I checked computer sites for reviews of the best business laptops.  The Lenovo ThinkPad was normally at the top or near the top of the ratings.  The solid state drive is very fast and I also added additional memory since I use this computer for business.I use an external monitor and one comment I have is that when the unit goes to sleep I need to raise the closed lid to access the fingerprint reader.  It would be nice if there was another option to resume without raising and lowering the lid.  I have Windows 10 configured to do nothing when I close the lid.
