Back ground :
UP Board was located in inside of instrument. Thus we can’t push power button.
So, we change BIOS setting to boot automatically when 5V power applied.
But randomly UP board didn’t boot even if power was applied.
So, we have to disassemble an instrument and push power button for booting.
1)FAN & LED is normally workable but booting doesn’t proceed (NO BIOS logo) when input power.
2)If we push power button when 1), booting proceed normally.
3)After 2), there was no booting error anymore.
1)BIOS Version : UPC1BMOT / UPC1BMOS / UPC1DM17
2)BIOS setting : Default (State After G3 [S0 State])
3)Test method : 5V Power ON/OFF in a cycle and then monitor booting process (25sec On / 2sec Off)
This is critical problem for the instrument manufacturer....
