[Guide] Lenovo ThinkPad T440P

[Sniki]

Hello Sniki! Thanks for your work.
Unfortunately, there is still error.
It can't boot with graphics glitches. Both v1 and v2 meet same problem.
Problem reporting files and boot verbose video(not clear) are attached.
(If you can't boot, a bare minimum is:
- Boot verbose, attach photo
- Attach EFI/Clover folder as ZIP (press F2 then F4 at main Clover screen before collecting). Please eliminate 'themes' directory. Provide only EFI/Clover, not the entire EFI folder.)
Note: I disabled EH1&EH2 in BIOS so I remove the .AML.

@RehabMan maybe can give us a clue about the glitches.

Possibly failure to enable legacy boot/CSM in BIOS?

Possibly failure to enable legacy boot/CSM in BIOS?

I will test in tomorrow morning

@Sniki @RehabMan
There are the test results:

• UEFI only+CSM off+SSDT v1
  
• UEFI/legacy Both+CSM on+SSDT v1
  
• UEFI/legacy Both+CSM on+3 patches from AddProperties and InjectNvidia=Yes - Boot successful
  
• UEFI only+CSM off+3 patches from AddProperties and InjectNvidia=Yes - Boot with graphics glitches

BTW, how can I know if the graphics card is disable or not?

It sounds like your ACPI configuration is not properly disabling the Nvidia graphics card (proof: you need to inject the spoof properties via AddProperties, Inject/NVidia=true).

Do you mean that I should use AddProperties, Inject/NVidia=true and DSDT at the same time?

No. It means you need a working SSDT that properly disables your Nvidia card. Because the current one clearly isn’t doing the job.

Provide new ACPI dump (press F4 at Clover menu), post EFI/Clover/ACPI/origin. I’ll take a look at your ACPI code and see if I can find out why calling _OFF isn’t disabling the card.

Thank you very much! ACPI dump is attached.

Try this SSDT.

Try this SSDT.

Still show this... lose my mind...
