Hello All,

Having trouble with a Dell Precision T7810 motherboard booting.

Question: With the motherboard sitting on the bench with a good 3.3 volt CMOS battery in the board,,if i check voltage at pin #8 of the bios chip,,,shoundn't i be seeing VCC / 3.3 volts?

Does power supply have to be plugged into the board to obtain the 3.3 volts at pin #8.
Am showing my stupidity,,,,,which I can do very easily. :)

TIA
