我的戴尔 xps-13-9380 笔记本电脑（ubuntu 19.04）上的所有 3 个端口（usb-c）都不再工作了。这些是我的笔记本电脑规格。
我尝试按照以下步骤更新我的 BIOS这些说明。
我也读过这个帖子下载固件更新可以修复该问题：。
但是，它说我需要将 .exe 文件下载到 USB 上。由于我的所有端口都无法使用，显然我无法这样做。
我在终端运行了这个命令
fwupdmgr get-updates
得到了这个结果：
XPS 13 9380 系统固件无升级，当前版本为 0.1.6.0：0.1.6.0=相同，0.1.5.0=较旧，0.1.4.0=较旧，0.1.3.2=较旧，0.1.2.1=较旧
我认为我的固件是最新的？
我运行了戴尔的诊断工具。它说一切正常。我打开/关闭它并重新启动它。但结果没有改变。
除了将其送回戴尔或重置为出厂设置并重新安装所有内容外，我还能做什么？

更新
我暂时解决了这个问题，方法是关机（不是重启而是关机）并拔下连接到端口的所有东西（充电器、USB、扩展坞等），然后将其放置大约一个小时。之后，它会像以前一样正常工作，我现在可以使用所有端口了。但不确定这种状态会持续多久
答案1
fwupdmgr 不会升级您的 BIOS。
首先，我们将检查您的系统上安装的 BIOS 版本：
sudo apt install dmidecode
sudo dmidecode
这将向您显示所有与 BIOS 相关的信息。BIOS
是 DMI 类型 0（通常是第一个条目）。查找“BIOS 信息”。对我来说，它看起来像这样：
# dmidecode 3.1
Getting SMBIOS data from sysfs.
SMBIOS 2.8 present.
29 structures occupying 1999 bytes.

答案2
我的解决方案是关闭计算机（关机而不是重启）并拔掉所有电源。等待一个小时。然后重新启动计算机。
