Re: X1 Carbon Gen 6 cannot enter deep sleep (S3 state aka Suspend-to-RAM) on Linux

Judging by this response to another Linux customer, Lenovo is not recommending the X1C6 for linux at this time due to the S0i3 sleep issue.

Re: X1 Carbon Gen 6 cannot enter deep sleep (S3 state aka Suspend-to-RAM) on Linux

I have to install Windows 7 for work related reasons, and Windows Modern Standby and s3 don't work on Windows 7.

 

I need proper s3 suspend to ram support for my WINDOWS.

Re: X1 Carbon Gen 6 cannot enter deep sleep (S3 state aka Suspend-to-RAM) on Linux

@Rydeen Since here are more and more Windows users complaining about shortcomings of "modern standby" in Windows, are there any chances Lenovo might consider improving customer satisfaction of Windows users by letting them choose between both options in the BIOS?

Re: X1 Carbon Gen 6 cannot enter deep sleep (S3 state aka Suspend-to-RAM) on Linux

My experience with S0i3 with Ubuntu 18.04:

- I'm on kernel 4.17.4-041704
- Enable Thunderbolt 3 compatibility mode in the BIOS
- Disable internal card reader in BIOS (under security settings)

- Disable Wake On LAN

- Disable Always USB
- Add kernel flag: acpi.ec_no_wakeup=1

 

After this actions my X1C6 sleeping very long.

Re: X1 Carbon Gen 6 cannot enter deep sleep (S3 state aka Suspend-to-RAM) on Linux

S0i3 on Fedora 28 with

- kernel 4.17.3

- Enable Thunderbolt 3 compatibility mode in the BIOS
- Disable internal card reader in BIOS (under security settings)

- Disable Wake On LAN

- Disable Always USB
- Add kernel flag: acpi.ec_no_wakeup=1

 

Additionally, I am on a X1 Yoga3.

 

My energy rate while in S0i3 is 1.39W (about 3x the rate quoted below).  Even with that power usage rate in S0i3 you'd be losing around 7-8% over an 8 hour sleep cycle.  Under S3 you would expect that to be around 1-2%.

Anyway this is better way for me than patching the DSDT table.
We'll wait for the fix from Lenovo.

Re: X1 Carbon Gen 6 cannot enter deep sleep (S3 state aka Suspend-to-RAM) on Linux

Lenovo - please don't leave loyal customers in the dark - I just replaced my trusted Thinkpad X220 with a new X1 Gen6 and it's shameful that Linux is not supported for something as simple as sleep modes, fingerprint reader or LTE modem (Fibocom) - I'm beginning to regret my purchase now!

Re: X1 Carbon Gen 6 cannot enter deep sleep (S3 state aka Suspend-to-RAM) on Linux

Can I just shut my x1c6 down everytime and avoid all of this? or should I just ask for a refund?

Re: X1 Carbon Gen 6 cannot enter deep sleep (S3 state aka Suspend-to-RAM) on Linux

Linux dual boot question.

 

I currently have an X1 2nd gen, with a dual boot setup  (Windows + Ubuntu) and I'm looking to upgrade to an X1 6th gen with similar dual boot arrangement. 

 

Beyond the sleep problems, are there any issues that I should be aware of?
