i have problem entering bios on my e531. Computer boots into windows and works just fine. But when i try to enter bios, by pressing F1 at boot I can hear 1 beep(as normal lenovo laptops) and then nothing, just black screen.
Even if i try f12 the same problem.
It seems to that computer enters bios(if i press f10 to save and then enter computer reboots), but i can see only black screen.
tried complete shutdown (**bleep**+power off)->same thing
tried with external display->same thing
tried with bios reset by removing cmos battery->same thing
I have windows 10 installed;tried with advanced boot menu, but it has missing boot to uefi option.
Bios version is the lastest
