通过外部电源开关打开PC [英] Switch on PC from external power switch

问题描述

你好！
我有一台PC(Dell，Windows 7)，它是一台较大的计算机(由不同的硬件元素组成)的一部分，位于该计算机的内部.外部机器通过中央开关按钮与电源相连.用户打开中央开关后，必须打开机器(包括PC)的所有硬件.
我的问题是用户无法访问PC本身的电源按钮，因此，在打开外部电源开关但不按下其电源按钮的情况下，PC必须能够唤醒.
我曾尝试通过掉电时唤醒"配置在BIOS中找到配置，但是当我通过Windows正确关闭PC时，关闭外部开关，然后再打开外部开关，则PC不会唤醒.我想发生这种情况是因为通过Windows正确关闭并不会导致BIOS掉电，因此不会唤醒PC.休眠关闭也会发生同样的情况.
有谁知道，检测到电源后如何唤醒PC?我可以通过软件(可能是USB唤醒?)来完成此操作，而无需实际修改PC的电源按钮吗?
有人遇到过同样的问题吗?
非常感谢！

Hello!
I have a PC (Dell, Windows 7), which is part of a bigger machine (composed from different hardware elements) and it is located in the interior of this machine. The external machine is conencted to the power supply via a central switch button. Once the user turns on the central switch, all the hardware elements of the machine (including the PC) must be powered on.
My problem is that the user cannot have access to the power button of the PC itself, so the PC must be capable to wake up when the external power switch is turned on but without pressing its power button.
I have tried finding a configuration in BIOS, through the Wake-Up on Power Loss configuration, but when I shutdown correctly the PC via Windows, turn off the external switch and then I turn on the external switch, the PC does not wakes up. I suppose that this happens because a correct shutdown via Windows is not a power loss for the BIOS, so it will not wake up the PC. The same happens with hibernation shutdown.
Does anyone have any idea, how can I wake up a PC when power is detected? Can I do that via software (maybe USB wake up?) without modifying physically the PC''s power button?
Has anyone faced the same problem before?
Thanks a lot!

推荐答案

如果您的PC没有用于开机的BIOS选项，那么您可以做的工作非常非常有限:大多数都可以-值得联系主板制造商并询问他们.

另一种选择是局域网唤醒"-它只需要一个有线网络连接和一些流量，因此还算不错.我还没有听说过USB唤醒功能(而且大多数PC在电源关闭时都遇到了USB掉电的问题，因此很难理解如何工作).

最好的选择可能是，将电线连接到机箱上的电源开关所连接的位置，并在电源接通时从外部将其关闭-这很容易做到，并且比未来"更具挑战性主板/BIOS特定设置应该会导致PC死机，并且将来需要更换.

If your PC does not have a BIOS option for wake on power on, then you are very, very limited in what you can do: but most do - it may be worth contacting the motherboard manufacturer and asking them.

The other alternative is "Wake on LAN" - it just needs a wired network connection and some traffic to it, so it''s not too bad. I''ve not heard of a Wake on USB (and most PC''s I''ve met power down USB when the power is off, so it''s awkward to see how that would work either.

The best option, probably, it to run a wire to where the chassis power on switch connects, and close that externally when the power comes on - it''s simple to do, and it''s a lot more "future proof" than a motherboard / BIOS specific setting should the PC die and need replacement in the future.
