Hi, Jschwartz5251,
Welcome to Sony Community!
PCG-8111L is just the chassis number for your unit. To get the exact model name, please visit this link: https://us.en.kb.sony.com/app/answers/detail/a_id/38141/. How did you install Windows 7 Pro?
Is there a yellow exclamation mark Under "Other Devices" in Device Manager or a red "X"?
Regards,
Vincent
