PowerPC :: G3 Unable To Boot Up - Turns On But No Chime
Nov 20, 2006
Late last night, I ran into some problems with my iBook G3. It's the 700 Mhz model, with 384MB of RAM. Nothing else special in terms of hardware config (unless an Airport card is special). OS X 10.2.8.
Basically, the computer seemed to hang and I did a hard reboot, and upon starting up I got a folder with a flashing ? .
I can't seem to find my Install disc 1 to run Disk Utility or just boot up - hopefully I will find that when I go home tonight (or maybe I left it at my parent's place), but I checked using the Hardware Test CD and it didn't detect any problems.
I am having problems opening the CD drive, so I've had to open it using a paperclip. Sometimes it doesn't appear to be using the CD.
I also have run the Micromat test CD that came with Applecare (of course this machine is almost 4 years old so that's finished...) and it detected a problem with the Read Buffer last night, but then I guess the battery ran out while it was on the last test.
This morning, I ran the Read Buffer, Write Buffer, and Volume structure tests and the first two passed very fast (unlike last night), but the Volume Structure test failed. I'm not surprised since I've been aware I have issues with this before. I tried to repair before going to work but at one point it seemed to hang so I gave it another hard reboot.
Last night, I would sometimes get the apple logo with the spinning "clock", and sometimes I would get the ? but it would never get to the login screen.

So I've got a powerbook G4, thats 8 days past its warranty. Conveniently, it now won't turn on. It won't wont boot from CD. If I turn it on, I get a gray screen that usually just turns my computer back off, if thats not the case I get a screen that shows the finder icon and a question mark and then turns off.
All it will do is boot into open firmware mode. Currently the install disc is inside of it and I've tried booting the cd using "cd:, bxi" and "dir hd", and it can't open both. Does anyone know how to wipe the HD, and start the installer using firmware? Otherwise, I think I'll have to take out the harddrive and plug it into an external case and then wipe it.

I recently reinstalled a clean Tiger on my old MDD G4 with the intent on giving it to a friend of mine in Oregon. Everything was smooth here in Los Angeles. Got the OS on and running sweet... 10.4.11 combo update... all's well.
I drive up to Oregon, set it up in his office using his old CRT monitor and power it on. It chimes and manages to find the Tech Tool eDrive recovery partition, but not the OS on the boot drive. Then, seconds later, screen of death/kernel panic and no boots or startup chimes thereafter.
Steps I've taken:
I have reset the PMU
I have removed all peripherals, including viddy, SATA adapter and all but on stick of RAM
Tried every stick of RAM by itself
No startup chime -- just a fan for a few seconds then a super fan kicks in... no signal to monitor at all.
Strange symptom: at times power was making it to the drives, and other times not. (determined by me putting my hand on the drive to feel its vibration or lack thereof during boot).
Do I need a new PSU? And if so where to buy?
------------------------------
Dual 867 MDD G4
SATA adapter/w 300GB Tiger boot drive and 200GB data drive (w/ Panther still installed)
120GB data drive on IDE 66 bus w/Tech Tool recovery / restore partition

I have a lovely secondhand 12 inch Powerbook G4. It won't boot but will just chime and go to a grey screen. I can't boot to safe mode but I can get into Open Firmware I have reset PRAM and the power manager. I don't have the install CD but I borrowed one from a friend with the same model and it wouldn't boot from that.

So I was just there, using my computer, doing nothing out-of-the-ordinary. I decided to open up a program (Yahoo! Instant Messenger, I think it was) and the computer went nuts. I completely froze...nothing I tried worked. So I shut the computer down and tried rebooting it. It chimed and went to the white start-up screen with the apple...I let it sit for about ten minutes to let it restart. Still the white screen. I shut it down and tried it again. Same thing.
Is my computer dead? What might I be able to do to fix it? How much might it cost?

My 20 inch iMac (g5) won't boot.
The chime plays, screen lights up but goes dark again and nothing more happens.
I can hear that the dvd rom is powered (the little eject thingy plays as always) and the HD spins up.
So far I've reset SMU and PRAM (yes it does the rebooting and plays chime again).

I have a mid-07 Santa Rosa MBP. When I turn it on, nothing comes on the screen (not even backlight), but I'll hear the startup chime and 2 seconds later, it reboots and does the same thing. Here is what I have tried:
1. Reset SMU
2. Reset PRAM
3. Replacing HD
4. Replacing PRAM/CMOS battery
5. Tried booting off DVD (but it reboots too fast after the chime)

My mini "starts" without chime when I press the power button on the back. The fan starts, the light in front goes on and I hear some clicks which could be the hard drive. The screen remains black (no signal) and the mini does not respond to the USB keyboard power button. It does not start when pressing it and will not power down if I press it for any length of time when it is on. Pressing the power button on the back for some time shuts it down.

I am having a problem getting my G5 to boot. Half the time when I turn it on I get no chime. The other half, I get the chime but the boot process does not continue. If I leave the computer on the fans begin to progressively get faster and louder after about 5 minutes. I've tried starting with various USB and Firewire components unplugged and have even gone to just a keyboard and mouse. No change. Can I get the computer to boot from an OSX CD? How do I open the tray? etc.

Powermac G5 Dual 2.5GHz

Although this isn't a very important problem, I have noticed on my early 2K8 Mac Pro the Boot POST chime will not play through external speakers. Is there a way to enable this, as it is awfully tinny from the internal speaker.

Ive got a G4 Power Mac 2x500MHz that Im getting a bit frustrated with.
Situation:
- Power supply seems to work as power flows once I hit the power button. Fans spin, red light comes on the board, connected drives spin up, drawers open.
- No chime. At first it was sporadic, but now non-existent.
- No video output. Has the original AGP ATI 128 Rage Pro graphics card.
- No power to USB ports? Try plugging in devices that light up in USB but nothing happens.
What Ive tried:
- Ive replaced the board with a known good board and get the same results, and of course i thought this was the main problem. I did get a tiny whiff of burning smell from the previous board, though no signs of physical defect on it. No smell from the new board.
- Replaced and swapped around about 6 different ram sticks.
- Tried PCI graphics card (probably not compatible though) and no results, as expected.
- Reset PMU of course.
- Swapped processors.

A friend gave me one of these, said he didn't test it. i tested it but have observed the following: ring on PSU plug illuminates fine, was orange but now greed thus battery charges ok. battery button works too, pressing that initially showed 1 dot, now shows 4. charge ok and accepted. pressing the power button though, i hear the fan spin for 1 sec, the disk and the cd drive click in, but no chime and nothing on the display. no response nothing, a hard reset (hold power) turns it off. I did the PMU reset, and the pmu did do a reset, but nothing. I also did the PRAM, and again nothing. I am suspecting a faulty logic board, I hope i can get this going as aesthetically it's in good condition. For the info it appears to be an iBook G3 model A1007, If you need any more info then give me a shout.

The sound on my 17" G4 Powerbook does not seem to be working any longer. I know there are some similar threads but I think my problem is slightly different because I get sound on startup (the startup chime) then when Leopard loads it seems to be dead.
When I press the volume keys (F4/F5) I see the volume indicator increase/decrease but I do not hear an alert sound.
When I go into System Preferences/Sound, "Internal Speakers" is grayed out under "Sound effects" but "Internal Speakers" shows up under the Output tab.
When I plug in headphones, I get no sound.
I've tried resetting the PRAM and open firmware.
I've tried creating a new user and the new user also has no sound.
I've tried repairing permissions, running disk warrior while booted from another drive, and a disk repair in disk utility, as well as fsck-fy and also clearing the cache files with applejack.
I am runnign Leopard on this machine, version 10.5.6.
I though it was a fried/disconnected sound card or a logic board issue until I realized that the startup chime was playing just fine.
Also, whenever I press the volume keys, I get the following error in system.log

so I have a very unique, bizarre problem. A friend brought her G4 1.67gHz 15" Powerbook to the office to have it looked at as it wasn't working properly. I took a look at it and found that one of the RAM chips was shorted out. I took it out and ordered her a new pair (since it was like $26 for 2gb, and with the one removed she was running on 512). Here's where it gets bizarre: I installed the new RAM and it was freezing regularly. I then took one out and it was still freezing regularly. I booted it from my Utilities partition (I have a bootable firewire drive set up to fix problems and recover data) and ran Disk Warrior, TechTool, and a whole heapin helpin of other fixin and optimization apps. I got it to fix all the reported errors, TechTool reports no hardware errors, everything should work perfectly. So now, the laptop boots to a blue screen. I can't boot it from a retail Tiger install disc, and I can't boot it from the hard drive, it just boots to the Apple logo, the Unix spinner, and then goes blue and freezes. So I set it as a firewire target drive and was able to do an archive/install of Tiger using my G5. It recognized and installed fine and it booted my G5. Ok, so it's not the drive. I restart and nothing, apple/unix logos then blue screen. Same with the Tiger DVD. I replace the original 512MB stick (the working one) and still same result. So finally I go back to my Firewire repairs disc and everything boots fine, all tests come out fine, drive is recognized and works fine, etc. What could cause a computer to boot, a drive to be bootable, but a computer not being able to boot on any installed drive?

I have a 17" G4 1Ghz iMac, we used it until 10 months ago when I got my new 24" Intel 2GHz machine. That new 24" iMac is now in the basement craftroom as the digital hub for pictures/video/etc., while I brought the 17" G4 1Ghz iMac out from my closet for the upstairs loft general web surfing machine. It worked for 2 days and upon shut down would not re-start. I could only hear the fan and nothing else. If I held the power button for 10 seconds upon trying to start up there was a chime that sounded for a few seconds. Once the fan is making small sound, nothing else, if I hold power button for 5-20 seconds the computer will shut down (fan turn off).
Did some online checking, found article on PMU, so I did try and re-set PMU via the apple support article.Resetting the iMac (Flat Panel) Power Management Unit (PMU). Still, no re-start. It was running the latest 10.4.x update upon being put away for 10 months. Here is a picture of the bottom, the red light is on upon trying power on, my finger is on the PMU reset button. Is there any other diagnostic thing I can do? Is there a battery on this logic board that I can check/replace? I'm 100% ok at taking it apart and trying anything to fix it.

I just bought a powerbook, and I'm trying to get it to turn on. It doesn't have a hard drive, so obviously it won't be able to get it to boot. I just want to be able to get to the flashing folder. When I press the power button, the computer does nothing, not even the fan spins. The only indication I have that it is on is the caps lock light turns on. I've tried resetting the pram, but the screen stays blank and does nothing. I don't have any ram modules in it, so it shouldn't be a ram problem.

well where do i begin ?? basicly i purchased a ibook g4 14" 1.33ghz that had its harddrive upgraded by a apple service provider. About two weeks after this upgrade took place the harddrive started playing up and the machine would not see the boot volume on the drive when restarted or every now and then the machine would freeze after some time of use, a few hours maybe. i ran apple hardware test and it came back clean after zapping the pram and disk warrioring the drive it fixed this for a day then it started again oh well.
so i sent it back to the service provider who said yep its the hadrdrive goody !!! oh NO he calls back the next day and says the new harddrive is not reconized and that they tried a new ribbon cable WTF when i sent it in the machine saw the harddrive via target disk mode all the time it just didnt see the boot volume.
NOW his saying its the logicboard **** sake !!! so my question could this machines logicboard be fried when it was fine before i sent it in , i mean the ide controller was fine i checked it and now im faced with a brick !!!what do i do ????

I have a 13-inch, Mid-2010 MacBook Pro running OS X Mavericks. I was using it near a bathtub, when a moderate amount of water spilled onto the keyboard. I immediately dabbed out most of it, and put it upside down for some time. It was running then, with all the keys and trackpad working fine. t turned it off, and tired turning it on after half an hour. Nothing. I decided to keep it switched off for 7 days, during which I would open the lid every now and then to find vapor on the screen from the keyboard which I would wipe and close again.
I turned it on when there was no vapor spotted for 3 days. I plugged it in after 7 days, to see that the battery status indicator was erratic. It turned on with a sound from the SuperDrive (the usual click). There was no startup chime. A few minutes later, it turned off. I decided to reset the PRAM and SMC, and I realized that I can get to my account window successfully (and type a 22 letter password) as long as I keep any key pressed throughout bootup (option, command key, etc). I have tried many times, but it just turns off with a "nik" sound. I haven't backed up, and I have about 270 GB of important data stored that I CANNOT lose.
It's 250GB drive crashed in December but it was replaced with a 500 GB and has been running smooth until this.

It made a loud (very loud) beep, while the screen was grey. The power button flashed in yellow, and then became orange, and then chimed like it usually does, and booted normally.
Now she is using it, it's like if nothing happened.

A couple of weeks ago, out of the blue, my Ibook 12" started turning off by itself.
At first it would turn on again, I was able to check the HD with the Disk Utility, which reported a fault in the HD. Then after a few times it wouldn't turn on anymore. I couldn't hear the chimes sound and the fan (or HD) would start running pretty fast.

Thought it would be fun to troubleshoot it, since I already own one and have taken it apart.
Here's what's wrong with it.
I've gotten it to boot up. Curiously, it describes itself as a powerbook!?

I've a MDD G4 dual 1.0 along with the wide acrylic-bezel 20" Mac monitor with the light in the lower right corner. Yep, it's starting to look ancient. But I still have much use for it EXCEPT that it has a very nasty habit of turning itself off catastropically in mid-thought, as it were. Oddly, this behavior comes and goes in spurts. it will hit hard for a couple of weeks then a couple of months will pass with relative peace and stability. Then, back to the crisis.
Sometimes I get a warning from that power-on light in the bezel -- it might flash brighter for an instant, then within a few seconds the whole system loses power just as if I'd turned off my power strip. Other times, it pops in and out of sleep mode for several cycles, but usually this ends the same, with no power at all. Odder still, the machine has a tendency to turn itself on unaided. This can happen even after a controlled shutdown. It turns on, acts normal for 20 minutes, then maybe goes to sleep and wakes up a couple of times, then crashes. No intervention at all on my part at any time. This is not a software shutdown of any controlled variety. Anyone know what's happening? I can't tell you how much gnashing my teeth have endured.

My co-worker needs help with his iBook.
I switched when the Mac Mini came out, so seeing this iBook from 2001 is pretty interesting.
Anyways, he's having problems with the LCD that when he opens it all the way the LCD turns off. Any ideas for DIY fix? He also wants to know if he can add Wi-Fi?
