Need help with capacitors, resistors, or caps on logic board

While replacing the thermal compound on the heat sinks , I knocked off 3 parts that are either resistors, caps, or capacitors. I need to know what they are and the values so I can re soldier them. I don't have another identical machine available so I can't measure the values off of another.

Not everyone has the dexterity to work on logic boards. You might want to take this to a pro.

Actually I'm doing the repair for a friend. As you can see I have to replace the heat sink as well.

Paul, all three of those components are capacitors.

Reference Designator C8509 is a 1UF 4V 20% capacitor in a 0201 package

Reference Designator C8503 is a 4.7UF 6.3V 20% capacitor in a 0402 package

Reference Designator C8500 is a 4.7UF 6.3V 20% capacitor in a 0402 package

For C8500 and C8503 these should work. For C8509 anyone of those will do. Hope this helps, good luck.
