While some netbook makers *cough* *MSI* *cough* seem to feel the need to throw so many status LEDs on their case that it’s tough to tell what any individual blinking light means at a glance, others have taken a much simpler approach. The Dell Inspiron Mini 9, for example, has just two status lights: One for power, and another for battery.
One member of the My Dell Mini forums decided to add a “hard drive activity” indicator. He managed to do this without replacing either the low battery indicator or the power LED by placing a new blue LED near the battery light. So when the SSD is in use (the Dell Mini doesn’t actually have a hard drive, but rather a solid state disk), the blue light glows. When your battery light gets below 10%, it will blink orange.
You can watch a video of the new LED in action below.
