Mac mini reassembly fail, broken connector
main board where connector plugs in
broken connector
board after connector broke off.
I was trying a memory and drive upgrade, 8gb and a 250gb ssd. I used the iFixit disassembly steps, but I referred to the Apple Dollar video for tips in reassembly. Plugged the new power supply, pressed the power button and … nothing, no fan and no picture. Before disassembly I at least got the beep for no memory. So I removed the memory one stick at a time. No change. Then the drive came out. No difference and it was back to the way it was before disassembly. Nothing, not even a beep. I checked that the ribbon cable in the back to see if it was seated and it was. Double checked the seating of the board going into the slot on the main board.
I know no one can direct my hands to the exact place and problem. I’m looking for the next steps to troubleshoot. What to do and what to look for. I must have missed something in the reassembly and would like your expertise in how you would work this.
The pictures might show the problem. Seems that the power on button has a connector linking it to the main board. Klutzy me must have snagged the wire in lifting the chassis out. It broke the connector and the link to turning it on.
I have two picures one of the logic board one of the connector. I won’t make excuses. I was attempting a fix and the part of the connector affixed to the main board broke off. Then I tried. removing the main board. I had to remove the sleep light connector. It too broke off. It’s going to be a tricky soldeer that I’d rather send to a pro. Unfortunately I don’t know one.
Esta é uma boa pergunta?

@danj I hope this is the way to message members.
I bought the mini shell for $25 and needed to add back the memory and drive they removed. I bought two sticks of ram @11 ea. Rather than a 250gb drive for $5 I bought an 250 SSD for $25. They aren't the problem.
Sure I could start with another mini or buy a working one. I am looking on eBay now. But I want/need the practice of figuring this out. So how can I check each component starting with power adapter ?

Was the system working before you started altering things?

Sorry, that must have beenn in the other questiion: yes. With no drive or memory, it produced the error beep.

@capwalker666 - What is the beep error ?
Reference: If your Mac beeps during startup
por Dan
No memory.
Then I tired just memory changing which stick
then an ssd.
no power.
It's acting like a dead short between the power supply and first component.
