2017-07-01, 12:23 PM

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.

Its a hardware problem of some description. A technician would need to assess it. If its not even getting close to the boot process.

Call Lenovo Tech Support who may advise you on something.
