My iBook G4 struggles to turn on, why?

I recently got this thing. It started at OS X 10.5.1 and I updated it to OS X 10.5.8 almost immediately. It was running like a dream last night (I have had it less than 24 hours) and then I shut it down for the night and left it to charge. This morning when I tried to turn it on, pressing the power normally did nothing. I held down the power and it made this loud BEEEEP and then the ready light flashed a few times. Still nothing. I repeated doing this about 4 times before it got to where it is now, up and running. Is there a reason for this? Is it the updated system? I barely put ANYTHING on the hard-drive memory wise, I just have a few pictures on here as of now and some small video files, not even full movies. That's it. Is it defective? Should I be contacting the seller over this? Or is it something I've done to it?

iMac, iOS 5.0.1

How many times does it beep? There is likely a RAM problem.


The power on self-test resides in the ROM of the computer. This test runs whenever the computer is turned on after being fully shut down (the power-on self-test does not run if the computer is only restarted).


If a fault is detected during the test, you will not hear a normal startup chime. Instead, the system will beep as explained below. If you experience one of these beeps, you may call your Apple Authorized Service Provider for additional troubleshooting assistance.


1 beep = no RAM installed

2 beeps = incompatible RAM types

3 beeps = no good banks

4 beeps = no good boot images in the boot ROM (and/or bad sys config block)

5 beeps = processor is not usable


In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.

Hello,


There could be any number of reasons why your iBook done that. It could be something a simple as a loose or faulty memory module installed under your keyboard. What I suggest you try doing is resetting the PMU should this happen again. If you continue to experience this problem, then I would run he Apple hardware test just to get some diagnostics on this fault.


Best of luck
