Re: T400s random shutdowns

2009-12-15, 1:20 AM

I just would like to add my two cents. 

 

 I do not have a T400/T500 I own a T61 (Not that much different a system -just a little slower and older). 

 

Last week I undated my OS to windows 7 (x64) and my system ramdomly goes to sleep (Yes it happens while I am working and not just idle) for no reason on A/C power (only A/C). 

 

I tried many things updating my Bio's, Drivers, Lenovo software, changing bio's/power settings, etc.  I was coming to the same conclusion as others on this list that maybe my system was over heating.  The porblem never happened on battery power nor did it happen at all when I was running Windows Vista. 

 

I figure out one thing that may help others:  The problem started when I installed all of Lenovo's software "improvements" (you know the one's with all the lastest and greatest drivers and controls). 

 

So what I did was uninstalled the Lenovo Power Management Software and let Windows 7 manage my power settings. 

 

So far so good.  My system hasn't gone to sleep in a couple of days. 

 

Please let me know if anyone else has this problem.

Wesleyyin,
I have had the shutdowns while simply browing websites, drafting Word documents or even unattended when presumably no processor intensive activities are happening.  I have had some issues, not reported here, in which even when I put the T400s to sleep and in my bag for transport, it didn't really sleep and instead the fan was running hard trying to keep it cool in my computer bag. Not sure what it was doing then, but it didn't randomly shutdown either!

The random shutdowns are continuing with BIOS 1.11 for me. I now have Intel display driver 8.15.10.1872 and it shutdown today while docked and unattended.


Hello jsperson3. I have a friend telling that sudden shutdowns are possibly due to overheating intel chips. This partially explains why some lenovo running specific versions of intel drivers never see any shutdown. Do you recall running any graphics intensive tasks such as 3D, loading webpages full of flash vidoes, high-res vidoe, fancy screen savers, etc?

the shutdown issue is definitely not due to overheating . Shutdown have been reported while idle. Every since my t400s has been stable under the "1.11/1982" setup, I started using tpfancontrol to keep the fan off until it hits 65. I even pushed it into the 80s using prime95 and farcry running together. Still no shutdowns.On a side note, im amazed at how well heat is transered to the chassis. Most machines i've used (even other thinkpads), start buring right under the CPU when under heavy load. The t400s spreads it across the entire bottom of the machine, like a huge heatsink. Thumbs up to the engineers

 

Btw, Im undervolting this machine fairly low now too, and its rock solid.

 

I'm almost convinced its the intel drivers that are causing the shutdown

Uninstall the Lenovo Power Management and see if you still have the problem

On several occasionas I, too, have had the problem with putting the T-400s to sleep (or, rather, thinking I had) and finding it in my briefcase running...with the unit very hot.

 

And, of course, the random shutdowns continue.

I suggest add a column for Video BIOS version. It can be found in intel's video configuration interface by clicking on the exclimation sign.

 

Mine (no shutdown ever) is

 

Video BIOS: 1736.1

Mode: 1440 x 900, true color, 50 Hz

 

Other information is

 

Driver version: 8.15.10.1872

Vendor ID: 8086

Device ID: 2A42

Device Revision: 07

Well, i had random shut down as well, after BIOS update and intel driver reinstal (or update) i do NOT have shotdown till now. It is about 2 weeks without random shutdown. What is funny, i have new desktop PC with integrated Intel display and what is funn, random shutdowns occured on this desktop machine as well. it might be completely different reason, but it is really "funny", that it has same symptoms. I have upgraded intel driver as well on that desktop and it is without this random stud down symptom. May be this is really somewhere in intel drivers, but who knows, magic things happends sometimes. On my T400s Video BIOS is 1736.1, Intel Driver Version 8.15.10.1986
