集显模式，应该是需要屏蔽独显甚至可能只有集显版的P1才可以使用65W的C口充电，看看BIOS里能否设置为集显模式（不是discrete或optimus）

UMA是核显。统一内存架构 (Unified Memory Architeture简称UMA)，一般就是指没有独立显卡的机器。

UMA generally stands for unified memory architecture.  UMA is what integrated graphics processors (which are a part of CPUs/APUs) use.
楼上说的对，-Support Type-C 65W Adaptor on UMA model.， BIOS支持只有集显的型号用65 W充电了。。。

感谢各位。和客服联系了下，确实是增加了对集显型号P1或X1E的65w typec电源支持。

P1最新的BIOS能否屏蔽独显，成为集显模式，进而支持65W电源？用100W PD电源测试过。CPU性能相差一半。

有待进一步测试。
