Yes it is "self programmable". After replace i use charger which goes bad in ID pin. with another charger, all works -
Found this
"The Nuvoton NPCE586HA2MX is a programmable keyboard controller (KBC) used in various motherboards, including models DA0X8CMB6E0 REV E and DA0X81MB6E0 Rev E. It is noted that the system is pre-programmed during production, eliminating the need for additional programming after replacement."
So it is programmed by bios?Last edited by ktmmotocross; Yesterday, 01:00 AM.Leave a comment:
