Name plate data for many electronic devices will be inaccurate. Your value sounds low for a laptop.

You definitely should not divide by work hours - the form requires the rated power - which is the value on the name plate. You might check the technical specification for the product online.

I generally do not see watt hours on the name plate. There is usually a watt value or sometimes volts and amps for larger equipment.
