DO NOT BUY FROM THIS COMPANY!!! I ordered a "new" inverter board and got a used one "not even refurbished" that quit working after 2 seconds. I have contacted them twice and still have yet to get a response. They are impossible to get a hold of as there is no address or phone # listed on their site and they apparently don't pay any attention to any emails they are sent. I have since ordered from another company and my computer works just fine.
