Yeah don’t use a magic eraser on anything that isn’t like a hard tile. Magic erasers are basically one step below sand paper. They will destroy the texture of plastic if you put any pressure on them. Soap and a towel go a long way. You could also use windex of any other light window cleaner. DO NOT use anything that contains ammonia.
Don’t use alcohol on the screen either. 70% or less is typically fine, but I’d stick to a very diluted mix. Like 50% or less. Google says store bought screen cleaners use Sodium Lauryl Sulfate or Cocamidopropyl Betaine. Idk how to buy those for myself, so I just stick with a teeny tiny touch of dish soap on a lightly damp towel or microfiber. Then follow it up with a dry micro fiber. The store bought stuff works wonders for cleaning the smudges that soap left behind.

Did you go to their parts website? They sell parts for even their shitty(er) laptops.

And yet still not as serviceable/durable as older ThinkPads.
Uh, have you ever replaced the motherboard on older ThinkPads? You have to tear the entire machine apart and it’s a 30+ minute job. Around the time they removed the water spouts they switched to the bottom opening instead of top opening and replacing the main board went down to a 10 minute job. Even just replacing the thermal paste on some older machines required full disassembly.
They may not have water spouts that let you pour a gallon of water through the keyboard, but they do have plenty of plastic shields that prevent water from going further into the computer. If you knock over your soda your computer will probably be fine.

Yes, yes they are.
I’m not qualified to explain this well. But there’s the concept of velocity of money. The higher velocity that’s supposed to mean the economy is doing good. Generally it’s between lots of people so it’s spread out. In this case it’s only between a small handful of companies, and as soon as it starts drying up then bad things can happen really quickly.
I’ve pretty much only ever used headphones when playing games. Never been much of a console gamer, always PC. At this point I almost exclusively use my HD 800s. They’re absolutely amazing headphones and the sound stage is incredible for gaming. Far better than any “gaming” headset I’ve used in the past.
Almost all pcie versions are backwards and forwards compatible. You could put a pcie 5 video card in a pentium 4 machine and it should work.

I’m guessing they’re all just behind an internal hub.

The x870e chipset only provides 2 20gbit ports (type c only) 12 10gbit and 2 5gbit ports. No idea how the USB 4 ports fit into the equation, but I think the 2 are mandatory.
The exact level you charge it to matters less than what the battery ends up sitting at. Batteries are happiest at about 40%, but very rapid get unhappy the lower they go. The closer you can keep it to within the 40-60% the better.
