Re: T400s random shutdowns

2010-01-17, 11:36 AM

So, after the very friendly and helpful Lenovo Technician came over and swapped out the motherboard in my T400s, I hoped my troubles would be over (though I did find it kind of worrying when he said that mine was the first T400s he had ever seen, and hadn't even seen Windows 7 yet). No chance, just had my first shutdown today, same as always...

I am sorry that this didn't help. But did you read this thread before that bad advice from Lenovo? Telling the customer to replace the whole motherboard is an advice they (and also other vendors) give when they don't have a clue. It is well known that this is a common problem that won't be fixed by exchanging the motherboard. Many people in this thread have already done the same as you did also without any success. Because you get the same problem motherboards in return.

I think Lenovo has not informed their warranty team what to do with the shutdown problem. It's rather the individual technician's decision to replace the motherboard.

Re: T400s random shutdowns

As a new owner awaiting the return carton for repair of my T400S speakers, I am hoping I do not experience the dreaded shutdown problem when it comes back.  Now the T400s is no longer on the Lenovo site.  Does this mean they have given up on the model and am I now the new owner of a lemon?  

 

Purchased this model for rugged business use and hope I am not plagued with ongoing troubles.  Should it be recalled and/or a replacement unit be offered if these T400s prove to be so unreliable?

They are pulled out from the website, as others have said, due to production delay. Along with T400s and T410s, some W series are also gone for now.

Warren - Particularly given that you are a new purchaser and are already sending it for repair of a problem with the speakers, I would strongly recommend that you return your T-400s. 

 

This computer is simply not reliable enough to be considered a piece of serious business equipment.

 

When (indeed, when?) we finally get some word from Lenovo as to their diagnosis and proposed fix for the random shutdown problem, you can then reconsider the machine. 

 

Under the present status quo, I would absolutely not buy this machine again.

Re: T400s random shutdowns

I purchased a T400s for evaluation and I experienced the random shutdown. I then found this forum and thread. Realizing this could be a major hurdle, I contacted my vendor. Below is the response. I hope this helps some of the people that are having this problem.  I was uncertain what to turn off for the advanced power management of the motherboard but I have turned off all the others and I am currently 2 days without a shutdown (including being on idle for about 24 hours).

 

Vendor response:

 

"I was able to speak with the Sr. Product manager for the T400 lines and the news is: they are aware of an issue and are working to push out a BIOS update to correct the problem. Lenovo recommended the following fix and patch until Lenovo can officially release the BIOS update. Please let me know if you have any additional questions. Thanks.

 

Go into the BIOS and turn off all the wake on LAN options for the NIC, the advanced power options for the processor and motherboard, and the Intel AMT remote management chip."

That sounds promising. And at least it is a suggestion towards a real solution that i really could believe as it points into the direction of the root cause of this problem because this problem and this solution / advice directs to hardware related problems and not to drivers / software / OS or whatsoever. So i could believe this is true.

 

What i wonder tho is what consessions are being made when they roll out the new bios to bypass the problems they have. We'll see.

 

Thanks for this info.

Warbow - I hope that works for you.

 

I can only wonder why the "Senior Product manager for the T400 lines" has not made the information about that interim fix available to all T-400s owners - and especially those that have specifically advised Lenovo they are suffering the random shutdowns.

 

BTW, a couple of days without a shutdown is not reason for optimism.  My current pattern seems to be up to 4-6 days without shutdowns and then as many as three shutdowns in less than 24 hours, followed by some more days without another.

I never experienced a shutdown (except one due to Windows update) probably because I turned off wake on LAN and Intel AMT chip in the BIOS.
