What has disappeared and what remains?
Hello, I understand you're looking for guidance. While setting up a new heatsink on your Lenovo ThinkCentre M93P slim, the short circuit sequence repeated and the device stopped working completely. You mentioned using a different PSU from your old slim 120W unit, but noticed mismatched pin counts—14 vs. 20 pins. After flipping a power strip switch and pressing the button, there was no response, though it worked fine an hour ago. Since you're unsure about parts to keep as an OEM, I'll suggest checking the motherboard manual or contacting Lenovo support for compatible components.
It seems the Lenovo board doesn’t follow the usual ATX layout, so putting an ATX power unit in place caused issues. Expansion boards, the processor, memory, and drives should still function. If things went well, the board might have protected everything by shielding it from damage.
Yeah, but at first it just didn't start with the original psu
The motherboard has 14 pins. I hope my repair shop stocks the necessary parts, since I'm saving for a replacement and don't have funds. If not, I'll pass it on to a friend. He requires these components because his system is an Athlon 64, and the PSU is from a Pentium 4 setup. Should the PSU fail—either due to a proprietary issue or a new case—I'd need both the motherboard and PSU.
I don’t understand, I hope the CPU and RAM function properly so you can remove their components.
The brief sequence happens when the board powers up, fans start, a short beep occurs, then it restarts. This moment is completely cut off this time. After three attempts, the fans ceased spinning and cut off the power to the motherboard.
No, not necessarily. The question asks if the pins align with the standard ones you installed, but it doesn't confirm whether they were originally intended for that purpose.
