lenovo 720-15ikb 81c7 possibly corrupted bios
#1
Hi,
I have a Lenovo ideapad 720-15ikb (81c7) that seems to possibly have a bricked bios, the device will power on to a black screen spin up the fans for a few seconds and then just sit there with the caps lock light on and the keyboard backlight on.

I’ve finally got round to getting a ch341a programmer, done the 3.3v mod on it and have managed to read my bios off the chip, the issue I’m now faced with is that the file I extract from the chip contains all the intel ME stuff and the bios update file lenovo supply appears to just contain the uefi firmware.

Is there anyway to recreate the bin file with a bios that isn’t corrupted or does anyone have a backup of the same laptop that I could clear out the ME info and embed my laptops details into? I did see a post from 2 years ago for the same laptop requesting a supervisor password removal but the mega link is now dead by the seems.

I have found one site that has a backup for the laptop but the site requested a “account upgrade purchase” in order for me to actually download the file, which I’m not overly keen on sending money to a site I haven’t heard of before.

Any knowledge or help on this would be much appreciated, the original bios corruption happened due to clearing the nvram a few too many times on my opencore hackintosh build for the laptop prior to the knowledge going round that clearing nvram on lenovo devices can end up corrupting the bios.
