Re: Brand new Lenovo ThinkPad T400s (NSDCVMN / 2808CVG) suddenly shutting down?

Same here, it keeps happening regardless of whether the main battery is connected, fully charged or dead.. With or wihtout the AC-adapter, also with or without my UltraBay II battery.

 

 

I'm now trying to deactivate  the Intel AMT,I have nothing better to do so why not try it?

 

 

 

To me it sounds like TexasTea400 have a somewhat different problem than me, might be a connection of some sort but first of all I've got the T400s, he got T400.. I suspect there are some differences in the hardware and mechanics of the two? But I've got absolutely no software instability issues, my computer simply power of about  3-4 times every day, but TexasTea400 seems to have a somewhat different problem with bluescreen and instability etc.. before the power down hits? My problem is completely random and there is simply no sign of any kind of instability before, during or after my power disappears.

I think that the blue screen was not related, RamGuy459.  It happened once and that was two days before my first shut-down.  I have not seen it again in the suing 5 or so shutdowns.

Let me chime in again. I think we can all agree that this phenomena is equivalent to a momentary loss of power (to simulate take out battery and just for a fraction of a second unplug the AC). Many of you are having this happen fairly frequently. It has happened to me just twice in the past two weeks. I'm guessing that others who experience this only v infrequently (1-2x per month) won't be reporting this. I'm of the opinion that this is a significant hardware issue, and Lenovo needs to act fast given these are its top of the line systems. Anyways, just upgraded warranty to onsite as I have a feeling I'll be needing it...

No good in deactivating the Intel AMT, lost power during the night.

Brand new Lenovo ThinkPad T400s (NSDCVMN / 2808CVG)

2009-08-03, 11:38 AM

Hi RamGuy459

 

I would like to buy a thinkpad T400s 2808 in France, but it's impossible to have the exactly information about the T400s.

All thinkpad T400s 2808 on the french web have the T400 picture with an old interface and don't have the US size.

 

Before buying this one, i would like to know if the 2808 is the slim thinkpad with the last fonction.

 

Could you say me if your 2808 :

- is the Slim thinkpad (0.83 inch),

- got an Individual Microphone Mute and Speaker Mute with LEDs

- got a larger Touchpad with multitouch

- Larger Esc and delete button.

Thank you for helping

Yes, yes, yes and yes on all those questions :)

 

 

For the fun of it I just ran memtest86+ test booted from DVD to prove my point in this not being a operating system related issue, and the power loss suddenly occur after a while with memtes86+ as well.. So obviously it's something fishy with either the hardware or BIOS.

Well, this has continued for me at 2-5 shutdowns per day since  6 days ago.....  Mine must be some kind of active shutdown involving Windows (I've noticed a second or less of something happening as the app I'm in loses focus).    Get this:  when I power up, I found that my desktop settings had been altered.   I've had the icons put on the grid, where my normal case is not.  Also, my screen resolution was changed. 

 

Is there a Hardware/T400 level and/or Windows logging capability  that I can turn on?

I noticed there is a new BIOS release available for the T400s:

http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-72823

 

Will give that one a try! Nothing in the release notes regarding this power issue, but my hopes are up!
