Hi
I'm trying to enable suspend to RAM in my laptop with linux, but apparently the laptop doesn't have enable the S3 state, the dmesg output about the S states is: "PM: (supports S0 S4 S5)"
S3 not appear.
When I go to the bios, in the advance mode I found the AICP option, and a menu to enable this

But when I change the ACPI Sleep State to S3(Suspend to RAM), in the next boot the state return to the default value.
Any idea about what's happening?
Mi BIOS version is the last in the website

Hi.
Linux works perfectly, all GPUs work without special configuration, install and work, the same with WiFi . The only one problem I have is this, but in some distributions like ubuntu suspend to ram works (I doesn't know why). I recomend this laptol for linux.

The modern Standby is S3 state, and this appear disable by default and I can't enable it ;(
Run command prompt as administrator and enter command "powercfg /a".
It will show which state this notebook supports.
Either S0 low power idle or S3, from the original post I saw you already see the S0 low power idle == Modern Standby.
You can check again, but I'm assuming that it supports Modern Standby (S0 low power idle) not S3 (traditional Sleep).
