to extend the same respect to all that use these discussion boards to create dialogue, find help, and create solutions.
LETS FIX IT!

Well, you can see my specs below. I have the same problems as you, just worse. I am also running (as I have my previous systems) on an APC Smart-UPS 2200, and it doesn't solve this problem.
I bought my machine last December. In early March (just 2 days before my 90 days of phone support were up), I woke the computer from sleep to check email; about 5 minutes later it just froze. I had to force it down, but it never even got to the startup chime.
Called Apple, bought Apple Care on the spot, spent about 45 minutes on the phone with two levels of support, and Apple couldn't really diagnose the problem. They decided to send out a replacement logic board, processor unit and power supply for on-site service (I don't have an Apple service center nearby).
Nearly two weeks later the technician arrived with the parts, installed all of them, and - nothing. The system still exhibited the same symptoms as before the repair. He spent around five hours here, most of it on the phone with Apple. They decided that the processor unit they shipped was defective, so they sent another processor unit.
Nearly another two weeks later, the re-replacement processor unit arrived with the tech. He installed it, and everything worked. This was around April 1.
Fast forward to last Wednesday. Arrived home from work, tried to wake the Mac. Nothing happened. Had to force the machine off. Never booted again. Called Apple and went through the motions again. They're sending another logic board, processor unit, and power supply.
I asked about having the machine replaced since this will be the third repair attempt, considering it took two visits and nearly a month to repair it the first time it died. Apple was unwilling to replace it but I was told that if I had another failure, a replacement would be in the cards.
I agree with you about needing reliability in a computer as expensive as a Power Mac. It is not acceptable to have this kind of failure, repeatedly, with this kind of system. If my Windows PC has a hardware failure, I can take care of it myself. A top-end power supply is ~$200, a quality system board is ~$200-$300 - all very doable, and in very little time, if the need arises. A Power Mac logic board is ~$1K, a cpu module is well over $1K, who knows how much that crappy power supply costs, etc. If you have Apple Care, you face the kinds of downtime I'm having to deal with. A month without use of your computer. I mean, if I buy a Dell workstation, or an HP workstation, and pay an extra $200-$300 for service and something fails, Unisys will be here the next day and it will be fixed. That's the standard business class service experience you get from those companies with a computer that costs $600, much less the $3000+ you dish out for a Quad Power Mac. Apple's response is unacceptable.
It's a good thing I have kept my Windoze machine around, cause it's really saved my butt the last 2-3 months; that also makes me really sad, because in the last 6-7 years of Power Mac ownership I've had zero problems with any of them. My dad has my previous machine, a Rev A Dual 2.0 G5, and it's rock solid.
I sure hope that the Intel based Power Mac replacement doesn't suffer from what ever seems to afflict the recent Power Macs. I would absolutely hate to abandon OSX, but I will not put up with this kind of quality failure (hardware & service) again.

Re-Start Issue: Chime Echo after startup chime ??

My 20 Intel Imac running OS 10.4.9 has developed a minor problem related to its startup sequence and I suspect firmware startup instructions:
When using the control panel startup disk dialogue to reboot from Windows XP back into OS 10 I get a repeating shorter echo of the familiar startup chime and the machine will not reboot into Mac OS until I hold down the power key at the back and force it to.
Similarly, altho with less serious effect, the machine echoes its startup chime a second or two following the normal restart chime when in OS 10, but in this case it des then reboot normally.
I suspect a corruption of firmware or NVRAM but I am unable to force a reset of NVRAM by holding down COMMAND-OPTION-O-F during restart. This works on a PPC G5 but does not seem to reset NVRAM on an Intel-based Mac.
Any suggestions from the list as to the cause and fix for this strange echo of the startup chimes ??

A NVRAM or PRAM reset is accomplished with Option +  + P + R.
Startup key combinations for Intel-based Macs
The startup chime is an indication that your RAM is OK and the Mac has passed the Power On Self Test. You might try reseating the RAM modules.

I've lost some keyboard commands and can't get them reset!

I seem to lost some keyboard commands in Photoshop CC. For example... I used to be able to use the Spacebar to temporarily access the Hand Tool - no matter what tool was selected. Now it doesn't do anything. I used to be able to use "Command + Spacebar" to temporarily access the Magnify Tool. This no longer works either. I've reset Default Preferences with no luck. I've also looked through the Keyboard Shortcuts & Menus screen, but it will only let me use (or change) a single keystroke to access a tool. What happened to the ability to TEMPORARILY ACCESS specific tools? I can still use the keyboard combinations mentioned above on my computer at home, but can no longer use them on my computer at work. Does anyone have any suggestions?

You said, "I've reset Default Preferences." Are you referring to Cmd+Opt+Shift? If not, try that reset: Close Photoshop. Now press and hold Ctrl+Alt+Shift as you initiate Photoshop startup. Select "yes" when asked if you would like to reset.

Can I create a keyboard command for the Ken Burns effect?

Friends,
I am creating a short video that consists of about 40 stills and a few video clips. For each of the stills I want to create a Ken Burns effect. I know that there is a keyboard command to open the crop tool. Can I create a keyboard command that opens the Ken Burns editor? I guess the broader question is whether I can create a macro that combines a keystroke and one or more mouse clicks?
Thanks!
Steve

The Keyboard-shortcuts-editor
⌥ - ⌘ - K
doesn't list the 'Ken Burns'-effect as 'shortcutable' …
And I doubt, that even Automator
http://support.apple.com/kb/HT2488?viewlocale=en_US
would createany useful 'shortcuts':
Each picture is different - so, how should a 'standardised' KB work?
What does work indeed , is copy/paste of Attributes:
create your KB for clip#1
hit cmd-c
select clip#2 (or many) hit ⇧-⌘-V and select the 'crop' attributes ...

My keyboard commands in Adobe Illustrator aren't working after the new update

Hello,
I like many others have done the new software update for the Mac - OS X Yosemite. And theres been a few bugs I've experienced. Along with slow internet my Adobe Creative programs have been acting up.
Mainly Adobe Illustrator CS5.5 - first was the font preview playing up but have fixed that with reduce transparency option. But now and the more annoying one is keyboard command keys are not working.
Main ones I have notice so far are: Delete, Shift + Command anything, Tool Bar shortcuts i.e Selection Tool (V) etc.
Its incredibly annoying and is actually interfering with my ability to work especially the simple one of deleting. I have seen a lot questions similar but to other programs and other suite versions. Please have anyone found an solution or please Adobe gives us the key to resolve this as it is a major inconvenience and is stopping productivity.
Many Thanks
Phoebe K

Phoebe,
Item 7) in 5) (follow the link) in the general list below shows the usual suspects. You may use that to find out which to avoid.
The following is a general list of things you may try when the issue is not in a specific file (you may have tried/done some of them already); 1) and 2) are the easy ones for temporary strangenesses, and 3) and 4) are specifically aimed at possibly corrupt preferences); 5) is a list in itself, and 6) is the last resort.
If possible/applicable, you should save curent artwork first, of course.
1) Close down Illy and open again;
2) Restart the computer (you may do that up to 3 times);
3) Close down Illy and press Ctrl+Alt+Shift/Cmd+Option+Shift during startup (easy but irreversible);
4) Move the folder (follow the link with that name) with Illy closed (more tedious but also more thorough and reversible);
5) Look through and try out the relevant among the Other options (follow the link with that name, Item 7) is a list of usual suspects among other applications that may disturb and confuse Illy, Item 15) applies to CC, CS6, and maybe CS5);
Even more seriously, you may:
6) Uninstall, run the Cleaner Tool (if you have CS3/CS4/CS5/CS6/CC), and reinstall.
