Everybody obviously works on a powered on laptop, with fully charged capacitors. With those capacitor delivering at leat 100mA to your heart for good measure.

It's like when people work on their car, they do it at highway speed, using a nacelle precariously balanced under the car, with the front wheels propped up on dollies for access.

And I'm sure that continuing that tradition into the laptop LCD era is similarly due to safety and not profit.

...Are we talking about CRTs from like 20 years ago? What does that have to do with laptops?
