on PC's (desktop's), when you hit the power switch, the machine shuts down (soft) and this is done due to ATX mobo...

is this the same as laptops? all of the laptop's i've dealt with or can remember shut down the same way (soft), so is it ATX? or something else?

Actualy - even on PCs this is configurable. On Laptops it is even more so. The mechanism is in fact 'ACPI' - Advanced Configuration and Power Interface.

so ACPI is what makes it shut down safely?

so is it possible for an AT mobo shut down softly? if so how?

 

Most old motherboards don't have ACPI, or only in a limited fashion.

And the extra control wire to implement part of ACPI is missing in the AT power supplies usualy.

Much of the PC design is a moving target, with many parts being developed in parallel. ACPI has gone through several versions. The control wire used by ACPI in the ATX standard is only part of what makes up ATX.

cheers for that mate...
