LGA 1150 pin a29 detached from the motherboard.
LGA 1150 pin a29 detached from the motherboard.
I bent some pins on my LGA 1150 board and managed to straighten them, though pin a29 came off. It mentions that pin a29 is VCC, so its removal shouldn’t be a big problem. Since the board is a Dell OptiPlex 9020, could the broken VCC pin be contributing to the issue? I’m trying to figure out why it didn’t work before the damage and want to fix it.
Vcc, vss and gnd are unnecessary details; a few broken parts aren’t a big deal. Share photos of the board and socket. Why did the board fail? Likely because it got dirty. If you left it unused, remove the CMOS battery, touch the CLR CMOS (RTCRST) and power button for a couple minutes, then rinse with water and dry thoroughly. This is my go-to fix for many common issues—dirt often causes problems. No PCI slots or LPC/TMP header found, so no postcodes needed. It has at least one speaker, so a single beep means it posted correctly; multiple beeps usually relate to RAM.
I used an old PSU with this board before; it was malfunctioning. Luckily, the new ASUS motherboard I purchased came with protection and reported power surges. I attempted to reset the CMOS, applied direct power (shorting green and black wires), tried another PSU, but nothing helped. No visible damage, no odor—just silence. My CPU and RAM passed testing and are functioning properly. When I forced power, neither the CPU nor chipset overheated, though I heard a high-pitched noise from the board whenever I connected the PSU (no need to turn on the PC). The board also has PCI slots—what do you mean?
As you increased the power input, the fan began to spin and felt quite responsive since the PWM was functioning properly.
Cpu and chipset lack heat indicates failure. Avoid wasting time on this board—it’s likely dead if there’s no heat from either the chipset or CPU. Fixing it won’t be easy; you’d need significant work beyond just submerging it in water. PCI slots won’t help either, as the boards I saw online don’t have them, suggesting a possible model mix-up.
