έχεις βάλει στο system panel της mobo στη θέση lock keyboard δίpino, ένα διακόπτη που δε θα έπρεπε να μπει. Κοίτα το manual της mobo soy και ξαναβάλτα.

Μπα την VNF3-250 έχω και δεν έχει κάτι τέτοιο......

οκ βρήκα λύση...

Turning Legacy USB Mouse support on in bios locks keyboard o. Thank goodness for the internet, it just required the correct google query, which was google:Chaintech VNF3-250 keyboard locked.

This told me that when you turn on USB Legacy Mouse support in the BIOS, then you get the Post Code 7C. Keyboard is locked: Unlock message.

Seems like this is some strange BIOS interaction, so the solution is turn off legacy USB mouse support (whatever that is) in the BIOS and then use new mice (I think that means a true USB mouse, rather than one that is really serial but has the pin adapter to make it fit in a USB slot).

some report that if you update to BIOS version VN120729 this also resolved the problem.
