This probably pretty old thread, thats good cause theres been time to determine things. I just bought this and I wonder were you able to disable the whitelist on it?

Good day, everybody!

My name is Evgeniy. I live in the Netherlands.

Here I would like to log my progress of modifying and unlocking my P53.

I bought the P53 as a replacement for my slowly dying W520, and it needs to at least be able to do the same stuff.

It is a P53 20QN-000SGE.

I already upgraded it with 128 GB RAM, 2x 2TB NVMe and the US/RU - keyboard, since it was shipped with a QWERTZ. I type NL/DE/EN/RUS on daily basis, so that keyboard was a must have.
(P/N 01YP702 or 01YP622, seems to be the same part. Of course with backlight  )

For my work / hobby, I need the laptop to have WWAN. I arranged that with the W520 previously, and it works like a charm.

I remember, I bought a "fully open" bios 1.46 from a guy for a small price. 

For the P53, I could obtain the 5G Lenovo card for a fair price. 4XC1D11452 . I also ordered the antenna set and the SIM-tray from eBay.

(P/N 02DM541 , 02DM493)

... And now, I think, I need to modify the BIOS...

What I would like:

- disable whitelist for hardware, or at least just enable that 4XC1D11452 card.
- enable Advanced Menu, just in case, you never know.
- I am not sure about Intel ME. I read a lot of interesting stuff about it, but also that it improves performance, which will worsen when it is disabled.


Any help would be greatly appreciated, since the dying-rate of the W520 seems to increase, and I need to work..

On one hand, I would like to at least understand how it has to be done. On the other hand, I need a working laptop..
