Mihari Oyama Posted May 9, 2021 Share Posted May 9, 2021 I have dell latitude e5540 which works for 95% but I have some issue about keyboard: - Fn+F3 (Scroll Lock) = Decrease Brightness, which mapped to FN+DOWNKEY. I want to disable this key. in Console.app it shows 46=6b - Fn+Insert = Increase brightness, which mapped to FN+UPKEY. I want to disable this key as Fn+F3 in Console.app it shows e045=71 - Fn+F5 (Toggle Trackpad), I haven't mapped this key, but when I pressed this key, it only shown: ApplePS2Keyboard: sending key e01e=80 down - Fn+Home & Fn+End = Trackpad Toggle, I want its mapped to Fn+F5, and FN+End=Capture Screen in console.app it shows: Fn+Home: ApplePS2Keyboard: sending key e037=0, 0=80 up/down Fn+End: same as Fn+Home Fn+Insert: ApplePS2Keyboard: sending key e045=71 up/down And my keyboard always generate ApplePS2Keyboard in Console.app although I disabled via ioio My EFI: https://github.com/quynkk5/E5540-Hackintosh (In release tab) Link to comment Share on other sites More sharing options...
Administrators Hervé Posted May 9, 2021 Administrators Share Posted May 9, 2021 Afaik, you cannot disable those Fn-<key> that act as others would be expected to, even if you apply patches to get the expected keys to work. Link to comment Share on other sites More sharing options...
Mihari Oyama Posted May 10, 2021 Author Share Posted May 10, 2021 hmm... How can I patch these key via SSDT or DSDT? I read a post about this and they said: "0x01xx: standard PS2 codes... make/break separate 0x02xx: extended PS2 codes (e0)... make/break separate 0x03xx: standard PS2 codes... make/break combined (eg. make and break are sent with only a single notify) 0x04xx: extended PS2 codes (e0)... make/break combined" Link to comment Share on other sites More sharing options...
