联想Thinkpad T480 U15 Bios
故障现象开机
"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
Press the ESC key to continue "
同时测量Type-C 只有5V 无20V 但是测量电池充电电压有12V 不亮机 不充电 不报警 Type C灯橙色 电源灯闪3下黑屏
U15 W25Q80刷程序无用，需要更换全新的W25Q80，如果不换新的会出现校验错误 同时故障无法解决和Bios无关 跟电源也没关系
