Thinkpads Forum

Especially with "work normally when I connect external monitor via VGA", -- that uses the same GPU.
The laptop hardware should be OK

Obviously you don't know that these GPUs have TWO outputs:
- digital output for use on the (internal) LCD
- analog output for use on the (external) VGA-port.
Digital is the one that usually fails first (as probably in this case).
Read up on these bad nVidia chips in 2007/2008 and the enormous class-actions from several major laptop manufacturers.

Actually I think the main problem is sloppy GPU throttling. I guess it depends on combination od DSDT and AppleGraphicsPowerManagement.kext. Laptop simply doesn't ramp up the clock of GPU quickly enough when something more complicated happens on the screen (like moving big window). I will have to try different AGPM kexts, perhaps there is the solution... Best, a.

With osx 10.9.4 does not work with the blue thinkpad.

I should try blue "thinkpad" button to see it works or not under 10.9.4. The logic is indeed in DSDT, press once - full speed, press again - toggle back to normal speed (increasing speed only with temperature)

For me with osx 10.9.4 blue "thinkpad" button doesn't work. You know if I can change the dsdt to make it go always to the full speed? my T9500 comes to 90 degrees ...

Good to know that, I did recall it now, People tried to resell those GPU-failed T61 or T61p on eBay which only works with external monitor, but not internal LCD. some people fix it by putting the motherboard into oven for heating 20 minutes (youtube)

There is defective internal soldering issue in nVidia chips around 2007/2008.

Well, choppy animations in OS X has nothing to do with the fact that GPU is working properly or not. It is because of AGPM.kext, you should edit that kext to match up with your GPU. There's another thread in this forum about installing Mountain Lion on the T61, you should find an edited AGPM kext for 140m. The problem - as in this state - does not affect the FX 570m, because on that, the GPU is running on constant full speed. That's why I want to create a proper AGPM for 570m. Please if someone could help me in that, write as soon as possible.

tl;dr:
I'm back and you can count me in.

long version:

Hello Madara-San,
I'm sorry not answer your suggestion from juni 4th - the graphics chip of my T61p died two days therefor. I'm not sure if it died by the NV-bug or if I killed it by stressing and overheating it. Unfortunately the often suggested reawaking method of baking the logic board didn't show any effect. Well, there was an PowerMac G4 standing next to my desk and a Haswell logic board with cpu on the desk - let's say I have an Quicksilver (2013) now

But I found a solution to get graphics powermanagement working before I was to eager about it and the graphics chip quitted it's duty. While messing around with the Haswell combo I manipulated too many kexts to remember what I did exactly to get grahics pm working. Today I recieved a second (cheap) T61p from ebay with crashed screen but working logic board, so I'll have a new testing machine in the next days.

Best regards,

Laberlohe

Update:
T61p is fix and my old install booted succesfully.

Graphics powermanagement is working:
First session of reverse engineering my own mess shows I just turned on Chameleon's GraphicsEnabler..?
org.chameleon.boot.plist: edit: When running on battery FX570M clocks down to 168/99. I'd say it's working

Perhaps I'm misunderstanding your post, but the GPU nicely changes speed and idles down on my T61p. The only issue is that after a sleep/wake it runs full speed all the time.
I'm not using modified AGPM kext.
Using Madara-san DSDT. Have latest FakeSMC (Kozlek) and SMBIOS tuned to MBP 5,1.
If you want, I can post my kexts.

I'm using patched AGPM from Madara-San's second kext pack alongside DSDT from this pack. SMBIOS is also MBP5,1 - but I have working graphics powermanagement even after sleep.

Dunno if it effects graphics pm but I'm still running the first iteration of Mavericks (10.9 without any .x update)...

I wouldn't mind fixing the after-sleep PM issue. I'll look for that AGPM kext. Thanks.
(it might be just cosmetic though, as my temps are still reasonable)

That is unusual that you use GraphicsEnabler in 10.9, there is native support for these GPU.

BTW, I don't think I have choppy animation that was mentioned. For example, Mission Control transitions are usually smooth.

Oh, so did it worked with my old kexts? That's strange, because for me the GPU Power Management never worked on the T61p. Laberlohe, please can you post your kexts? Do you use myhack, or something else?

Also the "Grafikkarte" temperature values are pretty high on your screenshot, but maybe that's not a big deal.

Hi, I use mandara-san guide with his kext and files, but the fan goes fast only when I press thinkpad blue button,can I always go the fan faster?

Well, I think the temperature isn't that big thing - ambient temp was 36° C and some benchmark ran before I took the screenshot... (I'm not so much interested in temp than in working time on battery)

"my" kexts? U kiddin'? Most work was done by others
myHack.kext
Extra folder

Maybe Chameleons GraphicsEnabler-option makes the difference? And myHack removed the AGPM.kext from S/L/E while running a "full fix". Installation was done with a modded myHack usb keydrive (stock/generic Extra folder swapped with yours on the keydrive itself)

I see... did you get "AGPM controller - unknown platform" message when you boot verbose mode?

Just rebooted (1st time after 2 weeks ), but I didn't see the line "AGPM controller - unknown platform". I noticed "Lenovo Quadro FX...." instead. Console doesn't say anything about an unknown AGPM controller.

Then it's near perfect. Do you have a dock? Unfortunately I don't, so I would like to know if DVI port works with that configuration you use.

The MiniDock DVI port doesn't work with your default DSDT, but with Sieglind's dsdtv2.aml - unfortunately only without powermanagement

That means power management does not work when DVI plugged in, or when you use his DSDT?

Erm... my fault - dsdtv2 is one of your files, sorry. It gives DVI out via Mini Dock, but while DVI is plugged in PM isn't working. In normal use (only internal LCD) PM works like a charm. Addionally temperatures are 2-5° lower than with your default DSDT (would there be a chance to combine the default DSDT with dsdtv2? Sleep and fan speed sensor from default DSDT and DVI out capability from dsdtv2 would be great)

Sorry but where that is set with the thinkpad blue button the fans go to the max?
Can I make it go always to the maximum? also with some sofwtare ...

Anyone have a dsdt with DVI out on mini-dock and power management?

Hello my fellow thinkhackers,

I'm just reporting that I was able to install OS X 10.9.1 with Madara-san's kext pack v2 and Sieglind's dviDSDT on my R61i and it's working *almost* fine.
Well, good job done here, guys - I'd like to thank you all

Unfortunately, I'm still having couple problems with my installation:

• CPU freq - my T8100 is idling @ 728MHz (instead of 800) and full load @ 1.9GHz (instead of 2.1) - I'd like to get my full performance back
• Sleep is unreliable - most of the time, it's slow, but works fine - screen gets dark and I have to wait like 20s before it goes to sleep - I can live with that.
  But once or twice a week, screen just gets dark and nothing happens - it can stay like this forever
  I have to power it off forcefully, by keeping the power button pressed... nothing else can help.
  R61i is my daily driver, so this makes me avoid the sleep feature at all...
  Could someone point me where to look for a fix for this problem?
• NVS 140M - with dynamic freq changing, it's laggy as hell - probably bumping the freq up is just too slow (AGPM kext failure?).
  After waking up from sleep, freq is locked @ max, which is actually a good thing, because it's no longer lagging.
  Is there a way I could lock my GPU @ max speed forever?

I'd really like to fix all of those 3 problems, so any advice will be appreciated

BTW. I'm using my R61i all the time connected to AC, so I don't really care about any power saving features or freq scaling - I'm more interested in getting full performance and fully working features, like sleep.

I did a test with Win7/64 and minidock: No Powermanagement with both Display´s! If i use only one Display, Powermangement is working. Maybe in Mavericks it´s just the same.

So, using these kexts I've gotten everything working except for Sleep. For whatever reason, sleep just makes my t61p make 2 beeps and then just..hangs. Fan's still running, etc, though the moon icon stays lit.
Any ideas?
Everything else is working beautifully though - even got bluetooth and wireless working with a wireless module from a 2008 Macbook.
Whoops, need more info here.

Hi pit1337,

Have you turned off Hibernation yet? It can make sleep take longer to start.

Here's how...

Open a Terminal window.

sudo pmset hibernatemode 0
sudo rm /var/vm/sleepimage

Reboot

Your other issues were discussed earlier in this post.
There is a procedure developed by jzhang18 to get full frequency speed out of the processor, however some have reported audio distortions in built-in audio and extrernal USB audio devices.
Myself, I was able to get full frequency processor speed by using Clover bootloader, but also experienced the same audio problems.
My GUESS is that IDA is confusing OS X into reporting a slow CPU and FSB speed, even though your BIOS is actually running the CPU and FSB at full speed (OS X does not support IDA). When you correct for that, you are unknowingly over-clocking the FSB... which causes clock errors in audio devices.

In other words... the slow FSB and CPU frequency is only a cosmetic issue in OS X.

However, some other members of this forum might disagree with that.

I have compared benchmarks of my Dell D630 with my Thinkpad T61 ... which both have the same processor and similar GPU. Interestingly, the T61 benchmarks as faster than the Dell (even though the Dell has correct FSB, and IDA can be disabled). I believe IDA makes the thinkpad faster than the dell, but confuses OS X into reporting a slow FSB. So, it's only a cosmetic issue. Again, I expect some to strongly disagree.

You can scroll back and read about it.

Peace.

Someone tried 10.9.5? Sleep problem still remains? If yes, we stuck @ 10.9.1

Sleep problem still remains with 10.9.5

Someone tried 10.10 beta?

has anyone tried to upgrade to Yosemite from the store?

Not yet, I'm on 10.9.1. Sleep is necessary for me If there's anyone without working sleep, I'd suggest to try it out!
