T490接充电接口Type C电源问题，症状为：
1. 开机报错，显示：The connected AC adapter has a lower wattage than the recommended model which was shipped with the system. To boot with the AC adapter, please connect the AC adapter which was shipped with the system. Press Esc to continue. 按ESC继续，则可以工作但充电很慢，而且如果电池馈电则无法开机。
2. 开机时，在高性能下充电不如放电快，在电池平衡接段下可以缓慢充电。在关机后，充电相对较快。
3. 个人感觉是Type C 接口协商只能工作在45W模式下。
