Sometimes you need to work on hardware components, like a motherboard, outside of the computer case, but is it safe to do so with the hardware in question powered up? Today’s SuperUser Q&A posts looks at precautions one should take with an endeavor like this.
有时，您需要在计算机机箱外部处理硬件组件，例如主板，但是在有问题的硬件加电的情况下这样做是否安全？ 今天的SuperUser Q＆A帖子着眼于应采取的预防措施。

(The Question)
SuperUser reader misha256 wants to know if it is safe to power up a motherboard outside of its case:
SuperUser阅读器misha256想知道是否可以在机箱外加电：
I have a new motherboard which needs a BIOS update to support a new CPU. Thankfully, I have an old (compatible) CPU handy. My plan is to install the old CPU, update the BIOS, then install the new CPU. I would prefer not having to mount the motherboard in a case just to do the BIOS update bit.
我有一块新主板，需要更新BIOS才能支持新CPU。 幸运的是，我有一个旧的(兼容的)CPU。 我的计划是安装旧的CPU，更新BIOS，然后安装新的CPU。 我宁愿不必只是为了进行BIOS更新位而安装主板。
Is it safe to power up the motherboard outside of its case? My understanding is that the case provides grounding for the motherboard. Could the lack of grounding be an issue?
在机箱外部为主板供电是否安全？ 我的理解是该机箱为主板提供了接地。 缺少接地是否会成为问题？
Is it safe to power up a motherboard outside of its case? If so, what precautions should misha256 take?

(The Answer)
SuperUser contributors mvp and Ricky have the answer for us. First up, mvp:
超级用户贡献者mvp和Ricky为我们提供了答案。 首先，MVP：
Yes, it should be safe. Just be sure to put your motherboard on something non-conductive, like a cardboard box, and it should not touch anything that conducts electricity, including your main computer case. I have done this a few times. If you stop by almost any computer shop, technicians do this sort of thing routinely.
是的，应该很安全。 只要确保将主板放在不导电的物体上(例如纸板箱)，它就不能接触任何导电的物体，包括主机箱。 我已经做过几次了。 如果您几乎在任何一家计算机商店都停下来，技术人员会常规地执行此类操作。
Followed by the answer from Ricky:
随后是Ricky的回答：
Yes, you can power up the motherboard outside of its case. Just take some precautions, like laying a piece of cardboard underneath the board, and you are good to go.
是的，您可以在机箱外部为主板加电。 只需采取一些预防措施，例如在板子下面放一块纸板，就可以了。
Also, the human body contains a static charge, so ground the static by touching a grounded appliance or wiring a ground circuit. Static charge in the human body might damage the sensitive electronic components on the motherboard.
另外，人体中含有静电荷，因此请通过触摸接地的设备或对接地电路进行接线来将其接地。 人体中的静电荷可能会损坏主板上的敏感电子组件。
