Hello,

When I run echo "\_SB.PCI0.SBRG.EC.AC1 60" | sudo tee /proc/acpi/call, the value of AC1 is not changed... Isn't it supposed to change?

If I acces directly the port of the Embedded Controller (outb(ADR_AC1, EC_DATA), with ADR_AC1=0x08 in my case, and EC_DATA=0x62), I manage to change the value.
