After upgrading to Dell SA v 3.2.2 I've noticed:

- CPU is quite high, around 12% all the time. Sometimes I can hear my laptop fan because of Dell SA running.

- An urgent update has been found "Dell Inspiron 5370 and Vostro 5370/5471 System BIOS". I've chosen to install it, but displays "downloading" indefinitely. See screenshot:

Thanks for your help.
