Lenovo T410: Regression in coreboot 4.13?

[Daniel Kulesz]

Hi folks,

I spent a long time trying to get coreboot 4.13 to work on a Lenovo T410, trying various configuration options etc. but it never worked (fan, keyboard LED and thinklight went on, screen stayed dark). I tried even the most basic config, but no luck.

I tried the same with coreboot 4.12 and this seems to work fine.

Unfortunately, this is not my laptop and the owner needs his laptop back asap, so I don't have the time to further debug this issue. Yet, I wanted to report this regression as I I am wondering if anyone else is running 4.13 on a T410 with success?

Cheers, Daniel

Know it may be late, but you should've done a commit dichotomy to find
some bad commit which maybe happened between 4.12/4.13 and could've
been a real cause of your problem.

Yes, definitely - however I didn't really have the time to do that (unfortunately) and had to return the T410. Luckily, I have a second T410, so if I find the time to disassemble it I will try to find the offending commit. If someone has one that is already disassembled this would make the process much easier as it is so much hassle with this model...

Nevertheless I wanted to issue a warning to other people who might try to flash their T410 with the current version.

Cheers, Daniel
