Re: Lenovo Yoga 520-14IKB BIOS

The EC chip is a Nuvoton NPCE388NB0DX ,its programmable with the 128KB EC.bin .It is flashed through the keyboard connector,you need a special programmer, Vertyanov Jig , SVOD3 . You can find lots of youtube videos for both programmers usage.

so..at post # 7 you also have a link, click on it, go to post # 1 and use the main and EC bios there..the main bios is 8mb and use the TL 866 programmer for reading and writing ... remove the chip bios on the motherboard, put it in the adapter, and the adapter in the programmer, rewrite it with the bios from post # 1 .... 8mb. find tutorials on the internet how to use it..this video is just a example on how to use the programmer..you can see others, you just have to write the 8mb bios on your chip and stick the chip back on the board .success
