The Lenovo IdeaPad 1 14 Laptop, model number 81VS009GUS, is an entry-level configuration. It ships 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. This model ships with 5G, 802.11ac WiFi frequency capability. We recommend you check with the specific APPs software publisher's web sites of the specific APPs you will be using, for their compatibility with Windows 10 S-Mode 64-bit operating system 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 Lenovo Yoga C940-14 model number 81Q9002GUS, ships with the 4-Core/8-Thread 10th Generation Intel Core i7-1065G7 processor, with an energy-efficient base speed of 1.3GHz and a Turbo Boost Speed of up to 3.9GHz. The user does not need to do anything to access the Turbo Boost speed of this processor. The system workload determines the processing speeds. With the 12GB DDR4-3733MHz RAM paired with the 512GB M.2 NVMe solid state hard drive, this configuration is extremely fast with boot up, accessing files and programs. The Yoga C940-14 also ships with 6G Wide-Range/High-Speed 2x2 802.11AX WiFi capability. If you are getting slower than expected performance, be sure any software you installed is compatible with Windows 10. 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.
