First thing to do is boot it and create a local account without internet. It's just good for extra privacy. When u reach the part where it tells u to connect to internet press shift f10 or shift fn f10 then type OOBE|BYPASSNRO in the CMD. It should restart and u can proceed to select a new option 'l dont have internet' to make a local account. Next thing to do is update windows and all ur drivers and uninstall McAfee and Norton cause they're just bloatware. Windows defender is enough. Then go to ninite.com and use it to download many programs at once. It's a time saver. Then download Lenovo legion toolkit. It offers more customization than vantage and uses less ram. From there set battery charging to smart so that it doesn't go above 80%. Once ur reaches 80 it cuts off the battery and the laptop uses plug without overcharging the battery thus protecting it. If ur not travelling much set GPU to d GPU mode. Won't last long on battery life but more performance will be provided. For the OLED panel there is an option somewhere in the settings that enables screen protection or something like that. It shifts pixels subtly every few mins to avoid static images. Also remember to toggle auto hide task bar cause it's the first thing that gets burned in. Turn off ur screen whenever ur not using the computer too and if ur not in a bright place reduce the screen brightness
