Today I am finally going to replace the awful chiclet / island style keyboard on my Lenovo Thinkpad T430 with a more traditional 7-row row keyboard from the Lenovo T420. Along the way I discovered the easiest way to install the 7-row keyboard into the T430 which required absolutely no modifications to the keyboard or palmrest. It turns out that this was a very easy modification and, if done right, should only take 15 – 20 mins to complete.
