How do I repair a Key (the letter "I"...an important vowel) that has come loose on my Toshiba Laptop Keyboard? It doesn't look like it should be glued because the base seems to have a sort of "riser" or part that rises and falls with the key...the glue might stick this and make things worse. Al least that's what it looks like. Any suggestions? How about buying Dell Laptop Keyboard or Lenovo Laptop Keyboard?
