Hi, for you and all people without S3, could you try :
cat /sys/power/mem_sleep

sudo dmesg |grep ACPI|grep supports

And find kernel: ACPI: DSDT 0x...(remove by me) ...(remove by me) v02 LENOVO CB-01 00000003 INTL ...)
Do you have 00000002 or 00000003 ?
I think sudo dmesg |grep ACPI|grep DSDT will work
or just sudo dmesg |grep DSDT

Thanks

I contact them, for Lenovo it's not specified it is an Linux laptop, so it is not a problem.
The problem is reported by the person answer me, but we don't have tracking or any-else.

You can check an alternative BIOS, the problem seem to be created by a deactivation of the S3 in the BIOS. We have a limited bios, but people have found in another model, it's just a switch to enable in the dump. www.bios-mods.com can modify your dump to enable this.

Have a good day
