一、需求
1、人在公司坐，昨晚写的文档放在家中电脑忘记Copy了，想要访问家中电脑拿到文档。
2、家中或公司中局域网内有某台电脑（或服务器）要开机，或者批量一键打开局域网内某些电脑
二、必备条件
1、网线连接电脑网口（wifi无线网卡无法网络唤醒）
2、网卡支持网络唤醒功能
三、设置
1、主板BIOS设置
目前测试过的主板：微星PRO Z690-A WIFI DDR4(MS-7D25)、技嘉B75M-D3V、技嘉B85M-D2V
下面以微星PRO Z690-A为例。
主板：微星PRO Z690-A WIFI DDR4
系统：Windows10
路由器：中兴AX5400，TPLink5600和7660
发包程序：C#，下面有源码，或者伸手党可以直接从下载链接获取发布好的应用程序
Del键进入微星BIOS，其他品牌DEL, ESC, F1, F2, F8, F9, F10, F12
- 高级–整合周边设备–网卡ROM启动，设置为允许
- 高级–电源管理设置–Eup 2013，设置为禁止
- 高级–唤醒事件设置–PCIE设备唤醒，设置为允许
2、网卡（Windows）设置
- 控制面板–所有控制面板项–网络连接
- 在网卡适配器点击鼠标右键–属性，弹出的属性对话框中
- 选择网络选项卡–配置
- 选择高级选项卡，将
关机 网络唤醒设置为开启，将魔术封包唤醒设置为开启 - 电源管理选项卡，勾选下面三个选项，允许此设备唤醒计算机。
- 切换为电源管理选项，勾选允许此设备唤醒计算机。
- 关闭快速启动，右击开始按钮，点击“电源选项”，点击“选择电源按钮的功能”;点击“更改当前不可用的设置”，把“启用快速启动”勾选。（这条必须做）
3、后记
- 电脑网线连接网口处，电脑关机状态下有的会有黄灯常量，有的电脑不亮，都能唤醒
- 在设置网卡的时候发现没有
关机 网络唤醒的选项的时候，有可能是网卡驱动或者网卡版本不同，没有此选项也能唤醒。

}四、 外网远程唤醒方案
- 家中放一台微型迷你低功耗计算机或者网关（树莓派、网关、迷你服务器）功耗在10W左右，保持24小时常开，一年电费在一百左右。安装向日葵或者ToDesk设置无人值守，支持电脑和手机App连接。随时随地连接到桌面后，用远程发包软件（文中源码或直接下载打包程序）来远程网络唤醒局域网内其他电脑。
- 使用向日葵开机棒，参照官方设置即可，主要是开机棒开放了mac地址开机。可以使得开机棒不局限于一台计算机开机了。在向日葵的网站上找到开机棒，或者在手机就app中找到，然后输入mac地址，即可。
- 使用路由器（例如TP-Link）自带的域名解析功能
