I sent a PM to Mark_Lenovo in order to give us an update and of course he does not answer.

In the future I will no longer consider Lenovo products...

Did anybody try out the new 1.33 BIOS that was released a few days ago ?


Does it make any difference ? The embedded Controller is flashed from 1.12 to 1.19 during this update.

Hy yes I Intalled 1.33 right now and for me it is like 1.31. The testig with the mini dog and External Monitor commes later. 

But my Fan works with the 1.31 Bios  so that's not the same situation.

I would like to say that the 'fan issue' has been resolved in the T430s, but we aren't happy.

See this thread,

This is my second DOA with Lenovo. I hope the next replacement is perfect and issue free so I don't ever have to deal with Lenovo again.

Soduku - Ouch!  Looks like the T430s is off to a rough start.  That sucks (hope things get fixed for you), but reinforces my decision to stay clear of Lenovo after my T420s experience. I also noticed 2 pages of messages over there and nothing from Lenovo.  Mr Social Media only seems to like the tablets.


I'm looking at S_msung and D_ll for my next business laptop purchase.  What a shame - I'll miss the little red dot in the middle of my keyboard!  Come on Lenovo - right the ship please!

Went with Samsung and currently waiting for my Series 9. News on the quality of the T430s makes me happy of having moved away from this nonsense.

Betreff: T420s Fan noise Issue

2012-06-26, 8:15 AM

This is definitely my last Lenovo device. I do not longer recommend them to anyone. Essential argument for me is the lack of desire to solve the problem ultimately. Second is the evident low quality of soft- and hardware testings, before products were offered for a lot of money to the customer.


Many thanks to alexcriss and all other committed persons for arguing, testing and their long haul.
