    Lenovo B50-30 working Main and EC bios

    Hello please help me to find working EC and Main bios for this model. I have tried many bios from Badcaps and other websites but it doesn't work.

    Laptop is turning on but no display, consuming 0.25amp and 0.12amp without RAM. I suspect this is EC or Main BIOS error. So to confirm please help me to get both working dumps.

          dspok, your bios version is CN30WW(V2.08). I have extracted main from lenovo update with version CN35WW(V3.01).

          Wish you good luck

                  In my opinion yes.
                  All voltage supply are ok.

                              buy a new chip, or use one from another board ... write it with the bios from item # 5, and stick the chip back on the board ..

                                      the EC bios is in the I/O chip, to program this chip you need a Vertyanov, Svod, etc.. programmer with CH341A you can only program the main bios chip on the motherboard..
