我希望我的电脑在连接电源时自动打开

我希望我的电脑在连接电源时自动打开。这不是为了在断电后打开，而是当我远程控制电源插座时，可以从远处打开电脑，而无需有人按下电源按钮。

编辑：我不想恢复以前的电源状态，我这样做的原因是我的树莓派控制的延长线可以打开电源和打开我的电脑（树莓派没有连接到电源开关上的pc) 这样我就可以从那里远程桌面到我的电脑。我对此所做的所有研究都只是为了恢复电源状态，我找不到任何其他信息 Wake On Lan 也是一种可能性，这是我可以从树莓派打开 PC 的另一种方式，但不是我的解决方案想。

BIOS 设置中通常有一个选项，可以在恢复交流电源时始终打开。这对于服务器很有用，但根据我的经验，它并不总是出现在 OEM 系统上。

Second Method

\n\n

If its not work and their is no option of power management through keyboard or any other option then u have to shot the power switch with jumper or keep the wire if power button outer shorted\nFollow the steps

\n\n

Open your cabinet case
On the motherboard locate the front panel pins connectors.
Ensure the 24-pin and 4/8-pin power headers are connected to the motherboard.
Ensure all other necessary power headers are connected to corresponding devices.
Locate the power switch header for the front panel connectors on the board.
These are normally labeled \xe2\x80\x9cPWR_SW,\xe2\x80\x9d \xe2\x80\x9cPWR_BTN,\xe2\x80\x9d etc. I
no cable is connected to the positive and negative headers. Ensure the PSU is switched on and plugged in.
For confirming and testing pins.Find a screwdriver. Bridge the two pins allocated to the power button. The system should turn on.
Now put a jumper to the power pins. And disconnect the power plug and again switch on if computer is switched then OK if not then step 10
Some old motherboards work on with shorting pins but some have new boards restarts reboots on shorting then u can do is two things\nCut or disconnect the wire from power switch side and then connect it with some external switch which shorts it for 2 sec and leave it automatically available in electronic shop or u can. Find online or u can manipulate power switch of case if possible
