关机，拔下电源-->电池拔掉再重新插上，然后插上电源开机-->好了，又可以充电了。。。(甚至不关机不拔掉电源，直接重新插拔电池(╯3╰) ，但感觉这较危险)
但这是个临时办法，经常过几天后该问题又重新出现~~~对很少关机的我来说，这简直是受罪。百度了半天也没找到什么办法，无奈还是Google：
该问题英文是 “Plugged in, not charging” 按这个google，可找到不少办法，比百度强多了
办法1：
>Disconnect AC
>Shutdown
>Remove battery
>Connect AC
>Startup
>In Device Manager, Under the Batteries category, right-click all of
the Microsoft ACPI Compliant Control Method Battery listings, and select
Uninstall. WARNING: Do not remove the Microsoft AC Adapter driver or any other ACPI compliant driver.
>Shutdown
>Disconnect AC
>Insert battery
>Connect AC
>Startup
办法2：
Uninstalling and reinstalling power management software in Windows Vista
In order to correct problems with the battery‘s power management software, follow the steps below.
1. Click Start and type device in the search field, then select Device Manager .
2. Expand the Batteries category.
3. Under the Batteries category, right-click the Microsoft ACPI Compliant Control Method Battery listing, and select Uninstall .
WARNING: Do not remove the Microsoft AC Adapter driver or any other ACPI compliant driver.
4. On the Device Manager taskbar, click Scan for hardware changes .
Alternately, select Action > Scan for hardware changes .
Windows
will scan your computer for hardware that doesn‘t have drivers
installed, and will install the drivers needed to manage your battery‘s
power. The notebook should now indicate that the battery is charging.
上述都是卸载重装系统自带的一个电源驱动(下图)，第二个办法操作更简单
还有找到的一些办法：
1- first unplug the charger pin from laptop.
2- right click on the battery icon and select the different plan for the
battery for example if it is set on power saver select 1 from 2 i.e
balanced or high performance.
3- then plug the pin again...
that‘s it.
1. Change in date when you go back in different year it start charging again.
