PowerPC :: IMac G3 (slot Loader) Buzzing / What Part
Jan 22, 2008
I bought a second hand iMac G3 off eBay for a pretty good deal, and am trying to figure out where the buzzing is coming from.
It doesn't come with any CDs so I don't think I can do a hard wear test, but I've noticed it is happening even when the display is off, and is in sleep (although it gets less audible in sleep).
Another thing I noticed is that in OS X it will stop after a while of not using it, despite the screen being on and still showing the image, is this the hard drive stopping? When I go and touch a key or move the mouse it starts again.

First and foremost I should tell you that I am a new convert from Windows.
I'm currently running OS X 10.3 and find that I can not read any of my DVD+R discs but I can read my CDRs just fine. My guess is that the optical drive is simply too old to recognize the DVD+R format. Is this correct?
My alternative to this would be to purchase a firewire external drive enclosure and put one of my newer dvd burners in it, but would I be able to boot from this type of connection or do I have to actually buy a "superdrive"?

Until yesterday, my iMac G3 slot is working fine, but today, I can't power it up. When I press the power button, the light just flash and then went off. I've opened it up to check the PRAM batt and also checked if there are any shorts on the logic board. All looked ok to me. The HDD is working fine and I supposed the power supply unit is fine too.

What is the size of the drive is it 9.5mm or 12.7mm?
And will this work?

I know it doesn't say it is compatible but it is a slot loading drive compatible with osx.

I just restored an old 1999 G3 iMac DV 400MHZ with slot-drive from the dead, and I feel it lacks a bit of power under it's hood. I already put RAM and HDD but the computing power is just not enough. What I want to do is go into OpenFirmware and speed up the cpu and possibly the bus, I remember doing so on my sawtooth but I can't find the code plus that was a G4 and now I have a G3. I also found this page [URL] that shows how to mechanicaly overclock up to 1GHZ but I want to be able to do it non physical if possible. I know this isn't the hot topic now a days but maybe some of you will remember what they used to do and feel some nostalgia(is that a propper word?).

I have a charcoal iMac DV SE 500 which won't complete a proper start. The machine chimes and begins to start, and then clicks off again before anything can show on the screen. It won't start in Target Disk mode, and zapping the PRAM (starting with alt/apple/P/R, right?) has no effect. Does this sound like a dead PRAM battery, a dead 'Power/Analog' board, or a dead hard drive? Can anyone give me an idea of how much it would cost to fix, and recommend good, reliable, cheap UK repairers It's not worth much, but I have a friend who'd love it if it can be restored to life, and I'd like to get some of the files off it if it's not the drive.

I have currently acquired a few old Macs. I have got an iMac G3 SE with a slot loading drive. The computer is fine all barr the slot load drive - it has died. I have also got a PPC Mac Mini with a suggested logic board failure.
Does anybody think there is a chance i could replace the broken slot load drive in the iMac with the working one from the mac mini? i don't want to start opening the iMac up if someone already knows theres no chance it would work.

I'm having some more issues with my cousin's iBook I'm trying to fix.First of all, it's running on Panther (10.3.9)So here are both my problems:- Here and there, the laptop makes this loud buzzing noise... it's like you are holding down the enter key somewhere you can't enter anything. It's not a GSM buzz or anything, but I don't know how to get rid of it. I've tried doing a couple of things, but it hasn't worked. Any ideas?- Secondly, I'm having some trouble with the mouse often. (I unchecked ignore accidental trackpad click).

I have had this quad g5 (dualcore 2.5ghz X 2) laying around for about a year that I purchased for $100 without a hard drive, super drive or a power cord. I was told that it was non working in the manner that ONE of the dual core cpu's had gone bad. I will be receiving my power cord this week to make sure that it still powers on but what the problem is.
My question is: If only one of the cpu's are bad, what is the part number I will be looking at? I am not wanting to spend a fortune on this to fix it, but If I do get it working I would like to drop 8-16gb ram in it, and setup a raid with 2 raptors.

My powerbook G4 aluminum was dropped about 18 inches. The display is now hosed. Thus far I have found *nothing* wrong with the laptop except for the internal display only shows gray horizontal lines with black snow/static intermixed (still in horizontal lines).
What I'm thinking is that the display is probably actually fine and there is some little logic board in the display casing that is bad.
Here is what I've proven:
1. external monitor still works fine (means vid card is fine?)
2. swapped internal displays with another powerbook and was fully functional (means it's something in my display casing or my display itself)
3. backlight works fine (on my munged display)
4. i can see movement in the grayness when i move the mouse pointer around almost like the pointer was as wide as the screen and 90% translucent (i.e. there is a horizontal shaded bar i can move up and down with the trackpad)
I've already thought about upgrading to the 1440x960 display and being done with it. But then I started thinking it is probably a $40-50 part if I could just narrow it down.... And that would be the smart thing, rather than spending $300+

I've got a powermac G5 dual 2ghz and 3 gigs of RAM that has a dead logic board. I don't really want to pay the $900 to have it replaced, so I'm thinking about just parting out the rest of the machine.

I have an older 15" powerbook Titanium. About five years old now. Been working pretty well all five years, save for an external hinge I had to replace. Last night, the computer started buzzing from the insides, a buzzing reminiscent of a distant chainsaw. The program i was working in (firefox) just went to the pinwheel of doom and never recovered. I moved to the finder, which did the same. I forced booted. Same noise. Same problems. I can use programs for a few minutes, but then they pinwheel of doom and the computer freezes out.

I came across a powerbook g4 (dvi, 15 inches, 800mhz, 512mbs, airport card, dvd-rom + cd-rw, after market battery never used and after market ac adapter)) sold "as is" on craig's list. I picked it up for $50. It had everything but the hdd. The first time i plugged it (without hdd) I got the flashing ?. I swapped in another hdd and all I would would get the apple chime followed three soft beeps (nothing on the screen). And then eventually, I would power it on and the only sign of life I would get is the caps lock light on, and the num lock light only if I hit F5 (again nothing on the screen). If i let the powerbook sit without the battery for a while, then I would get the apple chime again but then the power cut out right away. This happens with the adaptor or the battery only which leads me to believe it's not the dc-in board. I have tried different ram, disconnected the airport card, disconnected the cd player. I have tried resetting the PMU and every key combination to reset the PRAM (it never seemed to make a difference).

I have recently bought a new i7 27" imac and when the imac goes to slep it seems to crackle/buzz very very faintly.
I phoned apple who told me to do the following:
Turn off the imac.
Hold down ALT, CMD, and R, and then hold the power button.
Then still holding ALT, CMD, and R press the P key.

I've owned my iMac for a little over a year and I started having a weird buzzing noise coming from a hard drive fan. Downloaded iStat, everything runs at idle speeds (hard drive fan at 1200rpm), so the speed is not an issue. Sounds like a mechanical problem. Also downloaded FanControl, and once I increase the fan's speed to 2500rpm, the buzzing noise goes away, but now I can hear the fan It kind of defeats the purpose of having the expensive computer, that used to be virtually silent. I am in remote location in Alaska, where we don't have Apple store and the only way to fix is to ship it to mainland. Apple warranty is over, but I still get additional 1 year of coverage from Amex credit card, but I would much rather prefer to to fix it myself. Any suggestions on possibly replacing the fan myself? I am really debating whether I should ship it to Apple and trying to go through American Express with warranty. That would be complicated and I would end up without a computer for a few weeks.
Late 2008 iMac 24'. 3.06 GHz, 2GB RAM, 500GB Hard Drive, NVidia GeForce 8800GS.

How common is this? I prefer darker backgrounds and this may be an issue.I'm over the yellow and the buzzing, but this too? Don't take me the wrong way - I love my Macs but I can't say I'm crazy about this..See attachment. Ignore the image noise, the big spot that bothers me is on the top to the right.

I just got a G5 power mac (dual 2.3GHz) and bought one of these: [URL] as an airport substitute. When trying to install the card it doesn't appear to fit in the PCI slot. Am I right in thinking it should fit? Since it's a PCI card and the G5 has PCI/PCI-X inputs?

The Graphite 733mhz PM G4 has only 3 ram slots. But the "fourth" one shows up on my system as "empty". Does this mean that it may be physically possible to put another ram slot in there? I'm confused by the limitation -- though I heard that Mac OS9 could only recognize up to 1.5gbs of ram.

Initially it would intermittently not recognize the RAM that was in the 2nd slot (not the on-board ram). Now it does not recognize the 2nd RAM slot at all. I know it's not the stick, as we've put different sticks in to test.

I have a 12" PB and latelly became a nightmare with the stuck CDs. Usually it does not want to eject CDs/DVDs from companies but it handles fine virging cds/dvds. ?? Probably there is some formating in the industrial kind of CDs outside, who knows.just want to open this thread for people with the same problem.If the drive tries to eject but can't and end up mounting the CD again. Just take another CD and when you press eject again push that CD into the slot but just one third and you will see the stuck CD coming out with no problem as well.It seems there is a sensor or something that obviously does not work well. I inserted a virgin CD and the drive worked just fine and ejected later on, but a CD as the installer for my Linksys get stuck and some other softwares too.

I have a g4 slot loading drive and I am fulling aware the outside casing would be wrong... but that isn't much of an issue, I can replace the panel/casing section with a new panel to take care of that... i just want to know if it is possible as far as hookups etc are concerned.

I have a Powerbook G4 that I wanted to upgrade to 1.5G from 512MB. So I added Corsair 1GB DDR RAM to the notebook and it seems to have issues recognizing both at the the same time. When I put both of them in together, it never seems to recognize the bottom slot. Putting in the 512MB in the bottom w/o the 1GB the Powerbook boots up fine. Putting in the 1GB by itself and it gives beeping noises on bootup, but it'll boot up if I put it on the top slot.

My TiBook 15" G4 (OSX 10.4.8) has an Airport slot but no Airport card. I got a Sonnet Aria Extreme card but it shows nothing on the TiBook � not in the menu bar or in System Profiler. I've tried restarting with and without the card inserted. The Sonnet support guy suggested everything I had already done and then came up with "Check under the keyboard to be sure the cardbus connection was intact." Seems fine. I'm assuming the card has the Broadcom chipset because they swear it works fine on the 15" TiBook G4.
Also, Airport software is updated, but doesn't show or function because it doesn't see any wireless capability.
Like everybody else who gets frustrated, I've also done everything again 4-5 times, just in case the computer or the card might forget that it doesn't work.
