I have Dell Model AA20031 Power Supply for Dell Laptop and I like to
reduce it to 13V, 1Am so I can use it on my Canon BJC-250. I have
opened the pack and I like to know how to do it. Thanks

Use an LM317 or LM317K on a heatsink to get rid of the 7W it dissipates.
You'll need some resistors to set the output voltage and some capacitors to
keep it stable. See the data*** for it.
