Re: IdeaPad 3 14ADA5/15ADA05/17ADA05 Lenovo V14-ADA/V15-ADA Bios

Hi there,

V15-ADA 82C7 power on, charging, fan spinning but remain on blank screen (the same on HDMI out). The original dump attached, but i can't extract de Windows key with BIOSdump2license.exe (serial encrypted mesage for a short time).

So... can anyone patch the latest BIOS: https://download.lenovo.com/consumer...s/e8cn39ww.exe for Serial: PF328XV4 and MTM: 82C7008TIX?

Thank you in advance!

I have patched it by myself, write it into the bios chip but still into the black screen... Can anyone verify it the patched BIOS it's should be ok with the data posted above? Thank you!

Its verified OK, you did a good job. Its worth trying an older version as well,and if that doesn`t work start looking for a hardware problem.

Go to the lenovo support site,enter the laptop serial number.Find the bios update listed under drivers. If the bios version is E8CN**WW (** is the version number) then yes they are compatible.
