Re: Lenovo Z410 to Z510 motherboard

Thx for reply. The 30-pin connector was there, but the zero resistors were not according to the schematic. I soldered them correctly and it's working but without extra num pad.
I think the same thing about firmware, but dont know how to force flash the Z510 EC and if it is even possible to do it from an os or some bootable device.

Hello, i bought a new motherboard for my notebook lenovo z510 from China, but they sent me board for Z410 and i have got two main problems.

First, my wifi isn't working. I was searching on internet and i found that everyone who want change wifi card need unlock bios first. Maybe it could also help me.

And the second problem, more important to me, is with the keyboard. The keyboard hadn't worked at all then i found out that there are zero rezistors that can setup the keyboard connector. Now I'm in a state that the whole keyboard works except numeric pad.
