You could have at least given proper credits or modified the guide so you don't mock the original author. I own the original guide (I have proof on my personal blog). You even copied my github work and no credits given or guide modified. Can a mod please intervene ?

Thanks! Fixed my BT issue in Sierra. I also have a CSR BT Dongle Product ID: 0x0001 Vendor ID: 0x0a12

Ok. That makes sense now. But the brightness slider is working fine with the patched ACPI and Intel Backlight kext. However, the wake from sleep is still not working. I guess so. It was just for testing purposes. Signature updated.

Ok, That was a mistake. I have made an Unibeast drive just to check the right VRAM. I have read somewhere on internet that Chimera/Chameleon bootloaders can provide the correct DVMT-preallocated. Chimera reports 31MB video memory. So maybe the DVMT-preallocated is 32MB. I'm not sure anymore...

Anyway, it looks like the DVMT-preallocted memory is really 128MB. After reading this post https://www.tonymacx86.com/threads/guide-intel-hd-graphics-5500-on-os-x-yosemite-10-10-3.162062/ ; it's quite safe to say that the DVMT-preallocated is 128 MB. I'm not sure if that changes anything at all...

Yeah, I heard about that. It's unfortunate that I can't find these hardwares where I currently am.

Well, I'm not quite sure about that. This is what 2.25 BIOS update README file contains: - If the UEFI BIOS has been updated to version 2.24 or higher, it is no longer able to roll back to the version before 2.24 for security improvement. I can't find the previous BIOS on Lenovo website either ...

No problem. I usually download the kexts from RehabMan's bitbucket. The strange thing is that I even tried a config.plist from someone having a T540p (with a slightly different hardware though); the laptop ig-platform ID still didn't work. I am almost sure that it has something to do with the...

I'm not sure if I really know what's the difference. But thanks for clarifying it.

I recorded it. I'm uploading the entire video on youtube. But here is the screenshot first.

This option appeared after I installed the latest bios update. It's not a modded bios, even though I'd really liked that because I want a compatible network card. And how am I exactly supposed to take a screenshot if the laptop directly reboot itself? Thanks anyway for your all help. I will...

Sorry about that, I have edited it.

This is what I'm talking about.

I have already specified that. But since Sniki asked me to test, I had to test it. Only 256MB and 512MB options are available in my Pre-allocated DVMT. Is there a guide to make a patch for these two DVMTs ? Thanks.

I have attached an archive containing these files. - The 0A260006 ig-platform ID didn't work neither with 9MB patch nor 128MB. Results are the same. Laptop reboots after DSMOS has arrived. - Sound still broken - Wake from sleep still not working - Reboot & shutdown not working - Battery keeps...

See attachments below. Sorry. I accidentally added a stup!d ";". The correct link is https://www.tonymacx86.com/threads/guide-lenovo-t440s-clover-uefi.158369 I was thinking the same about the ig-platform ID and the the DVMT. Just need confirmation and eventually a fix. That said, do you know...

No, it only has Intel. Clover GUI also detects one video card: Intel HD 4600 Yes, Lenovo X220 patch from RehabMan's repo My apologies. I was mistaken. It seems to be ALC292. Device ID is 10EC0292 Yes, after applying a manual patch from this thread...

Hi, Thanks for the great support! First, I have to admit that RehabMan indeed does a great job here on this forum. He surely spent time trying to make noob friendly guides. But not everyone on the forum understands programming. So when it comes to things like DSDT/SSDT patching, most of us...

I just tried, the wake from sleep isn't still working. I also forgot to mention since the beginning that the battery drain even faster when I put the computer to sleep. I mean REALLY FAST! Like -1% each 30 seconds. Right, I have attached the Clover folder with these changes. The ACPI files in...

RehabMan had asked me to provide similar files which I did on my thread related to the problem. You can get it from here https://www.tonymacx86.com/threads/lenovo-t540p-sleep-and-mas-problems.217561/#post-1463073 I have attached some pictures of my BIOS. Had to compress them because they were...
