In the lower right corner I have blue small airplane. Looks like some other figures grayed out- not able to switch between them. Not an icone of notifications- it is an image on a screen. What does it means? Thank you.
Your mobo is ASUS and as Astralv mentioned above, it is part of the AI Suite that comes with certain ASUS boards. Go into your programs and have a look at it. You can increase performance with it (Air plane is High Performance mode), decrease it and save power, etc
