我有一台使用了 6 个月的联想 T14s Gen 3（英特尔）笔记本电脑，装有 Ubuntu 22.04.2。它突然死机了，所以联想更换了主板。现在指纹读取器不允许我记录指纹。我在 BIOS 中对指纹读取器进行了“出厂重置”。我还（在此之前）尝试使用 fprintd 删除所有记录。
但是现在/仍然，当我运行“fprintd-enroll”时，我得到：
Using device /net/reactivated/Fprint/Device/0
Enrolling right-index-finger finger.
然后它等待。我触摸指纹读取器，它立即中止并显示：
Enroll result: enroll-disconnected
如果我指定不同的手指，情况也是一样。
sudo lshw有显示，但我没看到指纹识别器
*-input:7
product: Power Button
physical id: 9
logical name: input2
logical name: /dev/input/event2
capabilities: platform
我没看到任何与指纹相关的ls -l /dev东西。
我sudo journalctl -b 0发现这一点，我认为身份验证只是选择不使用它而采用输入密码的方式(??)：

还有这些：

顺便说一下，每一秒都会有一条这样的消息发送到日志中：

如果存在硬件问题，联想愿意提供帮助/修复。但它似乎识别出我碰过它，所以我认为一切都必须连接起来。我该如何让它工作？
