ahalol Posted November 6, 2019 Share Posted November 6, 2019 Hello Jake! I recently acquired a E7470 but with the 6650U processor. I saw in this thread you provided a config and DSDT for 6650U but I can no longer download the file. Can you upload that one again? Thank you!

Administrators Hervé Posted November 6, 2019 Administrators Share Posted November 6, 2019 Follow the E7x70 guide available in our Guides section. CPU model is irrelevant. Link to comment Share on other sites More sharing options...
ahalol Posted November 8, 2019 Author Share Posted November 8, 2019 Thank you for the reply. The GPU of the 6650U is Iris 540, shoudn't there be a problem since the guide specified the GPU to be HD520. Also could you please tell me what BIOS should I use. I saw in the post that the bios version specified lastly was 1.17.5, yet the latest BIOS from DELL is 1.22.8. Which one should i use? Link to comment Share on other sites More sharing options...

ahalol Posted November 16, 2019 Author Share Posted November 16, 2019 I installed Catalina recently but I found the wallpaper is glitched. Is that normal? Is there a way I can fix it? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted November 16, 2019 Moderators Share Posted November 16, 2019 Not 100% sure what you mean...do you have full graphics acceleration? Post debug file Link to comment Share on other sites More sharing options...
ahalol Posted November 16, 2019 Author Share Posted November 16, 2019 I used Hackintool to fix the framebuffer to be my iris 540. The attached is my debug. Do you think all is normal? debug_25350.zip Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted November 16, 2019 Moderators Share Posted November 16, 2019 Seems you have graphics acceleration but you lost the DP port according to the IOReg file. You only have the internal LCD and 1 HDMI port. Did the wallpaper glitched with your new Config file or mine? With my config file, does graphics not show HD540? I see you have added DW1820a wifi in your Config file, does it work? Last I tested it, my system hang after 10 - 15 minutes of usage. Link to comment Share on other sites More sharing options...
ahalol Posted November 16, 2019 Author Share Posted November 16, 2019 With this new config, the wallpaper does not glitch. With your config, it shows HD540 but everytime the wallpaper changes, the system glitches. How can i add back the DP support? The DW1820a works in my case. I didn't have to change the pins.

Moderators Jake Lo Posted November 17, 2019 Moderators Share Posted November 17, 2019 Have you tested if both HDMI and DP are working before trying anything Link to comment Share on other sites More sharing options...
