              Both options to enable/disable the Charging Threshold service, the default  thresh‐
              old  value  is 95%.  To custom the value, use `batterycm-switcher config` and go to
              the CUSTOMS section.

              Both options to enable/disable the systemd service, which Batterycm-Switcher  Func‐
              tion  Key  Backend  Service.   An  backend service capture the function key opening
              Lenovo Vantage in Windows, the keycode depending on your hardware.

              This  option  to  show  current version of batterycm-switcher, program name will be
              shown as the core module name of batterycm-switcher.

NOTES
       While no options special, batterycm will switch the conservation mode according to current
       mode.  If current mode is on, turning off, otherwise turning on.

       It's  necessary  to  know  that  `batterycm-charger.service`  is conflict with `batterycm-
       switcher.service` and other commands.  So I highly NOT recommend  use  both  at  the  same
       time.

       Don't  reporting  it as a bug if you don't have the `ideapad_laptop` driver.  Use `lsmod |
       grep ideapad_laptop` to have a try, no any reasons to directly uninstall this utility.
