Hello, my wireless keyboard no longer turns on. I have tried charging it, but even though the LED light shows the board is charging, switching the keyboard on doesn't have any result. Pressing keys or using the track pad does nothing. The caps lock button does not light up. Plugging the keyboard into the laptop using the USB-A to microUSB cord doesn't change anything either. What can I do to repair my Vaio Z Canvas keyboard? Can I replace it if it cannot be repaired? Will Vaio help me with this?
