Administrators Hervé Posted March 27, 2020 Administrators Share Posted March 27, 2020 NVS 5200M is Fermi and has no support beyond El Capitan so you need to disable it. If you browse through the numerous threads and posts in relation to those E6x30 models with nVidia dGPU, you'll find the SSDT table required to disable it. Once dGPU is disabled, you'll find your battery life improves. Link to comment Share on other sites More sharing options...
lucahappy Posted March 27, 2020 Author Share Posted March 27, 2020 ok thanks Hervé! I'll see for this SSDT. Please, if you have link send me and tell me please if I have only to put it into EFI-CLOVER-ACPI-Patched Folder. Thanks again Link to comment Share on other sites More sharing options...
lucahappy Posted March 27, 2020 Author Share Posted March 27, 2020 Hervé can I disable NV5200 with boot flag "nv_disable=1" in Clover configuration boot flag? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted March 27, 2020 Moderators Share Posted March 27, 2020 try both. If not working, I'll send you the SSDT to disable nv_disable=1 -wegnoegpu Link to comment Share on other sites More sharing options...
lucahappy Posted March 27, 2020 Author Share Posted March 27, 2020 Jake Lo, dont work. I still see nvs 5200 in system info Link to comment Share on other sites More sharing options...
Administrators Hervé Posted March 27, 2020 Administrators Share Posted March 27, 2020 nv_disable boot parameter does not actually disable the dGPU like a DSDT patch or a dedicated SSDT will (by powering it off), it just signals the OS to ignore it and not load drivers so that OS X/macOS will run graphics in VESA mode only. Please use the forum Search tool/facility to seek the SSDT table that disables NVS 5200M dGPU in Latitude E6x30 laptops. Link to comment Share on other sites More sharing options...
lucahappy Posted March 27, 2020 Author Share Posted March 27, 2020 ok Hervé...I'll waiting for a SSDT then because I don't know where I can get it ....I search into post but can't see it Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted March 27, 2020 Moderators Share Posted March 27, 2020 Looks like you already have all the files needed in the EFI you attached. You just need to boot with DSDT1.aml So rename DSDT.aml to something meaningful like DSDT-Optimus.aml and rename DSDT1.aml to DSDT.aml Reboot. It should have the nvidia disabled.

lucahappy Posted March 27, 2020 Author Share Posted March 27, 2020 aaah ok! so good! I try it now and it work fine....I think now I have only to check battery duration. but in your opinion which version would be better to have on my dell e6430? EDIT: I try to change brightness with Fn + up down keys and don't work after DSDT change Link to comment Share on other sites More sharing options...
