I was told that stickykeys has to be programmed – and has a whole voice thing going on. It’s not that. I haven’t “enabled” it by mistake, according to him. He still thinks there is a physical problem with the laptops keyboard and suggests connecting a regular keyboard to it to check this out – and for use in general.
Thanks for the answer. I am still open to suggestions and ideas.

I am not a computer maven, but this reminded me of something I had to get used to when I started using a laptop with a mouse pad under the spacebar….....

I had the bad habit of dragging my thumbs across the mousepad and it would do what you are talking about. The sensitivity setting for the mouse pad can be lowered sometimes.

Are you hitting the mousepad accidentally with your thumbs? When I first started doing this, I was completely oblivious to what I was doing and thought my computer was possessed or something. Really freaked me out.

Flip the PC over and check to see that the screws are tight. If they are, I vote for a particle of something under a key.
Are you willing to try something a little risky? Do you have a vacuum cleaner with a crevice tool? If the answer is “Yes” to both then….
Befroe turning the vacuum on practice sliding the tool across the keyboard, never lifting! Remain in contact the whole time! Got it? Practice. Practice going back anforth. across the space bar and mouse keys . Practice. Never lift off the keys!!!

Now rest the crevice tool on the edge of the keyboard, turn it on and do it .

Why can’t you lift the crevice tool? Because it can suck the keys right off your keyboard if you do.
I’ve preformed this procedure at least 100 times and only lost one key – and that was very early in my career.
I am now qualified to do prostates, too.

I turned mine upside down and gently tapped on the bottom. I was surprised at what came out of the keys. Works great, now.

@cazzie‘s description is what I was thinking too.
I don’t know how people don’t accidentally activate the touchpad all the time.
I am not a big fan of touchpads at least for this reason, I like the Lenovo hula-point much more. You might be able to disable the touchpad in BIOS settings and just use the hula-point.
...Although you’ve had this for 18 months so it’s surprising this is a new phenomenon.

Update – and thanks everyone.

I have decided (with advice) the problem is the keyboard – after a professional cleaning. I have purchased a plain old USB keyboard and am now typing away happily with it. Truth is I never liked the feeling of the laptop’s keyboard.
