What is a good laptop under 800 dollars? (e.g., Netflix, Excel, PPT, Word, SPSS, SAS, Photoshop, video editing, browsing, little gaming, etc)?

Here are some recommendation that was given to me:

ASUS X540UA-DB71 Notebook

Acer Swift 3 SF314-54-552V

Lenovo IdeaPad 330s Notebook 81F5000EUS

what are your thoughts? Is there other laptops you recommend? If so, what are the pro and cons?

I had a Dell Inspiron Signature Edition (2015) and the hinge was broken off in year 2 and it was never dropped. So, I'm trying to find a good overall laptop under 800 dollars with great built quality, good battery life and good performance. Preferably 1TB Harddrive space, 8+ GB of memory, 8 generation CPU, 13, 14 or 15.6 inch laptop, etc

Connecting old mixer to new laptop?

Simply put, I used to record a podcast with a laptop that had the standard headphone and mic inputs. New laptop has the headset input, making the old RCA to 3.55mm cable set-up either more complicated or entirely impossible. Is there anyway I can still record with this particular mixer and laptop?

How can I turn off the pinch zoom feature on lenovo ideapad windows 10?

This feature is incredibly annoying and inconvenient and I just want to turn it off. I usually see people say to go to the mouse settings and then go to device settings from the mouse tab, but my mouse settings is missing that tab? I also see something about ultranav but I literally have no idea how to get there. As you can see I'm very clueless here. Any help is appreciated!
