Take a load off
Our thinnest, lightest T Series notebooks ever start at just 3.91 lbs. and .83 inches thin so you can do business on the go.

Industry-leading battery life
Business can't wait for your battery to charge. Get up to 18 hours when you add a Slice 9-cell battery (available on T410 and T510 models) for all-day computing.

Work longer with energy-saving features
- Lenovo Battery Stretch lets you make temporary selections in extreme situations to extend battery life.
- Switchable graphics on T410s lets you move to lower-quality graphics when you need to maximize mobile computing time.
- Integrated graphics reduce power consumption by using graphics already onboard the Intel CPU.
- Solid-state storage drives use less battery power and create less heat.
- Optical disk drive and audio automatically switch to a low power state when there's no activity.

No-compromise performance

Picture-perfect viewing
T Series laptops give you superior graphics performance.

Switchable graphics let you power-up stunning graphics for important presentations, then power them down to preserve battery life. And they're easy to use. Just hot-key between Performance and Power Saving modes, or switch via the software user interface. No reboot required!

LED backlit displays are mercury-free and generate 25% brighter displays, boast crisper colors, consume less power and weigh 70 grams less than conventional CCFL displays. Use the wide dimming range to reduce brightness while still experiencing a clear display in dim environments.

16:9 aspect ratio on T510 models gives you an enhanced viewing experience.

DisplayPort video port (on select models) lets you attach a high-resolution digital DVI monitor using a DisplayPort connector. Use this next-generation display interface technology for everything from notebooks to monitors to TVs to projectors.
