Dell Latitude E7470 - HS issues

[Guy Ro]

Thanks Jake. I went for the 1560.

Btw, is there a quick fix for the caps lock issue (need to double click) ?

[Guy Ro]

Also for the brightness control of the screen? Is it possible to make it functional?

I see in clover configurator that setintelbacklight + setintelmaxbacklight both not selected. 

I tried to select them, however - it showed only black screen after reboot. so I recovered it and deselect it and not it boots normally again with apple logo etc.

Replace the contents into /EFI/Clover

Copy the kexts in /EFI/Clover/kexts/Other/CopyToLE to /Library/Extensions

Repair permissions and rebuild cache

No fix for the CapLock issue with the current ApplePS2Controller.

I am still unable to change the brightness.

 

I replaced the files and copied to extensions. I also ran the permissions.sh

I see also many other kexts in the extensions folder that I copied there previously from the generic installation guide. could it be a problem?

 

When I run permissions.sh or sudo kextcache -i / I see the following errors:

do you see the brightness slider in Displays preferences?

 

[Guy Ro]

I do - changing it manually in the settings works now.

However, the keyboard hotkey doesn't work (can it be mapped to fn?). Also, I am now suffering that the machine gets stuck sometimes (freeze for 5-7 seconds) since the changes in the EFI. Any idea why?

 

My display card is Intel HD 520 1536 MB graphics.

[Guy Ro]

To make it clear. the audio hotkeys (fn) works (f2+f3), but not brightness (for some reason mapped to fn+f6, only decreasing brightness is mapped). Also the Trackstick Scrolling function doesn't work.

 

I tried to implement it via Karabiner:

No option for point devices / cursor move (seems like the trackpad is not detected although it works).

also it is unclear how to add the xml file.

 

UPDATE:

I just found out that the key maps are wrong. also, Karbiner was updated and the new version doesn't support xml anymore but only json. does anyone has this json file? or old version of karbiner? other solution to force the correct mapping for e7470?

 

I tried this converter but it doesn't work https://github.com/durka/karaconv/

 

 

[Guy Ro]

I configured Karabiner manually - here is the json file for the new version.

need to place it in ~/.config/karabiner/

 

however, It doesn't include the trackstick scrolling (I couldn't solve it)

[Jake Lo]

Use Karabiner-Element instead.

See here for more info

Use Smartscroll.app for track stick scrolling.

I received the dw1560, however seems like it is not recognised on the laptop. in the bios it says wifi module/bt: none.

Any idea if this module is even supported on latitude e7470? I have the recent bios version.
