Netbook Keyboard Key "Stuck" but not stuck?

whang2011

Hi everybody,
I';m wondering if you guys can provide any help on my issue (I';ve already Googled for hours today:
I own a Gateway LT2005u netbook. Today my sister said that the [url=http://www.buycheapkeyboard.com/gateway-
laptop-keyboard-c-6.html]Gateway Laptop Keyboard[/url] "s" key wasn';t working and it had to be pressed and held
down harder than usual for it to work. I tried to fix it.
The first thing I did was remove the key and check if there was any dirt, etc. Nothing was causing the problem.
I rebooted the computer just in case. No gas still.
After trying a lot of things I removed the s key again and then removed the brace & little rubber nub (to touch
the key conductor thing) on the keyboard itself under the [url=http://www.buycheapkeyboard.com/gateway-laptop-
keyboard-c-6.html]Gateway Laptop Keyboard[/url] key. Under the brace there';s a little clear plastic covering
that has maybe semiconductor under it to register keystrokes. Pressing it itself (very lightly with a toothpick)
allowed the s key to work but now that doesn';t even work anymore. Yet before when it did work, when I replaced
the key the s key didn';t work.
I did something kind of careless -- I used a toothpick and slightly moved it under the plastic membrane and it
touched the "semiconductor" at which point the s key did work -- reacting on Windows 7 as if the key was held
down. I lifted the plastic membrane a little to make sure that the membrane wasn';t just stuck down on the
conductor. Replacing the key, the s key did work but it still needed to be pressed down hard -- and even after
the fact, the s key produced an s but then acted as if it was held down registering a bunch of s';s. However it
would be interrupted with a keypress or a highlight + cut, etc.
Oh yeah and now it';s not working anymore. Help please?!
* When I say hard I never pressed down on anything HARD Hard just harder than normal.
EDIT: NOW I';m noticing that my "t, a, and maybe o" keys are possibly starting to fail but please don';t let this
really change your reply! The keys are very randomly not registering, nothing serious. HOWEVER
Gateway Laptop Keyboard the "a" key
won';t work with the right shift button pressed, but works with the left one pressed?
