情况:笔记本电脑电池有时会被检测到,一直供电,检测到后即可充电。
我想问一下问题可能是什么以及如何解决。电池是 ThinkPad Battery 57++ (9 芯) - 详细信息请参阅 CLI 输出。
是的T540p
,它运行得很好,我喜欢它。然而,尽管继续供电,但电池时不时会“未检测到”。我在其上运行 Linux,但我仍然在其上安装了 Windows 10,问题也在那里重现。当我输入这篇文章时,电池状态发生了两次变化 - 笔记本电脑的电源没有中断(现在没有插入电源)。上周有几次笔记本电脑无法启动/恢复,除非我插入电源并取出电池,然后启动/恢复它。
当电池处于“未检测到”状态时,我可以在 gnome 3 面板中看到“估算”电量,并且閣下(Thinkpad 笔记本电源管理)输出为:

当检测到电池时,我有以下输出:

我已经更换了电池和电源适配器,因为旧电源适配器有时会发出咔嗒声。我已经将 BIOS 更新到最新版本(之后我又听到了旧充电器的咔嗒声——我已经很久没有听到这种声音了——然后我换了新的)。有时从右到左轻敲电池组背面后,电池的状态会发生变化。可能是电池连接器数据针插座之一有问题吗?如何排除故障?我仍在卖家的一年保修期内。
