Chosen Solution
when i need to charge keyboard battery. SONY tap 11 is design method by close the keyboard and tablet together. like this but sometime i need to use keyboard for longtime. until battery gone. this method is not work for me. i want to find some idea for make a cable port to connect it. If i can connect it by three wire. Will the computer is work and keyboard still charging? or If i have to know the voltage all of 3 pin and i can connect it with converted voltage battery. can i make a standalone keyboard charger?
aparently not properly desing from SONY but i´m experimenting with some homemade conections, i haven´t found any other solution yet
