I have just purchase the Lenovo Thinkpad W540. But currently we have issue with the built-in display. The phenomenon as below:
1. When power on - The built in display can show welcome screen, and even enter the BIOS setup screen. If let it boot normally, the built-in screen then off.
2. When booted to Windows 8. The built in display still off. If I connect an external display to the VGA connector, the external display work well. Checked the display option see that it is "clone display --> Built in + External Display".
I suspect that there is some thing wrong with the display setting that I don't know how to adjust to get the built-in display works properly.
Note that I can see the build in display backlighting but there is no picture shown when in screen cloning setup.
Can some one help on this ?
