Hi all. Thanks for taking the time to read. Here's the situation. I have several of this model, most locked. Recently purchased a Vertyanov Successor and was able to successfully read and write to the Nuvoton EC. However, erasing then writing did not remove the password. I was expecting to user the lenovoUone tool. I have an unlocked bios saved and was able to write that file. The Bios was no longer locked but the SN info etc was of course wrong. (proof of concept for me at least)
I was hoping that if an unlocked version of my Bios was made for me, I could use that to compare and learn...

Hey,
I just revived this motherboard (fixed no POST, thanks to a BIOS from this thread)

Now there's a supervisor password required on power on. It is stored likely in EC, which is Nuvoton NPCE68BPA0DX (sometimes misspelled as NPCE688).

I've seen some success on reading this chip in thread for Intel version of this laptop here.

I have access to RT809H programmer. Is there any chance of programming this EC with it? If not I guess I need to find someone with vertyanov?

Or maybe there's a way to bypass just power-on requirement by modifying...

Did some more experimenting with the slow read on the NPCE68BPA0DX EC with SVOD4. After launching the SVOD4 software, I would select Nuvoton as program mode, select Read ID, then Config Nuvoton to 384k and check NPCE38/48/58/68. This would result in a very slow read (around 10 minutes) and data would all be E7. Sidenote: SVOD4 will only detect the EC with both battery and power plugged in. Battery also needs to be pulled and reconnected after write to get the system to boot.

If however, you select Config Nuvoton first, then Read ID, the chip is identified but size returns to 128kb,...
