Hi, 2 days ago I spilled a whole glass of water on my laptop, a Dell inspiron 1520.  I quickly turned it off, turned it upside down and most poured out, I then soaked up some with a paper towel, then blew more out with an air compresser.  I then took the battery out and let it sit upside down for 3 hours.  I turned it on and it was working normal, but I wanted to check if there was anything else I could do.

I was watching a video about what to do in that situation and it told me to remove keys in order to see if there's any moisture under them.  I took off my spacebar and I could not get it back on.  All the pieces seemed to be in the right spot, but it would not snap on.  I left it for my dad and he got the spacebar on, but now it is not stable.  Before I could press down on any spot and it would make a space, now I need to aim for the middle, otherwise it just doesn't make a space.  It's becoming very annoying to try to type with it because it doesn't make a space every now and then. 

There's only one thing that I think he might of done wrong.  There are 2 L-shaped bars running the length of the underside of the spacebar.  They can be turned upward, and 1 was when I first took off the spacebar.  Could this be the problem?  And any suggestions on how to put the spacebar back on?
