Но когда говорю

acpiconf -s S1|S2|S3|S4

выводит такую ругань:

acpi0: Sleep state S1 not supported by BIOS
acpi0: Sleep state S2 not supported by BIOS
acpi: suspend request ignored (not ready yet)
acpi: suspend request ignored (not ready yet)
acpi0: device_suspend failed
acpi: suspend request ignored (not ready yet)
acpi0: Sleep state S1 not supported by BIOS
