Hello, cboy39. We are sorry to hear that you are experiencing this issue with your Slim 7i. Apologies in advance for the length of this response, as we want to solve this issue immediately. Here's the steps to help resolve your battery life issue: First, on your Taskbar at the bottom of the screen, type into the search box, “Lenovo Vantage”. After the application populates in the search, select it to open the application (it should have a blue “L” in a square as the logo). If you haven’t used the application before, it may require some setup. Follow the on-screen prompts to set up the application to your preferences. Upon setup completion the home screen of the application should show things such as: a button labeled “Check For System Updates”, or “About My Device”. First, we recommend selecting the “Check For System Updates” button and applying any available updates to help ensure that you are running the latest software, as system bugs or inefficiencies can affect battery life. After applying updates, your system may need to restart. After restarting, reopen the Lenovo Vantage application. This time, along the top of the application, there are several tabs listed. Select the tab labeled “Device”. Under this tab, the section “Power” is what we are after. In this tab you can utilize something called “Smart Power”. This allows you to toggle the thermal and performance profile your is set to ranging from battery saving, intelligent cooling, and maximum performance. These profiles can also be switched by using the keyboard shortcut Fn + Q anytime using the computer. Also, in the “Power” tab are settings that can be adjusted to improve battery life.
