Hello Joonyer and welcome to Bleepingcomputer.
Laptops usually have support pages from their vendor addressing the touchpad issue.
I could point you to a link for any laptop, but prefer to link Bleepingcomputer members to the support documents meant primarily for their specific laptop make and model number.
I realize you have a Toshiba brand laptop, but the model number works wonders in obtaining support documents.
In the meantime however, I am going to post a link to a web site that specializes in free Toshiba laptop repair documents for the home users.http://www.irisvista.com/tech/
The web site I linked you to above is something you should bookmark for future reference even if you do not plan to use its documents now.
