Your discrete graphics is still enabled. Disable that should help with sleep. For Brightness control don't forget to add SSDT-PNLFCFL.aml, I think Lorys89 posted a few messages back.

This thread is a replacement of @Baio77's recent thread which made insufficient credits to the author and grabbed screenshots or copied/pasted stuff from other people's without authorisation or credits. It's not the way things are done here... Great to read that development work continued based on the well-known work made by Alexandred on his VoodooI2C driver. Developer @juico forked the work of other developer @blankmac, both publishing a driver for the following Alps trackpads: T4 USB (as fitted to HP Elite X2 1012 G1 or G2 laptops) I2C T4 (as fitted to HP ZBook 15 G3) I2C U1 (as fitted to Dell Latitude 7x80 or 5x80 and some Precision) At time of writing (Oct 2021), the drivers remain at an early stage of development and experimental for some Alps devices. All details and released drivers are available at the devs respective GitHub repositories: https://github.com/blankmac/AlpsHID https://github.com/blankmac/AlpsHID/releases/tag/v1.0 https://github.com/juico/AlpsT4USB https://github.com/juico/AlpsT4USB/releases Hopefully both devs can unite and come up with a single unified driver... The drivers appear functional and capable of supporting multiple gestures as stated by @Lorys89 on his GitHub-based Latitude 7280 guide: https://github.com/Lorys89/DELL_LATITUDE_7280 Edit - 13 Oct 2021: Juico pinged me to inform me that his fork is now deprecated and all work is now undertaken under Blankmac's repo. All details and binaries available at the following URLs: https://github.com/blankmac/AlpsHID https://github.com/blankmac/AlpsHID/releases
