Good day, everybody!
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.
( as I posted before here: https://www.badcaps.net/forum/welcom...98#post3305798)
It is a P53 20QN-000SGE.
I already upgraded the P53 with 128 GB RAM, 2x 2TB NVMe and the US/RU - keyboard, since it was shipped with a QWERTZ. I am Russian and I have to 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 such stuff, google for <<model>> maintenance manual, and you will find it. https://download.lenovo.com/pccbbs/m...p53_hmm_en.pdf , for example )
For my work / hobby, I need the laptop to have WWAN. I arranged that with the W520, and it works like a charm.
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...
- disable whitelist for hardware, or at least enable that 4XC1D11452 card.
- enable Advanced Menu, just in case, you never know.
- disable Intel ME, since I read and hear al these interesting things about that. I like interesting things, but not such interesting
I would like to make this topic kind of a journal that describes reaching the final target: well working P53 20QN.
Any help would be greatly appreciated, since the dying-rate of the W520 seems to increase, and I need to work..
