ThinkPad L560 LA-C421P

pass not in BIOS, check chip KBC
Hello!

So to remove Bios PWD from Lenovo L560 the KBC Bios chip must be reprogrammed as far as Ive understood.

Is it possible to take it from a same model laptop (without password) and flash it on a PWD protected one?
Or it must be worked ?

Thanks in advance!

Hello, I need the kbc dump for this Motherboard, KBC is the Nuvoton NPCE388NA1DX, the Motherboard went bad by a wrong bios update, now it does not activate the +5ALW

Hi again,

So Ive programmed KBC chip with this post ECROm but I still have the Password prompt when going to bios.
Here are the original dumps of the first laptop of the 4 I have with bios lock L560

Can I have your support to remove PWD?
Can I apply the same file to the 4 laptops ? (all same model)

Thank you!
