The pen touch does not respond

  1. Check whether the driver has been successfully installed. Try to reinstall the driver and restart. 

  2. Check whether the digital pen nib is set as "enabled". If not, please reset it as "enabled". 

 It takes too long for the pen touch to  respond 

  1. The CPU is occupied by programs or too many processes are running. Try to close applications
      which are not used temporarily.  

  2. There is debris on the screen which affects the operation. Try to clean the screen of the pen
      computer.
