Hello,

Trying to help my Daughter solve her computer problem from 900 miles away.

She has an Imac G4 with system 10.4

Currently she has a grey screen with no sad Mac only the spinning
beach ball.

She has shut down and rebooted

She has unplugged every thing and replugged them.

She has has a cable ISP sbcglobal

She is unable to get the CD drawer to open from the keyboard.

Any and all suggestions are welcome.

TIA

Don Whitely

First, try unplugging from the internet and booting.

Let it run, don't be impatient. Let it run overnight, for instance, and see if it eventually comes up.

Try removing RAM and rebooting.

To open the CD drawer, have her try holding the mouse button down and rebooting.

Dave,

Thanks for the suggestions we will try it when I call her tonight.

You know, this brings to mind something that I've been curious as hell
about.

There've been some occasions where, for some reason, my ISP's connection
has died -- not the router or the phone line, just the ISP -- and, when
attempting to reboot, the G4 takes _forever_ -- and I mean,
_for_friggin'_EVER_, and it's made me wonder:

Does my G4 actually _have_ to be able to see the Internet in order to
boot? And, when not initially seeing it, is the OS actually _designed_
to _continue_ to try and find the Internet until something inside the OS
decides it's OK to "give up" and finish booting?

(this would be happening with the G4 plugged into the router, which
would still be switched on and connected at the time of the ISP-less
reboot attempt)

Thanks in advance,

Signature

If you don't have a startup disk designated, and are connected to a
network, then your Mac will search for a network drive to boot from.

Ahh, ha. The plot thickens. Thanks!

If you're configured for ipv6 instead of ipv4, it could take a while
longer before it times out, too.

Thanks; I'll have a look.

I've already double-checked my Startup Disk; sure enough, it shows the
internal HD (as I thought...), last choice I made.

No. It does not. Your computer will boot just fine with no network
connection whatsoever--and boot quickly.

Certain circumstances may make your computer take a very long time to
boot. If your computer gets an IP address using DHCP or PPPoE, and the
server that is supposed to give it the IP address is returning some
bizarre response that the computer does not understand, it may keep
trying...and trying...and trying. Booting with the network cable
disconnected should fix this.

That's pretty much what's happening, and always when trying to reboot
after discovering a dsl outage, and I'd almost bet it was while the
network cable was still hooked up...

Thanks,

Hold the mouse button down while turning on the power.

>Any and all suggestions are welcome.

Sounds like she needs to zap the PRAM and/or reset the NVRAM:

http://docs.info.apple.com/article.html?artnum=2238
http://docs.info.apple.com/article.html?artnum=42642

This will clear up any possible corruption in these that might becontributing
to this problem.

If that fails, try to boot from your install CD/DVD and run the Disk
Diagnostics and repair any problems.  Also, run repair permissions
(just to be safe).  

Next, remove and reseat the RAM (if you added any).
