QUICK SAVE

HI, HOW CAN I DISSABLE TNE QUICK SAVE COMAND. I´VE PROGRAMED TO AUTO SAVE EVERY 10 MIN BUT IT DOES AN AUTOMATIC AUTO SAVE EVERY 2 MIN THAT I DON´T KNOW IF IT REALY IS SAVING MY WORK. IF I DISABLE THE 15 MIN PROGRAMED SAVE, IT STILL DOES THE AUTOMATIC SAVE ENVERY 2 MIN. SOME TOME AGO I HAD THE SAME PROBLEM AND I REMEMBER SOMETHING WAS WRONG. ANY TIP?
