black.dragon74 Posted December 8, 2017 Share Posted December 8, 2017 Used sleepwatcher to create a bluetooth reset after wake and that solved the BT connect after wake issue. All i need to solve now is the trackpad non-wake issue and i should be good. Add a few lines to unload the trackpad kext and then reload it. You can see how it is implemented in my guide for ELAN1200. See https://osxlatitude.com/index.php?/topic/10165-guide-elan1200-i2c-trackpad/ Regards 1 Link to comment Share on other sites More sharing options...

tldrbro Posted December 9, 2017 Share Posted December 9, 2017 I also updated to BIOS 1.6.5 and it effectively seems more responsive ( in Windows). @Jake_Lo When you get the time, could you also take a look at my origin folder since I have HD520? Thanks in advance. origin_BIOS1.6.5_HD520.zip Link to comment Share on other sites More sharing options...
