Apr 6, 2015 6:46 PM in response to ced13079by K Shaffer,The problem may be hardware, such as low battery power or inability for an old
battery to hold a charge; there also could be a problem with hardware, in that
an old computer could have a worn or failing hard disk drive, with bad sectors.
Troubleshooting to find the cause of the issue(s) may involve trying to get it to run
and then once started, be sure it is working off the AC Power Adapter; then try to
boot the computer in SafeBoot mode. Then you could look into system logs in the
Console utility (in utilities folder) and check those reports or logs from the exact
time the problem occurred. Some problems may not register if the computer fails
before they can be written to the hard drive.

If you have the system install-restore DVD media for the OS X installed in the iBook,
that is one way to try & test the computer. If the hard disk drive has failed, you still
could boot from the install DVD media (hold C key on startup with disc in optical drive)
and wait for an undetermined amount of time, for the computer to start from the DVD
so it can be used to test & perhaps repair, or learn of the hard disk drive status.
Given the age and vintage of both the computer and its moving parts, the HDD has
likely experienced some glitch. Could be some damage to sectors on the drive, or
perhaps it was way too full and had other file damage. You could erase & re-install
a new operating system from the booted install DVD media. If no optical media was
included with your iBook G4, you may have to look for retail versions of system OS
which may be increasingly more difficult to find. That is another topic, since the DVD
media which is supposed to accompany the computer have part numbers. The retail
DVD for say, Leopard 10.5 (won't work on iBook G4 800MHz) has a different label
than original media that was with the Mac, new. Those were gray labelled discs.
Most iBook G4 models with faster than 867MHz processor, could use Leopard 10.5
from retail install DVD. Many of the last models shipped with Tiger 10.4 on gray DVD.
Hopefully you can perform some troubleshooting and have those system install DVDs.

Apr 21, 2015 11:42 PM in response to K Shafferby ced13079,I've tried all of the links and followed them, installed mac os x panther from disc and rebooted and the screen only turned on at the login page. When in the installer i opened the disk-utility and the screen went black i also booted the ibook into safe mode but it did the same thing!

Apr 22, 2015 1:06 AM in response to ced13079by K Shaffer,Could be the hard disk drive has sector damages or other faults, and needs to be
replaced with another ATA/IDE older type hard drive. If the computer were checked
over by an expert, and if the HDD was determined to be the cause of failure, then
the answer and path would be clear...
If the computer model is of the correct vintage and you have original installer media
that shipped with it, (Panther, Tiger, etc) it should work if correct to the exact build.
A later retail DVD would be OK if you don't have the original gray-label install kit.
However without a better diagnostic method, the trial-and-error route may be prone
to causing damages to other items inside the computer, since many fragile parts and
wires are inside that could become sources of trouble after replacement of a HDD.
You could try your luck with shipping the computer away for diagnostic testing and
estimate on repairs to include parts, labor, and an offer of a guarantee on the work.
Since iBook G4 models (unless in pristine condition with complete OEM kit, in box)
are not expensive, it is still possible to get PowerPC Apple portables that have been
repaired, at about the asking price for dubious ones that appear on craigslist...
The PowerBookmedic site and also wegenermedia site both show older computers;
and you could probably send a portable away to either one for diagnostic and repair.
I'd had good results + guaranty, with a vintage computer sent to wegenermedia.com.
Could be, if the computer is worth keeping, it may be worth paying to fix correctly.
Or, you could look for a working similar computer to get by for now, at low cost.
So far, my iBook G4 12-inch mid2005 only needs a replacement battery; perhaps a
newertechnologies from OWC would do. Also they have a legacy SSD for older
portables that would work well in an iBook or PowerBook G4 at macsales.com.
Not sure what to suggest, other than tamper with the unit; carefully test the computer
and try an external FireWire400 enclosure with the correct chipset to allow for Mac OS
booting from the FireWire enclosure; if you can find one that'd work with a 2.5-inch
HDD portable size drive, you could test the computer & if you could make it work from
a system on external hard drive, later the HDD could be swapped. Those iFixit guides
can be helpful to some extent. Troubles include remembering where all the different
lengths of screws came from, and all the tiny wires and breakables, which may fail.
In any event...
Good luck & happy computing!
