    There’s software to check how many mAh most laptop batteres are able to take up and deliver, compared to what they shipped with. Modern ones even have how many complete 0-100 charge cycluses the battery have gone through. You can check if you think there’s something dodgy about the battery. I’ve actually seen laptops factory shipped with smaller batteries than ordered.

    But knowing linux and seeing you had an issue with the power profiles I’d think it’s software related hah. Is there a discrete GPU onboard it’s using instead of the power-saving one perhpas?. Also, did you turn off that awful “dynamic background” on youtube that continually taxes the CPU?

    Something is completely shutting your server off from the internet, despite it having full LAN access. The only time I’ve run into this exact issue was when I misconfigured the firewall on a server, effectively only allowing for local connections. I simply started over by reinstalling Debian, wiping all my mistakes. But it could also be a setting on your router, and without you knowing what changes you made it’s hard to give any reasonable advice.

    These are just shots in the dark, and other might offer better solutions but I’d try;

    1. Boot the laptop into a live session directly from USB. All settings are default. Test again, either wget or maybe ping a website. If it works, it’s the server setup and I’d start over. If not…

    2. Try reversing all changes on the router, give the server a different static IP.

    3. Back up the router configuration to a file, consider making notes of important changes, reset the router and try again. If it STILL doesn’t work you can restore the important settings. If it works, you can reimplement the settings from your notes. (unless we’re talking manually imported VPN certificates and similar lol)

    Sorry I wasn’t able to help you out, I’m hosting from home and it’s a fantastic thing when things

    I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works

    Haha yes, as mentioned. The issue is a setting on your laptop server installation. The simplest thing is just reinstalling and starting over.
