I have a Dell Inspiron 2650 laptop onto which, alas, I spilled some coffee. Some of the keys now double up... typing "1234567890" gives "q1w2e3r4tyu7i8o9p0" ("t" and "y" are unaffected), hitting the "[" key usually would give an indeterminate number of "[[[[[[[[[[[[..." and the curson arrow keys respond erractically. I popped the key tops off and q-tipped around there with alcohol which seems to have solved the "[[[[[[[[[..." problem but the other keys are still malfunctioning. Can anyone supply instructions (directions to a diagram?) on how to dig a little deeper into the laptop to access the keyboard circuitry where I might be able to clean up this mess?
