Betreff: T420s Fan noise Issue

2012-06-26, 12:38 PM

 

Gentlemen,

 

I do not have a 430s and do not have any outstanding problem with Lenovo. I do have four working IBM and Lenovo laptops and I never had an unresolved issue with either one of them. I must add, however, that the three issues I had in the past, one goes back to IBM's time and was addressed in an amazingly efficient manner, another was resolved by IBM as Lenovo's service representative in the foreign country where I was at the time and . Needless to say, this one was also taken care of with flying colors, not surprisingly, given my previous experience with IBM. The third one was about a battery that had died 13 months after purchase (or one month after its warranty had expired...). This one was also resolved quite efficiently in these forums by Mark, who used to be very much involved and competent at resolving problems in a fair and equitable manner.

It does seem to me that this last one year or two have witnessed Lenovo's free downfall from grace, and the way this thread has been going for so long like on an "automatic pilot" mode seems to corroborate my worst fears...

But, hey!... I wish I'm wrong!

Uninstalled my Display driver but the fan issue on this lovely machine is still loud as heck.  But thanks for the suggestion.

 

All my drivers, software, BIOS,...etc are up to date.  So basically I've done my part.  But Lenovo hasn't done theirs.

Even though the T420s has been replaced by the T430s, Lenovo should still fix the fan noise error.  Right......

Hi,

 

it seems Lenovo just sat the problem out. Did anyone notice that in the new T430s they did not offer a NVIDIA GPU in combination with an i7 processor anymore. It seems this T420s i7 NVIDIA was a design problem in the first place. Both components generate far too much heat for such a small design like the T430s series. The only thing I am unhappy with is that Lenovo did not have the guts to admit that in the first place...

I have an integrated graphics-only model with this issue, so I doubt it really is an i7 + discrete graphics problem.

No improvement here with all current available updates. 

The fan spins non-stop at a very high rate with absolutely no workload taxing the system.

My T420s sounds like a hair dryer.
