I have a MBP 15" Mid 2010 with the dreaded 820-2850 board. The laptop runs fine without a battery, but it suffers from GPU panic so I decided to replace the C9560. When I removed the board the area under the EMI shield does not look fine to me...as shown. No sign of liquid damage. Can anyone tell me what role those components serve and their value so I may be able to replace them?
