On my PC, I have only recently taken to trying to use the Standby mode, when I shall be back on it shortly. However, the PC immediately starts again, without any prompt from me. Is there something wrong in the Settings somewhere? Any advice much appreciated.
Suspend Mode = S3 ACPI 2.0 Support = Disabled ACPI APIC Support = Enabled
They may be called something different in your BIOS. If I don't have those settings (particularly S3) then it either doesn't go into Standby or restarts almost immediately. I'm not 100% sure but I think your PSU has to support a suspend mode too.
