How to Disable LED Indicators on an HP Laptop. The light-emitting diode indicators, positioned just below your HP laptop monitor, report the status of the computer and its hardware.

You don’t have to suffer bright LEDs. LED status indicators are everywhere—on routers and modems, on laptops while they’re charging, on desktop PC cases, even on wireless chargers.

A red LED, 1.6V, so for 48V that would require 46,4V to be dropped on the resistor. 46,4V * 1mA = 46,4mW of power lost over the resistor (which needs to be 46,4V/1mA=46400Ohm, but lets use 47K for ...

Blue LED light — a common indicator color but one particularly disruptive to sleep — was such an industry breakthrough that the 2014 Nobel Prize in Physics was awarded to physicists Isamu ...

Many people believe that the LED was discovered by US researchers working in the 1960s. In fact, Henry Round at Marconi Labs noted the emission of light from a semiconductor diode 100 years ago ...

The best way to deal with an annoying LED indicator light is to use dimming stickers. With LightDims, you get a sheet of custom-cut stickers in multiple sizes and shapes that you can easily peel ...
