Recently my lenovo laptop z50-70 start blocking on black screen before lenovo logo appears on start up with led light on. It lastes from 15 minutes to even 2 hours before lenovo lego appears and laptop starts and works smoothly with no problems.
Now it is blocked on black screen and can t proceed to lenovo logo. I can t acces bios menu.
I tried bios reset. no effect.
I updated the bios to the last version. no effect.
