Problem
I have a laptop that says it needs a 19V 3.42A power supply. I have a Dell 20V 4.51A power supply. Can I use this power supply with my laptop, or will it destroy the machine?

Low Risk
Electronic equipment is typically capable of handling voltages of a nearly 20% difference. As for the current, the laptop will only draw what it needs. If the PS was lower I'd worry, as long as it's rated higher than needed by the laptop you're ok.
