Hi all,
I’ve gotten my hands on a 2014 mac mini board number 820-5509A. It doesn’t power on at all and I think I’ve found the reason why. Two components are missing from the board. I would like to buy them and solder on the board. Problem is I can’t find schematics anywhere for the mac mini! I’ve attached a photo to indicate the components I need to identify. Appreciate the help! Thanks.

The upper capacitor (marked with a curved arrow) is a 1uF/25V (ceramic, 10%, 0402), and the other one is 2.2uF/16V (ceramic, 10%, 0402).
这个答案有帮助吗？
Thank you so much Lucas! I've taken one 1uF/25V (ceramic, 10%, 0402) from a donor board.... and I've got my hands on a 2.2uF/16V (ceramic, 10%, 0603) as well.... slightly larger case size but I've plenty of space so will solder those two on and report back! Thanks again.
We have lift off :-)

charles, there are no schematics for the Mac Mini available anywhere. you will need to take some measurements from either a donor board or have somebody somewhere check theirs for you.
这个答案有帮助吗？
Thanks, I'm guessing they are capacitors of some sort as they are brown... not black which would typically indicate a resistor. If anyone has a board they can measure up and tell me what it is would be very appreciated. Thanks!
@vogelek23 I noticed you answered a similar query. Can you help at all? Thanks.
