Hello everyone! I'm a bit late to the party, as I've been learning more about OpenCore in preparation to update my laptop (Lenovo Ideapad S340-15IWL) to Big Sur. I'm ready to share my EFI for those who may be interested. From what I can tell, everything is working:
audio,
video + HDMI,
USB ports,
keyboard,
integrated camera,
volume control keys,
brightness slider + control keys,
Null ethernet for App store access,
sleep & wake, and
(importantly) trackpad!
Interestingly enough, my touchscreen also works as it's recognized by Big Sur.
For those with the RealTek SD Card reader, I've included the Sinetek kext (not enabled by default). Generate/use your own serial number, UUID, etc.
One caveat- dual booting to Windows 10 via OpenCore's picker does NOT work, and results in an ACPI_BIOS_ERROR. I'm sure this is due to one or more of the DSDT patches. For the moment with Windows10, press F12 when booting to get the UEFI boot menu; then boot windows from there.

Edit - use (overwrite the one included in ZIP file) the updated SSDT-XOSI.aml to resolve the ACPI error upon dual booting Windows.

Edit - I've tweaked the FrameBuffer patching. See attached pic. Maybe it'll help if you have any HDMI problems.
Thank you man. This made a real hard transition a breeze. Just copied your EFI and generated SMBIOS and NVRAM stuff and bam! Worked like a charm!

Edit: HDMI with sound works after sleep/wake confirmed.

Has anyone tried YogaSMC with this laptop? I'd love to try hackintosh on mine if this was possible. I already enjoy the benefits of YogaSMC.kext on my Thinkpad x240 and works great.

What's the difference and why should we use it?

hello thanks for share, but i can install macos bigsur
The installation stopped as shown in the picture, I think due to the bios config is wrong, I followed the bios guide https://github.com/WraithWinterly/Lenovo-Ideapad-S340-Hackintosh-Catalina-OpenCore.
