If I do that, the dell will warn me about not having a disk installed and won't boot to the installer at all. Link to comment Share on other sites More sharing options...
ONRA Posted May 19, 2021 Share Posted May 19, 2021 @Jake Lo I added SSDT-TPDX. Trackpad is working now but it's a bit strange. There is just the pointer who's moving but I can't select or open anything. I have to press the left button to select or open something. I added SSDT-BRT6 & SSDT SSDT-OCWork-dell from your EFI/ACPI folder too. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted May 19, 2021 Administrators Share Posted May 19, 2021 Tap to click isn't usually enabled by default. It can be enabled in the TrackPad PrefPane, if such PrefPane is offered to you of course. Many systems with I2C TrackPads do not get the TrackPad properly recognised as such.

ONRA Posted May 19, 2021 Share Posted May 19, 2021 @Hervé Yes I got the Tackpad PrefPan . I enabled, disable and re-enabled Tap to click just in case but it's not working properly. There are another SSDTs from @Jake Lo folder I didn't installed yet: -SSDT-GPRW.aml -SSDT-USB-Reset.aml Do you think I need to install it ? I'm gonna try just in case. I will learn from my own mistakes I also see that I have SSDT-XOSI.aml in my ACPI folder and it is not in Jake’s folder. I will try to uninstall it to see if it has any impact.

Administrators Hervé Posted May 19, 2021 Administrators Share Posted May 19, 2021 SSDT-XOSI is unrelated; keep it. That table's purpose is to set OSYS to the highest possible Windows version equivalent and ensure things such as USB3 is enabled on older systems or that brightness keys will work.

Moderators Jake Lo Posted May 19, 2021 Moderators Share Posted May 19, 2021 @ONRA You haven't confirm what touchpad you have, is it indeed an I2C Alps? Most new Dell Latitude I worked on has I2C Alps but never heard such strange behavior. Perhaps it's a new variant of the I2C Alps and it's not quite supported yet. You can try contacting the developer for help. @KeinOhrHasen I guess you'll have to swap out with a spare SSD to test. Others in this thread didn't have such issue but I don't know what disk model they have. They will have to chime in. Link to comment Share on other sites More sharing options...
KeinOhrHasen Posted May 19, 2021 Author Share Posted May 19, 2021 I inserted two disks by now - disabled the disks in bios setting - but the installer keeps failing. Archiv.zip attached are the 3 error logs I had Link to comment Share on other sites More sharing options...
ONRA Posted May 20, 2021 Share Posted May 20, 2021 @Jake Lo I haven't found out what type of trackpad is on my Latitude 5510! I read on some forums that it could be a Synaptics. Is it possible? Link to comment Share on other sites More sharing options...
