Bios black screen with white dash in the corner

My laptop is Lenovo B50-30 20382

I tried to enter the bios (fn+f2) but this time didn t work, i tried the next time and the same result

I can use the windows with no problem

I don t know what to do, i really need to use the bios, i tried advanced start to enter in uefi settings but nothing. I searched through many forums but i reallt find one solution. To reset the bios by removing the CMOS battery from the motherboard. 

Is there any solution that i can do without removing the cmos battery?

Please help me

Hello LONEWOLF4

Thanks for using the Lenovo forums.

Try to see if you have fast boot enabled:

Disable the fast startup option in Control Panel -> Hardware and Sound -> Power Options -> Choose what the power buttons do

 

Hope this helps, let us know how you get on.

Nope. I tried that before. It s been a while since i tried to enter in bios. But nothing. I don t think that is any solution... and know what. Lenovo support doesn t help you if your warranty it s dead (i have this laptop from 2014 and i didn t lose the warranty, he just expired).

-hmmm. We do good products, why we should do good support also? Neh we will stick with good products and   support. Couse why not?!

In that case, as you say if you can access Windows, you could try to start a recovery from there.

 

You can follow the manual on how to perform a recovery:

Hope this helps, let us know how you get on.

Re: Bios black screen with white dash in the corner

so, i've done some research and it seems like there was an available update for my bios (from 2015 *-*) and after i updated it with lenovo's bios update tool, it works.
