Big thanks to a reader named Langolier. His suggestion of trying to pop my broken space bar key back in using this guide worked. I once killed an old Inspiron 3800 keyboard because I didn't know what I was doing. This guide explains what is down there, and how to fix it. It's a big help for anyone having Dell laptop keyboard issue.
Langolier, thanks to you, I don't have to go through the torture of Dell tech support. If you are ever in the Chicago, IL area, I owe you a beer sir.
