Title:
[HP Spectre x360 - 15-df0008nc] Battery is drained in the laptop sleep
mode
Status in linux package in Ubuntu:
Incomplete
Bug description:
[HP Spectre x360 - 15-df0008nc] Battery is significantly drained in
the laptop sleep mode. Over the night the fully charged laptop battery
will get empty while kept the laptop in sleep mode. The symptoms are
the same with or without connected USB-C dock.
As a workaround also it is not possible to enable deep sleep.
Full laptop specification is here:
https://support.hp.com/za-en/document/c06200426
Enabling deep sleep results into failure:
$ sudo echo deep > /sys/power/mem_sleep
bash: /sys/power/mem_sleep: Permission denied.
Additionally also not possible to enable deep sleep by updating grub
loader.
# editing /etc/default/grub
# Adding
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash mem_sleep_default=deep"
sudo update-grub
# reboot laptop and still gets s2idle
$ cat /sys/power/mem_sleep
[s2idle]
