How adjusting brightness my laptop acer
Every Laptop has a different label on the keyboard. Usually you need to hold down first the Fn key and pres the label on the keyboard that has a sun icon.
Best of Luck
Brightness is controlled by holding the function key (Fn) and using the left or right arrow. Each time you press an arrow it will change one step, so try several times to change it more...
If it does not change it is at the end of the range.
