Why does the mouse on my company 6510b acts like if it has a mind of i

Hi @lonelyone973 ,

The touchpad in your laptop may be failing or perhaps has a loose connection.

Here’s a link to the service manual for your laptop.

The touchpad is part of the top cover assembly.

Scroll to the bottom of p.79 to view the necessary pre-requisite steps and then the procedure to remove the top cover so that access to the touchpad (and touchpad connector cable) is possible.

If the connection seems OK the part number for the top cover is also shown at the bottom of p.79.

Search online using the part number only to find suppliers of the part.

In the meantime consider connecting a USB mouse to use in your laptop until it has been repaired.
