Mac Mini G4 turns itself ON

I have a Mac Mini G4, that is running OS X 10.4.11. After a normal shutdown, Apple, Shut Down, Shut Down, the computer turns itself on sometime during the night. I have turned off Backup (to .mac account), but it still is happening. Any thoughts?

Have you looked into System Preferences>energy saver>schedule? Maybe it's set up to start itself. I have my mother's mac set to start up and shut down automatically. Just a thought.

This is a strange issue. I would try resetting the PMU using these instructions.

  1. Unplug all cables from the computer, including the power cord.
  2. Wait 10 seconds.
  3. Plug in the power cord while simultaneously pressing and holding the power button on the back of the computer.
  4. Let go of the power button.
  5. Press the power button once more to start up your Mac mini.

1.Try a Safe Boot
Mac OS X 10.2 and later Safe Boot includes disk checking and repair. First start your Mac in Safe Mode. To do this, shut down your Mac. Now Turn on your computer by pressing the power key while holding down the Shift key. When you see the Apple logo, release the Shift key. After your Mac fully starts, restart your computer normally without holding any keys/buttons during startup. Note that Safe Boot is slower to boot.
2.Run Disk Utility
Turn your Mac off by holding down the power button for a few seconds. Turn on your Mac and hold down the Command and R keys until you see the Apple logo. Then you should see a "Mac OS X Utilities" window. Select Disk Utility, click your OS X hard drive and select verify/repair disk.
3.Reset PRAM
This may fix your boot failure. PRAM ("parameter random-access memory") stores some of your settings. You may reset PRAM. To do that, turn off your Mac. Now turn on your Mac. Then, immediately, hold down the Option-Command-P-R keys until your Mac restarts. When your Mac is starting up, release the keys.
4.Reinstall Mac OS X
If nothing above works, you may try this. Your Mac needs to be connected to the Internet. See number#2 above. Follow the same steps. Restart your Mac and hold down the Command key and the R key until the Apple icon appears; when you see the Mac OS X utilities window, select the Reinstall option.

Unexpected shut down


Good chances this is a thermal shutdown. if this is the case, the computer is shutting off to protect itself from permanent damage. if your OS is old enough (Snow leopard, I think) then the system logs show what caused the shutdown. it will give a number. anything other than a 0 or a 1 are bad. if I recall correctly 1, 5, 13 are thermal shutdowns. Newer OS's don't seem to show these codes. and Apple does not publish their meanings.

Since you need to clarify exactly what is missing or broken as well as whether this is in reference to software or hardware (usb connected?) and what version of OS X you are running. I can only suggest looking here.

My powerbook G4 froze with flyspin going.. I shut it down but when I restarted it it went to a blue screen with no activity. Clearly it is not starting up OS X. Any ideas what to do?


Boot it into single-user mode holding down Command(Apple) and S buttons when powering up. Then in terminal console, use chkdsk -fy. Use it and use it again until comes back with something like "Volume appears to be OK". Then use command: mount -uw / and then type reboot and try booting normally.

What to do when rebooting Mac and folder with ? is flashing


This icon is an indication that the computer cannot find a working hard drive; or if it has, that it cannot find a viable OS on that drive.
Shut the machine down to power off. Now turn it on and hold down the option key. Do any hard drives appear on the screen? If not, your hard drive has gone bad or has somehow disconnected itself. If so, choose that drive and hit the return key. If your machine boots, login and use System Preferences / Startup Disk to re-establish this drive as your startup drive. If not, this drive doesn't contain a working OS.

My screen is on but just have a small camera in the middle of the screen blinking.. G4 power book can you help?


I seen a blinking folder with a question mark in the middle in folder, in the middle of a display screen, but not a camera.

Either way, you are not able to access your main desktop so that is where I want to help.

A blinking folder with a ? in middle, is an indication that your bootable Mac OS X volume cannot be found.

If you do, I would first recommend you try this procedure first:
(PRAM Reset)
Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} • First, hold in your power button for approximately 10 seconds to do a hard shutdown, if you have not already turned your Mac off.

• Once your Mac is shutdown, you will need to perform what is called a PRAM reset (Parameter RAM)
• Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously .

• Turn on the computer.
• Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
• Now, hold the keys down until the computer restarts and you hear the start up sound for the third time.
• Release the keys and allow the Powerbook G4 to start up.
------------------------------------------------------------------------------
If this still returns you to a blinking ? folder, try this process:
Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} DISK UTILITYYou can use your Mac OS X install disc to repair your hard drive and Mac OS X volume using Disk Utility. Click the link below to try this procedure.
* Apple Support Link:
Use Disk Utility to Repair Disk

Should neither of these processes work and you still boot up to a flashing ? folder, then your only recourse is to use your Mac OS X installation disc and perform an Archive and Install procedure.
----------------------------------------------------------------------------

Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} This procedure also allows you to save your applications, files and folders without the old directory interferring with you then accessing those files and creating a new Mac OS X Directory.

Here is the Apple Support Link for that procedure:
Archive and Install



This should get your Powerbook G4 back to normally functionality without any serious data loss.

HELP!!! I am trying to start my Powerbook G4 but as soon as it turns on I just get a grey screen that says that i need to restart my computer. i tried restarting it like 10 times. what else can i do?


Also, check your RAM bay port to see if one of the RAM boards came dislodged and is not inserted correctly. Could also be one of your RAM boards is not compatible or one of the RAM boards is defective.

The circular timer startup screen NEVER STOPS! Powerbook G4


Hi

Safe Boot is a special way to start up in Mac OS X 10.2 or later when troubleshooting. Safe Mode is the state Mac OS X is in after a Safe Boot. To perform a Safe Boot, hold the SHIFT key as your Mac starts up.

Some features don't work in Safe Mode Safe Mode can be useful for troubleshooting. However, certain Mac OS X features do not work in Safe Mode. For example, you can't use DVD Player, capture video in iMovie, use audio input or output devices, or use an internal or external USB modem. The behavior of some devices such as an AirPort card may vary depending on computer and Mac OS X version.
Safe Mode in Mac OS X 10.5 or later also disables Quartz Extreme (hardware accelerated graphics). Applications that depend on Quartz Extreme will not open, and the Mac OS X menu bar will appear solid even if "Translucent Menu Bar" is enabled in Desktop & Screen Saver preferences.
