Lenovo M73 - a nice little computer and have one from another seller so have set expectations.Started (but not initial push - should have been sign).  Spent the requisite time to set up Win10, load programs for a worked, etc - several hours worth.  Windows updates... Hmm not restarting as it should.  Changed power (button) settings, updated bios - but issues with restart/sleep/hibernate.  CMOS?  who knows, but that is a chore to replace.  Doesn't really make sense would be that as powered and not date issues.  Ultimately this problem should have been discovered on going over the computer - probably the hardware with the button, connection with motherboard or similar.  I have need of computer now, not back and forth with seller.  Was considering replacing, but when going through motions of returning, I find I have to pay for shipping back.  Considerable insult considering the time (read: $$$) put into the machine for an issue that should have been discovered prior to it being shipped to me in first place.
