This worked perfectly for a couple of my IBM Lenovo R61s. It was spot on except in step 3 you need to remove both screws by the red circles in order to the get inside bezel off, for the R61 anyway. Thanks for the great tutorial!

Excellent guide! It took me less than 1 hour to complete all the steps, and get my R61 up and running again! Thanks a lot
