电池剩余时间计算错误,满电自动切换至电池供电问题及华硕R556LJ5200电量补丁分享。

429839446

根据daxuexinsheng的[教程] [重新整理逻辑] 电量补丁制作教程制作了华硕R556LJ5200的电量补丁，配合Rehabman的ACPIBatteryManager成功显示电量。



但是现在出现了几个问题。
1、系统计算出来的估计剩余时间错误，导致电池在高电量状态下即出现红色电池图标。
2、充满电后不能维持适配器供电，自动切换至电池。
3、充满电后拔掉适配器，屏幕亮度降低到最低档黑屏。
4、反复插入\拔除适配器，屏幕亮度能够自动升高\降低，但是随着每次插入\拔除，总体的亮度越来越高，即每次插入、拔除后亮度与前一次不一致，均比前一次升高。


对于这些问题，有何解决方案？


下面就是我照猫画虎制作的电量补丁。

说明一下，iasl反编译可能会开启优化，那么数学运算之类的Method将会优化为数学符号，这时候需要修改一下补丁以适应dsdt。
