I had this same problem and just now solved it. Either restart or turn off your PC. As your PC is rebooting or starting you will see a black screen with F2=startup
etc.
It may say F6 = setup, in any case immediately hit or press down that F key. A screen will pop up. Find the system time and change it. Mine said on the bottom Change space + -
which means make sure whatever you want to change is selected (use the arrow up or arrow down key) and then press first the space bar--don't let up--and then the + or minus key and it increases or decreases your time. Remember it is in military time so that 16:00 means 12:00
It is that simple!! Now you have changed your PC to the correct daylight savings time!
