Pop OS / Dell XPS 9310 -暂停后一夜耗尽电池

Question

我的笔记本电脑挂在盖子上成功地关闭了，但如果我不让它在一夜之间插入，电池在早上就会耗尽。

我包括了刚才运行的一个短暂停日志。我可以在一夜之间把它挂起来，然后再看日志，但是这里有什么可疑的东西吗？我验证了所有与挂起相关的目标都是通过sudo systemctl status sleep.target suspend.target hibernate.target hybrid-sleep.target加载的。

该系统上的硬件只支持s2idle睡眠，而不支持deep睡眠，以降低能耗(这里详细介绍了https://www.kernel.org/doc/Documentation/power/states.txt中不同的睡眠状态)。

pop-os:$~ sudo cat /sys/power/mem_sleep 
[s2idle]

我找到了这个线程：https://www.dell.com/community/XPS/XPS-13-9310-Ubuntu-deep-sleep-missing/td-p/7734008，它建议通过Dell将磁盘管理从RAID (戴尔的默认)更改为AHCI。

到目前为止，这已经成功地解决了！我一夜之间只损失了10%的电池，可以在没有充电的情况下空转3天。

(在此之前，我确实尝试通过System76 https://support.system76.com/articles/enable-hibernation/的这些说明启用hibernate。这并不是很好，因为Killer wifi驱动程序不会从hibernate加载唤醒。)

挂起(考虑混合挂起)，将机器的状态存储在交换空间中，并通过RAM调用挂起(也称为睡眠)。这导致了权力的最低限度的使用。

这样做的原因:从冬眠中醒来比从睡眠中醒来要慢。因此，为了确保系统状态不丢失，机器的状态存储在交换空间中，并调用使用最小功率且不关闭机器的睡眠。机器的状态存储在RAM中。如果电池不死，从内存中醒来会更快。阅读更多：https://wiki.archlinux.org/title/Power_management/Suspend_and_hibernate

如果你想你的电池不死或流失，切换你的盖子关闭行动从睡眠/暂停到冬眠。Hibernate的功耗为零。按照下面提到的步骤。

$ grep HandleLidSwitch /etc/systemd/logind.conf 
HandleLidSwitch=suspend

如果该行被注释，请删除"#“并将选项更改为hibernate，从而取消注释。

HandleLidSwitch=hibernate

如果您是Linux新手，请使用gedit命令编辑该文件。

sudo gedit /etc/systemd/logind.conf
