联想LePad A1-07平板电脑开机提示电池激活记, 原创:联想LePad A1-07平板电脑电池激活记 一台联想LePad A1-07平板电脑，因放置半年后无法开机，也无法对电池充电，充电时的电源指示灯也是亮的，只是无论如何都无法开机，但在充电状态下按下开机键屏幕亮起来，并显示如下图: 显示大约几秒时间后黑屏，无任何显示。 因机子已经过了保修期，只能考虑自己动手处理了。根据这一显示，还有电池无法充电的现象，可以确定是电池因放置太久而进入休眠状态，此时电池是无电压输出的，机器检测不到电池才会有上面的显示。此时用外接电源的方法，是无法启动的。处理方法: 一、 拆机。拆机方法是用信用卡或者专用的拆机工具从音量按键旁边开始拆下白色后盖，拆下后如 下图: 该机使用的是锂聚合物电池，容量是3700MA，充满电的电压是4.2V左右。上图蓝色框内的是电池，用工具拆下红色圈里的螺丝后，可取后盖。拆下后盖后，可以取下电池。 are some differences in level of development of the various modes of transport, leading to traffic levels have a greater imbalance.
