Re: T400s random shutdowns

2009-12-02, 22:55 PM

My model is 2801-CTO, vista business 64 bit. I have not checked the bios version. not updated, should be 1.09.

 

I kept it for several weeks, but used seldomly because it is just for mobile computing.

 

This afternoon it suddenly shut down, like losing power or overheat, shutting down was from hardware electrical circuit, rather than software or OS issues.

 

I turned on again, by fingerprint, after about half an hour, died again. I noticed that this is not an accidental problem. On the forum, I found this 21 pages topic. What I found are:

 

1. This is not a software or OS issue. It is a hardware design problem or bios problem.

2. This is not caused by temperature overheating or unstable voltage from output of AC adapter or battery issues.

 

I also noticed that before the two shutting down, I both used fignerprint to turn on the computer. After the second shut down, I noticed this point and use power button to turn on. Until now, about 2 hours, it is fine. So my question is that Is this problem assoicated with fingerprint?

Thanks for your post Bill, be sure to add your details into the spreadsheet here -> http://tinyurl.com/ycdn73p

 

I wish it were associated to the fingerprint reader, but I almost never use mine and I get shutdowns... ;-(

 

In other matters (and I don't want to take this thread o/t), I resumed my T400s last night to be greeted with this:

Got the same thing this morning also! It goes away if I reboot.

 

Anyone experienced this type of video corruption before? It just keeps getting better...

Thanks for your collection. I will add later if it happens again.

 

Fingerprint is one of the switches that directly to the power switch(as it can directly turn on a computer). But your problems seem to have nothing to do with fingerprint. If it is bios' problem, what we can do is only waiting. Sigh.

 

This crash of screen happens only at this specific environment? I mean when you use Win+R, cmd, it also has this in a text-based enviornment? Or when you restarts computer, it keeps?

 

If so, I believe video card died.

Hi, well i have the same problem after resuming from sleep sometimes. It is solved already somewhere on this forum, it looks like it is problem with last display driver of intel, version 8.15.10.1968. All people reporting this problem have these problem after they installed this actual version of the driver (me as well). If you try to uninstall it and put previous version, there shouldn't be this problem (or just wait for new version). Second advice of somebeody is, that this might be the problem of conflict in older display driver and new one (did you have there previous ddisplay driver installed and you have made update to last one?). Then his advice is, uninstall in computer management completely the current driver (remove from laptop), restart and install from System Update drivers again (but do not know, if it really will help). May be just try previous version of display drivers.

Hi UberSteve,

I can tell you what this is. I had the same thing happen to me. It happens when you connect your computer to the power supply while its asleep and then resume it. If you revert back to the original Windows 7 Intel Display drivers (version 8.15.10.1749 ), the problem goes away.

As I noted in an earlier post, this "random shutdown" thread has been active for more than four months.

 

Having had three additional T-400s "random" shut-downs in the last 36 hours, I wonder

 

   - whether anyone has had a constructive, substantive response from Lenovo on any aspect of the random shutdown problem?

 

  - whether anyone has any indication that Lenovo has committed serious, qualified resources to addressing this problem?

 

   -  whether it is other than a reasonable expectation that the manufacturer definitively resolve such an issue in a "reasonable" time (which must, surely, be less than four months)?

Samtoossi, Thanks. FYI. I am running 8.15.10.1892 on Win 7 and have NO shutdowns.

I hear you RO-TPfor....this is fast moving into ridiculous territory! I wouldn't even expect this from Dell, let alone Lenovo!

Nop! I was getting PM responses from Mark_Lenovo for a while, but now he seems to have dissapeared!? My local Lenovo Customer Care Rep that's meant to be organising a replacement is taking forever and just told me "I'm processing this replacement machine as fast as i can,at this current stage we couldn't say that it's a known issue. Your machine will be tested by service centre to confirm on the issue,even though it's has been ongoing discussion in the forumn"

 

  - whether anyone has any indication that Lenovo has committed serious, qualified resources to addressing this problem?

 

Mark_Lenovo mentioned to me in a PM that he had witnessed the random shutdown fault and it turn send the system board to Japan for further analysis. Have heard nothing since...

 

   -  whether it is other than a reasonable expectation that the manufacturer definitively resolve such an issue in a "reasonable" time (which must, surely, be less than four months)?

 

It's TOTALLY unacceptable and is driving me MAD!  We should be offered a refund or a fix NOW!

 


 

 

If I don't get some good news next week from the Customer Care rep meant to be handling my case, i'm moving up the chain until I get some satisfactory answers! It seems to me that Lenovo have no clue what is wrong and are just trying to cover it up by leaving us in the dark.

 

-Steve

 

PS. Sorry all for the rant, but enough is enough! We are all trying different tests to help diagnose the problem, I take the initiative to start the shared Google Spreadsheet, you guys all take the time to fill it out, and what do we get in return, sweet FA!
