Max’s fascination with my laptop

I don’t know what it is with Max and his fascination with my laptop.  He likes to jump and sit on it.  It doesn’t matter whether the laptop is closed or opened.  When it’s opened and I’m not around, he will sit on the keyboard.  But I would know he had been messing around the keyboard because I will see this endless line of “zzzzzzzzzzzzzzzzzzzzzzzzzzz” on the internet browser, the alphabets that will appear being whichever ones he happens to step on.
