Blender on X series Thinkpad 220x and back
 

Im not sure what think pad from the xseries (220x and going back) would fit the specifications for blender: https://www.blender.org/download/requirements/ my I please get a more expert opinion ? Many thanks!

you can download blenders binary and see if it works or not, if you already have that laptop.

Or look up the specks on a x-xxx xseries and match it up with Blender specs to see if they match. I do not know what more me could do. Outside of buying one and doing just what you need to do to find out the same thing.
