Hi guys,

I got an old computer from a press which needs a new programmable battery since it gives an error message about CMOS. I need to replace the old one but must also transfer its program.

IC: ST M48T86

Can this be done with GQ-4x?

BR,
George

You would need to look at the datasheet.

You are lucky no critical data like calibrations was lost with the dead battery.



if that was the case we would need a donor board to read the chip that was still operational. but how would we do that? I think we did not clarify this part :)

thank you, I will look into this further.
