Sorry, i no longer have the venue.
Wen1, are you still running 10.10? Or have you updated it to the latest OS X release? Because I am having some issues with the internal display not working on 10.10.1 and 10.10.2.. Well if you have updated to the latest OS X version, then do you mind posting your config.plist and dsdt (if you have patched anything that is) also what version of bios are you running? I have it updated to A14.
