Can a jump start damage a home computer?

Just like your home electronics, these solid-state devices can be damaged by voltage spikes, RFI, and back EMF. So let’s start with an examination of how you get voltage spikes when you jumpstart a vehicle.

Can a jumper cable be connected to a dead battery?

Connect the other end of the black (negative) jumper cable to a metal part of the dead car that is unpainted, as far from the battery as the cable will reach. This will ground the circuit and help prevent sparking. Connecting it to the dead battery carries a risk of the battery exploding.
