Re: T400s random shutdowns

2010-02-02, 14:29 PM

I just don't want to waste my time with parts replacements that won't help, especially if the reasoning is not sound. Mark_Lenovo or someone else may have a simple answer to my question and I promise to shut up in that case. Talking about the dead horse: I got this machine mainly to travel around and give presentations, so I really need a satisfying solution...

Since the part stock is now updated with a new revision of the part, and parts stocks are being refreshed, I am confident in recommending a system board replacement as the definitive fix for these symptoms.


Mark,

 

The only thing i am still missing in all this info...... Why can't you tell us from what revision number upwards this new voltage controller chip is fixed? That would clear out difficult communication with 1st level support in Europa when we call for replacement......

 

Thanks, Jan

Re: T400s random shutdowns

Further to my previous posting on here pointing out that we were about to purchase 6,000 T400s machines by Jan 31..... it is unfortunately, Lenovo, as they say "too little too late".

 

I can see from the past few weeks postings that the level of user frustration is still high - especially as the worldwide Help Desks are still denying the existance of the problem and that the fix as detailed by Mark_Lenovo does not seem to have been communicated to the field ops in any meaningful way. Frankly, when you think about it - that is an alarming concept all on its own. Lenovo care so little about the users that they don't efficiently accept responsibility for an issue by communicating the issue and its resolution to world wide field ops overnight....!!! Astounding - truly astounding...!!

 

As a result of the shocking officlal response by Corporate Lenovo and despite Mark_Lenovos' best efforts on this board - for which I unreservedly and loudly applaud and congratulate him - KUDOS Mark - you are a great advert for the better parts of your company and a true professional who has done everything you can to help us with this sorry mess - Lenovo are not worthy of your skills, dedication and passion....!!!

 

Anyway.... as a result of this shambles..... Dell gets the order for 6,000 laptops.

 

We would NOT consider the T400s a machine worthy of the old IBM Thinkpad genre.

 

Until next time folks..... if there is a next time for Lenovo, that is...!!

 

Best wishes on getting your T400s fixed with minimum hassle..... and sorry we could not do more to get maximum corporate attention focused on this issue.....

This thread cracks me up.... feel the love...

 

My T400s seems to be OK.  I had this shutdown issue once after hibernation.  Set Sleep to Never when plugged in, and I have been good since then.  No other issues at all.  Love this box and it's new design.

 

On a side note, I am going to call BS on c4s_tf_porker's latest post.  6000 laptops to Dell over Lenovo?  Yeah right.  My guess it this guy couldn't get a PO for 6000 pencils let alone laptops.  If he has that much juice, there are other channels he/she can use at the corp level for this kind of stuff.

c4s_tf_porker: 

 

I respect your decision of 6000 Dell over 6000 T400s. I would point out that although this forum is a good place to discover problems of T400s (such as random shutdowns and failed speakers), it is not an appropriate place to assess the severity of the problems. It is not clear what the percentage of T400s units have the shutdowns and how often they have. While it is certainly true that those who are troubled by multiple shutdowns are quite frustrated by the shutdowns, it is also true that there are guys like me who don't see any shutdowns. (I had one due to MS security update) Those who don't see shutdowns happening won't visit this post or forum.

 

It likely seems that the random shutdown is a common problem of the early batches of T400s. I am not denying this. However, T400s has many attractive features too. If I were to make a purchase decision, I would consider the shutdown problem as part of the trade-off, or more precisely, the uncertainty now that Mark has said replacement of MB will eliminate the problem.

Re: T400s random shutdowns

My laptop has not suffered shutdowns for the last 1.5 months. There were few shutdowns in the beginning (4-5 months ago). It has stopped suddenly. The only thing I had done was kept updating Bios as it appeared in Lenovo's website. I am using my laptop 8-12 hours a day. I am not sure if I should seek a replacement of motherboard or not.

 

Is the nature of the problem is such that it is going to get worse with the age of the laptop?

Well, after BIOS update to last version in Dec 2009 i had 1 month and something without shutdown and i was almost glad, that it has solved problems, but the again, shutdown. And second, plastic cover has crack on left bottom side, above the HDD place (it is discussed somewhere here on the forum, looks like T400s has also physical design issue). I have sent my T400s to service yestarday so i will see what will happend.

Sagar_C,

 

We don't believe the situation will get worse as a factor of time.  The tolerances of some of these voltage controllers varied aparantly, and as we've seen here, BIOS level and some system settings - drivers, VT, etc did seem to change the frequency of these events..  The 410s models will not be affected, and all current T400s production will be free of this as well.

 

What to advise you?   I would say, if you have the shutdown event again, seek service and get the board replaced. 

 

I would also recommend that you upgrade to BIOS 1.12 if you have not - this will safegard your audio in the event of a power off.

 

Best regards,

 

Mark

Hi,

I have a t400 since November 2008. It worked all right with win XP. Around November 2009 I installed win7, and since then had a BSOD or hangs about once a week. BIOS upgrades didn't help. Lately, after some driver updates, I had a crash every day.

 

3 weeks ago, I opened the bios setup after reboot, and practically disabled every "smart" feature like CPU optimization, power optimization, etc. Since then I am now running 3 weeks, with no random shutdown :smileyvery-happy:. If there will be demand, I will post the full list I changed. I clearly do not know yet which item or combination of bios entries has done the trick, I may find that over time.

 

The only side effect is that by battery now lasts 4 hours instead of 6, but without shutdowns - I will live with that.

 

Amir

Ok, I am taking a shot. Monday they will exchange my motherboard. I have on-site warrenty. I asked them if they were aware of the problem, but the weren't really. We're talking netherlands here. So i explained the whole thing including Mark's comment about possibly older motherboards in stock. And told them i didn't want an old one because of the reasons the problem is only fixed in recent revisions.

 

So he checked and they first wanted to exchange my MB with a similar one. It was a revision number starting with 34 or something like that. But they couldn't find one anymore so i get a brand new one, most recent they saw till now, which starts with the numbers 60. They aren't aware of higher revision numbers. So let's hope this is a recent revision which has the problem fixed!

 

Mark, do you know if this is a revision number with the new voltage controller?????
