Running Ubuntu on Lenovo Laptops

Thu Mar 27 08:05:51 UTC 2014

I have four laptops running XP Pro.  Now that support for XP Pro is 
finishing I am consideri ng whether to go back to using Ubuntu which I 
used on my old desktops. The Lenovo models are X61s, T400, W500 and 
X201.  Will they run ubuntu? If so is changing the operating system 
problem?  I have all of the laptops backed up to external hard drives.
