[Guide] Lenovo Y50 (UHD or 1080p) using Clover UEFI

[RehabMan]

It's set as your guide said.
I looked at Lenovo's site, this is the newest version.

EDIT: I think I will downgrade my BIOS to 1.14. I saw the guide said something about 1.14, will try it.

No other ideas.
May be incompatibility with your specific display.

Hi Rehabman i have attched the debug file can you please look and let me know if i have done something wrong.

i have every thing working fine even the display but to get display i have to plugin the charger. once the mac is booted then i can remove the charger and it works fine till the batery is dead. ( about 2 hours backup)

Check for backlight problem by shining light on display.
You might try increasing the backlight level (ioreg shows relatively low setting).
