Thank you for contacting Acer America. The refund amount for the version of Windows 8 ML on your system is $61.90US. You will need to ship the system to our repair depot and I will provide that address in a later reply. I need to register the system to you in order to set up the repair. You will need to include any recovery media you have created with the unit. Please provide your street address and phone number, business name if applicable.
