Default ideapad 320 14/15/17 IKB DG421 DG521 DG721 NM B242 rev. 1.0 schematic

Hello! I am asking for a schematic of the ideapad 320 14ikb mainboard, specifically the dg421 dg521 dg722 nm b242 version. I have searched online, but am unable to see one for the kaby lake version. I have no need for the BIOS. Thank you!

I have a problem with same board, it starts only if I reset bios(pull out battery and bios battery) but after I shut it down it doesn't start again only if I reset it ...

I can make it to reset every time when I shut down but isn't a nice method ...

anyone had this problem?

thanks!
