Did a full reinstall with vanilla settings, using tlp - C8 package state working now.
Updated to 1.12 BIOS, C8 still working.

I'm able to get into pc10 by disabling the memory card device in the BIOS. Reported by PowerTop 2.9 and Arch Linux with 4.15.7-1-ARCH. Could someone else with X1C6 verify?

I also remembered that I also configured some settings for i915 in /etc/modprobe.d/i915.conf:
$ cat /etc/modprobe.d/i915.conf
options i915 enable_rc6=7 enable_fbc=1 semaphores=1 enable_guc_loading=1 enable_guc_submission=1

@PastExcitement: Thanks for testing! Did you add the i915.conf to your initramfs? Otherwise HuC/GuC firmware loading doesn't work: https://wiki.archlinux.org/index.php/In … re_loading

@PastExcitement: Which memory card device is in the X1G6? Does it work if you disable the cardreader in the sysfs instead of BIOS? By the way, kernel 4.15.8 has this commit:
* 77a4aeb4ce78 mmc: sdhci-pci: Fix S0i3 for Intel BYT-based controllers

@progandy: The X1C6 appears to have a Realtek Semiconductor Corp. memory card reader. However, I re-enabled it, upgraded the kernel to 4.15.8, and powertop is reporting quite a bit less power used by it (over 2W with 4.15.7 to 286 mW with 4.15.8). I'm not sure if that commit you mentioned was related, but I do see a noticeable decrease it power used by that device (at least based on powertop).
I haven't tried disabling it via sysfs. I suppose I could look into that.

@PastExcitement: Can you still enter pc10 with the reader turned on?
Offline
Power appears to be 0mW for the memory card reader with the command:
echo "2-3" | sudo tee /sys/bus/usb/drivers/usb/unbind
Offline
@johannesg00: With the reader turned on, turbostat is still reporting pc10 when the display is off:
# sleep 1; xset dpms force off; sleep 1m ; xset dpms force on
# turbostat --show Pkg%pc2,Pkg%pc3,Pkg%pc6,Pkg%pc7,Pkg%pc8,Pkg%pc9,Pkg%pc10

So it looks like it should work now pretty well. Now I'll just have to decide if a 14" screen is enough for me, I still prefer 15.6

From https://forums.lenovo.com/t5/Linux-Disc … rue#M10682, after adding the kernel parameter
acpi.ec_no_wakeup=1
my X1C6 went into pc10 almost 100% during s2idle.
