Welcome to Justanswer.com, my name is ***** ***** I will do my best to assist you.
To get started, I need to know what type of computer you are using, a Windows XP, Vista, Windows 7, Windows 8, Windows 10 or a Mac.
If its a Mac, please check the OSX version as follows, Click the apple sign at the top left of your screen, then click about this mac. And then where it says version, send that to me as a reply.
Also, whats the name brand and model of your laptop?
And , how long ago did this issue start to occur, or when was the last time your cursor worked normally?
Thank you for your response,
