@havrancek
I also had trouble installing the 06 releasease. I did the following:

Uninstalled NHC
Reboot
Installed NHC
and it worked :-)

@Lomax
Could you pleas epost or send me your ibm.xml AND a screenshot of NHC --> Info tab --> Show computer hardware details and then the first page (With System) ?


Regards


Carl

Lomax

i assume you're after a ACPI file for an X31? heres the ACPI i use for mine, you might have to edit the model number unless you have the same as me:
IBM.XML
Code:
<?xml version="1.0"?>
<IBM>
  <Model name="2672PG9" location="MAINBOARD" class="TPFancontrol" file="IBM.cs" />
</IBM>

..as far as i can see the .CS file seems to be pretty standard.

Lomax,

Have you applied the "Core2Duo patch"? You need to, even if you don't have a Core2Duo processor. Other than that, below is what I did for setup . . .

1. Install .NET framework
2. Install NHC
3. Install Core2Duo patch (follow instructions in README)
4. change IBM ACPI/ibm.xml file to reflect model number (e.g., 23733UU)
Code:
<?xml version="1.0" ?>
- <IBM>
  <Model name="23733UU" location="SYSTEM" class="t43p" file="IBM.cs" />
  </IBM>

5. copy ibm.cs and ibm.xml to nhc/acpi folder

Hope that helps

Hi there,

since Version pre 06 you don't need the patch anymore...

Live and learn . . . :roll: I guess it might be time to upgrade to "pre 06". Is that why my "location" and "class" values are different from skanky's?

anyone else noticed that using pre06 in vista, the cpu stays at max all the time when using dymanically switching profile? more importantly, does any have a fix for it that doesnt involve manually changing profiles?

it makes my machine idle at 2ghz, which pushes the temps up which makes the ACPI fan controlling and undervolting rather useless.

ore06 switches fine in XP, wonder why vista is a problem..

edit: installing RMClock seems to make the cpu automatically adjust when needed.

Thanks for your reply Carl, sorry but I don't have imaging software currently on this machine so can't get you screenshots right now. I have found something interesting though, my problem seems to have something to do with Windows 2000. I also have an X32 which was running XP and NHC + ACPI was working fine on it. After I "upgraded" it to Win2k I now get the same "ACPI Control System has not been configurated" error as I get on the X31. Same config, same xml file. Isn't NHC compatible with Windows 2000 (with .Net 2.0 installed)? :shock:

Cheers,

Lomax

:!: My problems are even worse than that it seems! The fan has now completely stopped working and it doesn't come back on even if I uninstall NHC. I tried (stupid and dangerous) to get ACPI working in NHC by copying the DLL file that was built by NHC under XP (when it was working on the X32) along with the ibm.xml and ibm.cs files. No complaint from NHC but still no ACPI functionality and the machine gets _really_ hot now without the fan coming on at all! Have I caused permanent damage? :cry:

Hmmm . . . strange. I'm getting ready to revert to 2.04. I installed .06 a few days ago and with exactly the same settings (voltage, acpi, etc.) my machine is consistently running hotter by about 6 degrees C. Used to be 39C; now 45C. What's changed?!

Anyone have a config file for a T41p (see sig for specs)?

Also I am a newb when it come to NHC (can't get the Lenovo powermgr software to work for some reason), how do I apply the t41p config file?

Thanks in advance.

I am quite sure that you can use the T43p ACPI file for T41p's as well (I am using it with no problems in my T42p); get it here or here (the latter seems to be the newest, but I am using the former, without problems). After downloading it, check the "readme.txt" file, or see this page: Enable fine-grained fan control with NHC on Thinkpads - and follow steps 1, 2, 3 described at the top of that page - and you'll be up and running! :-)

Your next step is to find the lowest CPU voltages, giving you stable performance; this issue is discussed above (in the current thread). After that, also downclock the GPU - and finally then say goodbye to fan noise, and hello to longer battery times! :-)

Best regards,

Johan

I am having the same problem with NHC (Pre-Release 2.06, Personal Edition) as earlier described in this thread: In NHC (in the "Graphics tab") the following three boxes are all greyed out:

Enable ATI Powerplay Control in NHC
Activate Powerplay
Show ATI clock in the Taskbat Icon ToolTip

... completely regardless of how I configure the settings in Windows XP Start --> Control Panel --> Display --> Settings --> Advanced --> Powerplay (tab) and "Activate Powerplay" or not. The above all applies to when I run directly off mains; I haven't tried how NHC behaves if I run off battery.

In the same NHC Graphic Card Control section, I am allowed to enable (and alter) both ATI Clock Control #1 and #2 (although I have not yet understod when #1 resp. #2 are used?).

I am using a T42p, 2373-Q1U w/128 MB ATI Mobility FireGL T2. I have installed the T43p ACPI file referenced to above (and modified it for my T42p), and fan-control in NHC functions fine. I use NHC as being auto-started in Windows (hence I am not running NHC as a service). In the the NHC manual (Graphic Card Control section) I find no explanation why the above boxes are all disabled? What I simply want is this look! :-)

According to "Properties for ATI Mobility Fire GL T2" the driver version used here is 6.14.10.6547, dated 16-11-2006. I don't have the Mobility Modder.

What I want to do is let NHC control Powerplay, in particular when I run off mains... simply to reduce GPU heat dissipation as much as possible. I mainly use the T42p to browse the internet, e-mail and type... so very little GPU power is necessary. All help would be greatly appreciated! :-)

Thanks in advance, and best regards,

Johan

PS
: I am not sure if this problem might be related to the T43p ACPI-file; this link seems to indicate so? Also, This, this and this link may also shed some light on the problem - for those who can read German...! (which I cannot - sufficiently).

UPDATE: I just discovered this thread pointing to this thread which finally points to this thread where in particular the post by troubadix of Fri Oct 28, 2005 may perhaps shed some light on this issue...? How/if all this relate to NHC ver. 2.06 is however a little unclear (to me!).

Great post, Johan--detailed and clear! I experienced exactly what you described. It was only when I downloaded and installed this http://staff-www.uni-marburg.de/~schmitzr/ATIPOWPL.zip from troubadix's signature that PowerPlay was enabled in NHC. I'd say identify your current driver (i.e., the one thats 'working' for you right now!), make sure you have a copy of it (in case you want to 'roll back' to it), and go ahead and apply troubadix's driver. If it doesn't do what you want, you can always roll back to what you've got now. I can only say that it has been working (and working well) for me. Good luck!

Thanks a whole lot, Paul, for the kind words and the positive criticism; much appreciated - keep 'em coming! :-)

Well, sometimes I find threads quite hard to follow, if being too brief or assuming some not-provided knowledge from the (no doubt: Many!) non-specialist forum readers. If being more detailed (which is typically ”my way”!), this may have the negative effect that the post increase in size, but the advantage is that I am certain that more people may benefit from it. I have the clear impression that you share this approach… :-)

Thank you also very much for the information about troubadix’ ATIPOWERPLAY-driver. The reason for asking here, even after having found that driver mentioned yesterday in the Oct. 2005-post, is that NHC ver. 2.0 came out about a year ago, while troubadix’ driver is almost two years old – so I figured that the old driver had been kind of been ”superseded” by, or at least incorporated into, the new NHC… but now I know that this is not the case, thanks to you. I will for sure follow your (very valuable!) advice and backup the current driver, before playing with the new ones by troubadix. Is it sufficient to just copy to a safe place all the C:\Windows\system32\ati*.* and C:\Windows\system32\DRIVERS\ati*.* files plus the C:\Windows\system32\Oemdspif.inf or are there other files also necessary to backup?

I read the other day about your T42 won't shut down; nhc? ati? power manager?-problem, and I wish I could help, but (fortunately!) I have not experienced anything like that. After having installed NHC ver. 2.06, I have undervolted the CPU (only the two multipliers x6 @ 0.732 V and x21 @ 1.116 V), but I have not yet performed other than relatively short stability-tests (using the NHC built-in ones). Anyway, the T42p w/NHC v. 2.06 has been stable – except from one single instance, which I however don’t know if I can blame NHC: One day, when I shut down, the computer in stead rebooted (and I am absolutely sure that I did not select reboot)… some kind of glitch, but only seen a single time under one month of use.

Now; absolutely off topic! I have often read your posts, and have been constantly, pleasantly educated :-) while at the same time staring very envious at your location… the (in my mind!) extremely exotic, sonny Solomon Islands! ”What am I doing here in Copenhagen”, I’m thinking; ”I should be having an exciting job out in the Paul’s Pacific!!” What am I going to do to realize the dream of sunny beaches, white sand, the wind in the palms etc… you wouldn’t happen to be in need for an assistant for whatever simple, manual work? [I am an electronics engineer w/Ph.D. in antennas and microwaves, but I guess that such are relatively useless out at the Solomon’s?]. OK, Paul – I have to get to bed here – I am going to dream about the white sand, the coral sea, the dolphins, the coconuts, the Solomons… oooh, man, how I envy you!!

Thanks, again, Paul – and please feel free to send me a thought next time when you sit on your sunny beach :beer: - right there under the palms… (hopefully!) just enjoying the Pacific life! :-)

Best regards,

Johan

Hi everyone

After realising that I was entering the wrong model number (label on my machine states 2658J3M but NHC says 2648J3M, which do I trust?), I fixed an initial issue and at least got ACPI control working.

However it hasn't turned out to be of much use as I keep getting the following errors continuously while it is running:

ACPI.FIELD.ReadByOffset("_SB.PCI0.LPC.EC.ECOR", ref 0, 132, 16, "ByteAcc", "NoLock", "Preserve") . . . OK
ACPI.FIELD.Read("_SB.PCI0.LPC.EC.HFSP", ref 0) . . . ERROR
IBM.TPFancontrol.FAN.refresh( ) . . . ERROR
ACPI.FIELD.Read("_SB.PCI0.LPC.EC.TMP0", ref 0) . . . ERROR
IBM.TPFancontrol.SENSORS.refresh( ) . . . ERROR
ACPI.FIELD.Read("_SB.PCI0.LPC.EC.KBLT", ref 2) . . . ERROR
IBM.TPFancontrol.HARDWARE.refresh( ) . . . ERROR

Can someone please help me with this issue? I would really appreciate it as I have an issue with the fan on this machine where it kicks into full speed and refuses to slow down at random times. The Thinkpad is an R32, P4M 1.8GHz.

First, I don't anything about R32's, sorry, and I also don't recall having seen any reports of NHC w/ACPI running on R32's under Windows (as I guess you run Windows XP, although you are very little specific in your post?). If you want (better!) help here, I suggest you provide a few more details, such as informing about what OS you use (Win XP Pro, or some earlier version of Windows?), and exactly which ACPI-file you have downloaded (and from where?), and now try to get running?

While looking at the page Notebook Hardware Control ACPI Upload System, under the IBM section, there are quite a few ACPI-files (for a number of different ThinkPad's), incl. a couple of R51's - which one did you download?? If I were you, I'd first start playing with one of the R51-files, and not any of the T- or X-ThinkPad ACPI files.

One hint, which may or may not be of use, is this: Check the Power Management driver you are using now, and consider updating with ThinkPad Power Management driver for Windows Vista, XP, 2000, Me, 98 SE (this driver dated 2007/07/10, and for which it is mentioned: "This package provides ACPI power management support"). Again: I don't know if it will change anything, but it may perhaps be worth a try? Remember to make a (Windows) System Restore point before playing with new drivers.

PS1: I assume you have already read what it says at Notebook Hardware Control IMPORTANT section:
Code:
IMPORTANT!

Note you must have Microsoft's .NET Framework Version 2.0 or newer installed.
 
Notebook Hardware Control requires Windows 2000, XP or Windows Vista 32Bit.

PS2: More details of this users' problems is described in the "associated" thread: R32 fan control.

BR,

Johan

I'm fairly new to the world of NHC and have found this thread quite helpful. One question: is there any way to undervolt the GPU to reduce temperatures? I get stress test temps approaching 100*C, which I do not like.

To undervolt the GPU (assuming that you have a ThinkPad with an ATI GPU): I believe that you have this option if using the ATITool – have a look for yourself! However, beware of potential conflicts if simultaneously running Notebook Hardware Control and ATITool.

If you want to undervolt your GPU, I suggest you have a look at the thread Getting even lower voltages? – this seems to indicate that you should not go too low, as this might permanently damage the GPU.

I would be interested to hear of your experience with this investigation – thanks in advance for sharing.

Best regards,

Johan

^ Thanks, Johan. I've played with ATITools before and about all it did was make my system unstable. I just tried playing with it again to the same effect. I also didn't see a clean way of adjusting the voltages (as with NHC) without having to play with the BIOS.

I'm hoping that this is a capability that might be included in the next release of NHC.

In the meantime, I'm going to replace the thermal compound between my fan and the CPU and GPU. I used some inexpensive silicone-based stuff when doing and upgrade and perhaps a more careful application of Arctic Silver 5 will do the trick (but this is becoming somewhat off-topic).

I am having the same problem with NHC (Pre-Release 2.06, Personal Edition) as earlier described in this thread: In NHC (in the "Graphics tab") the following three boxes are all greyed out:

Enable ATI Powerplay Control in NHC
Activate Powerplay
Show ATI clock in the Taskbat Icon ToolTip


i had the same issue, only reinstalled the ati drivers (even when having the same version and rebooted. now it's not "greyed out" - however there are some sliders which i in fact don't know what are doing =))

As my X31 is fixed with a different Mobo and i don't have the floppy disk to change uuid and model name, I first identified the thing manufacturer as IBM (in NHC>Info>Show computer details) and since i have no model name (these are added by the tech's floppy) i deleted all the *.xml and *.cs installed this (mirror of what version i used) and edited ibm.xml this way

IBM.xml
Code:
<?xml version="1.0"?>
<IBM>
  <Model name="" location="PRODUCT" class="TPFancontrol" file="IBM.cs" />
</IBM>

I have been doing some follow-up for my GPU heating problems. Unfortunatley, Johan, I was unsuccessful in undervolting the GPU with ATITool (your post of December 18th). It seems that at present the only way to do so is by editing the video card BIOS (risky) or modifying the hardware to lower the supply voltage to the GPU (riskier).

I've instead reexamined my NHC settings to see if my fan was operating well. I'm utilizing the ACPI script configured as in your post of July 30 and have kept default settings (only editing IBM.xml and lenovo.xml to contain my machine type, 2379-DXU). I have noticed, however, that regardless of the (nonzero) "Actual Fan Level" reported in NHC's ACPI control panel, the "Actual Fan-Speed" is always ~2900 rpm, even under heavy CPU/GPU load.

I'm wondering if this might be part of my trouble? Perhaps the fixed fan speed is sufficient to keep things cool (~40 C) under normal use, but when I hammer the GPU (using "Video Card Stability Test") the fan can't cope and the temperature skyrockets to over 100 C (even with Arctic Silver 5, which incidentally made no difference in reported temperatures).

I receive no hardware errors or crashes, so it seems I'm not harming anything (yet), but such high temperatures seem like they'd be above the thermal spec for the GPU. The CPU is undervolted and rarely exceeds 65 C even under heavy load.

Tim,

I have just read your highly interesting investigations about lowering the GPU power-consumption/heat-dissipation - thanks a whole lot for sharing! Please keep up the good work! :thumbs-UP:

Unfortunately, I am not right now in a position to help you as my beloved T42p is dead for the time being :-( (and what is worse is that IBM/Denmark refuse to repair it, although it is surely covered by warranty; the whole sad story about this is described in the thread IBM/Denmark deny to honor warranty confirmed by IBM-Support).

However, one thing that comes to mind when reading about your troubles: What "Mode" have you set Fan Control to in in NHC; I mean the first selectable "Mode" which is displayed in Enable fine-grained fan control with NHC on Thinkpads; do you use "Manual" (1) or "NHC" (2) or "ACPI" (3)?? You could perhaps try (it's easy!) to switch the Notebook Fan Control "Mode"? Because I don't have my T42p here, I can't check what I do, but according to the thread T42 and ACPI in not working properly (see my post of Wed Sep 05, 2007 9:59 am), I am using "Mode" set to "NHC" (Mode = 2)... this seems to work for me and others - and as you see, I even won a beer from sharing that suggestion...! :-) Try it, Tim, and let me hear if that changes something?

PS: If you find out how to lower the GPU temperature (undervolting or whatever), there is surely a beer waiting for you here! :beer:

Best regards,

Johan

Thanks for this information; which I also just read now, quite a while after it was posted (read while I am badly missing my T42p so I could try this suggestion!). Highly interesting - can't almost wait to test this! Thanks, again! Where, by the way, did you download the ATI drivers from... perhaps here --> Drivers and software - ThinkPad T42, T42p, ATI Radeon/FireGL video drivers?

Best regards,

Johan

I have it set to "2:NHC" (and am using v. 0.82 of the script). In the next sub-menu ("Fan Settings"), I've experimented with "Fan Max Level" set to both "64=Max without EC control" and "128=BIOS ACPI control" with no appreciable difference in idle or load temperatures. I doubt that my fan is faulty, as it would be strange for it to work but only at a specific rotational speed.

This is a powerful motivator. :) My suspicion is that a software undervolting scheme should be possible and that would be a great feature to add to the next release of NHC.

Thanks,

Tim

Tim,

Thanks for your fast feedback about the NHC troubles; I very much enjoy your efforts and, yes, I keep the beer in the ''fridge for you.. :-)

Well, what I just came to think of is this: Would you like me to zip and mail all my NHC-stuff from my T42p 2373-Q1U (the program and all settings, XML and CSS files etc); I mean you could then simply temporarily rename your present NHC-directory, and try see if mine works better on your ThinkPad? If you want this, please let me have an e-mail address (you may send it via a PM). The whole NHC (zipped) incl. exe's is about 7 MB - that's not too bad for mailing, I think.

Best regards,

Johan

Thank you, Johan. That is most generous. I will give your script and settings a try in the next few days and report back. :)

Just a small hint; have a look in the thread T41p GPU Underclocking when AC - could be of interest to investigate the suggestions given there.

Best regards, and good luck with the testing,

Johan

^ Thanks.

I'm a bit behind in getting around to playing with the NHC fan control settings (work was insane this week). I'll post again when I've had enough time to investigate.
