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)

Problem reporting files must represent the problem scenario (capture ioreg/etc with in the scenario internal screen is not working).

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

I'm not sure what you mean. You will need to clarify.

when i turn on the system without Charger the display is black but the backlight works i can see the white light from dislay. if i press F1 and then F3 i can see the display for just a second
