Teen electrocuted while working on unplugged computer

Discharging a capacitor involves placing a load across its terminals so that the stored energy is dissipated safely. The load is typically a wirewound power resistor, although a mains light bulb can also be used. If a voltmeter is connected in parallel, you can also see the residual voltage reduce until it is close to zero (although it will probably never actually be exactly zero).

Great advice. I'm an EE and anyone can become complacent. I remember as a young eng technicians watching my moves when working in the power supply industry.

Maybe a safety sticky under hardware Brink?

Hum great idea MJF and yep I agree with dwarf anything will do even an olf heater and I have often thought that old PSU's could be left with fans and HDD's hooked up until the power runs out ? I might just try that idea.

That's where the big capacitors are.
