Problems getting Ibook to Sleep - Help!

[mikejhsmith]

Hi,
the other day my Ibook G4 refused to go to sleep. Now, no matter what I do, it won't sleep anymore.

- Clicking the apple and choosing sleep does nothing.
- Pressing power and choosing sleep does nothing.
- Closing the lid does nothing.!!!

This is the same with or without power - without just means it runs down then turns off.

And yes the Energy Saving settings are as they used to be and not on 'never'

Any help would be so much appreciated - I am going nuts!!!

Thanks

Mike
