T400s random shutdowns

2009-07-24, 23:07 PM

I've got a brand new Lenovo ThinkPad T400s (NSDCVMN / 2808CVG), installed with Windows7 Ultimate 7600 64-bit, with all the latest Win7 drivers etc..

 

It has been working thrillingly from day one! It's much more smooth and performance overall better than my previouse SL300, along with the build quality being ten times better!

 

 

But sometimes it just shuts down? Just like that, there is no bluescreen, nothing it just goes black out of nowhere sometimes?

It's like the power just shuts for a second? It's not the battery being out, as when I turn it back on I've got plently left, it even happens when I got the power cord connected? I also got a UltraBay II battery in my T400s.

 

Any ideas what might cause this annoying problem?

Re: T400s random shutdowns

All,

 

Update - I'm editing this post to be the official solution, since it is the point in the discussion where we declared this to be a hardware defect that could occur in a percentage of the early vintage T400s systems.  Discussion continued after this post as we updated stocks and cascaded communication about this issue through all service channels. 

 

For the past several months, with the help and valuable input of everyone on this thread, we have been working to find the underlying common cause of these random power off events experienced by a subset of our T400s customer base.

 

We have determined that an internal noise issue with the voltage regulation component is the common element.  This is an electrical noise issue which manifests in a fairly small portion of the use base and does not appear to develop over time. 

 

As discussed at length here, some combinations of BIOS level, system settings, and driver versions can affect the frequency in which these random shut down events can occur, but these factors are not the cause themselves.

 

Component changes were made during the late November / early December builds and systems manufactured after this period should not be affected.  Updated service parts will be in stock shortly, are now available and if you are experiencing these random shutdown issues, we recommend that you seek service to have the system board replaced.  Uplevel service parts will bear 60Y and 63Y part numbers.

 

I would also encourage everyone with an existing T400s to update to the new version 1.12 bios regardless of whether or not they have experienced a shutdown issue in the past. 

 

A sincere thanks to UberSteve and others who have helped to organize the information and keep the discussion on track as many combinations were tried out. 

 

Best regards,

 

Mark

Has happened twice to me over the past two weeks, yeah seems like power goes out (both times was plugged in). Likely hardware (since it was instantaneous). Have a bad feeling about this pattern. (guess will wait for a recall) Otherwise, love the T400S. (CTO2801 P9600/3GB/128SSD/WiFi5150/no camera/no BT/Win7x32 RC7100)

Using a pre-release version of an OS.

 

Until you install a released and fully supported OS, you are not likely to get any useful support for the problem you describe.


Cheers,

Is not really a BETA OS, as I'm running the final RTM-build?

 

I doesn't seem to have anything to do with the OS at all anyway, so I don't really get why my thread was moved from the T400 section?

 

I've tried with Windows Vista Business 64-bit Service Pack 2 as well, with all latest drivers and the same thing keeps happening.

It feels like power just disappears for a split second, regardless of the power cord being connected or not?

 

As it keeps happening even with a different OS, and there is no  sign of the failure coming before it suddenly hits, no lagging, freezing or anything of any sort? No bluescreen or failure message, just the computer becoming dead in a split second, forcing me to power it up manually afterwards it seems to be some sort of a hardware problem?

What you have is Windows 7 RTM plus beta drivers and software.

 

RTM is the phase where the OEM's get to add their drivers and software, do their final tweaking, and create production images for the October 22nd Windows 7 release. Lenovo has made their beta Windows 7 drivers and software available to us, and is about to make available a new beta round.

 

Since you've now reproduced your problem with Vista, I'm going to move this thread back to the T400 / T500 and newer T series ThinkPads topic.

 

My advice would be to load up the factory Vista install and send it for warranty repair with a clear description of how to reproduce the problem.

USB-C: Just cos it fits don't mean it works.

Bit hard to describe how to reproduce the problem, as it simply happens out of nowhere.

It might happen early in the morning, mid-day, evening etc.

 

It has nothing to do with load either, I've tried Memtest86+, Furmark stress test, Prime95 and Intel Burn Test without any problems occuring. And suddenly while I chat on Live Messenger later the same day the computer just goes black and I have to power it up again.

Same problem here. Happened once. I have Windows Vista Ultimate x64 installed. It seems lost power instaneously (I had AC power plugged-in).

 

It seems this is not an isolated case. Can someone from Lenovo say something?

There is just one BIOS release currently available, so not really possible to do a update?
