过去几天，我的笔记本电脑会毫无预警地以不同的时间间隔随机重启。它只会显示黑屏并重新启动 PC。我不认为这是 CPU 温度的问题，因为 PC 感觉很冷。
我在 BIOS 上进行了内存和驱动器测试，两者都通过了。我怀疑这与网卡有关，因为每次 PC 随机重启时，wifi 都会消失，并且只允许通过以太网连接。有什么办法可以修复它吗？
这是我的笔记本电脑的温度，使用传感器命令：

acpitz-acpi-0

temp1: +52.0°C (crit = +226.8°C)
temp2: +20.0°C
有人建议我检查/var/log/syslog一下，这是上次随机重启时发生的情况：

答案1
我终于可以修复它了。原来是“ACPI bios 错误”导致 PC 重新启动。
我通过编辑 GRUB 的配置文件修复了这个问题：
以 root 身份打开文件，例如运行
sudoedit /etc/default/grub
更改行开头GRUB_CMDLINE_LINUX_DEFAULT=以包含参数libata.noacpi=1，以便在编辑后显示，例如
GRUB_CMDLINE_LINUX_DEFAULT="libata.noacpi=1"
保存文件并退出，然后运行此命令：
sudo update-grub
重新启动它就可以正常工作了。
