No. They have a trial of 100 one-time searches, but that’s it.

The extended support updates aren’t available to end consumers but is a paid product for enterprises that need more time to update.

The big reason I switched back to Nvidia was because I wanted to play with some local AI models, and doing that with AMD cards was quite difficult at the time (I think it’s improved a little, but still isn’t straightforward).

That’s hard for me to answer because I’m usually at home plugged in, and I set the max charge in the bios to only 65% so the battery will physically degrade slower (I don’t need the charge). A few hours is really all I can say with any accuracy. Worth noting a few things -

1. Since I bought my laptop they came out with an improved battery I could upgrade to, so you’d get a better experience.
2. I believe(?) battery life is improved a fair bit at least with the AMD ones; less sure on the newer Intel ones.

I will say that if long battery life is your #1 concern this may not be the laptop for you.

I have a 12th gen Intel Framework running Arch. I love it, although as others have pointed out the battery life could be better. Early kernels shortly after release had some incompatibility issues that required specific kernel arguments to fix. Also I had to blacklist the light sensor as it conflicted with the brightness function keys.

The Arch wiki has a page with details on Framework laptops you may appreciate looking at.
