Laptop touchpad is not working properly while charging

[Mermaid]

I have a strange problem with my Sony vaio Laptop. When I plugged in the AC charger, the touchpad / mouse does not work properly. Sometimes it moves and sometimes not even though I have moved and touched the touchpad. When I disconnect the AC charger, the touchpad works perfectly fine.

Can anyone give me advice on this?

thanks in advance
