We are sorry to hear that you are having issues with your Lenovo IdeaPad S340-15 Laptop, model number 81QG000DUS. This configuration ships with a 3CELL_52.5WH_INTERNAL, Lithium Polymer
Battery which, within this configuration, has a battery life of up to 10 hours, depending on the work the device is performing. If you are getting substantially less battery life, first, set your screen brightness at less than 100-percent - try 80-percent to start with. Then, be sure Battery conservation Mode is turned off. This power management setting should only be used when the laptop is plugged in all the time. It will prolong overall battery life by only charging the battery to 60-percent of capacity. Here is a link to instructions for turning off Battery Conservation Mode: https://support.lenovo.com/us/en/solutions/ht103159. Also check what programs are running in the background on the computer. Be sure only the programs you want running in the background are. These programs will 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. Then, finally, be sure any software you installed is compatible with Windows 10. Incompatible software will drain the battery at a faster 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. Regarding the webcam within your IdeaPad S340-15, this model ships with a 720p (HD) webcam with manual Privacy Shutter built in. Be sure the Privacy Shutter is completely open before trying to use the webcam or the webcam will not operate. There is a small slider, directly above the webcam lens. Move the tab to the right to open the Privacy Shutter. There is a red dot over the webcam lens that will disappear when the Privacy Shutter is fully open. This will indicate that the webcam is really to use. You can close the Privacy Shutter when you are done with the webcam for your security, by sliding the tab to the left to close the Privacy Shutter. The Red Dot will appear over the webcam lens when the Privacy Shutter is closed. If the Privacy Shutter is open but the webcam still does not function, now check to be sure you have the latest version of Windows 10 on the computer. Then update all BIOS files and drivers up to that latest version of Windows 10. You can easily accomplish this by scanning the computer with the Lenovo Utility software available on this computer. This system has Lenovo utilities installed to help maintain the health of the device and keep the operating system software up to date. Type "Lenovo Vantage" in the Cortana Search window (if Lenovo Vantage is not installed on your device, you can download the APP and install it now). Select Lenovo Vantage from the list. In the window that opens, click on "Health and Support". In the expanded menu, select "Hardware Scan" In the window that opens, select "Run Quick Tests". This will scan your entire system for errors. Follow any directions that may pop up. If the problem continues after this scan, now click on "System Update". First select Windows update from the menu. Scan your system to be sure you have the latest version of Windows 10. Once that scan is complete, select "Additional Updates". This will scan your device to be sure there are no new BIOS/Driver updates needed. Follow any instructions that may pop up. If the issues continue, we recommend you consult with your local Best Buy Store's Geek Squad about the cost of repairs.
