I've got deep sleep working on Linux Mint working following these instructions (see also #15 ) One problem remains, however, and that's after resume the track pad and the track point is non-functional. Seems like even the device went missing - in the control center it is supposed to be shown next to the "mouse" settings and now it is gone. For other sleep modes I used the following script on wakeup which helped to get it back:

cat /lib/systemd/system-sleep/trackpoint 
#!/bin/sh

# Reinitialize Touch Pad to fix non-working Track Point

case $1 in

    echo -n none > /sys/devices/platform/i8042/serio1/drvctl
    sleep 1
    echo -n reconnect > /sys/devices/platform/i8042/serio1/drvctl
    sleep 1
    synclient TapButton1=1 TapButton2=2 TapButton3=3
;;
esac

My grub commandline

cat /etc/default/grub | grep CMDLINE
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash psmouse.synaptics_intertouch=1 iwlwifi.power_save=1 iwlwifi.d0i3_disable=0 iwlwifi=uapsd_disable=0 thinkpad_acpi.fan_control=1 mem_sleep_default=deep"

My kernel version

uname -a
Linux melisandre 4.17.8-041708-generic #201807180730 SMP Wed Jul 18 07:32:29 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

It does not work here. Anyone facing similar issues?

fiji-flo commented 6 years ago

Maybe this is an issue with the synaptics driver. I'm using libinput and everything works fine. Is synaptics default on Mint, or do you just prefer their behavior?

katakombi commented 6 years ago

They actually do not set it as default as of Linux Mint 19 any longer. I tried libinput but the motion settings come not even close to how conveniently acceleration and tapping work with synaptics. As long as I used s2idle I had no troubles using synaptics. So maybe I'll test Si03 again...

katakombi commented 6 years ago

Okay I've double-checked it, and here's the thing:

I tried using libinput in favour of the X11 synaptics driver, but the outcome is the same. Every second time or so my track pad/track stick freezes and won't work unless I do a cold start or shutdown.
I tried to use Si03 but it still reports that it is using s2idle - so not sure if I did something wrong. Nonetheless it consumes almost 2W which is ridiculous since the idle power consumption is just around 2.5W. Moreover, the freezes occasionally happen there, too.

I have the model with NFC and I've read somewhere that the track pad issues are worse there. It's a shame but most likely I'm going to return the device fully functional sleep mode with track pad / track point is crucial to me.

I also observed about ~2-3W power consumption during sleep also after having enabled S3 sleep mode:

$ dmesg | grep -i "acpi: (supports"
[    0.143737] ACPI: (supports S0 S3 S4 S5)

Comment: I'm a rookie when it comes to parsing and troubleshooing the boot logs (dmseg), but as far as I could tell, I did at least not see any errors, so I think I've applied my tweaks correctly.

This morning, I found a comment about launching the kernel with command-line option acpi.ec_no_wakeup=1 (*):

This acpi param is supported from v4.13, it is simple to reduce the power consumption.

If it meets your requirement, then no need to patch DSDT which is more complex.

Power button can wake up system.

My kernel is (>= 4.13):

After adding this (sudo emacs /etc/default/grub, appended acpi.ec_no_wakeup=1 to GRUB_CMDLINE_LINUX_DEFAULT="...", saved, then sudo update-grub), and rebooting, I did a couple of 30-90 minute sleeps, and am now seeing ~0.65W during sleep. Yeah! From 'Power Statistics' Ubuntu 18.04 and also:

(*) According to that comment, the DSDT patch is not needed for this. I don't know how to undo the patch, so I cannot confirm. Will reflashing BIOS 1.25 remove the DSDT patch?

Closing this, since Lenovo added S3 support.
