CHAPTER 5 – TROUBLESHOOTING YOUR SMART BOARD INTERACTIVE 
WHITEBOARD

Flowchart 3: Ready Light Red

A red Ready light indicates that your interactive whiteboard is receiving power but isn’t 
communicating with your computer. Pen tray LEDs don’t turn on and the screen isn’t 
responsive to touch.

Disconnect and then reconnect the USB cable at both ends to 
reset your interactive whiteboard and re-establish the 
connection.

If the Ready light changed from green to red while your 
computer was running, the computer could’ve become 
unresponsive. Restart your computer.

A powered USB hub or extender could’ve failed or become 
disconnected from your computer. Check the connections 
or replace the failed component.

An alternating red/green light could indicate that your computer 
is running too many applications or doesn’t meet minimum 
hardware and software requirements. Reduce the load on your 
computer by closing unnecessary applications, or replace it 
with a more powerful computer.

Make sure that the operating system has all USB HID drivers 
and current upgrades installed.
