【求助】连接电源适配器开机时提示电压等级比推荐的低是什么原因

1. T480s （BIOS版本1.39最新版）连接原机自带65W电源适配器，偶尔开机时提示The connected AC adapter has a lower wattage than the recommended AC adapter which was shipped with the system. To use AC power，please connect the AC adapter which was shipped with the system.
2.连接口红电源从来未出现上述情况。
3.请问大家这是什么原因？ 换了个全新的电源适配器还是出现过上述情况。
