Product ID cut down to barcode only. I leave it you to speculate why. Yamicsoft Windows 10 Manager reveals this model should have an illuminated keyboard. It does not. It's clean and it works, but the memory and hard drive are not Lenovo. They are SK hynix. These do not materially change the functionality. The fact that this model lists a backlit keyboard on Lenovo's website, but was rebuilt without one does.
