Hi guys,

Today I pulled 5 Lenovo T420 laptops out of a bin at the rubbish tip, and they're old school laptops and they're all locked with a supervisor password.

In the past I've unlocked similar Lenovo laptops, often I used the trick of shorting a few pins together on the chip on boot to get into the GUI and overwrite the config but it doesn't look like that is working with these laptops. I guess Lenovo fixed that trick? I have unlocked some other HP laptops by reading the chip, running a patch and re-writing back.

But I can't work out these T420...
