Repair and modification guidance
While these models share the same main motherboard, there can be differences in implementation. For example, the IdeaPad S145 and the business-oriented V15-IKB may have different hardware configurations or slightly different BIOS/firmware requirements, even though the board itself appears nearly identical. A BIOS dump from one model might not work perfectly on another without modification .
