笔记本插拔电源声音怎么关

Our laptops allow us to be more mobile than ever before, but still always in search of convenient outlets to charge them. If you are in the middle of charging a laptop and need to move to a different outlet while it is still running, will it damage it? Today’s SuperUser Q&A post has the answer to a curious reader’s question.

我们的笔记本电脑使我们比以往任何时候都更具移动性，但仍始终在寻找方便的插座来为它们充电。 如果您正在为笔记本电脑充电，并且需要在笔记本电脑仍在运行时将其移至其他插座，会损坏笔记本电脑吗？ 今天的“超级用户问答”帖子回答了一个好奇的读者的问题。

问题 (The Question)

SuperUser reader Donna wants to know if it is safe to unplug a laptop while it is running, then plug it back in:

超级用户阅读器Donna想知道笔记本电脑在运行时是否可以安全拔出电源，然后将其重新插入：

Am I damaging my Hewlett-Packard laptop by leaving it running, unplugging it from an outlet, then walking a few feet to the next outlet and plugging it back in? My brother-in-law says that I am.

我是否正在运行，从插座上拔下电源插头，然后步行几英尺到下一个插座再将其插回电源，以损坏Hewlett-Packard笔记本电脑？ 我brother子说我是。

Is it safe to unplug a laptop while it is running, then plug it back in?

在笔记本电脑运行时拔下电源插头然后再插回电源是否安全？

答案 (The Answer)

SuperUser contributors Journeyman Geek and Schwern have the answer for us. First up, Journeyman Geek:

超级用户贡献者Journeyman Geek和Schwern为我们找到了答案。 首先，《 Journeyman Geek》：

No, it should be fine. Laptops are designed to switch between battery and main power.

不，应该没事。 笔记本电脑旨在在电池和主电源之间切换。

Stuff to watch out for? Tripping hazards. While barrel connectors are fairly robust, they have been known to fail, especially with a sideways “impact” force. Completely unplugging the power connector would mitigate both this and the risk of tripping. There are special mechanisms for laptop HDDs that park the head in case you drop it.

需要注意的东西？ 绊倒危险。 尽管桶形连接器相当坚固，但众所周知，它们会发生故障，尤其是在侧向“冲击”力作用下。 完全拔下电源连接器会减轻这种情况和跳闸的风险。 笔记本硬盘驱动器具有特殊的机制，可将其放下以防万一。

In essence, anything that can kill a laptop while moving it would kill it anyway. I have had a few desktop divas experience the same failure modes, so it is not especially dangerous to move a laptop.

从本质上讲，任何会在移动笔记本电脑时杀死笔记本电脑的东西都会将其杀死。 我曾经有一些台式机的Divas经历过相同的故障模式，因此移动笔记本电脑并不是特别危险。

Followed by the answer from Schwern:

随后是Schwern的回答：

Your brother-in-law has an outdated view of how rechargeable batteries work. Older laptops used NiCd batteries, which were susceptible to the memory effect. Their maximum charge could be reduced if they were repeatedly partially discharged and then charged. There were all sorts of attempts to mitigate this, including waiting until the battery was discharged before charging it again. It is debatable whether the memory effect was real or not.

您的姐夫对可充电电池的工作方式已过时。 较旧的笔记本电脑使用的是NiCd电池 ，容易受到记忆效应的影响 。 如果将其反复部分放电然后再充电，则可以减少其最大电荷。 为了缓解这种情况，人们进行了各种尝试，包括等到电池放电后再充电。 记忆效应是否真实存在争议 。

Modern laptops use lithium-ion batteries, which have no such problem. They also have sophisticated hardware and software to monitor the battery, keeping it in good condition and preventing anything a consumer is likely to do from harming it.

现代笔记本电脑使用的锂离子电池没有这种问题。 他们还拥有完善的硬件和软件来监控电池，保持电池处于良好状态，并防止消费者可能做的任何事情伤害电池。
