A:Answer The Yoga 7i-15 has only been available since October, 2020. If you have the earlier model, the Yoga C740-15 and its battery will not charge, first, let the battery drain below 50-percent charge capacity. Then plug in the charger and see if the battery will begin charging. If not, restoring the computer back to original factory settings may reset the battery also, allowing the battery to once again take a charge. The Lenovo Yoga C740-15 is equipped with OneKey Recovery System. There is a very small pin hole on the bottom right side of the device, right near the top right corner of the cooling vent on the bottom of the device. You will need a pin to push this reset button. Plug the device in. Let the battery charge for about 15 minutes. Push the reset button. The system should boot to a choice screen where you can choose "Restore To Factory Default". Select this. It will delete everything from the hard drive except the original factory install of the operating system. You will need to reinstall all programs and files after the reset. If you don't have copies of the files, try to make one before you restore by selecting "Boot to desktop" and trying to back up your files. If the problem persists after the factory reset, we recommend you contact Lenovo Tech Support at: 877-453-6686. Also confirm your coverage with Geek Squad if the reset does not fix the issue.
