Up to Windows 8
Windows 8 gives you great support and user experience.
The 23" display takes surprisingly little space on your desk, counter, or entertainment center. The unit itself starts at a mere 55mm/2.2" thin, with clutter-free cable management and a sleek metal stand that allows you to store the keyboard underneath. Everything tucks away neatly when nobody's using the C540, even though those times will probably be rare.
Thanks to its HD graphics support, DVD reader/writer, stereo speakers with Dolby® Advanced Audio™ v2, and HDMI output, this PC offers crisp visuals and immersive sound for a fuller, more satisfying home entertainment experience.
Featuring a modern look and feel, the optional AccuType keyboard has island-style, ergonomic keys that allow a more fluid, spacious, comfortable and accurate typing experience than standard keyboard designs.
Integrated 720p HD Webcam with YouCam
Chat with family and friends with an advanced webcam software that tracks and auto-zooms on faces, enhances pictures, and adds cartoon effects to make the webcam experience more fun and interactive.
Lenovo's Dynamic Brightness System automatically adjusts the display's brightness to optimal levels dependent upon the level of ambient lighting, while Eye Distance System protects your eyes from strain or damage by emitting a warning signal when you are too close to the display.
Lenovo Cloud Storage
Protect your critical data, while also making access to information and file-sharing quick and convenient. Automatically back-up and synchronize data across the organization, while enabling access from multiple devices. Data is encrypted on transfer for an extra level of security.
Lenovo Rescue System
Quickly and easily backup and recover system files, applications, drivers, and even user files.
The family-friendly C540 includes a slate of nine interactive applications for children – puzzles, games, and flash cards – programmed to deliver a fun way of teaching numbers, letters, animals, time, and other topics.
Move data quickly between your PC and other devices with USB 3.0 – it's up to 10 times faster than previous USB technologies.
