I have a bad part board on this machine and I need to order a replacement, I've emailed Dell support at least 8 times in the past 2 weeks but haven't heard a single thing back about getting one. The part number on the board is CN-OP8477-13740-593-0BE7. I've tried searching around on dells site for it but can't seem to find it listed anywhere. If I could get some help here it would be very welcomed. Thank you.
Do a Google search for "Dell P8477" (the part number you found minus the "CN" and the leading 0 and everything after those 5 characters).
You'll find several companies that sell this board. Alternatively you can call Dell spare parts sales and see if they can quote you a price for that part number.
