Thank you very much. A couple of questions:

1. Where is the resume script? I have tried to locate it but cannot find it.

2. I tried ACPI once but it did not work well. Can it be configured to 
work smoothly on a 600x? Is there a howto?

Thanks,
Dan

The system is FC2 with a custom kernel on a 600x. The system goes into
suspend on lid closure on battery however it will not suspend with AC
on. Is there a way to configure a 600x to suspend on lid closure? Where
are the suspend parameters defined to distinguish between AC and battery?

Seems you&acute;re using APM. There is no way to get the TP to suspend on lid 
closure if a) system is running on AC and b) a PCMCIA-card is inserted. Some 
consider this a bug of the APM bios, I think this behaviour is by (bad) 
design (as the T20 has the same "bug").

The operating system doesn&acute;t get a notice about the APM event if the BIOS 
denies it. You can do a "cardctl eject" before closing the lid and add a 
"cardctl insert" to your APM script.

If ACPI supports all features you need on your system you can also switch to 
ACPI. ACPI is handled by the operating system rather than the bios, so you&acute;ll 
get full control about the events and the actions to be done.
