Ibook not starting Mac OS X...keeps freezing up and asking to be rebooted

Hi,
Having trouble since I installed the latest OSX Update in that the iBook G4 gets to the opening gray screen (with the spinning wheel) and then feezes with a message saying "You need to restart your computer. Hold down the Saturday, Power button for several seconds or press the Restart button."
Restarting or rebooting does not help. Neither does trying to boot up in Safe Mode. Neither does running fsck seem to do anything (it runs but says that the HD is ok).
I'm a little screwed because I left my OSX disk and other software on CD-Rom at home in Canada while I'm on an extended stay in Europe. In other words I don't have the disk to run Disk Utility from startup. Any suggestions? Can I download anything on another computer, and burn a startup disk of some sort. Or do I need to get somebody to break into my apartment and mail me over the disks? Or am I beyond repair and have to take her in to a German reseller for service?
iBook G4 Mac OS X (10.4.3)

An Apple Authorized Service Provider in Europe should be able to help you out with the correct install disks for your iBook. They may charge you to help out, though... Without some troubleshooting using your disks, it might be difficult to figure out what's wrong with your iBook.

IBook not starting Mac OS

Hi, recently a customer bring me an iBook G4 12, the mac didnt start the MAc OS X.
The problem is this:
When the iBook starts it stays a lot in the Apple logo and round loading circle... afeter 10 or more minutes change to a blue screen without any on screen, finally after 10 or more minutes it change to the same blue screen but with the mouse pointer on it, whe I can move the mouse but no more else.
1. I dont have de software.
2. After trying the key SHIFT after the sound scheme y shutdowns after some minutes.
3. If I enter in single user (Apple key + S) and try some commands appears the next:
"/sbin/fsck -fy"
**/dev/rdisk0s3
**Root file system
**Checking HFS Plus volume
**Checking Extens Overflow file
**Checking Catalog file
Invalid node structure
(4, 1152)
**Volume check failed
4. If I try to mount the drive, it also sends an error:
"strategy err 0x5"
"I/O error"
5. If i put logout the ibook try to start but stops as the same problem, blue screen with mouse movement.
Thanks.

Hi there!
Sounds like the hard disk drive may be bad, or have bad sectors or file structures.
Perhaps a bootable disk tool (or the OS X installer which is bootable and has a
disk utility on it) would be necessary to hope to fix the errors on the drive; or to
be able to further study the problem to see if the hard disk drive may have failed.
Since the hard disk drives in iBook G4s are not so easy to exchange with a new
replacement, though that probably is a necessity, some users try to check and
repair the internal drive before replacing it. A tool such as Disk Warrior is helpful.
And any supported retail version of OS X the machine can use, in appropriate
disc media, should be able to start the computer (hold C on start) and be able to
use the Installer's Disk Utility to repair disk. That may not be enough; but you
can also verify disk to see if it passes the SMART test. Sometimes these do,
but still have issues requiring eventual replacement if they are well-used iBooks.
If you have a second Mac running OS X, you could see if the portable in question
could boot into FireWire Target Disk Mode, and then be seen as an external HDD.
With a FireWire cable, you may be able to see if the iBook's drive could be repaired
from a Disk Utility version in a host computer, so attached. (Use FW 6-pin to 6-pin.)
I have not tried this; so you may wish to check out the Support page for Target Disk
Mode, and other reading to see if there is a problem with this idea!
Good luck & happy computing!

My computer is running SO slow. The intermet also keeps freezing up and I have to turn airport off then back on/refresh before it will work again. I dont have enough space on my start up disc to run certain programs. Easiest way to fix?

Running mac os x version 10.6.8

Easiest way is to have an external drive to which you copy the things you store like pictures, movies, and music
which take up a lot of space. Then delete them fron the main drive and clean it up with one of the maintenance utilities. You can readily access the external drive's contents whenever you wish.

Reh... Doesn't work on my 2012 Mac mini. A function key set in Sys Prefs worked in Leopard and Lion on my MB but I cannot get any key to work using SysPref Dictation & Speech. It is befuddling and now I have to go to Edit-Speech to turn on and turn off speech to selected text.
I have used Macs and Apple 2es since cave man days and Apple is becoming so befuddling I am wondering if there is even an advantage to it over Windows XP. I spent a lot on this little box, it looks good (the first one had to be exchanged as it wouldn't link to my keyboard ???) but Apple intuitive does no longer seem meaningful.
If speech to text no longer is accessible by short cuts using Fkeys, why bother to have it in Syst Prefs?
Apple is losing its way. The pleasure is gone and no one at Apple seems to care.

Give this a try:
Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

TS2570 My Mac Book Pro will not start up. I ran the AHT and received the following error:

My Mac Book Pro will not start up. I ran the AHT and received the following error: 4SNS/1/40000000:Th0H-90.750. Anyone know what this means?

I have no idea how much it will cost to repair. I don't even know what the exact problem will prove to be. It may be quick if it isn't a motherboard problem. I just don't know. Take it in for a service diagnostic, then they can tell you what is involved.

I did the recent update on my ipad 7.0.4 and now it keeps freezing up and can not use it. Tried reboot and works for a second then freezes right up again. Anyone else have this issue or know a fix?

Madmonkey,
First thing to try is to reset your device. Press and hold the Home and Sleep buttons simultaneously until the Apple logo appears. Let go of the buttons and let the device restart. See if that fixes your problem.
Gaylefromnewhope,
Seems like you tried this all ready and it didn't help.
Next might be to reset all settings.
Settings > General > Reset > Reset all Settings
Note that when you do this you will not lose data but you will have to enter all passwords again.
If that doesn't help you might tries a restore of your iPad using iTunes on the computer you normall sync with. Do a backup and save all data first. Or
Make an appointment at an Apple Store to have your device examined by a technician. Or contact Apple Support.

Hi If you get an error message saying your flash is blocked by firewall or needs updating or similar and you just get the spinning colour wheel try this link
It takes you to Adobe which tells you which ver of flash player you have - you can then see if there is a later ver by clicking on the library and it automatically selects the correct version for you to download.
Worked a treat for me! Good Luck

Ps Don't forget to use a browser other than firefox or you will be there for days.

Try a SMC reset
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
This process helps correct these power issues.
Power

Use a product such as LibreOffice, the iWork applications, or Microsoft Office 2008 or newer to open them.
