Suits owners of listed Lenovo laptops needing

This module fits systems that accept a single 260-pin DDR4 2666MHz SO-DIMM without ECC or registered buffering. It is not for machines that require ECC memory, registered DIMMs, a different pin count, or a different DDR generation. Buyers whose laptops need a higher-density single module or a different voltage should look elsewhere.

260-pin DDR4 SO-DIMM form factor

The 260-pin DDR4 SO-DIMM form factor is the single specification that determines whether this module physically installs and electrically functions in the target laptop. Verify that the service manual for the specific Lenovo model lists a 260-pin DDR4 SO-DIMM slot before ordering.
