Two weeks ago something got under my space key making it resistant to being fully pushed down. I managed to remove that piece by taking the key off and vacuuming gently in the area but the rest of my keyboard has a lot of resistance, and the space key itself is still not registering all the time, especially toward the right side where I usually hit it. What could be going on? In particular, how can a particle getting under the space key make the whole keyboard become too "springy"? I really want to avoid sending this in because it's my only computer and I have several deadlines to adhere to for work.
