关机，拔下电源适配器-->电池拔掉再重新插上，然后插上电源适配器开机-->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：没用
>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：没用
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：没用
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.
1. Boot up your laptop with its Battery Installed in and charger plugged in.
2. login and wait until the machine has completely started up.
3. Unplug the charger.
4. Mouse over the battery icon in your system tray.
Initially, the status will only show the battery charge %.
5. Repeat Step 4 until the battery 'Time Remaining' is displayed.(this could take a while)
6. Plug the charger back in and see if it's resolved.
经试验，每一个有用的。。。最方便的办法还是：插着适配器且开机的状态下直接拔下电池后再安上电池。自己已试过多次，电脑运行正常。
