Two (2) for Parts:  Lenovo ThinkPad X1, Intel i5-3427u 1.8ghz 8gb on one.  The other one has a cracked screen and I was unable to read what the bios said.  There is only one keyboard assembly.  It unplugs with a single plug and I used it to test both laptops.  They both seem to boot to the bios okay.  There is are internal batteries but nothing was tested.  They appear to take some kind of solid state drive but they're not included.  They have Windows 8 pro in the bios but I'm guessing you could easily run Windows 10.
