I have an old IBM computer power supply; works on AC or 12 V DC. Output is 16.78 VDC. I would like to reduce the output to 15 VDC, to run a newer Toshiba computer from 12VDC in an RV. Can I do this with a resistor? If so how do I calculate the value? Hoping make a short cable with a socket for the old plug - resistor - new plug. Is this a way to go?
