My processor is an i7 640LM. Something i also noticed is that the system runs hotter with coreboot than with stock bios but i don’t know what’s causing that. ---Files-------------------------------- Kernel Logs.md (80.4 KB) Coreboot Logs.md (152 KB) Powertop Screenshot.png (34.5 KB) -- You have received this notification because you have either subscribed to it, or are involved in it.
