如今，有大量来自不同制造商的笔记本电脑，每个制造商都必须记录他们生产的每个系统。大多数笔记本电脑制造商使用一个简单的东西，称为 服务标签^{(Service Tag)}，这使他们能够查看您的笔记本电脑必须提供哪些硬件才能提供更好的帮助。

如果您想找到此服务标签，您可以使用多种方法。从 PowerShell^{(From PowerShell)}或命令提示符 -^{(Command Prompt –)}如果标签从笔记本电脑下方被刮掉，这两种工具都可以让您找到标签。

如何在Windows笔记本电脑上查找服务标签^{(Service Tag)}

Windows 11/10笔记本电脑上查找服务^(Service)标签，请按照以下步骤操作 -

1. 在笔记本电脑下找到它
2. ^{(Find Service)}使用Windows PowerShell^{(Windows PowerShell)}查找服务标签
3. ^{(Find Service)}使用命令提示符^{(Command Prompt)}查找服务标签
4. 检查 BIOS。

要了解有关这些步骤的更多信息，请继续阅读。

1]在笔记本电脑下找到它

每个制造商都会在笔记本电脑下方贴上包含服务标签的标签。它可以是英文字母或数字和字母的组合。您可能会发现服务标签为 S/N，它代表 序列号^{(Serial Number)}。也就是说，服务标签和序列号是一样的，如果你已经拿到了序列号，就不需要再去找服务标签了。

如果您的笔记本电脑下方的贴纸由于某种原因损坏，您可以使用命令提示符^{(Command Prompt)}和Windows PowerShell来完成相同的工作。一个简单的命令可以让您获得您正在寻找的服务标签或序列号。

2]使用Windows PowerShell查找服务^{(Find Service)}标签

要开始使用，请按 Win+X 打开菜单并选择 Windows PowerShell。然后，输入以下命令-

wmic bios get serialnumber

它立即显示结果。如果需要，您可以从那里复制序列号并在将来使用它。

Jose Deras说，你也可以使用这个：

Get-WmiObject Win32_BIOS SerialNumber | select SerialNumber

3]使用命令提示符^{(Command Prompt)}查找服务^{(Find Service)}标签

如前所述，可以使用命令提示符在^{(Command Prompt)}Windows 10笔记本电脑上查找服务标签。为此，在任务栏^(Taskbar)搜索框中搜索“cmd”，然后单击单个结果以打开命令提示符。然后，输入这个命令——

wmic bios get serialnumber

与PowerShell一样，命令提示符^{(Command Prompt)}以相同的方式显示序列号。

1] Find it under the laptop

Every manufacturer put a sticker under the laptop containing the service tag. It can be a combination of English letters or digits and letters. You may find the service tag as S/N, which represents Serial Number. In other words, the service tag and serial number are the same, and if you have already got the serial number, there is no need to look for the service tag.

If the sticker under your laptop has been damaged for some reason, you can use the Command Prompt and Windows PowerShell to get the same job done. A simple command can get you the service tag or serial number that you are looking for.

2] Find Service tag using Windows PowerShell

To get started, press Win+X to open the menu and choose Windows PowerShell. Then, enter the following command-

wmic bios get serialnumber

It shows the result immediately. If needed, you can copy the serial number from there and use it in the future.

Says Jose Deras, you can also use this:

Get-WmiObject Win32_BIOS SerialNumber | select SerialNumber

3] Find Service tag using Command Prompt

As said earlier, it is possible to use the Command Prompt to find the service tag on Windows 10 laptop. For that, search for “cmd” in the Taskbar search box, and click on the individual result to open Command Prompt. Then, enter this command-
