You can pick these up pretty cheap if you spend some time looking. I bought mine on Craigslist for $120.00. It had a fried 9 cell battery and 3GB of RAM. I upgraded the RAM for $20.00. I picked up a genuine 9 cell Lenovo battery for 69.00.The laptop was in excellent condition once I gave it a good cleaning inside and out. It looks brand new actually.

openSUSE 12.3 64 bit on Lenovo T400 2767 2JU is a seamless install. Everything seems to work flawless. Have not tried to set up the fingerprint reader but I have no need to do so. Wireless is perfect. Display is nice. Switchable graphics work if you load the ATI drivers. FN keys all work, including Think Light and Blue Tooth.

Specs:

CPU T9400 2.53GHz.
HD: Seagate 250 GB hard drive
RAM: 6GB DDR3 1066 (4GB and 2GB SO-DIMM)Matched brand, timing, CL
Intel 5100 AGN Wireless adapter
DVD Burner

Hope this helps someone.

Thanks for the post.

Just a minor thing, with using different size RAM modules you force the memory controller into single channel mode, which will decrease performance. With equal sized RAM modules the machine should be faster (especially when you use the onboard video).

Other than that, nice machine.

No. It will run in asymmetrical dual-channel mode. It is as I verified it.

Dual channel mode is over-rated. If you're running many smaller applications simultaneously, unganged mode will be more efficient. If you're running one large memory-hungry application, dual channel ganged mode is better. I run my desktop unganged, for example, because I've usually got many apps open at once.

I agree. Generally, I prefer each core to have access to a stick of ram.

Unganged and ganged mode are two different modes of dual-channel RAM access. Running your system in unganged mode does not mean that you are not using the dual-channel capacities of your system.
