电脑突然充不上电是为什么

一、电池坏了电池是笔记本充电和蓄电的重要工具，当笔记本电池自身出现故障时，自然就充不进去电了。电池坏了可能是因为电池烧坏了或者是因为电池损耗严重造成的。此外，当大家频繁充电或者过度充电时都会影响电池的使用寿命，加速电池的消耗和损伤。电池出现问题，这个时候就需要更换新的电池。二、笔记本充电器或者充电线坏了笔记本电池没有问题的话，其充电器或者充电线坏了也是造成电池不能充电的重要原因。充电器插ke neng shi dian yuan shi pei qi gu zhang ，ke yi chang shi shi yong ti huan fa jie jue wen ti ，ru guo shi dian chi gu zhang ，yi ban hui chu xian qu diao dian yuan shi pei qi xu hang shi jian bu dao ji fen zhong ，huo shi zhi jie jian ce bu dao dian chi zhi xu yao geng huan "

电脑充不上电是使用电脑过程中一个很常见的问题。可以通过更换充电线，检查电源适配器，更换电池，重装电池等方式解决。可能是电源适配器故障，可以尝试使用替换法解决问题，如果是电池故障，一般会出现去掉电源适配器续航时间不到几分钟，或是直接检测不到电池只需要更换

1、电池的自我保护： 电脑会对电池进行过充保护，可工断开电脑电源，对电脑电池进行放电处理，在电脑提示低电量后连接电源适配器进行充电即可。2、电源适配器故障： 电源适配器即电脑充电器，可采用新的电源适配器为电脑充电来判断是否是由电源适配器损坏而引起的充电故障。电源适配器损坏则更换新适配器。3、电池故障： 电池故障表现为充电进度一直显示100%,实际电源适配器续航时间很短，或是充电故障。电池使用dian nao chong bu shang dian shi shi yong dian nao guo cheng zhong yi ge hen chang jian de wen ti 。ke yi tong guo geng huan chong dian xian ，jian zha dian yuan shi pei qi ，geng huan dian chi ，zhong zhuang dian chi deng fang shi jie jue 。
