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 itâs better to stick with it.

Lots of ODM/OEM donât 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 donât think itâs 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.
