Fix initial UI state of Battery protection setting
Cherry-pick MR for !384 (merged)
The setting 'Battery protection' in System Settings -> Power Management
-> Advanced Power Settings was always initially shown deactivated and
did not reflect the actual state of the system as given in
/sys/bus/platform/drivers/ideapad_acpi/VPC2004\:00/conservation_mode.
This was fixed so that the initial GUI state reflects the current system
state.
(cherry picked from commit 43446c37)
