Thinkpads Forum

I just received a T400 6474-B83 as a replacement for my T60p that died due to heat buildup in the hard drive. I can't find this model in any tabook, and I also can't find any kind of owner's guide for the T400 (just a start guide that doesn't go in depth about any of the laptop features at all). So I am turning to the forum users for help.

The bezel plate on my T400 looks like this:

What is the 3rd icon? I thought it might be for WWAN, but I'm pretty sure my T400 doesn't have a WWAN chip in it. Here's everything that shows up in my device manager:

Any ideas? Also, is there a thorough user's guide somewhere?

How can I find out if my LCD is CCFL or LED backlit?

Thanks a lot!

That is definitely the WWAN icon. Either you model is WWAN upgradeable or the clear plate is a mistake. If it's a mistake and under warranty, you can ask for a new one. They'll send you a bag with several varieties (Bluetooth, WWAN, etc.), you can install the one you like.

Thanks for the responses and info. I guess this is a base model T400 with upgraded optical and hard drives. It'll have to do until I can get a T400s or X301.
