I have a LG monitor and i have had this issue twice already, i dont know what kind it is it had a clear bar thing thats kinda curve shaped that goes all the way across and to the right in the middle is a bump where you slide it there to turn it on and i have a nice e9220y i think thats it with widows 7. after it being on for a while (maybe or maybe not) the screen will say DSUB(outuput/input its connected to) "POWER SAVING MODE" and no matter what i do i cant get it out of it and when i try using keyboard or mouse it is nonresponsive, i checked the keyboard and noticed when i hit numlock or caps lock the little light doesnt light up. My dad put a password on it so i dont want to turn it off or ill have to wait for him to turn it back on D: so plz give me solution
