Slim and portable at 0.83" thin, the 14" ThinkPad T450 Ultrabook from Lenovo is built with ports and connectivity options that are often found on mobile workstations. Designed for business productivity, this system is powered by a 1.9 GHz Intel Core i5-4300U Dual-Core processor that allows you to run multiple applications simultaneously. If you need more power, the processor can be overclocked to 2.9 GHz and the system's 4GB of 1600 MHz PC3-12800 DDR3L RAM allows the computer to quickly access frequently-used files and programs. The RAM comes in a configuration of one 4GB module installed in a 204-pin SO-DIMM socket. The SO-DIMM socket can support memory amounts up to 8GB and there is also a second SO-DIMM socket with the same specs, allowing the system to support a total of 16GB of RAM.

The 14" LED-backlit anti-glare display features an HD 1366 x 768 native resolution, a 16:9 aspect ratio, 200 cd/m2 brightness, and a 350:1 contrast ratio. The integrated Intel HD Graphics 4400 delivers a sharp, clear picture and you'll also be able to output video to an external display using the built-in Mini DisplayPort and VGA ports. For connecting to the Internet, a Gigabit Ethernet port and 802.11ac Wi-Fi are included. For connecting external peripherals such as storage or optical drives, this may be accomplished using the three USB 3.0 ports, one of which is powered for always-on device charging. Additional compatible peripherals may be paired using Bluetooth 4.0 technology.

For long-term storage of your files, the ThinkPad T450 features a 500GB 7200 rpm hard drive that allows access to your data. Whether you are listening to music, watching a movie, or playing a game, the dual integrated 1W stereo speakers with Dolby sound use the Realtek ALC3232 HD audio codec and offer high quality sound. There is also an integrated 720p webcam which allows you to engage in face-to-face conversations using Skype or other software, dual digital-array microphones, and a 4-in-1 media card reader that supports SD, SDHC, SDXC, and MMC cards.

The Lenovo ThinkPad T450 includes two batteries: a 3-cell/23Wh internal battery and a 3-cell/23Wh external lithium-ion battery. Together, these two batteries will last for up to 10.08 hours before recharging is required. The system runs using an included 45W AC adapter and while the installed operating system is Windows 7 Pro (64-bit), a Windows 8.1 (64-bit) license is included at no additional cost.
