Hi. Thank's for a hint!
So catting this file gives me next content:
s2idle [deep]
Which kernel version do you use?
The default switches to s2idle based on FADT flag and _DSM on relative new
kernels.
Most systems preload with Windows 8.1 should default to use s2idle.
So I suppose I have s2idle with deep-mode available?
I've tried to select deep by creating mem_sleep_default file, but I can't
(Permission error).
Could you explain how do I switch suspend mode in Linux, if you know?
# echo s2idle > /sys/power/mem_sleep
And to be honest, I don't think that's a correct fix of touchpad problem.
If the system defaults to use S2I, then it’s better to stick with it.
Lots of ODM/OEM don’t really test S3.
Can we somehow cut off the power by hands or send a signal to a system to
shut off a touchpad? Or there are no approaches like that?
I don’t think it’s possible.

Hi.
Honestly, I can't find any information about my acpi suspend type.
There are no options in my BIOS to change it, and I can't determine
which exactly I have. But I suppose I have a S3 because I have suspend
issue.
Can I somehow determine it in Linux? I did a research but found nothing
on the internet.
You can read the default mode from /sys/power/mem_sleep. "s2idle" means,
well suspend-to-idle and "deep" means S3.
