I'm sorry about the issue. Do you mean the mousepad / touchpad is not working?
When did this issue first occur?
Is the keyboard currently working fine?
Does your laptop have Windows 7, or 8 or 10?
Can you please check at the back / bottom of your Toshiba Satellite Radius 11 laptop for the full model, such as L15W-B1208 or L15W-B1302?
Can you press at the same time the two keys Fn and F5 on the laptop's keyboard to see if it is able to enable / disable the mouse / cursor?
Do you have a USB mouse? If yes, can you connect it to the laptop, and see if the USB mouse works temporarily on the laptop.
