The Lenovo IdeaPad 3-14ABA7 Laptop Supports Single or Dual Drive Configurations Depending on the Battery Installed. (One 2.5" Solid State Drive or Hard Drive + One M.2 NGFF (2280) or (2242) Solid State Drive with the Smaller 38Whr Battery Installed) or (One M.2 NGFF (2280) or (2242) Solid State Drive with the Larger 45Whr Battery Installed) Note: Models that have the larger 45Whr battery installed do not support 2.5" Drives due to the larger battery occupying the 2.5" Drive bay. The M.2 (2242) Drive uses a adapter bracket p/n 5B40S22052 to accommodate for the larger M.2 (2280) slot. If the 2.5" Drive was not installed from Lenovo in models with the smaller 38Whr battery installed, you will need the 2.5" Drive caddy p/n 5B40S22053 and cable p/n 5C10S30217 for installation. M.2 Drives with PCIe Generation 4.0 x4 performance are downgraded to closer to PCIe Generation 3.0 x4 performance due to AMD platform limitations.
