Question: the spacebar, enter and backspace keys are not working on my laptop - how do I fix this? We've used the Dell SupportAssist functions on the laptop, running diagnostic checks, and there's nothing wrong with the keyboard. The rest of the keys work fine and, intermittently, these three keys start working again. Nothing has been spilt on the keyboard. Some others have had this issue of these specific three keys not working and in their cases, it turned out to be a bug. How do I fix it in my case?
