My father-in-law gave me his laptop he used to order pizza on. Its a older one for sure. Its a Dell Latitude E5440 or E5540. When i download and run the lastest driver from Nvidia it just gives me an error and says my system is incompatable and i am not sure what to do. Most of my ameatur at best expertice is in hardware not software so any help at all even if its pointing me in the right direction will help. Thanks

So i have a Asus q45ua laptop and im into light gaming such as League of Legnds and i noticed that when i have low battery and im plugged in i get next to no perfomace. If i were to remove the plug i would get normal levels of performance in game. I searched around i cant find anyone with a solution to my problem. Anything would be apprieicated. Thank you fro your time.

Good day, I'm new to asking for help online as I am not even sure if I'm in the right place to be asking this question. My lovely Huawei P20 Lite's screen has stopped working and i go my hands on two "replacement" phones, an LG K4 LTE and a Sky Devices phone whose name I'm not too sure of but I assume its a 5.0W . I would like to install a lighter version of andriod just so my experience isn't molasses slow. I've seen andriod go and oxygen OS and lineage OS. My expertise is more on Pc rather than Andriod so I would assume that you can just install anther OS but it doesnt look like thats the case hence why im asking for help. If it's a link to a video or even directing me to somewhere I can ask for help i would appreciate it. Thanks.
