我在没有电源的情况下使用 Debian 安装程序对系统进行了分析。尽管显示电池电量充足，但笔记本电脑将在没有电源的情况下 7.5 分钟后关闭。所以问题很可能是硬件，但我不明白是哪一部分。我认为问题不是操作系统问题，因为我可以用实时 USB 重现它。
其他详情
我的静态功耗平均为 24 W ( awk '{print $1*10^-6 " W"}' /sys/class/power_supply/BAT0/power_now)，应该没问题。所以应该还有其他原因导致电池耗尽。笔记本电脑现在可以持续大约 7.5 分钟。

操作系统：Debian 8.5
LK：4.7 向后移植
硬件：华硕 Zenbook UX303UA（大约 3 个月大，从英国亚马逊公司购买的新产品，因此仍然有保修）
答案1
...我的平均功耗在休息时为 24 W...
这是你的起点！
我的笔记本电脑闲置时的功耗大约为 3W...
编辑：以我诚实的观点，你必须调查为什么笔记本电脑如此精力充沛的;尝试使用使用较新内核的发行版来测试笔记本电脑，因为机器确实很新，因此无法完全支持硬件
答案2
DX 电池故障。我把电脑拿到服务台，因为电池最后只用了0秒。所以电池失效了。我认为关于这件事的最大迹象是对实时 Linux 的测试，观察到电池一次只能持续 7.5 分钟，最后是 0 秒。
一切都在保修范围内。我认为这些亚马逊/... 折扣电脑有时电池故障风险更高；如果能获得一些相关统计数据就好了。但是，这样做是有道理的。如果怀疑零件有缺陷，请尽快售出，从而降低价格。
