My father once had the idea of taking my shoes to a shoe smith to have the soles repaired. That would have let me get it to 2 years, although unknown to him, I had a few years worth of spares in my closet. Anyway, if you want to make something that is made well last longer than its wearable components, replace them.

I just ordered a new touchpad sticker and keyboard for my 5 year old Thinkpad. I expect to replace the batteries within the next year, but other than that, I expect it to go to 10+ years, even though my previous Dell laptops did not make it past 5 years.
