Lenovo ThinkPad T420 with UEFI Only

zhangqq · October 15, 2013

Without those tags it just hung when shutting down(I already added SLPE ).

TimeWalker75a · October 15, 2013

@timewalker75a - wow that was easy. fantastic. just curious how do you/we know 1312 is the right max?!

@zhangqq - interesting. does this make shutdown work (period) - meaning it did not work at all - or that is makes shutdown work better (ie not hang)?

1312 is the maximum PNLF (Apple's Display Panel) can handle. And this is the value it defaults to after sleep, as in.. the brightness cap increases after sleep from 0710 to 1312.

Re: reset address and values - this fix was originally discovered by fassl and was needed for older hardware where FACP table didn't contain this data, so restart was not functional. Bootloaders are now altering this table and increasing it's length for platforms where FACP doesn't include this data. If you dump your native ACPI tables from clover by pressing F4 in GUI and then open up your FACP table from /EFI/CLOVER/ACPI/origin you'll see that this data is already in there .. and it only affects restart, which is done through PS/2 controller, which is a part of Embedded controller... so shutdown was fixed by SLPE, not this... this doesn't even need to be there.

Hi guys-

This is not important of course, but aiming to a perfect laptop running OS X...

The wifi light is not on, even if the wifi is enabled. Any easy fix that could correct this?

Thanks,

AJ

tluck · October 15, 2013

TimeWalker - thanks that is great information.

well the FACP table shows this info - which according to the WIKI,Clover will read and use. in this case the PCI bus. agree with that for the T420 - the reset values do not need to specified in the config.plist

@AJ - will look at this later to see if i can figure out which LED lights that up. there is a DSDt function called SI that i used to reset the power and sleep LEDs. may be manual since OSX may not have this?

@okcakep (get blank monitor if you're using custom EDID in config.plist)

then make this change in red (delete or change)

InjectEDID to false is enought if your EDID is not the good one it would become the good one in newer system

@okcakep : you're welcome

@all could you please add your signature

feed back about T420_UEFI_Clover-b2236_10.8.5_10.9.0_16-Oct-2013

As usual great work brightness is equal as before sleep

I add tluck's pack url in my signature (a way say :thanks_speechbubble: )

@timewalker75a : thanks for your contribution too

@tluck : thanks for the great pack you provide each time

pokenguyen · October 16, 2013

I want to install OS X Mavericks on Thinkpad T420s, how can I patch my own dsdt based on your patched files?

I also want to use ultrabay to replace my dvd drive by a hdd, I saw some posts long ago said that the system can only boot to internal drive Clover without it, is it fixed yet?

TimeWalker75a · October 16, 2013

Use shell from within Clover (new revision preferably) and add bcfg boot entry pointing to your optibay (utrabay?) drive. The entry will then appear under F12 boot menu..

@pokenguyen - there is dsdt.aml and dsdt.dsl (source with change comments) for any T420 - ready for use in the zip bundle. otherwise i don't understand your question.

T420s model can't use the same dsdt, but I think it will be very similar. I want to know which patches you applied to your dsdt so I can patch it myself.

Sheep_Reaper · October 17, 2013

I don't have a 420 to confirm, but gendalo and I have different t430's and it turns out that the dsdt's are identical. Likely it is true of 420's as well.

@Tluck now im using 10.8.5 with your package. work !!!. i must be reconfigure Athereos WiFi to pci168c,2b

Sound work perfect...thanks...!!!

@Tetone your EDID work...but i still get glich sometime

Update...

Suddenly no sound in internal speaker,

Headphone ok

AWON (0x05)

Store (Zero, SLPE)

Sleep (0x10)

I guess store(zero,SLPE) should be store(one, SLPE). (I won't use the tags for shutdown now.)

I also add Store (One, SLPE) and Sleep (0x10) to arg0 = 0x01 0x03 0x04.

Then I add Store (Zero, SLPE) and Sleep (0x10) ad the beginning of _WAK and _INI.

The shutdown and sleep work fine till now.

That's right - you GUESS, while Intel STATES:

Every state passed as the argument to _PTS is a sleep state, be it suspend type (0x1 and 0x3), lid 0x4 or soft-off (0x5).

tluck · October 17, 2013

@pokenguyen - misunderstood your model is a T420S and not plain T420. here is a zip of the original dsdt and current dsdt.dsl (with comments) - you can diff them to see what was add/changed.

t420_dsdt.zip

@okcakep

1) the sound loss from laptop speaker is known to be result of changes in 10.8.5 v1.8 AppleACPIPlatform.kext. laptop will lose speaker after wake from sleep. if you rollback to 10.8.4 v1.7 AppleACPIPlatform.kext this will not happen.

2) EDID and glitches. is your native EDID different than the one Tetonne provided. is it v1.3? look for 0103 string vs 0104 string. i am injecting a different EDID (v1.3 seems work) than what was native/built-in to fix the glitches.

in reality i never figured out why one EDID worked and another didn't. here were 2 v1.3 EDIDs for LCD 1600x900 - one was native (from windows) - i suspect it is the diff in detail clocking timings info? works is 96 Mhz and the glitchy one is 110 Mhz

Thank you very much, I'm new to Thinkpad and waiting my caddy to arrive before installing. I will give it a look.

Btw, I think you should replace VboxHFS-64.efi by HFSPlus.efi for better OSX Install support. With the drivers, you can create install usb for 10.8 by restoring InstallESD.dmg, or use createmediainstall tool for 10.9. Very easy.

I just studied P8Z68-V PRO's dsdt and found something interesting.

                }

                Method (SWAK, 1, NotSerialized)
                {
                    Store (Zero, SLPE)
                    If (LNot (RTCS))

        {

            Store (One, \_SB.PCI0.LPCB.SLPE) <== ASUS put SLPE here, it is the same as our SLPE.
            If (LAnd (LGreater (Arg0, 0x03), LLess (Arg0, 0x06)))
            {
                Store (Arg0, \_SB.SMIC)
                Store (One, GP27)

    {
        ShiftLeft (Arg0, 0x04, DBG8)
        \_SB.PCI0.LPCB.SWAK (Arg0)
        Store (Zero, \_SB.PCI0.LPCB.PLED)
        Return (Package (0x02)
        {
            Zero,
            Zero
        })
    }
}

I found the follow combination worked.

1) SlpSmiAtWake => true

2) Add SLPE = 0 to _WAK and SLPE = 1 to _PTS(arg0 = 1,3,4,5)

TimeWalker75a · October 17, 2013

And yet Asus board have HAD this shutdown bug in UEFI boot until endless figured out that it has to write 0 and not 1 to SLP_SMI_EN register (which is SLPE) .. whats SLPX - nobody knows and it's not even documented in chipset specification, while PM30+4 bit register is.

SlpSmiAtWake was my request to slice, and it's actually broken and is poorly implemented, all it does is makes a change to your DSDT to unconditionally write 1 to SLPE when _WAK is called. On Tiano firmware this results in broken wake, when the laptop has been put to sleep by closing the lid.

tluck · October 17, 2013

@pokenguyen - great. glad to have another voice and platform on this thread

HFSPlus.efi (i have an HFSPlus-64.efi) ... but sure i can give that a try- what does that do better that Vbox?

i made my 10.8 and 10.9 installers using this approach - basically put "BaseSystem" on the USB. made it more like "regular OS" so was more intuitive to me. These are my notes on how i do it:

format USB GUID with 1 or 2 partitions

expand and show all files in downloaded installer app

find and open/mount InstallESD.dmg in Contents/SharedSupport

extract BaseSystem.dmg (will be hidden)

restore this image to USB using Disk Utility

remove /Volume/USB/System/Installation/Package (link file)

cp -rp Packages (from installer InstallESD.dmg) to /Volume/USB/System/Installation/

extract (pacifist) mach_kernel from Packages/BaseSystemBinaries.pkg and put in USB/

TIPS:

turn on Disk Utility debug mode - you can see hidden partitions

run:

defaults write com.apple.DiskUtility DUDebugMenuEnabled 1

if your usb is disk 2

$ diskutil list

mount your ESP manually:

sudo mkdir /Volumes/ESP_USB

sudo mount -t msdos /dev/disk2s1 /Volumes/ESP_USB

unzip bundle (say in Downloads)

cp -rp ~/Downloads/EFI /Volumes/ESP_USB

cd /Volumes/ESP_USB/EFI/CLOVER

mv OEM OEM.NU

@zhangqq - well interesting and this stuff may work on a different Mobo/embedded controller. but, for me i am not keen on testing as i don't want to brick my box! anyway, i am happy with the restart and shutdown function currently.

Using HFSPlus.efi can boot to special Install USB, which can create Recovery HD after installing. Creating Install USB is much easier than your method:

10.8: Restore InstallESD.dmg to flash drive

10.9: Run the following command:

sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction

re: speaker audio not resuming from sleep ... doesn't Conexant CX20590 use EAPD on output nids?

You can try using the kext I have put together to check if it would resume properly after sleep-wake cycle.

You could look in the codec dump for the node number where EAPD sits at. By default the kext has it set on 0x14 (20), you can try defining it in config.

tluck · October 17, 2013

if i roll back to AppleACPIPlatform.kext from 10.8.4 (v1.7) the speaker works fine after sleep.

not sure what node you are looking for in your kext.

i think the speaker output node is 0x1f (31)

headphone node is 0x19 (25)
