Hi All,

I have an imac G5 running osx 10.4.11.
My problem is that the computer won't come on when I press the power button, eventually, after a number of attempts, it starts up. However, I am noticing it is getting worse and I have to press the power on numerous times before the computer will power on.
Is this a progressive problem eventually leading to me not being able to turn the computer at all or could it be something simple
I have rebooted from the original cd and ran a disk repair, but the problem comtinues

Many thanks in advance

Perhaps the power button is simply not connecting properly/sticking? If it still starts up fine I don't think it is the system, it would more likely be a hardware issue

I can't power up the computer at all now. I've done a bit of trouble shooting and it appears the logic board might need replacing, before I bring the computer to be fixed does anyone know can I save my data/files from the computer as I never made back-up or will I lose them in replacing the board.

Is this expensive to fix or should I consider a new computer?

I have heard the price to buy + install is anywhere from 800 to 1000 $. It is much less if you install it yourself, but you risk making a mistake and causing further problems

FYI...current value of an iMac G5 is approx. $300 bucks...so be careful how much you spend on repairs.

Did you try the suggestion that the power button could be going bad and manually short the leads real fast?

Besides the Motherboard it could be a power supply issue which would be a lot cheaper to replace. The Logicboard is quite expensive BTW.

Do you have any kind of a voltmeter or DVM? If so check all the voltages from the power supply. I am sure there is a chart somewhere on the internet. What model iMac G5 is this? Do you know the basic specs?

Replacing the Logicboard while expensive, would do nothing to your data on the Hard Drive unless the tech is a KLUTZ and hurts the hard drive in someway.

If you find for SURE it's the logicboard, take out the hard drive and purchase a cheap external case that supports the SATA hard drive in the iMac G5 and hook it to another machine.

PLEASE do give us the basic specs so I can check a service manual and get back to you.

Hi dtravis, thanks for the help.
It's a 17" iMac G5 generation 2 ambient light sensor 1.8 ghz. I'm running OSX 10.4.11.
I followed a trouble shooting page on Apple, and removed the back of the computer.
LED light 1 on the logic board came on when plugged in, but when I powered on from the internal power button, no other lights lights came on at all, which it says is a logic board problem. The computer has been acting up the past couple of weeks and eventually refused to power up the other day.

The other thing is I live in Ireland and I'm not aware of any techs other than Apple approved which allows them to cost a fortune, just to look at your machine.

Thanks Chas, Was thinking of new machine anyway, you're right I have got a good run out of it (and this is the first problem I've really had with it, and last : (). My biggest worry here is that through my own stupidity (not backing up data) I will lose all my files but hopefully I'll be able to save them.
Can I boot the iMac from my MacBook and retrieve the data from it?
QUOTE Thanks
