Unfortunately if you don't use your keyboard for some time your battery discharge rapidly.
So i decided to insert a power switch and a LED indicator to save battery life.
What you need:
- soldering iron
- electric cable
- little electric switch
- LED (i used 3mm diameter)
- 470 ohm resistance (depending of the type of LED used)
Step 1: Removing screws
Remove them and remember their position (the screws are not all equals)
Step 2: Open keyboard
Remove the cover and rotate carefully the main keyboard (pay attention at the bus connecting the keyboard to the PCB).
You are now able to see a wire connecting the positive pole to the board.
Now it's time to decide where to drill the holes for the switch and the LED. I drill over the trackball because there was enough space and it is a good position to use with your inch.
