Hi,
I've been running coreboot on my T420s for a year or so. It was working fine, but today it isn't booting. When I hit the power button, I just get a white screen. Well, maybe grey and not white, but not the black background with white text like I usually see for my seabios payload.
I tried blindly booting and getting past the disk encryption, but I didn't see the laptop DHCP to the router. I might have botched that though...
Oh, I also had to login for NetworkManager to connect to the wifi, which it did.
I shut the lid and it went to sleep. Upon reopening, the screen came back black with the backlight on. I don't usually put it to sleep, so failing to resume the display may what normally happens.
I hard powered off. When I powered back on, the seabios text was present.
