The T400s includes all the features you would expect in a business laptop and then some. Theres a fingerprint reader for added security, so only people whose fingerprints are registered can authorize Windows to boot up. The optional 2-megapixel Webcam is ideal for videoconferencing, and it delivers accurate colors and a very good image even in less-than-ideal lighting conditions.
As for expansion, the T400s sports two USB ports, a combination USB/eSATA port (for connecting a fast external hard drive), plus a VGA connector and a DisplayPort connector for sending the video signal to an external monitor or projector. Lenovo makes you choose whether you want an ExpressCard/34 slot or a memory card reader, as there isnt room on the thin chassis for both.
Lenovo offers a range of hard drives for the T400s, including 120GB and 250GB traditional drives or cutting-edge 64GB and 128GB solid state drives, which use flash memory for increased performance and crash-proof reliability. The modular bay on the T400s can be used for the multi-format CD/DVD burner that comes standard with the system, or you can opt for a Blu-ray drive or a second battery for that slot.
Given the array of standard and optional wireless solutions on the T400s, you should have no trouble connecting almost anywhere you go. The machine comes with fast 802.11n Wi-Fi, and Lenovo offers a Bluetooth option. You can also request an embedded wireless broadband solution with nationwide service from AT&T or Verizon, so you can connect to the Internet at 3G speeds without having to find a Wi-Fi hotspot. More impressive is the optional Lenovo Constant Connect ExpressCard ($150). It automatically syncs your T400s mail file with your BlackBerryeven if the laptop is powered off.
The T400s can be ordered with either an Intel Core 2 Duo SP9400 processor (running at 2.4GHz) or the slightly faster 2.53GHz Core 2 Duo SP9600. Combined with the 2GB to 8GB of RAM the system supports, those processors deliver plenty of power for typical computing chores as well as more demanding multimedia work. Graphics horsepower comes from the integrated Intel GMA 4500MHD solution, which is fine for video and light-duty 3D applications, but you wont want to be playing high-frame-rate 3D games on the T400s.
In our trials, the T400s delivered about two hours of runtime while playing a DVD continuously. In normal use with power-saving settings enabled, you can expect almost four hours of computing time; if you need more, you can opt for a second battery. Importantly, we found the T400s to be near-silent in operation, even under heavy workloads, which is an accomplishment for a machine this thin.
The T400s comes standard with Windows Vista Business (32-bit) as the operating system. If you prefer, you can configure the machine with Windows XP Pro, Vista Business (64-bit) or Vista Ultimate, which qualify you for a free upgrade to Windows 7 when that new operating system arrives late this year.
Lenovo also preloads its handy Productivity Center 3.0 and Rescue and Recovery 4.2 utility suites, which help you configure and maintain various aspects of your notebook. A one-year warranty with 24/7 tech support comes standard.
The ThinkPad T400s has a starting price of $1,599. Thats no budget entry, but given the standard features, the price is reasonable. If you travel frequently and want the thinnest, lightest no-compromises laptop available, the T400s is worth every penny.
