Hi All, I have a 9th Gen Dell Optiplex micro PC motherboard which doesn't power on. When I connect the motherboard with power adapter, it goes into safe mode and turns off. So from info I have gathered online, it looks like there is a short circuit on the motherboard. So can you guys help me with figuring out the issue?
I am new to electronics repair, so my queries could be naive but I am ready to learn.
So I have a multimeter and a solder with me. But I can try to get a variable voltage power supply with a thermal camera as well. From what I seen online, best way is... -

I have tried multiple different Dell power adapters. My Dell... -

Hi guys,
I’m looking for someone in the Northeast to do a full electrolytic capacitor recap on a working Dell Dimension XPS T450 motherboard (it's an Intel 440BX, Slot 1). The board runs mostly fine but is beginning to freeze after warm reboots (turns back on for 30 secs or so and then freezes up but is perfectly fine after 12 hr cool down).
I’d be sending just the bare motherboard (CPU, cards, bracket, battery all removed). I’m located in Chadds Ford, PA and happy to ship within the US.
Looking for someone experienced with older PC boards who uses...07-29-2025, 11:53 PM
