Is CH341a (w/volt selector) with another adapter ok? Any better?
NeoProgrammer v2.2.0 should be used to dump bios from the chip?

Tnx for the reply, Vesko! 😉

I didn't make any bios backups previously, so is there a way to extract bios backup/info or something else can be done?

Hi everyone! 😀

Myself like most folks here a problem with BIOS as well (black screen, laptop boots up, LED's work), so I would like to ask if the [B]Bios file from the post #12[/B] would help my model?

I have tried all known fixes with unplugging CMOS, ram, battery drains... which ultimately led me here, considering the wide issue with this model.
