Welcome in lenovo community,
Please try to,
Open the device manager >> Right click the graphic driver >> Properties >> Select Driver from the upper tabs >> click Roll back driver.
If it did not help, please try to
uninstall the graphic driver from the device manager then restart after that right click the graphic driver from the device manager and choose Update driver software.

I tried both but without results. I also boot it with Ubuntu but almost the same. even if i enter to bios setup there is no backlight. Is there any way to reset bios to default bios factory? I have the v1.21 (the last one).
