The Lenovo Legion 5 15 Gaming Laptop, model number 82B5001AUS, ships with a 4CELL_60WH_INTERNAL, Lithium Polymer Battery, with a battery life of up to 5 hours, depending on the work the device is performing.

The Lenovo IdeaPad 1-14 Laptop, model number 81VS0001US, ships with Windows 10 S-Mode Operating System which includes Skype. Any other video conferencing APP compatibility will depend on the requirements and compatibility of that specific APP. We recommend you check with the software publisher's web site for their compatibility with Windows 10 S-Mode 64-bit operating system (Windows 10 S-Mode provides added security by only allowing APPs available ( and therefore certified by Microsoft) at the Microsoft Store. If you don't need the added security or you need to install APPs not available at the Microsoft Store, you can switch to standard Windows 10 Home 64-bit Operating System, at no additional cost.) and the minimum/recommended hardware requirements (Is a Graphics card required, the processor speed and the minimum required system RAM and the minimum available hard drive space) to run their program, then compare those requirements to this system's configuration.

The Keyboard is also wireless and connects via the same USB 2.4GHz WiFi receiver as does your mouse. The Keyboard, unlike the mouse, has a rechargeable battery. Use the included Mini-USB to USB cable to charge the keyboard. Plug the Mini-USB side of the cable into the front of the keyboard, then plug the USB end into a USB port on the computer, while the computer is turned on. You can use the keyboard while it is plugged in and charging. After approximately 2-hours of charging, you can unplug the keyboard and now use it wirelessly. You should get about a week's worth of life from a full charge of the keyboard battery under moderate to heavy use.
