I just installed my second new S1200BTLRM motherboard. I am interested to find out what is the reason for blinking amber status led. No other led are on/off/blinking. I didn't have this kind of result with my first motherboard.
I have upgraded firmwares to the latest. I also run sysinfo-tool which informed the following:
Boot Code: 02.02.00.049
ME Health Status: PSU MONITORING SERVICE ERROR
ME Health Status [Extended Information]: PROBLEM WITH PSU NO :1
BIOS error page didn't inform anything. Although I changed the psu, but the blinking didn't stop. The both PSU are conformable to ATX standard.
