You are correct, the Lenovo Yoga C740-15, model number 81TD0005US, ships with a 3CELL_60.3WH_INTERNAL, Lithium Polymer Battery, with a battery life of up to 15 hours, depending on the work the device is performing. If you are only getting 2 to 3 hours of battery life, first be sure that Battery Conservation Mode is turned off. This power management setting is used only when the laptop is plugged in all the time. It prolongs overall battery life by charging the battery to only 60-percent of capacity. Here is a link to instructions for turning off Battery Conservation Mode: https://support.lenovo.com/us/en/solutions/ht103159. Additionally, be sure any software you installed is compatible with Windows 10. Incompatible software will drain the battery at a higher rate. 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. Also, be sure there are no programs running in the background on your computer that you don't want running. These background programs drain the battery. Here is a link to information about how to find out what programs are running in the background on your Windows 10 computer and how to manage them for better system performance: https://www.windowscentral.com/how-prevent-apps-running-background-windows-10.

Sorry, there was a problem. Please try again later.My laptop also has the same problem. The battery life should last for 15 hours but it only lasts for 5 hours. Now, my microphone/ audio isn’t working either.
