Unknown Product Number T420

2011-06-04, 10:05 AM

Hello,

my Thinkpad apparently does not exist. The product number cannot be read by Internet Explorer and it neither can be found when clicking through the menu's. It should be a 4238-A71, but so far I only found a 4236-A71 T420 in the menu.

This is most annoying, as I lack some drivers in Win7 and do not know which one.

It would be nice if anyone has a suggestion.

Best, Jochen

You can use System Update 4 to significatly simplify driver obtention and installation:

For reference, here is the old style T420 driver matrix:

Hi brc,

 

Does the system also say 4236-A71 on the back sticker? Please post a picture (make sure it doesn't contain S/N), I'll raise this issue with lenovo.

 

Let us know.

I am afraid this will take some time, as I do not have a digital camera. But I can assure you, that on the sticker on the bottom side of the notebook is written:

 

TYPE 4238-A71   followed by the serial number

PRODUCT ID: 4238A71

SOME KIND OF BARCODE

 

I will post the picture as soon as someone owning a camera comes my way.

Here is the picture.

product tag

 

I have checked the lenovo support page http://support.lenovo.com/en_CH/ again, but still my product code is not listed. Automatic detection in IE9 does not work either.

Hi Jochen!

 

There are a couple of things going on here. 

 

First the Lenovo support site is going through a major redo, and some data migration glitches are still to be fixed.

 

Second, historically not EVERY single exact product number has been listed on the support site, but that's not a cause for worry.

 

You'll find that the drivers listed under the model number (the first four digits of the product number). Here's the support page for model 4238.

 

If you're looking for driver updates, as The Colonel said you can also run ThinkVantage System Update, which will detect them automatically for you.

 

Hope this helps!

USB-C: Just cos it fits don't mean it works.

There are gaps in the model numbers. i had it with my T410s

 

What you can do is find out the nearest model that is similar to your configuration, especially one that match your HDD and graphic card. copy down the number.

 

next either go to lenovo and ask them to change d model number or you download a program on lenovo support, look under the T420 and bios section. burn the program on a cdrom, bootup into this cdrom and change the model yourself. It is relatively 'safe'. , just remember to backup your important stuff. And oh yah its good to be still in warranty just in case

It is highly likely that the A71 part of that MTM is a CMV (Custom Model Variant) build. 

 

A CMV are "a special bid offering. Therefore, it is NOT generally announced".  The on-line resouces may or may not recognise the specific configurations of a CMV, but the first 4 digits of the MTM which indicated the base (model type will get you onto the correct model base for driver/support purposes.

 

Cheers,

 

Bill

I got an email from lenovo's feedback team, they wrote they'll add 4238-A71 on their eSupport website, keep your fingers crossed :)
