怪问题 L14 Gen1

AzureLabs

整得一台L14 Gen1 (20U6) 但是时常自动断电/并存在电池消失的情况（dmesg中出现数十次thinkpad battery） 充电亦不甚稳定

亦有拔下充电器就无法开机情况发生
用某个45w PD的1+充电器启动时电脑鸣叫不止 用Lenovo PC Diagnostics解读得0002（内部总线错误） ; 但是换了一个充电头就变正常了

不知是电池还是电脑电源部分有问题

可能性如下，原45W充电头没有备注品牌，杂牌容量虚标？握手协议与L14不兼容？口碑品牌比较自律可信。换了一个充电头就正常了，但却不标注品牌与容量？L14主板漏电，45W电源适配器拖不动？表述欠完整，只能帮到这里了。

1. 一加ace1/10R/Realme GT NEO3自带的c口充电器 VCK8HACH （可能有时候握手握不上？）
2. 换的是联想原装的65w的大电源

3. 前往售后 人家一看发现 电池接口接触不良 难怪充不上电 （讲真想不到）
