If you do not save the values ​​is that the battery is not working, which can mean one of five things: 
 
- The battery is installed 
- The battery does not work 
- The board is faulty 
- Some boards have a button to clear the cmos. Just like it has been pressed. 
- Other plates allow Removal removing cmos jumpers. See if the jumper has been moved. 
 
That's what I can think of right now.
