I do not have other ram and i dont have hard drive i have ssd stick looking and its just doesent go bios its just says no hard drive connected
So it does show something, since something has to say "no hard drive connected" you said it just shows a black screen and can't get to BIOS. Try another drive. Did you already contact Lenovo support if system is in warranty? You may want to provide some details about exactly what you see when you turn it on, does it try to boot then fails and tell you no drive detected?
