Liem Vo Posted May 16, 2018 Share Posted May 16, 2018 Hello, I've successfully install High Sierra on E7480 i7600U. But the touchpad does not working, i've tried VoodooPS2, Redefined ALPS kext, VoodooI2C but none working. Also i have problem with Apple backlight, i can only adjust brightness after sleep/wake (It immediately wakes after sleep a few seconds) Audio ALC256 not alway works, sometime not working after restart. Thanks in advance debug_19438.zip Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted May 16, 2018 Moderators Share Posted May 16, 2018 Try this DSDT, should get you touchpad on boot, but disabled after wake. For audio, disable the AppleHDA patches in the Config file under KextToPatch since you're using AppleALC.kext DSDT.aml.zip Link to comment Share on other sites More sharing options...
Liem Vo Posted May 17, 2018 Author Share Posted May 17, 2018 Thanks you, but touchpad still not work after using your DSDT. The sound did not work the first and second time restart after i disabled AppleHDA patches. It worked after the third restart. debug_5136.zip Link to comment Share on other sites More sharing options...
Liem Vo Posted May 17, 2018 Author Share Posted May 17, 2018 I'm able to make the touchpad work by copy the VoodooI2C kexts to /L/E, remove AppleI2C kexts and use GPIO pin 0x0000. But It now just like a mouse, how to make the 2-3 fingers gestures works? Also i have problem with sleep, it wake immediately after sleep a few seconds. debug_2482.zip Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted May 17, 2018 Moderators Share Posted May 17, 2018 Hmm, according to your DSDT, you're using GPI0 pin 0x0055 Try this DSDT for sleep DSDT.aml.zip Link to comment Share on other sites More sharing options...
Liem Vo Posted May 18, 2018 Author Share Posted May 18, 2018 Sleep working now, thanks you! Could you please tell me which patch you applied to DSDT? debug_15144.zip Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted May 18, 2018 Moderators Share Posted May 18, 2018 This one by Rehabman to fix sleep Can you confirm touchpad works on boot and after wake from sleep? Also can you test if adding the (2) I2C Controller patch by Coolstar to Config kextToPatch, you can install VoodooI2C.kext to /L/E without having to remove AppleI2C kexts from /S/L/E Link to comment Share on other sites More sharing options...
Liem Vo Posted May 18, 2018 Author Share Posted May 18, 2018 My touchpad work on boot and after wake, the GPI0 is 0x0000 I've tried I2C Controller patch by Coolstar but not work for me. On boot it stuck at: AppleIntelLpssI2CCController::_servingMatchingTimeSubr: fTimeServiceMatching timed out, fNotifications 0 I removed Apple I2C kexts then work fine. Almost everything worked on E7480, except some minor issues: - Weird sound lost, if it lost i have to restart 2 times and it works again - Brightness adjust only work after sleep / wake - Touchpad multi touch gestures, VoodooI2CSynaptics not support yet - If HDMI plug in and close the lid, instead of sleep all window transfer to HDMI monitor and laptop screen completed out, no way to turn in on again. - Some time boot stuck at busy timeout[0] Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted May 18, 2018 Moderators Share Posted May 18, 2018 Update Lilu.kext and AppleALC.kext. It's been updated with EAPD Fix for audio after wake. With external monitor connected, it's normal for system not to sleep with lid close, you have to select sleep from Apple Menu. As for the screen staying blank, you might have to try injected EDID Link to comment Share on other sites More sharing options...
Liem Vo Posted May 21, 2018 Author Share Posted May 21, 2018 Updated Lilu & AppleLC kexts seem to fix the issue. I will try injected EDID. Thank you Jake Lo. Link to comment Share on other sites More sharing options...
