KarlosMarx, just to confirm, I assume you're using a 330S?  I've just checked the following and it seems to work okay for me.  https://imgur.com/a/I3bR6UN . I think the warnings can be safely ignored.

Yeah it's a 330S 15ARR. One thing I just noticed from your screenshot is that the code in your DSDT seems to be on different lines than mine? For example your _PSR is on 5247 and mine is on 4838. Is it possible we have different BIOS versions?

I'm on the latest bios version but I think the difference in line numbers is because the application maciASL that I use adds in blank lines.  e.g. https://imgur.com/a/DQkio7D

 

 

Does it compile with no errors if you remove line 4868? (The one which starts AFN4 (Local.... )

just tried that and I'm not getting any errors. Still not sure if I should load it now because I have no idea what that line was for.

I'd recomend going back through the thread and looking at what MisterFlibble has said and the steps they typed up. A lot of what we're talking about here also comes from this reddit thread:

https://www.reddit.com/r/Amd/comments/a2vs55/i_successfully_disabled_stapm_and_increased_the/?sort=confidence

 

I'm pretty decent with computers but a lot of this stuff is a little over my head and I haven't been able to get it working yet. I'd recomend chilling out and waiting for someone to type up a comprehensive guide to all this.

 

Also I had a bit of trouble finding a .aml compiler that worked on windows (most of them are for MacOS) so I've attached the one I ended up using which seems to work alright.

This is literally the most ridiculous issue for a laptop i've every seen, and I sadly just purchased a 330 15arr with 2700u. If a few people on reddit and this forum can figure out that the problem is STAPM-related and because whoever at lenovo typed 15 instead of 20 or 25, its ludicrous to think that the same people who developed it haven't heard out it or figured it out easily. Even more worrying is that this doesnt even require to much effort to fix once you know where it is, and is probably because the reps here aren't bothering to push it up the chain.

As soon as I get my laptop im installing clover bootloader and patching the DSDT as boot, or if its easier finding a compatible BIOS with correct STAPM limits since lenovo loves gimping laptops and selling them as lesser models. I know OEMs don't care about a problems a product has after launch but come on, this is one that could rake in more money, seems like an obvious incentive relative to the non existent effort since your consumers have done it for you already.

 

15 ------>  >=20. Please and thank you

I was just wondering, if someone has a DSDT file that's been modified couldn't they just upload it for other people to load in Clover? If we're all running the same hardware and bios version there wouldn't be an issue right?
