The second level sits roughly flush with the top of the controller die, providing four electrical contacts on one side and two on the other that are connected to the six pins of the controller by gold ball bonds. I didn’t measure connectivity from these pads to package pins or the crystal, but based on the general floorplan of the device my educated guess is that the four corner pins connect to the package pins, while the two center pins connect to the quartz crystal (sitting above the controller on the third level).

这款笔记本有几处亮点值得关注：其一，延续联想游戏本一贯出色的键盘手感（难得的是配备带数字键区的全尺寸键盘）；其二，虽定位入门却标配16GB 4800MHz DDR5高速内存，且预留扩展槽最高支持32GB。固态硬盘同样支持扩展——初始512GB M.2 PCIe 4.0 NVMe固态硬盘虽显局促，但双插槽均支持最高1TB容量。
