The Lenovo IdeaPad Slim 3s processor has several negative aspects. It often suffers from dull or plodding performance, especially with demanding or multi-threaded tasks, due to cooling limitations that cause CPU throttling.
The processor is generally suitable for light productivity but struggles under heavy workloads. Many models come with non-upgradable, soldered RAM, limiting multitasking capability.
Additionally, the integrated graphics are weak, unsuitable for gaming or heavy graphical tasks. Overall, the CPUs performance is basic and constrained by thermal and design trade-offs.
