This isn’t a question but rather a solution to a problem I couldn’t find anywhere online, apologies if this is the wrong community.
If you have a Lenovo laptop (in my case a T14 thinkpad) and your display dims after about 30 seconds, no matter what you specify in Windows settings, you might have to disable the “Zero-Touch-Lock”. You can do this in the Lenovo Vantage Software (in my case called “Lenovo Commercial Vantage”) in the menu “Smart Assist”.
Ohhh yeah that’s super stupid, my Dell Inspiron 14 5405 has a similar “feature”
