Hey there, lenovotv! 


Welcome to the Lenovo forum discussion! 


Based on what we have gathered, here is the answer to your queries: 


1. Is the SSD user replaceable? 



Yoga C930 –Yes. up to 2TB M.2 SSD’s are tested.

Parts lookup page:


X1Y3 – Yes. up to 1TB M.2 SSD’s are tested.

Parts lookup page:



2. For the 1TB version, is the SSD NVMe PCIe 3.0x4 at 32Gb/s?



Yoga C930  - Yes, up  to SSD NVMe PCIe 3.0x4 at 32Gb/s? can be used.

X1Y3 - Yes, up  to SSD NVMe PCIe 3.0x4 at 32Gb/s? can be used.


3. . Some reviewers have 256GB version made by Hynix which is slower. Is the 1TB SSD made by Samsung or Hynix? 



Yoga C930 - From the parts lookup page, the 1TB M.2 SSD can either be made by Samsung, Hynix, Intel, or Toshiba

X1Y3 - From the parts lookup page, the 1TB M.2 SSD is made by Samsung.


4. Are those two USB 3.0 Type-C ports running independently at full speed? 



Both the Yoga C930 and Y1YC supports two USB 3.1 Type-C Gen 2 ports with a theoretical speed of 10 Gbit/s (1.25 GB/s).


5. It uses the same Intel UHD 620 as the X1 Yoga Gen3. Why it can only drive an external monitor at 3840x2160@ 60Hz while the X1Y3 can drive at 5120x2880@ 60Hz



The Yoga C930 uses a Intel JHL6540 Thunderbolt controller. From, this uses a Displayport 1.2 specification which can support video resolutions of up to 3840 x 2160 (4K).


6. Does it use something like S0 or S3 which could cause compatibility issue with Linux?



I don’t see the any S0/S3 configurations in the BIOS but the X1Y3 is certified to run Linux while the Yoga C930 isn’t.


Linux for personal systems:
