I wish I could undervolt my laptop.

I can't even modify the BIOS due to BootGuard and the keys burned into the CPU.
Hopefully there will be a way to leak/extract the keys someday, as this create real e-waste for fake security.

- csdvrx 4y agoI was thinking more about the recent Alder Lake Lenovo leaks :) Right now I'm fighting with nohz_full and rcu_nocbs to limit the wakes per second, with irqaffinity on top to isolate to one core what must happen so that the others can stay in PC8 when I'm not compiling. I'm down to about 350 on a 12th gen Alder Lake with E and P cores running Wayland with a few terminals, Thunderbird and Edge) but I wish I had the ability to also undervolt to go beyond 4W
