Hi,
Do you find any yellow exclamation mark in the Device Manager? if so, please let me know the hardware ID for the same. Also, please make sure that you have performed complete windows update after upgrade to windows 8.1
Please reply with update.
Although I am an HP employee, I am speaking for myself and not for HP.
