Support mobile productivity with the Lenovo ThinkPad T400, a 14.1-inch business notebook designed for professionals who need dependable performance away from the office. The Intel Core 2 Duo T9400 processor and 2 GB of memory handle routine multitasking, while the 160 GB hard drive provides local storage for working files and applications. The 1440 x 900 display gives the workspace more room than standard WXGA panels, which helps when reviewing spreadsheets, documents, and multiple windows. A Super Multi-format DVD drive adds flexibility for optical media, and built-in Bluetooth, Gigabit Ethernet, and IEEE 802.11n wireless support keep the system ready for varied office and travel environments. Lenovo’s ThinkPad design language is about durability and practical use. The roll cage and shock-mounted hard drive are there to protect the investment during frequent travel, while the fingerprint reader adds an extra layer of access control. With up to 9.80 hours of battery life, this configuration is suited to users who need a notebook that can stay productive through a full workday without constant charging.
