My 770 series 3 won't turn on with the power switch at the console anymore, just started. I now have to go under the machine base where the control computer is and push the on button every time. I was told on another forum I need to change the battery in the mother board in the computer.
Has anybody had this issue and if so how do you get to the mother board. I assume I need to take the cover off the computer but is there any tips for me. Thanks
