[coreboot] Postcode at Lenovo x230

[Elisenda Cuadros]

Hi Rafael,

I have a X230, but this has never happened to me before. Sorry :-( .

Have you tried unplugging, waiting 10 seconds and plugging the CMOS 
battery cable and trying to boot afterwards?


Also disconnect the laptop battery during this procedure.

Regards,

- Eli
