Lenovo B51-80 works only with HAP #122

Hi, I tried to apply me_cleaner on:

-Model: Lenovo B51-80 -CPU: i5-6200U -ME version: 11.x -External programmer: ezp2010

Tried with both -s/-S, works only with soft disable (-s). Otherwise the PC won't boot. No screen. I'm happy with this, if you want more informations for debugging I'm glad to give you.

Good stuff! I have the exact same machine. Is the SPI flash easily accessible?

An4cl3t0 commented 6 years ago

Not so much. The SPI is over the wireless card, you can see it removing the back panel, but you have to cut the plastic or disassembly to access with the clamp.

I do not know about that specific model, but most Skylake (and newer) Lenovo sytems have Boot Guard enabled (see the wiki page for some more info), which could be why -S is failing.

Thanks. This is probably the problem. Closed.
