.You must physically remove the processor boards 
from the power supply. Once this assembliy is removed, destroy the processor board and send the 
instrument to a Keysight repair facility. If the repair facility determines that a new processor board 
fixes the problem and the instrument is still under warranty, you will not be charged for the new 
board. If they determine that the failure was caused by something other than the processor board, 
you will be charged for the new board even though the instrument is still under warranty
