alt Hacker NewsI Ported Coreboot to the ThinkPad X270
Comments
I wonder if this can help with the extremely irritating bug (intentional?) on the X270 where if you give it a third party 9-cell battery, it will raise CPU_PROCHOT all the damn time, and my processor would drop to below 1Ghz clock speeds.
Back when I used to have an X270 I had a shell script that ran on boot which poked a register to disable thermal throttling handling. Not at all ideal, but it made the machine usable in the absence of official Lenovo batteries which they stopped manufacturing pretty damn quickly.
> I can’t recommend libreboot enough, or even heads if libreboot isn’t your speed.
Why though? Not a single reason mentioned in post about why would it be better than whatever stock BIOS the laptop is shipped with.
How did OP debug this without a serial port?
I’ve messed around with porting coreboot on two desktop platforms but always had the benefit of a HW serial port…
Really cool! I wish that Coreboot was available for more recent Thinkpads. I have a Z13 Gen2 which I plan to use until it falls apart, and would love to liberate it with Coreboot. But alas, I can't.
pretty cool work! Though it leaves me wondering if coreboot/bios code can directly interface with thermal-management and battery controller , shouldn't it be feasible to improve upon battery life by exposing some interface to OS, like apple laptops ?
I always wondered, what is the practical advantage of running coreboot on my laptop?
What I would give for a wife that would enjoy tinkering with me.
