Embedded Controller update (which is included with the BIOS update) for my T400

I have a T400. That's all I know.  I'm supposed to dwonload one of these two updates. 

 

 

ThinkPad                                              Package version     BIOS version              Embedded Controller version 

 

T400 (with IEEE 1394 models)        3.09-1.05                  3.09 (7UET79WW)     1.05 (7VHT15WW)

 

or a

 

T400 (without IEEE 1394 models)   3.10-1.05                 3.10 (7VET80WW)      1.05 (7VHT15WW)

 

 

How do I know which one?   

 

This answer didn't come with the download directions so a non-techie (me) cannot go further.

 

Please help me with this.

 

Thank you,

John

This is about the Fireware interface. Check in your Device Manager if you have a driver for it. And/or look on the sides of the notebook for a connector labeled 1394 or Fireware.

Re: Embedded Controller update (which is included with the BIOS update) for my T400

Thanks, Nap.

In Device Manage I found a USB plug icon with the label IEEE1394 Bus host controllers
and inside that
RICOH 1394OHCI compliant host controller.
so I assume I should download this choice:
T400 (with IEEE 1394 models) 3.09-1.05 3.09 (7UET79WW) 1.05 (7VHT15WW)
Correct?

Yes, that Ricoh thing is the Firewire adapter, that's what I have on a T510 too. If you have a driver installed for it then it exists. So the logical thing would be to pick the optiion *with* IEEE 1394.

Hi johnslenovo,

 

To check if you have 32 bit or 64 bit Windows installed do check our KB Article on this.
