Lenovo #UEFI #firmware bricked itself, messing up the NVRAM during suspend. Black screen only.
We took a fresh image from the website, and the system booted again.

So we patched bac…

I'll be running a hands-on two-hour workstop on #firmware analysis at #DO_BYTE: fahrplan.do-byte.de/do-byte-20

Binary Analysis of Real x86 Firmware DO_BYTE (2026)
Language/Sprache: EN/DE (whatever people prefer / je nach Notwendigkeit) More or less trivially, we can dump firmware from flash chips on mainboards nowadays. But what do we do with it?

We have successfully restored a laptop's #firmware today at DO_BYTE.
The flash part is a WSON, so a pogo pin adapter was necessary, and I had one and brought it today.
Within less than 10 minutes, the procedure was done.
Happy to see another #laptop boot again! 🥳
