I installed 'acpid' and 'acpi' packages. Then, I supressed the 'acpi=off' entry in the 'lilo.conf' file and ran 'lilo'. I restarted my laptop with the 'acpid' service launched on startup.
I let my laptop running alone and came back ~2 hours later. What works: The screen and the hard disk were off. Maybe my hard disk is managed by my mother board. Moving the mouse putted my screen on. Using my files explorer waked my hard disk. What sould work: The fan always ran. My laptop Sony VAIO PCG-FX301: - CPU: AMD Duron Mobile 800MHz - Memory 256 MB - video card: ATI Rage Mobility P/M AGP 2x - video memory: 8 MB I hope this will help you. J�r�me
