This is a Lenovo B570 with Intel Core I5 processor,  offered for spares or repair.  It is complete with the exception of having no hard drive. 

Was working with Win10 when it was last complete but now no Windows because no hard drive.  Now boots as shown in 1st photo.  There is no guarantee that the machine will work and hence selling as for 'spares or repair.

Supplied with two batteries, mains unit, and booklets. The second battery is believed to be serviceable but the BIOS,  or maybe other change made by Lenovo,  appears to cause it not to work with this computer.This was also previously the case with the first battery, but that one is now working (again - no guarantees).
