I have a Lenovo laptop. Unfortunately, the mouse jerks something. So when moving on the notepad the mouse just moves sometimes it stops, what can I do?

Do you use a mouse or do you use the pointer over a touchpad?

It does not matter if you jerk it with your mouse pointer or external mouse

How old is the laptop? And how much is the main memory at full capacity?

About 5 years and he is busy about 30%
