I cannot say, "No, absolutely not," but I will say, "Most likely not."
When a laptop keyboard begins to go wonky in any way my first course of action is to replace it. They are more fragile than desktop keyboards and although they don't fail nearly as often as they once did once they begin to misbehave it's usually because something is cracked, broken, etc., that there is no effective way to test for or to fix.
Since the replacement keyboards are generally available at very reasonable cost (and a quick search for your machine finds the low end around $20) and this can be a DIY job it's easier to replace. See YouTube videos about your actual machine or its very close relatives to decide whether you can or want to do it yourself. This task can be anything from simple to hellish depending on how the laptop is actually put together and if you don't decide to do it yourself it should give you some valuable information as to approximately how long the job should take for a professional to do.

. . . the presumption of innocence, while essential in the legal realm, does not mean the elimination of common sense outside it. The willing suspension of disbelief has its limits, or should.
