I would like to know if there is firmware updates or not for Lenovo Y41O ODD.
now my ODD is not working properly.It works when CD inserts to it but it doesn't work when DVD inserts to it.
So I assume , this problem can solve bu updating firmware of that ODD.
If you all have other ideas for that problem , please let me know.
