Malfunctioning keyboard Sony Vaio PCG K415S

Ebay or somewhere similar is your best bet for getting a 'used' and therefore much cheaper replacement. Just type in the make/model of your machine..

Most Keyboards are pretty easy to replace and if your not sure how to do it, run a search on the web or post on here with your specific model etc. If its put together anything like my Sony all you have to do is remove a bit of trim above the keyboard (carefully) and there are 4/6 screws holding the keyboard in place. Remove these and the keyboard just slides out. Then it's just a matter of disconnecting the ribbon and reversing the order to put it all back together.

Good luck, J
