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
@curtistn hello, after updating to Big Sur 11.5, the brightness slider doesn't work anymore. Do you have maybe the same problem? Any solution? Thanks for your helpHello everyone!

@Patrick545 I haven't tried it lately.@curtistn hello, after updating to Big Sur 11.5, the brightness slider doesn't work anymore. Do you have maybe the same problem? Any solution? Thanks for your help
How did you do that? Normal update from software update?
No. I downloaded the full installer (via the "installinstallmacos.py" script), then ran it to perform the update. Note: OpenCore 0.7.4 is the minimum needed for Monterey.How did you do that? Normal update from software update?
Thanks.. Should I just replace my efi folder with this one? Changing ofc the things in con fig.plist file.Open Core 0.7.4 for the Lenovo S340 laptop. Fill in your own Serial Number, UUID, etc. in the config.plist file; or use OpenCore Configurator 2.52.000 to generate them. I think everything works ok (your mileage may vary). On occasion, though, I still get a blank screen upon boot for a minute or so, then the login screen appears. It very well could be my IPS panel, or the framebuffer patching isn't perfect.
Basically, yes.Thanks.. Should I just replace my efi folder with this one? Changing ofc the things in con fig.plist file.
And then update like you told me before?
