Dear Nereida,

Greetings, this is ASRock TSD.


B450M Pro4 supports Deep Sleep function since BIOS P3.90.
http://asrock.pc.cdn.bitgravity.com/BIOS/AM4/B450M%20Pro4(3.90)ROM.zip

After updating BIOS, please enter to Advance/ACPI Configuration to set the option [Deep Sleep] to [Enable in S4-S5].


Thanks!

All the best,
ASRock TSD
