PowerPC :: IBook G4 Turns Off Automatically?
Jan 6, 2011Thought 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!?
PowerBook :: G4 Turns Itself Off Automatically
Jun 19, 2014I found a PowerBook G4 in my closet, so I turned it on and was using it just fine, and then without warning it turned itself off. When I boot it up I can hear an internal fan running, and it keeps running the entire time the computer is turned on. I'm not sure which OS it's running. Do I need to replace the fan, or is it something worse?

Sep 30, 2010I have my MacBook hooked up to a pair of external speakers (M-Audio AV40, for those interested) and I can hear a slight click when the computer hasn't played any sounds for a certain amount time (about 30s to a minute). My PowerBook G4 never did this, so it's not the speakers.

Sep 7, 2014My 2011 MacBook Pro screen broke so it is now half a laptop and the battery was also removed. Whenever I plug it in, the light on the front starts flashing and then it turns on. Sometimes it shuts off before the chime plays. I was using it today for about 30 minutes, and then the power button menu appears in the screen (sleep/shutdown/restart options menu) and then a few seconds later it shuts off completely without me touching it. After that I started it back up, and when it got to the desktop, and then it turned off without no warning at all (the power options didn't even show up).
I already tried resetting the SMC and PRAM/NVRAM and it seems like that didn't work.

Aug 25, 2006A 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.
PowerPC :: G4 Turns Itself Off / Shuts Down Unexpectedly
Sep 23, 2008I'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.
PowerPC :: G3 Unable To Boot Up - Turns On But No Chime
Nov 20, 2006Late 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.
PowerPC :: IBook LCD Turns Off When Fully Open?
Oct 5, 2009My 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?
PowerPC :: Powerbook G4 Turns Off / Battery Charger Is Unplugged
Jun 20, 2005My Powerbook G4 only turns on if the battery charger is plugged in, and if I unplug it, the computer shuts off. On the menu bar, it says charging. I know the battery has to be full. This just started happening last night. Also, I just had the hard drive replaced and I've only had it back for a couple weeks.

Nov 24, 2006I have a little problem with my last generation 12" Powerbook G4. Sometimes, after I wake it up from sleep mode, the screen has a kind of blue tinge to it, as if there was some blue transparent plastic stuck to it. After I reboot, it's just fine.
View 1 Replies View RelatedPowerPC :: IBook G4 Shuts Down When Power Cord Turns Red In Color
Jan 11, 2010My iBook G4 crashed on me one night, and the only way I could turn it on again was to unplug the power cord from my computer, turn it over, remove the battery, put the battery back in, plug the cord back into the computer, hold down the start button, and it would restart. Although, when it restarted, the fan would go on first, and then the computer would make the normal start sound. Some times the finder would be on the screen after I restarted it displaying a quick link icon of the hard drive. So after a few weeks, it did it again, then a few days, and then it got to the point where I had to keep my computer in the same position otherwise it might shut down.
Now, if the power cord is green everything is fine, but if I move my computer and bump the cord into the wrong place it turns from green to bright red, makes an evil buzzing sound, and in three seconds the computer shuts off and I have to restart by using the method above. If or when the power cord goes bright red I do have 3 seconds to pull out the cord before it shuts down. I then sleep the computer, put the cord back into the computer, and move the cord around until it is green again.
I took my computer to a mac genius, and when he looked at the crash report he said it was frequent, but not caused by the battery and couldn't tell me what was the exact problem. I bought a brand new power cord, but I still couldn't move the computer around to much or it would shut down.
1.) Has anyone ever heard of this happening? And if so, what causes it to be so touchy?
2.) What can I do to fix it myself?
3.) If I send it in, will they be able to fix it so that it is perfect again without having to spend more than the money assessed?
I would like to try to have it fixed. At this juncture, my only option is to send it in for $280 and hope they can fix the problem that no one seems to know what is the exact problem, or even where the problem stems from. I should add here that the battery is fully charged, and the report says it can hold about 1 hour of life, although it's more like 30 minutes, and then without warning to plug in or risk shutting down (like it used to give me) it will shut down.
PowerPC :: Unable To Boot Powerbook / Gray Screen Turns Computer Back Off
Nov 1, 2006So 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.
PowerPC :: Turns Itself Off - Emits High Pitch Squeal From Machine While Holding Button
Sep 28, 2009When I turn it on it runs fine for sometimes about a minute (sometimes less) before it just turns itself off! After it turns itself off I'll hit the power button and it emits a high pitch squeal from the machine whilst holding the button. If I then remove the battery from the Machine depending on how long I leave the battery out and put it back in, it will then power up for a short amount of time. Sometimes I can get it to the desktop and open System Profiler for example, other times it gets as far as the Apple grey screen. I've ordered a power adaptor as I didn't get one with the machine but as far as the battery indicator goes, it's on 96% and all four green lights are on the battery indicator on the base. Has anyone heard of any problems like this before?I believe it's running a 500mhz processor and has 512mb of Ram.

27' IMac (2011) Screen Turns Off
Jun 27, 2012This has been going on for me for the past few months on and off, it just randomly switches the screen off but everything else works perfectly, for example if im watching a video on hulu i can still hear the sound, if im doing work on word the documents are still there, iv finally gotten video footage of it. url...To turn it back on i press "ctrl + shift + eject" and then move the mouse. i have contacted Apple support on the phone they did say bring it in, just need to make an appointment. If anyone else has this problem and knows a better solution than having to keep pressing buttons to turn the screen back on please share.

IMac :: Screen Turns Solid Colors And Freezes?
Sep 28, 2009I have a 3.06 GHz, 4 GB, iMac running 10.6.1. and I have a weird problem: while I was running Windows 7 under Boot Camp, during a simple task, my screen suddenly turned a solid shade of gray. Having no other option, I held the power button, turned off the computer, and turned it back on.
When I booted back to OS X, it happened again immediately upon opening iTunes. This time the color was solid black. Concerned, I turned off the computer, waited a moment and booted it back up in Safe Mode, where I currently have no problems whatsoever. From Safe Mode I repaired my disk permissions, cleared my caches, and zapped the PRAM while restarting my computer back into normal mode. Unfortunately the problem persists, this time my screen turning a solid shade of dark purple.
I'm going to call Apple Care in the morning, but has anyone heard of an issue like this? I searched the forums for a solution, but wasn't sure what terms to search for.
Software :: IMac Turns On And Suck At Apple Logo Screen
Jul 17, 2010Came home from work the other day and my iMac (20" iMac from '07 / Snow Leopard) was frozen, did a hard restart and it booted up fine without much of a problem. Everything was running very sluggish so I began to verify the disc through utilities at which point it froze again, now whenever I restart I get stuck at a white screen with apple logo and something spinning underneath it. The longest I've let it sit at that screen is about an hour or so, it gets extremely hot though so I'm hesitant to leave it any longer.
I've tried a few suggestions already, safe mode with no luck, disc target onto my macbook with no luck and I've tried "/sbin/fsck/ -fy" at the command prompt which returns something along the lines of Harddrive can not be repaired. The most important thing to me right now is being able to access some of the files on there if it is not a total loss. I've back up about 2 months ago, so it wont be a total loss, but like I said, would prefer to salvage anything I can.

Oct 18, 2006My old 21" studio monitor used to automatically degauss everytime it was restarted. It also had a 'degauss' button in the software calibrator.

IMac (Intel) :: On Startup Apple Logo Briefly Turns Red With Dark Blue Background
Jun 23, 2014I purchased a new late 2013 27 inch iMac 3.4Ghz i5. The only thing I did after pulling it out of the box was restore Time Machine from my previous iMac. On startup the machine boots as expected, but gets interrupted by the screen turning a dark blue, and the apple logo turning bright red, for about a second or so, then boots as normal, and opens Mavericks. I've spoken to Applecare - they suggested I re-install Mavericks, which I did. The problem is still there. I've done a hardware diagnostics test - no problems. Though I wonder if it could be a faulty graphics card? As far as I'm aware there are no other issues with the iMac. The machine is under warranty but would love to solve this if possible.
