DSDT Acer Aspire 7741G

Recommended Posts

Hello all,


Details my laptop:

Acer Aspire 7741G-374G50Mnsk

17.3" LED CineCrystal (Max. resolution 1600x900)

Ati Mobility HD5650


I need your help and advice. I have done the installation 10.7.2 Lion by DVD iAtkos l2. Everything works fine, but LVDS is not detected.


I've changed DisplayProductID-717 with my EDID file generated, but it fails.

Also, I made many tests changing "Custom Ati kexts" but it still fails.


I get that LVDS is detected by these customs ati, but it displays four screens in LVDS:


Test01: 04 00 00 00 14 00 00 00 00 01 00 00 01 02 01 07

Test02: 04 00 00 00 14 00 00 00 00 01 00 00 02 02 01 07


By these customs ati, i get that LVDS is not detected and LVDS shows black screen:


Test03: 02 00 00 00 40 00 00 00 09 01 00 00 10 00 00 07

Test04: 02 00 00 00 40 00 00 00 09 01 00 00 00 00 00 07


All the other tests, i get that LVDS is not detected and LVDS shows stripes.


My question is:

Can i fix this problem by applying the DSDT 7741G?


Thanks and regards.
