bios里設置了 usb powershare但關機的時候還是不能充電
度娘了一下，發現不解決問題，只能放狗了。果然谷歌里搜到答案，是windows的電源策略。
I figured it out. After enabling it in the bios you need to enable the windows power plan to do so. Here is what you do,
1. Right Click the battery icon
2. Go to Power options
3. Click "change plan settings" for what ever plan you want,
4. Click "change advanced power settings"
5. Scroll/click the "USB settings"
6. when you get to "USB selective suspend setting" disable it for both batter and plugged it, this will enable power to the USB when the laptop is off or sleep.
設置后，關機。看看應該有效了。
