NCQ on iMac G5 (non-iSight)

Anybody know whether or not iMac G5 1.8GHz (non-iSight) has Native Command Queing (NCQ) support on the SATA bus?

The hard drive may be new, but it can also be failing, clicking is the death rattle of a bad drive. However, perhaps you might like to open the back and check the fans, see whether they turn easily and are free of dust. At the same time, check the caps, both on the logic board and in the power supply, to see if they are bulging or leaking.
Also, check the [LEDs|http://support.apple.com/kb/HT2831] and run Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk.
When you reboot from your internal drive, run Permissions Repair from the internal Disk Utility.
Please let us know how thing went,

IMac G5 non-isight shutting off randomly

My iMac g5 keeps shutting off randomly during use. I have a niMac G5, non-isight and it stays on for 30 mins, an hour, or 3 hours and then shuts off as if someone is pulling the power cord out.
Upon starting up, sometimes it doesn't make it to the login screen before shutting down again. It runs normal for a while, then it would randomly turn off. I have downloaded heat temp monitor programs and it seems to get to about 70 degrees celcius sometimes. Upon restarting, I get the "report problem to apple" screen with this information. I have tried to restart the power supply too.

The problem is a thermal one, somehow there's a malfunction and the computer shuts down because it's overheating. You should take it in and have the power supply looked at. You can also take the bgack off and check the capacitors to see if any of them is swollen or leaking.
Let us know how you make out,

IMac G5 non-isight Hard Drive dead - 2 questions

1. I see that 1TB drives are very affordable but is there one that is going to be better than others in my 5 year old iMac G5? Hitachi, Seagate, WD, Samsung, etc..
2. Is there only one HD bay? I want to leave the original in just in case it can be accessed later (Apple Store tech could not read it and pronounced it dead). I would like to install the new one as an addition so is there more than one hard drive bay?
Thanks!

There is only one bay in the iMacs, and any of the brands you mentioned would be good, look in macsales.com or newegg.com for drives. I'm afraid you will have to take the old drive out, but you can always put it into an enclosure if you think it's useable. You can get enclosures at the places I mentioned.

Please HELP iMac 17" (non isight)

Keeps freezing up. Haven't done anything different today than any other day. Came home from work, wanted to check email. Froze right on the spot, dashboard, nothing responds, shut off several times with power button. Just replaced this hard drive no more than 8 months ago.
I tried, that one trick where you disconnet everything, wait a minute, hold the power down until a weird "ding" sound. That tends to get it passed the opening where everything loads, then I'll check mail & dashboard freezes in mid animation!
What's going on?

Does it boot from the install DVD?

Screen Problems with iMac G5 20" (iSight)

Hello!
I had the same problem with my iMac G5 20" (iSight) as described by Bob North Apr. 18, 2006 at http://www.macintouch.com/readerreports/imacg5/topic2276.html#apr25:
"""" I repair Apple products, and recently I've seen strange and erratic display problems with the G5 flat-panel (iSight) 17" and 20"...and I am very curious about the origin.

Upon boot, the dispaly appears normal, but within 5-10 minutes, either at desktop or in ASD, the normal display will "crash" to the "plaid" display. The desktop, or whatever, can still be distinguished in the background, but it is overwashed by the plaid patterns -- which do change slightly, and also cover the full space of the screen.

I can't use the mouse or anything else, and after a while the fans start to go on max. This is the second time I encounter this problem within 30 days. What I have noticed is that the day before, the brightness of the screen started to "blink" slightly -- like if the screen tried to adjust itself.
But I haven't experienced what Bob North describes as the: "Upon boot, the dispaly appears normal, but within 5-10 minutes, either at desktop or in ASD, the normal display will "crash" to the "plaid" display".
I just restart with the power button and everything is working OK. I made an Extended Hardware test without any problems detected.

Does it look anything like this?

My nearly 3 year old Titanium PowerBook G4 just did this one day, out of the blue. The problem went away after a few minutes, but I had already taken photos. Thanks to those photos, Apple gave the powerbook a new logic board.
(This PowerBook has had its logic board replaced twice, a new optical drive, and a cracked case edge replaced. AppleCare has more than paid for itself. Despite the occasional problems, I remain very happy with this machine. I'm sure I'd be much less happy if I had not bought AppleCare!)

I have recently upgraded my iMac Intel G5 iSight to OS 10.6.8 and now the internal mic does not work with skype or facebook. I can here static when playing back clips. Do I need to update firmware or reload old sys parts

I have recently upgraded my iMac Intel G5 iSight (iMac5,1) to OS 10.6.8 and now the internal mic does not work with skype or facebook. I can here static when playing back clips. Do I need to update firmware or reload old system parts. I have zapped PRAM. The blue indicator in system audio panel will appear for a second as I slide the bar for internal mic but then it disappears. Is there a fix?

The sound seems very faint but can here static on playback.

Ipod Classic 160 6th g. doesn't sync w/Imac g5 non intel OS 10.4.11. This is a replacement for same ipod which was stolen recently. That pod worked fine with Itunes 9! Now this pod says it only works with Itunes 10.7. ***!!!! Why has Apple screwed up?

My ipod classic 160 6th gen. was recently stolen. It had 3000 tunes on it and it synced perfectly with Itunes 9 on my Imac G5 non intel OS 10.4.11. So I recently bought same model and guess what, it doesn't sync at all. Now message says it only works with Itunes 10.7 and up. I certainly cant afford to buy a new intel based Mac and I really dont need a new pc. It feels like Apple has dropped the ball on its long time users and tough luck to you and all the $$$$$$$ spent on downloading songs and buying ipods over the years! I AM SO ANGRY THAT I CANNOT BRING MY MUSIC WITH ME ANYMORE. I dont know if there is any solution to this except being extorted to upgrade to new tech! I have been trying to get answers to this issue but nothing seems to work. Any help would be greatly appreciated. I am not a tech genius so extremely techy solutions will be in vane.

one more detail, after a restore, when I attempt to reload music to the ipod, if I try and move, say, 20 files, the transfer seems to work as it should but then stalls on the last file. Eventually, the status will change to "Updates Files on (my ipod)" a and suggests the iPod is syncing even though I have the auto sync feature turned off.
This process eventually works itself out, and seems to take longer relative to the number of files I attempt to transfer. Once done, howver, if I try and eject and dismount the iPod, iTunes stalls with the spinning pinwheel and I am warned that the iPod is syncing again with the spinning candy cane status bar. Eventually thisd works itself out and the iPod dismounts from iTunes and the desktop and eventually the iPod is free to disconnect.
Then if I try and play the music I just transfered, the iPod says there is no music loaded.
Ideas?

IMac G5 (no isight) power supply keeps failing

I had some trouble with my iMac G5 (no iSight) about 5 months ago with the power supply. I replaced the power supply, worked great for 5 months and now it's doing the same thing (turning off suddenly, trouble rebooting). I've done all the resetting of PRAM, NVRAM and SMU. Wouldn't start at all (white light would just flash) until I reset the SMU again. Didn't see any leaking items inside the machine like I've read about. I'm curious if anyone knows if I'll have to keep replacing the power supply every 5 or 6 months?? Could there be something else wrong? Thanks a ton.
RG

Did you replace the power supply yourself, or did you do it under Apple's Repair extension programs? You may still be eligible for free repairs if your serial number is correct.
In addition to a power supply problem, you could have dried thermal paste or a bad connection which would cause the same symptoms.

Graphics problem on iMac G5 w/ iSight.

I just tried installing a 1GB RAM stick in a 17" iMac G5 (iSight). The machine has 512MB of RAM (the standard), and a 1.9Ghz processor. It is running Mac OS X 10.5.7.
My friend, who owns the iMac told me she'd been seeing some weird graphics artefacts and had been having several lock-ups on the computer which required a forced restart to fix. I didn't know what to make of this and said I'd check it out when I went to install the RAM for them.
The problem alarmed me - rather than a few stray black lines that I had been told about, I found all of the following issues.
1. Black / White or Transparent lines on windows and toolbars. These were particularly predominant on menus and other semi-transparent parts of the screen, but also occurred on solid windows - such as Safari.
2. Blank screen - the screen would just go blank after a few moments.
3. Screen freezes - everything on screen would stop other than the arrow. Sometimes this would stick as an arrow, or sometimes as a beachball.
4. A really strange phenomena when I opened a browser page and suddenly the left of the screen slowly faded to black, while the right went white. This went in increments as I watched with the image of the desktop distorted behind it, burning out.
To try to fix the problem I took the following steps:
1. Reinstalled Mac OS X 10.5.7 Combo Update. This had no effect.
2. Repaired permissions. (I didn't expect that to help anyway)
3. Tried booting into a second user account on the computer (again, all the same problems were there - even worse on the other account in fact.
4. Unplugged all peripherals (no effect)
5. Removed the 1GB memory stick I had just installed - this appeared to fix the issue and I thought that maybe this was causing it. However, after a few minutes of normal operations, the problems all came back.
Just to clarify - the problems apparently started a week or so ago (this might coincide with the owner installing Mac OS X 10.5.7, but I can't be sure), at this point the computer only had its built-in 512MB RAM. With the additional 1GB RAM that I installed, the problems seemed to be worse. I know there is nothing wrong with the RAM as I had been using it in my iMac G5 up until this point.
I initially suspected the problem was the graphics drivers - as the problem occurred after upgrading to OS X 10.5.7, though I wondered if the problem could be the GPU itself?
However, I am now wondering if it's a RAM issue as additional RAM makes the problem worse - would having more in the computer change the way that the internal RAM is being accessed and mean that the end addresses of the built-in RAM are being accessed more quickly when additional memory is installed?
I was unable to find out if the machine would work alright if booting from the Leopard or original install Tiger DVD - as I didn't have time to check these.
Please advise me what I can do to diagnose the problem further, or what the owner can do to fix the problem.

"I will have to dig out my copy of Leopard or the original installer for my iMac G5 (w/iSight) as the owner doesn't know where her copies have gone! Maybe trying these will help find a solution"

IMac G5 w/iSight With A Weird Circle

I'm having an odd problem with my 20" iMac. I bought a new HDD and I'm not able to get to the desktop so I can install it.
It seems I've tried everything but so far nothing works.
Here's the problem:
no matter what key I hold down, or whether I have the HDD installed internally or externally, it starts right up and goes to the apple and spinning gear.
I'm using the correct start up disk for the iMac BTW. Anyway just when I think, all right here we go, I see a circle with a line through it where the apple was and I'm stuck.
There gear keeps spinning but nothing else happens and I have to shut it down. I've tried resetting the pram and using the option key key, which clearly shows the install disk which I choose, but again after a few seconds I get the circle with the line through it.
Do any of you have any ideas? Thank you!

Let us know how things turn out, and also, please put your model iMac (e.g. iSight) in your specs that appear at the bottom of your post, it makes things easier and helps us to make model appropriate suggestions.

any ideas what do you think thanks for help.

If the seller proclaimed that he/she was selling a working computer, strongly suggest that you get your money back. You don't know what could be wrong nor the real condition of the computer.
Macs are not suppose to be sold w/o the system DVDs that originally came w/the computer. You will need to obtain them from the seller. System DVDs are machine specific and cannot be used from one computer to another. You also need them for troubleshooting as one of them comes w/the Hardware Test.

IMac 17" with isight RAM question

I want to expant RAM on my old iMac - iMac 17" with iSight, 1.9 GHz, introduced october 2005
Is this RAM module going to be compatible?
DDR2
*2 GB*
*533 MHz*
PC4300
1,8V
*240 pins*
*Cas Latency: 4*
My concern is if the certificate (PC4300) is going to be compatible. Apple website says that there should be certificate PC2 4200.
Thank you for your answer. Greeting from Czech Republic.

Welcome to Discussions - the specs for your memory are
iSight:
1. PC2-4200
2. unbuffered
3. nonparity
4. 240-pin
5. 533 MHz
but I think the 4300 would work, just make sure that you can return it if it doesn't and that you get a lifetime guarantee.

IMac G5 17" iSight display problem

Hi - I have an iMac G5 17" iSight. Specs are 1.5 Ghz G5, 2.5 GB RAM, 150 GB Hard Drive and SuperDrive. The Hard Drive is wiped clean, I boot it with an external FW drive running 10.5.7.
Here are the issues: As soon as the machine boots, the LCD shows 3 permanent vertical lines on the screen. This is as soon as it displays anything, from the initial Apple logo all the way until shutdown. While it is on and booted up to the desktop, it runs fine, except sometimes it will randomly refresh the screen or change resolutions. These are the only issues.
While I am quite sure it is one of three things (inverter, video cable or LCD), I still took the typical troubleshooting approach and tried any quick fixes I could. These included-
1. Boot off of known good OS
2. PRAM Reset
3. SMU Reset
4. Reseat RAM
All of these had no effect. From there I tried two more things-
1. External display via mini VGA
2. Ran Apple Hardware Test
3. Ran LCD tester
The external display worked perfectly, which tells me that it isn't the GPU/logic board. I ran AHT and the logic board passed both quick and extended tests. During the extended test I got an error for the ATA bus/drive, but I haven't looked up the error code yet. Everything passed in the quick test. I used the LCD tester, which puts solid colors on the screen (Red, Green, Blue, White, Black). The 3 lines run across the whole screen vertically, and cannot be seen on a solid white screen. On the solid black screen they show up yellow and purple.
Here is a screen shot showing the three vertical lines-
http://i3.photobucket.com/albums/y93/thisismymind/untitled.jpg
I was wondering if there is an easy way to diagnose this just by looking at it. I was figuring replacing the inverter and/or the video ribbon cable first before replacing the LCD... but if anyone here can diagnose it easily than that may save some time.
Thanks in advance!

Imac G5 (pre isight). Mass Storage Error

I have an imac G5 (pre-isight). Using Tiger. Recently it has been playing up. Two main problems: starting up and waking after sleep mode.
*Starting up issues*
There doesnt seem to be a consistent problem here. Sometimes it hangs on the grey apple screen, sometimes grey probitory sign screen. Sometimes it hangs on a black screen with white writing. On about the 10th to 20th time of rebooting, it seems to startup and work fine.
*Sleep issues*
If I leave the computer to go into sleep mode, it tends to freeze in whatever application is open. Especially Safari.
I have tried numerous fixes. I've reset PRAM, done the SMU thing. Repaired and verified disk many times. Repaired and verified permissions. I've archived and installed and archived and erased. There's barely any software on here apart from the operating software and MS Office (legal). I'm using an apple keyboard (wired) and a wired mouse. There's no important info on here so am happy to wipe everything.
Finally i did a hardware test and received a "mass storage error" (only appeared for the extended test)...
2STF/8/3: S-ATA Bus 0 –Master
Having looked up several forums i replaced the hard drive. (Made sure it was compatible, similar size and same specs as original). Reinstalled software and got all the latest updates. Seemed to be working quite well for a day or so, although there was a few 'permissions' error which seemed easily fixed.
Today i awoke the imac and it had frozen. Back to it's old tricks. Tried restarting and got grey screens, black screens etc. Repaired permissions. Ran another hardware test and getting the same error message about mass storage!
So if it's not the hard drive, what's wrong for my imac? Is it time to just dispose it?
Thanks in advance for any ideas you may have.

The recall ended many moons ago, and it's a capacitor problem, they all need replacing, those in the power supply as well, probably.
If you are handy with a soldering gun, have steady hands and are good at repairing electronics, you can do it yourself. Look at [welovemacs.com] or [synaptech.com] for parts and advice.

IMac G5 17" iSight No keyboard/mouse

I have a 17" iMac G5 w/ iSight (1.9Ghz). It boots up but loses the ability to power the keyboard and mouse at log in. Actually, I can get the mouse to light up if I plug it directly into the computer, but no control of the cursor.
Any suggestions or advice? Thanks in advance.

Two things, first, reset the SMU and then, if you can connect to the keyboard, reset the PRAM.
If that doesn't work try using Target Disk Mode to run Disk Utility and repair the drive. Try to borrow another keyboard and mouse and see if they work, also, try logging in on another account and see if you can work that way.
Please let us know how things work out,
