Hi @bhedge, would you let me test your EFI to see if it works with my z50-70? I would be very grateful. Of course it clears SMBIOS. Excuse my english
Hi folks,
I've been having a fiddle about with my Z50-70 and finally managed to solve the lid/sleep conundrum. It's basically the same approach that always used to work - removing _PRW from the LID0 device. I don't really understand why recent attempts haven't worked but if you put the following in your ACPI patches section it should fix it. I'd rather it was an SSDT as it's a bit more elegant but I couldn't get it to work.
It works for me on Monterey with Opencore 0.8.3.
Hope it works for you!
