Does anyone know if a novice armed with just a few Phillips
screwdrivers can easily replace the power supply of an HP dv1040us
laptop?

Beware of novices bearing screwdrivers.

Where would I purchase such power supply?

eBay:

Apparently mine has died and the laptop does not boot up. I cannot
hear the inside fans turning nor the hard drive spinning.

Power supplies will die, but I've seen more HP laptops with broken
power connectors and power supplies with broken power plugs. That
style of plug has a very fine wire in the center of the cable. If you
bend the cable 90 degrees where it enters the plug, it will eventually
break. If that happens, you can still run the laptop with the power
supply plugged in, but it will not charge the battery.

You might want to take a VOM (volt-ohms-guesser) and measure the
voltage coming out of the power supply (without the laptop). It
should be about 18.5 VDC. If that's what you're seeing, then look for
a problem elsewhere.

Good luck.
