Customer Ratings & Reviews

Thank you for choosing the lenovo Yoga C940-15. The Yoga C940-15 is configured for maximum computing power, but still is an ultra portable, 2 in 1 format device, weighing only 4.18 lbs. There is an internal fan to maintain the proper operating temperature of the system that works automatically, based on the system workload. At maximum workloads the Yoga C940-15 will feel warm to the touch. As long as you have the computer on a flat surface and leave space for the air to flow through the keyboard area and out through the bottom cooling vent, the internal fan will maintain proper operating temperatures. Because this is a high performance configuration, it uses a 135W external power supply and has an onboard 4CELL_68WH_INTERNAL, Lithium Polymer Battery, for up to 12 hours of battery life, when working remotely. Every component of Yoga C940 was engineered with your experience in mind. That’s why the Yoga C940 offers the brilliant color and clarity with ultra-narrow bezels, with 500 nits brightness, it’s 50-percent brighter than standard SDR displays. You’ll enjoy amazing realism that's vivid, nuanced, and powerful. Capture your ideas the moment inspiration hits with a garaged digital pen. Featuring an in-body charging compartment, the Yoga C940 ensures you’ll never lose a thought—or your digital pen—again. The convertible hinge hides a powerful Dolby Atmos Speaker System that immerses you in 3D sound in every mode. Combined with two sets of speakers featuring powerful subwoofers, custom tweeters, and unique vibration buffers that reduce unwanted noise, your audio will sound bigger, deeper, and more accurate. Experience how the Yoga C940 embodies world-class craftsmanship, innovative solutions, and elevated design. Log into your Yoga C940 in less than two seconds with an integrated fingerprint reader. That’s three times faster than the average time it takes to type a password. Forget your password.

The Lenovo Yoga C940-15 will get warm to the touch when it is under heavy workloads. If you are feeling the computer get warm under light to moderate workloads, first, be sure any software you installed is compatible with Windows 10. Incompatible software will increase workload, thereby increasing the system heat. There is no need to install Microsoft Office software. The software is already part of the operating system, you just need to activate the software with a purchased product key. If you have installed a copy of Microsoft Office, this is conflicting with the existing copy on the system and this will slow your system down. If you have installed a 3rd party anti-virus program, be sure that Windows Defender is turned off and that the trial version of McAfee Anti-Virus software is uninstalled. There can only be one anti-virus program on the system. You may need to restore your system to original factory default settings if any of the programming errors have occurred. You can do that by typing "restore" in the Cortana search window. Just click on the magnifying glass icon at the bottom left of your Windows 10 Desktop. Click on "Reset This PC" Then click on "Get Started" and follow the on screen directions to restore to factory defaults. If the problem persists, we recommend you contact Lenovo Tech Support at: 877-453-6686.
