WINDOSW XP PRO ON T23, FAN ISSUES????

Message

larryb · #1 Post by **larryb** » Thu Sep 04, 2008 6:31 pm

I have a T23 that was working fine untill I installed Windosw XP PRO.

The old operating system was XP Media version (something like that), anyway This is my second T2X system and I am familure with the operations of the MB. After installing XP PRO the fan quit working.

It will come on during the POST, so this tells me that the fan is working but the bottom of the Laptop gets very hot in the area of the Hard drive and CPU and will cause the breakup ogf the LCD video. When this happens I pick up the laptop and let it cool on the bottom and everything is good until it gets hot again.

What measures the temps in the CPU and case area that triggers the fan to come on and shut down when temps are cooler???

Maybe it is just bad luck that the fan operation went south after the new version of XP, but I thought I read somewhere that XP drivers may keep the fan operation from working.

Anyone got any ideas???

Thanks in advance

I run WinXPP on my T23 systems and have never noticed this problem. They all have varying levels of BIOS and Embedded Controller versions. From memory, they will usually heat up to about 55-60C before the fan starts blowing. They idle around the mid-to-upper 40's (1.13Ghz and 1.2Ghz CPUs).

There should be a temperature sensor circuit on the motherboard which controls when the fan kicks in. You can test the function of the sensor and fan by downloading a copy of PC Doctor for DOS. One of my recent posts covers getting this program:

http://forum.thinkpads.com/viewtopic.ph ... 070#438070

Under the "Other Devices" menu heading there's tests for the fan and thermal sensor. Run them and see what PC Doctor says.

You can also download a tiny utility program called MobileMeter which monitors some of your system parameters (CPU speed and temperature, HD temperature, power):

If your fan problem seems to have appeared after you installed the OS then it might be possible that you do not have the proper APM/ACPI management software (just a guess). What kind of XP install disk did you use?

Not sure what you mean, but it was a original windows XP pro cd, purchased from Microsoft website.

I was just on IBM's website looking at drivers and updates/upgrades. Noticed PC doctor and was going to down load it and run it.

On my older T21 I had the same problem and after replacing the fan with another I just hard wired the +5vdc to the fan input and ran 100% of the time

I have not taken the T23 apart yet to look to loose coils, caps ect...

Thanks for the advice.

I am also running XP Pro on 2 T23's
One runs hotter than the other, but neither gives me shut down issues.
Both have Notebook Hardware control on them, while not directly controling the fan, the speed step down to 730MHz normally keeps the fan off. I have them both set up in Dynamic Mode for both AC and battery use. One peaks out about 65C before it gets drug back down to a more acceptable temp. The other one rarely gets higher than 60C. I dont really push either machine, but its not unusal for me to listen to music, have Outlook open and 6 or so other windows.
Try the APM/ACPI issue already mentioned, I have had it do off the wall stuff on desktops.
Worth a try

rkawakami,

I downloaded the PC doctor .ISO file that you made from the floppy disks. Tried burning the ISO file to a cd but it didn't work.

http://www.kawakami-ca.com/ibm_t2x/ibm_t22_pcdiag.iso

Is this a bootable cd or what am I overlooking here.

I Have tried it twice and still no go. What is the procedure for using this file.

Larry

.ISO file needs to be burned onto a CD using an "image" option in whatever program you use for writing CDs. In other words, you can't simply write the file onto a blank like any other normal file (.doc, .mp3, etc.). The resulting CD is bootable.

OK, it worked and was able to run the tests. the fan test worked at 50% and 100% fan speed, the thermal test passed.

Sooooo, does this mean I don't have a problem???

I looked at the other utility program you suggested to check hd and cpu temps, but I don't think that will help me get the fan to work and cool down the cpu/hd areas.

Any suggestions?????

Larry

Well, the PC Doctor test results basically tell you that the hardware is functioning the way it should. That leaves the software component. The MobileMeter program will only allow you to monitor the temperature so you have some data to analyze the situation. It cannot actively control the fan. The Notebook Hardware Control (NHC) program that jronald mentioned is designed to do just that.

Have just read this thread and here is my 2cs.
Your symptom is video break up and you suspect it is temperature related.
Installing XP will set the default power option. Unless you change this to Portable/Laptop the cpu will not step down to 733 and generate less heat.
Having already established that your fan is able to work I suggest you install MobileMeter to monitor the actual temperature you are getting up to. It may not be excessive, you MIGHT just have a temperature related LCD or video issue.
The IBM power management software is worth installing to override XP settings as is the video driver.

As a further thought does the video break up on an external monitor too ?

I would like to know if you did install all the IBM/Lenovo drivers and utilities.
Sounds like you may not have done so!

I have not loaded any IBM drivers. I know there are some on the IBM website, but wasent sure which ones to download and install.

Change the TYPE number as per yours and get drivers here

Well I found out the problem with the LCD screen breaking up. It's bad, came home today and the wife tells me the screen now just goes blank. Took a look and hooked up a external monitor and sure enough the video is there but not on the screen.
I just happened to have the older T22 sitting on the shelf and now it is less the LCD screen and the T23 now is working.

God, I hope this is it.

IF MOMMA AIN'T HAPPY THEN NO ONE IS HAPPY

I will down load the Power management drivers and the video driver as suggested.

Thanks again.....

I see the power manager, but do you have a date on the video driver or is it part of the power manager?

Thanks again, I was aware of the link from my t20 experiences.

Hope I dont need it again for a long time.....

Thanks for your help.
