mattj88 Posted February 8, 2018 Share Posted February 8, 2018 I had used Ralink 7601 USB wifi 480Mbps costs 3.5 USD and its working fine. Now everything works good. No Trackpad showing for R5 but working smoothly. Now Bluetooth working Wifi usb Ralink 7601 working Trackpad Working HDA sound working Card Reader Working All USB ports working. If admin allow me I want to contribute a Post and all files for the High Sierra Installation for E6540 with my laptop configurations. That would be great if you would post your files! I have a few weird glitches I still can't figure out (I can't play video of any kind for some reason). Thanks!! Link to comment Share on other sites More sharing options...
sunilkumar Posted February 9, 2018 Author Share Posted February 9, 2018 Is your browser like safari, chrome or any other running ? If yes disable hardware acceleration from browsers. Link to comment Share on other sites More sharing options...
mattj88 Posted February 9, 2018 Share Posted February 9, 2018 Ok, I'll try that. I also can't play video in Quicktime or my video in the Photos app. Is there a system-wide hardware acceleration setting of some kind? Link to comment Share on other sites More sharing options...

jonny Posted February 16, 2018 Share Posted February 16, 2018 @Jake, I have followed the guidelines to get audio going in this thread and have not been able to do so. Audio is not listed in System Report->Audio. It's a Dell E6540 with HD8790M, A.22 BIOS. I see the audio and codec in Ioregistryexplorer (link). What am I missing here? http://www.mediafire.com/file/5bince4o88owaph/E6540_ioregistry.zip Link to comment Share on other sites More sharing options...
