Finally there is a BIOS update for my notebook and just my luck… Lenovo decides to put a password on the file downloaded from there site. Personally, I have no idea why they would do that, but in any event, a little guess revealed that the password is nothing more than “lenovo”. So I guess security wasn’t a huge option.
I stuck a zipped BIOS / flash utility on this site you can download (I removed the password), or else just download the one from their site and decompress / run with the password “lenovo”. This is the exact installer / BIOS image from their website, just extracted with a password, and re-zipped with no passwor.
As usual, I am in no way responsible for any problems that might arise from you doing this, and you do so at your own risk. Obviously this is for the Lenovo Ideapad U410 / U310 only. The installer is a batch that is Windows only.
