编辑：一些新信息：当电脑插入电源时，启动过程非常慢，但当电脑使用电池供电时启动过程则不会很慢......
编辑：只是为了清楚起见，我只询问一个问题，但我提到以前解决的问题，以防它们相关。
我在新的联想 V145-15AST 上安装了 18.04。第一次启动很快，但不幸的是触摸板和 wifi 都不能用。对于 wifi，我在这个帖子并且触摸板也已修复（我升级到较新的主线内核 4.20.0）。
然而，重新启动计算机后，启动需要很长时间（超过一分钟）。
以下是启动时弹出的第一个错误：
Mär 10 12:05:45 Lenny kernel: input: Lid Switch as /devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/device:24/PNP0C0D:00/input/input0

Mär 10 12:05:45 Lenny kernel: ACPI: More than one Lid device found!
Mär 10 12:05:45 Lenny kernel: button: probe of PNP0C0D:01 failed with error -17
（这不是我看到的确切内容，但这些是从中恢复的行journalctl -b）然后启动过程继续，说它没有找到 lvmtab 并且要扫描设备。
这里是输出systemd-analyze：
Startup finished in 4.896s (firmware) + 3.612s (loader) + 34.859s (kernel) + 11.984s (userspace) = 55.351s
