Q: The keypad is not registering with my macbook pro - changed batteries but still not working.  Bluetooth says it is connected.  Suggestions please.

Hello:

Try resetting the SMC.

Your MBP sees the Bluetooth keyboard but won't pair with it probably because the keyboard is pairing with another computer or device nearby. If you had previously paired the same keyboard with another device, go to the other computer or device and either unpair it or have the device "forget" the keyboard. Then you will be able to pair the keyboard with your MBP.
