怪问题 L14 Gen1
本帖最后由 AzureLabs 于 2024-9-4 17:58 编辑整得一台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

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。 yx2web 发表于 2024-9-5 08:05

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)
