Question about Keyboards & Mice
Recently I gave a friend a Sony Vaio laptop (PCG-FRV33). She has used it a total of 5 times since then and now the ''a'' and ''s'' keys don't work. All the other keys function as they are supposed to. She needs to log in at the intro window and the ''a'' is a part of the password.
I have taken the keys off to make sure nothing is impeding them. I even took a look at the the cable that connects the keyboard. I see no evident problems.
I never experienced this when the computer was in my possession so I can't think of anything else to fix the problem. Can anyone shed some light on this?
This is a very common problem. There is a contact circuit beneath all the mechanical parts of each key. If some small spill causes something to get in there it will stop the contact from working. With the keyboard removed, it can be cleaned with a little alcohol and an electrostatic swab. It is also possible that the keyboard switch itself is defective. A replacement board can be found on EBay for $10 to $20. Do not waste money letting Sony repair it. You already know how to remove a keyboard (and for others there are lots of videos on YouTube detailing the simple procedure) you can easily pop in a replacement.

Yes, under each letter and number there is a switch which sends a signal thru the keyboard controller to the CPU to decipher what letter/number was pressed. If the switch on the individual key goes out then it has to be repaired at manufacturers or PC repair.
Don't forget to rate this solution.
